TRANSCRIPT
  • DORIE CLARK: Hello this is Dorie Clark and I am here on behalf of Newsweek. We are doing a special series on creating the economy of the future. And this week our topic is the global challenge of climate change.

    We are interviewing Dr. Fatih Birol. He is the executive director of the International Energy Agency. And we're going to be talking about the latest developments and ways that we can all prepare for the challenge of climate change in a special series presented by the government of Japan.

    Dr. Birol, welcome and great to have you here.

  • DR. FATIH BIROL: Thank you very much. Thank you.

  • CLARK: Excellent. So I'm looking forward to a wide-ranging conversation with you about climate change. The very first question that I have is as a layperson,

    I know that a number of years ago, there was a big drumbeat, political gathering, saying that we should all try as a culture, to reduce our carbon dioxide in the environment to 350 parts per million. And that if we, if we did not reduce it to that level, basically, we were all going to be in really dire straits.

    Now, as I understand it, even in 2020, when, when people weren't driving, people weren't flying, people weren't going places, because of the pandemic, the amount of carbon dioxide in the environment rose to well above that.

    I believe it was 412 and a half parts per million. So are we completely in a dire situation here? Is there any way out of this? What is your perspective on this?

  • BIROL: Thank you. So, we are definitely not on the right path for our planet because when we look at the numbers, which we do at the IEA, our emissions year on year, they are increasing. And they are increasing and reaching dangerous levels.

    What does it mean dangerous levels? It means we will see much more extreme weather events. And those extreme weather events will be much more intense than what we had before. This will affect everybody. This will affect Africa, this will affect Asia, North America, across the world. And the weather events will be unpredictable. And here, energy sector plays a central role.

    Why? Very simple. The 80 percent of the emissions causing climate change comes from the energy sector 80 percent. So it means without fixing the problem in the energy sector, without reducing the emissions drastically in the energy sector, we have no chance whatsoever to have a planet, which is more or less like today, in the next few years to come. And a huge challenge for this but also next generations.

    The way to solve this problem goes to finding clean energy technologies, clean energy choices for producing and consuming energy. So this is the challenge we are facing today.

  • CLARK: Thank you so much. We're here with Dr. Fatih Birol. He's the executive director of the International Energy Agency. You can learn more about their work at IEA.org. And Dr. Birol has has a great distinction, this is one of my favorites here for the Financial Times named him the Energy Personality of the Year. So that's got to be one of the cooler honors in the energy world. Congratulations on that.

    So Dr. Birol, one question that I have for you, you're mentioning that 80 percent of these emissions are coming from the energy sector. One of the things that's of course, been in the news recently is Russia and the conflict in Ukraine.

    There's a lot of speculation that this may end up disrupting the global energy supply. Already gas prices in the United States are going up pretty dramatically. I believe that the price now is over 3.50 per gallon, which is quite high and about $1 per gallon more than it was even just a year ago.

    And we recently have seen that Germany is cutting off the Nord 2 pipeline. So it seems like there's going to be some real potential for disruption in the marketplace—given geopolitical events. How do you see things shaking out in the near future?

  • BIROL: So energy prices are high, not only in the United States, but also in Europe, in Asia, India, Japan, Korea, everywhere. And this is mainly driven by the very fact that after COVID, you mentioned the COVID crisis, global energy demand increased very, very strongly. And the increasing demand was not met with enough production supply, oil and gas.

    For example in Europe, we have huge gas prices, natural gas prices. The reason is very strong demand coming after COVID economic activity became stronger, strong economic activity means more energy. But there was not enough gas delivered to Europe, mainly by Russia. Russia is the main exporter of gas to Europe.

    But as a result of the Russian policies, Russian exports to Europe declined. Why one wanted to see even higher than previous levels, it was much lower than the previous levels. As a result of that we have seen an artificial tightness of the markets and this bumped the price up.

    So while we had an energy vert, why we had a major challenge of climate change, now we have another problem, which is the geopolitics. The recent messages and actions of Russia meant that the energy and geopolitics may well be much more interwoven in the next months and years to come. And it will definitely complicate the energy questions in a difficult way.

  • CLARK: Thank you, Dr. Birol. This is Fatih Birol. He is the executive director of the International Energy Agency joining us as part of our special Newsweek series on creating the economy of the future. I'm Dorie Clark. And if you're tuning in live, please feel free to type into the chatbox and let us know who you are, where you're dialing in from, and any questions that you have for Dr. Birol on the global challenge of climate change.

    Now, Dr. Birol, one question that I have is nuclear in the role of nuclear power. This is something that for decades has divided environmentalists some people say that this is really critical to the path toward clean energy. Other people scarred by Three Mile Island and Chernobyl say that it's just too dangerous. What do you think about the role of nuclear power in climate change?

  • BIROL: Yeah. So, when we look at the future, we have of course, in the future, we will have still oil we will have still gas will have other energy sources, but future is electric.

    Electricity will dominate the way we use energy, we consume energy. And where will the electricity come from?

    So, I would say a big chunk of the electricity will come from renewable energies, solar, wind, hydropower and others. But I also see an important role for nuclear power in the countries where it is accepted.

    The issue with nuclear power is it can generate electricity, uninterrupted electricity, with no emissions released. It is a clean electricity generation source.

    And as you rightly mentioned, as a result of several incidents, the last one being Fukushima, we have seen nuclear energy— appetite for nuclear energy went down. However, as I have recently stated, I see nuclear is going to make a comeback, strongly.

    First, there are countries who have now prioritize nuclear power in their energy plants, United States, Canada, France, where I live if President Macron came with a very strong nuclear program, but also Netherlands to new governments and Netherlands, in a China, India and several European countries are pushing the nuclear power.

    Also driven by the volatility of the natural gas markets, it also reminded the several policymakers and also citizens that nuclear power, if you have it at home, you are not a part of the geopolitical games we are seeing. But in addition to the traditional nuclear power, we have the systems power plants we have, there is a new nuclear technology, which we call small modular reactors.

    What does it mean? It means they are, their size is much smaller, easier to build. Their waste issue is easier to tackle. And also they are much easier to finance in a short period of time.

    One of the biggest challenges of nuclear power, in addition to what you said, there is a there was a bit of a hesitance from the citizens in some countries not everywhere, but in some countries.

    This is in addition to that challenge, the nuclear power plants, the classical nuclear power plants are difficult to finance because they require huge amount of financing.

    And they to construct those nuclear powers you require many, many years. But with these small modular reactors, I mentioned to you, their construction time will be much shorter, and you need less finance to bring them to the market.

    So I expected that nuclear power will be an integral part of the future electricity mix. Even though the lion's share of our electricity generation in the future, will be belonging to renewable energies and I see a good marriage and a happy one, I should say, between renewables and nuclear power.

  • CLARK: Thank you very much. We're here with Fatih Birol. He's the executive director of the International Energy Agency. And this is a special series by Newsweek on creating the economy of the future. I'm Dorie Clark.

    So Dr. Birol let's turn for a moment to renewables. Now, for many years, the challenge with wind power with solar power was that it was just too expensive.

    And it costs too much to create energy from those sources to be economical without a lot of subsidies. That situation seems to have changed dramatically.

    And the costs have really come down. Can you talk a little bit about the current state of renewable energy and how that factors in to some of the energy mix that you're seeing for the future?

  • BIROL: Yeah, you're right. Wind and solar were very expensive 10 to 15 years ago. But as a result of, as we call it, learning by doing. So the more we bring new solar electricity solar panels to the markets, the company's manufacturers learn to produce them cheaper.

    Today, solar energy is one of the cheapest source of electric generation in many countries. Ten years ago, when we talk about the solar, it was more or less a romantic story. What does that mean romantic?

    It's a main business in many countries and in fact, when we look at the numbers, last year, about 60 percent of all the new power plants built in the world were solar, followed by wind.

    So this is not necessarily to address the climate change issue. It is basically because of the cheap source of electricity generation. So I believe is solar and wind will be key drivers of the future electricity generation everywhere in the world, in Africa, in India, in Asia, in North America and Europe.

    But the challenge with solar and wind is their availability is nature bound. So if you don't have sun, you don't have electricity basically, to put in simple terms. If you don't have wind, then you don't have electricity.

    Therefore, nuclear can play a good role here to complement the solar and wind latest generation. Because for nuclear, you just push the button and it generates electricity for you 24/7. And I think a while the renewables will have the lion's share nuclear, in the countries where it is accepted, it can play an important role as well.

  • CLARK: That's really interesting. Thank you very much, Dr. Fatih Birol, executive director of the International Energy Agency. He also chairs the energy advisory board for the World Economic Forum.

    So a question that I have is, I would love to hear more about your perspective on experimental strategies around both energy and climate change.

    We sometimes hear ideas that sound appealing, although a layman may wonder how technically feasible they are about things like burying carbon dioxide deep in the earth, or perhaps newfangled methods of energy creation.

    Can you talk a little bit about what you see on the horizon, both in the energy sphere and with regard to protecting against climate change?

  • BIROL: So there are numerous such candidates of breakthrough technologies. Some of them see the light of today, many of them don't. But a is some of the rather promising ones, you mentioned one of them, which is capturing the carbon and putting it under the earth.

    We call it Carbon Capture and Sequestration Technology, which could be very helpful to use fossil energies in an environmentally friendly way. Because the issues today, why coal or gas and oil seem to be creating challenges for climate change, because they are emitting carbon dioxide emissions.

    If this technology, the carbon capture technology, during this process, why you use oil or gas or coal, can suck up the carbon from them and put it under the earth if they can be used in an environment-friendly way, we could have a major advantage in terms of our energy sector at the same time addressing climate change.

    Another one came in several years ago, many people thought it will not be a good solution, which is the electric cars because they were very expensive. But today, we are seeing the electric cars are becoming a mainstream transportation instrument in many countries.

    In China, 20 percent of all the cars sold last year were electric cars—the same in Europe, about 20 percent. I expected in the United States very soon, we will see electric cars will be seen more frequently on the roads because several car manufacturers now prioritize electric cars as the next model they want to put in the market.

    So there are many disruptive technologies. Some of them, we see the light of today, some of them will not. And the criteria here is whether or not they're economic and they make the life of the consumers more comfortable, more convenient, and at the same time whether or not they will be part of our fight against climate change.

  • CLARK: Thank you very much. We're talking about the global challenge of climate change as part of a special Newsweek series on creating the economy of the future. We're here with Dr. Fatih Birol, executive director of the International Energy Agency, you can learn more about their work at IEA.org.

    Dr. Birol has been named by Forbes one of the most influential people in the world of energy.

    And Dr. Birol, I'm curious about the role that the pandemic played in all of this. We all know that, especially during 2020, parts of 2021, for most of us, fuel usage, energy usage went down. We weren't driving into the office, we weren't flying and traveling as much because there were global travel bans.

    Certainly, that impacted in many ways, energy usage. Did that actually allow for a bit of a reset? Or what would you say are the impacts of the pandemic on these issues? Have we already rebounded to where we were before? Or, has this allowed us to begin to take stock in some way?

  • BIROL: To be honest with you, the bad thing about my job is I have to be realistic. I have to believe in numbers rather than the hopes and the feelings during the pandemic. When the emissions went down, because of the reasons you mentioned, we didn't travel. The economic activity event down, and therefore emissions went down.

    Many people thought, many commentators, now we have seen that we can save the planet, we learn from this and it will be a gain and we'll look at the future, it will be such a life. And I said, unless governments take the necessary measures, people will go back to what they were doing before.

    Not that I don't have trust in the human beings, but this is the unless you give a signal to the human beings they behave, what is the best solution for them. And today, in fact, unfortunately, emissions today are worse than before the pandemic—much higher than that. But to balance it with an optimistic note, I also see that as a result of what is happening in renewables.

    What is happening with the electric cars. What is happening with the lack of efficiency, digitalization measures? What is happening with these small modular nuclear reactors, I see that a new global energy economy is emerging.

    So this is, you cannot stop this. So, I believe the next chapter of the global economy will belong to clean energy technologies.

    And the countries, or companies, who are not able to read the game, what is happening, the transition here may very well be in a disadvantageous position, and may be locked in with the obscure, absurd technologies, and will not be part of the new chapter of the clean energy system of the future. So we have to see what the future is what today's, and what the past was.

  • CLARK: Really good point. Thank you. We have a question from a viewer and if you have questions, please feel free to type them into the chatbox for Dr. Fatih Birol. We're talking about the global challenge of climate change. But Adnan was curious.

    Do you think that the Russia and Ukraine conflict will cause countries to reimagine their energy policy? Might this actually be a net positive? Because countries that are faced with a specter of disruption may decide to make different long-term choices? What are your thoughts?

  • BIROL: Adnan, this is an excellent question. Russia's act in the last few days. Of course, this is not good news for the peace. This is not good news for geopolitical stability. This is definitely not good news for the Ukrainian people, also for the Russian people.

    But this may bring a shock for the European governments, especially for Europe, which may lead them to redesign their energy policies.

    Because the gas is used a lot during the winter times for heating purposes, we are coming slowly back to the end of winter. But next winter will come. And if Europe still is depending 40 percent of this gas from Russia, next winter, we may see the same movie again.

    Therefore, it is now time for Europe, is an important wake-up call, to redesign and reprioritize their energy policies—look at the other options that they have.

    Here, again, come back to the renewables, hydrogen, nuclear power, energy efficiency, all of these options, which on one hand the improve the energy security, but on the other hand, prepare those countries' economies for the next chapter of their energy systems.

    So at the end of the day, while it's very bad news, what's happening today in the geopolitical context for the people of Ukraine and Russia and elsewhere.

    It may provide a silver lining for the European energy policy playing a wake-up call, a very strong wake-up call, for the governments for the energy policy design.

  • CLARK: Really helpful. Thank you very much Dr. Fatih Birol. He's here for a special series that Newsweek is doing on creating the economy of the future. I'm Dorie Clark, and Dr. Birol we have a question that came in from a viewer.

    Eric is actually curious and wants to know if you can speak a little bit more about hydrogen fuel cells. For those who are not familiar with them, what are hydrogen fuel cells? And what role do you see them playing in the future of clean energy?

  • BIROL: So hydrogen is an old technology, but it became more fashionable recently. When I look at it, talk with the governments around the world. Almost every government has a hydrogen strategy. Everybody loves hydrogen.

    It's very unusual in the energy world because there are always different views. Some people like this technology, the other one dislikes it—but when it comes to hydrogen—everybody likes hydrogen. And hydrogen fuel cells can be another important alternative to our current cars.

    We have in the world about 95 percent of the cars, which is which we call internal combustion engine cars, the cars we are driving around the world today. And hydrogen fuel cells can be another option in order to replace current cars around the world, in addition to electric cars.

    Many companies around the world car manufacturers, in addition to electric cars, they are also having some new models, which can be run by hydrogen. And this can be also another alternative to our current car choices.

  • CLARK: Thank you very much. So another question that comes up often when we talk about climate change treaties and international cooperation around energy is questions of equity with regard to developing nations.

    Many developing countries look to the global superpowers the developed economies and say, it isn't fair, you were able to build up over, over decades over hundreds of yours on the back of cheap energy of coal and other things that that are perhaps not clean energy sources, but were affordable and available.

    And now you're asking us to adhere to environmentally strict standards now that there is a global problem.

    Obviously, we all want a cleaner environment, we want to prevent climate change. But how do you think through some of these equity considerations with regard to developed versus developing nations?

  • BIROL: I think that point of view is a very legitimate one. The current climate problem is not a result of this year's or last year's emissions, it is an accumulation of carbon dioxide in the atmosphere since 100 years.

    For example, during the Industrial Revolution in Europe, we use a lot of coal, and the atmospheric emissions—they are still there. You mentioned the 350 ppm, some of them are coming from those days from Europe, from North America, and also some of them now coming from China, and they are in the atmosphere.

    And now we have to clean it up. And the cleaning up means all countries should be part of the solution.

    So the dilemma here is the following: One tonne of emissions going into the atmosphere from Jakarta, or from Detroit, or from Paris, or from SoCal, or from Johannesburg, it has the same effect on everybody.

    Emissions don't have a passport. So for example, in Europe, if we bring the emissions down substantially if the emissions are still high in the rest of the world, Europe will not be immune to the effects of climate change.

    So this is a race against time and it's also a race that if everybody doesn't finish the race, nobody wins the race. So, therefore, it is very important that the developing countries' decisions in terms of energy are also preferring the clean energy options.

    But many developing countries do not have the means to invest in clean energy options and here, I think it is a moral duty and financially, also, it makes sense that the advanced economies rich countries provide support to emerging countries in order to help them to mobilize clean energy options, such as renewables efficiency, and other clean energy options.

    And at the same time, they marketed development banks, such as The World Bank, the regional development banks should provide a catalyst role in order to mobilize investment in the emerging world. Those countries cannot be left alone in the fight against climate change.

  • CLARK: Thank you very much. We're here with Dr. Fatih Birol. He's the executive director of the International Energy Agency, you can learn more at IEA.org We're here talking for Newsweek about the global challenge of climate change.

    Now, a question on my mind, Dr. Birol, and maybe others as well, is the question of entrenched interests here. Obviously, there are many very wealthy companies that have built up over time their oil companies through gas companies, their coal companies, they make a lot of money from selling energy sources that that are not clean that are heavily polluting.

    I'm curious, in terms of your experience in what you're seeing out there. One would imagine that there would be a lot of resistance to making the change to cleaner sources, which may prove potentially to be less lucrative.

    I'd love to hear your thoughts about this transition, and what role companies are playing? Has there been a lot of pushback, or are there actually bright spots on the horizon, where companies are stepping up to help enable the transition to cleaner energy sources?

  • BIROL: So you're right there, oil, gas and coal companies, some of them are rather hesitant to be a part of the Clean Energy Transition. Some of them are, to be very frank, pushing it back.

    Because a company's job is to make money when you look at the fields of a there, but a and these companies are not only in the Western world.

    They are western world companies, of course, but companies in the Middle East, in Russia in, I don't know the other parts of the world, all the companies, of course, they want to make money.

    However, I can assure you that no company, but no company, will be unaffected by clean energy transition. It is coming, whether they want or not. You can cut the grass, but you cannot stop the spring from coming.

    So this is coming. I am seeing this every day when we look at the numbers. And there are some of the companies I should be very frank, they are also trying to transform the company's budgets, strategies, to be compatible with the clean energy transitions. And we need them.

    Because those companies know how to manage huge, big projects, engineering projects. They have deep pockets. They have expertise on different technologies. Some of the technologies you just mentioned, for example, carbon capture and storage, it's a very complicated, but a critically important technology.

    If the energy companies were to dive into this, and promote those technologies, this will be good for their business, and they will be also on the right side of the history.

    And I can tell you that I see many companies, energy companies, in addition to their jobs of main jobs of oil, gas and coal production, they are an increasingly interested in the carbon capture and storage, offshore wind in solar energy and others. But if you ask me whether or not they say main trends in the energy companies, I will say no.

    Some companies are doing a better job than the others. But I would also warn those companies that they should really be careful. If they stick very much with their traditional business, their assets may well be left stranded in the future. And they may have some major financial losses as well.

  • CLARK: That's an important caveat. We're here with Dr. Fatih Birol. He's with the International Energy Agency. And this is Newsweek. We're doing a special series on the economy of the future. So I am curious.

    Dr. Birol, you have actually been with the International Energy Agency for multiple decades, you've been involved very deeply in this field. I would love to get a sense from you have a longitudinal perspective.

    Over the past several decades, obviously, in terms of climate change itself, and we were talking earlier about the parts per million of carbon dioxide concentration, which is considered a kind of warning signal with regard to global warming. That's moving in the wrong direction.

    But I'm curious is everything moving in the wrong direction? How has the cultural conversation changed around issues of energy and climate during the time that you've been involved in the field?

  • BIROL: To be very frank, in the way I look at the last 20 years, I did not see a major change in terms of thinking as far as the climate change concern, until last few years. There was, of course, activities.

    There was also attention was paid to climate change, but it was not a major or determining factor when it comes to energy policy decisions, as far as climate change is concerned. But in the last few years, I am seeing that the interest in climate change is growing.

    There are two reasons for that. One, the governments have understood how important it is to preserve our planet. And this is very important.

    And here, I should say that not all the governments suddenly discovered climate change, but there are different factors such as the youth played a critical role here, governments to think in this way.

    Second, there were several extreme weather events, as a result of is designed to say climate change, climate change reminded itself to us is a major threat for all of us. And these two factors were combined with the very fact that several clean energy options are becoming economically viable.

    Solar, wind, electric cars, efficiency, some of the nuclear plants and others—so as a result, the last 20 years, I didn't see much. But in the last few years, there is a growing interest in the energy policymaking in terms of taking climate change into consideration when you make a decision. So this makes me hopeful for the future.

  • CLARK: That's certainly good to hear. And amidst all of this, it's perhaps easy for an individual to feel a little bit overwhelmed. Obviously, there's not a huge amount that one person can do to impact things like global energy usage.

    But I'm curious if you were advising someone who is a concerned citizen, about something that they could do some steps that they could personally take an influence that might in some way make a contribution to fighting climate change. What would you recommend for that person? What would actually be useful?

  • BIROL: I can give you two things, one, a political and one a daily life. Particularly I would vote for the government's political parties, who pay attention to climate change in a realistic way. So I would be, I will be taking this climate change sensitivity of the political parties when I put my vote in the elections is one.

    As a person, I would suggest to them what I am doing, for example, in terms of transportation, choose as much as possible public transport.

    And if you have to buy a car, private car, I would go for electric cars or hydrogen cars in order to reduce the carbon footprint because the transportation sector is definitely one of the most polluting sectors.

  • CLARK: Very helpful advice. We are beginning to wind down our conversation. We probably have time for just about one more question. This is Dorie Clark. We've been here on behalf of Newsweek as part of a special series throughout the month of February, sponsored by the government of Japan.

    We've been discussing creating the economy of the future and today's topic is the global challenge of climate change. Speaking with Dr. Fatih Birol, executive director of the International Energy Agency.

    Dr. Birol a question that I love to ask policy experts such as yourself, if you ruled the world, if you had the proverbial magic wand, and you could actually make a policy change, you know, maybe not 10.

    But if you could make a policy change unilaterally, that you felt like would make the biggest difference in terms of improving our transition to clean energy sources, and making, you know, helping to fight back against climate change, what would that be?

  • BIROL: So when you say a, you mentioned Japan, for example, when I think of Japan, and the energy policies or energy history of Japan, innovation was a very important factor in terms of Japanese energy achievements.

    So if I get a chance, globally, I would love to see that all countries around the world would pay enough attention to research and development of clean energy technologies, and pushing the magic button of innovation so that we can have technologies, which are clean, which are affordable, and a which also helps us not to have some geopolitical tensions we have now.

    So I wish that the many countries around the world would provide enough funds for the research and development for clean energy technologies, such as Japan and other countries.

  • CLARK: Research and development is certainly going to be an important part of the picture. Thank you so much for that. We're here with Dr. Fatih Birol. He has joined us. He is the executive director of the International Energy Agency, and we've been talking about the global challenge of climate change. Thank you very much, Dr. Birol. And thank you to everyone for tuning in.

  • BIROL: Thank you, bye-bye. Thank you.

(USA PBS NewsHour) Alarming new climate report predicts ‘catastrophic’ global wildfires in the coming years

PBS NewsHour - William Brangham

There's grim new reports about potential causes and effects of climate change.

The United Nations Environment Program has projected intense wildfires linked in part to climate change could increase 50 percent by the end of the century, and the International Energy Agency said energy sector emissions of methane are 70 percent higher than governments claim.

William Brangham reports.

REPORT TRANSCRIPT
  • Judy Woodruff: As we mentioned earlier in the program, there have been several alarming new reports that the climate crisis is getting worse and coming on faster. From intensifying wildfires, to methane leaks, to rising sea levels, the news is grim.

    William Brangham is here to walk us through some of the latest.

    So, hello, William.

    Let me start with this report from the U.N. about wildfires. It says that we are going to see catastrophic wildfires in the coming decades.

    Fill out more of the picture for us.

  • William Brangham: That's right, Judy.

    This is the first time the U.N. has looked specifically at wildfires. And, as you say, they argue that, because largely of climate change, catastrophic wildfires will be happening globally, and they will be ramping up in the next few decades.

    And it's not just places that have become somewhat accustomed to them, like Australia and the United States. It's places not accustomed to them, like Siberia and the Arctic and Tibet. The U.N. says climate change is the main driver here. This report said the heating of the planet is turning landscapes into tinderboxes.

    We certainly see this here in the U.S. There's this megadrought happening out West that is the worst megadrought since the medieval times. But there's another issue that is driving this that the U.N. says, and that is the way we use land. Agricultural practices, forestry practices have also exacerbated this, so that, when a fire does start, it's worse.

    And this is also, as we know, a huge health issue. Ask anyone that has lived anywhere near a wildfire in the last few years. The sky turns orange. You can't go outside. You can't breathe. We know that smoke is dangerous for human health. And that smoke travels hundreds and thousands of miles. So it is a growing, growing issue.

  • Judy Woodruff:

    And part of the report, William, I understand, does address ways to deal with growing threat.

  • William Brangham:

    That's right, Judy.

    As you might imagine, curtailing greenhouse gas emissions to reduce climate change is the single biggest thing we can do, less oil, less gas, less coal. But, as I mentioned with these land use issues, there are better ways that you can manage the landscape, not letting people move into tinderbox areas, farming in a smarter way, managing forests in a smarter way, using prescribed burns in a smarter way.

    So there are things that can be done. It's not hopeless, but we have got to start acting.

  • Judy Woodruff:

    And then the second report, William, out today from the International Energy Agency, the IEA, on methane emissions, saying that they are coming far worse, far larger than had been expected.

    Why does this matter?

  • William Brangham: It matters because methane is one of the most potent greenhouse gases out there.

    It is much more potent than carbon dioxide. It doesn't last as long in the atmosphere, but it — when it is there, it is much better at trapping heat. And the IEA report pointed out that the countries that have been trying to track their methane emissions have been underestimating those emissions by about 70 percent, which is a huge — it's not just a rounding error.

    That is a huge amount of methane leaking into the atmosphere that these countries and companies don't seem to be aware of. So, one of the main goals in tackling climate change is cutting our methane emissions. But if you don't really know how much you're actually emitting, you can't do a very good job of that.

  • Judy Woodruff: And then, if this isn't enough, William, there was yet another report from the National Oceanic and Atmospheric Administration out last week about sea level rise, and saying this is happening much faster than expected.

    Lay out some of that for us.

  • William Brangham: This report has got to be setting off alarm bells in coastal communities all over the world.

    The — NOAA said that, in the next 50 years, they expect, with fairly good confidence, that sea level rise will go up 10 to 12 inches. Now, that might not sound that much. It's about this much sea level rise. But just here in the U.S., there are major metropolitan areas, New York, Miami, Washington, New Orleans, parts of California, that are living right at sea level rise.

    And so 10 inches to a foot of sea level rise can have major impacts on infrastructure. Streets will be flooded much more often, not just on stormy days. Infrastructure will take a big hit.

    And so there's also a concern that that report, in and of itself, is alarming enough, but a worry that that might even be a lowball projection because of this ongoing question as to how much global warming is impacting the ice sheets in Greenland and in Antarctica.

    And in Antarctica specifically, there's a glacier there, the Thwaites Glacier, that is already showing signs of trouble. That glacier is holding two to three feet of potential sea level rise in its ice. So, if that were to go, we're talking about, as one researcher we spoke with saying, a global rewriting of the coastline all over the world.

  • Judy Woodruff: Well, it doesn't get any more sobering than all of this. Let's hope people are not only paying attention, but thinking about how we do something about all this, if we can.

    William Brangham reporting on these distressing reports.

    Thank you, William.

  • William Brangham: Thanks, Judy.

Fresh water cycles from ocean to air to clouds to rivers and back to the oceans.

This constant shuttling can give us the illusion of certainty. Fresh water will always come from the tap. Won’t it? Unfortunately, that’s not guaranteed.

Climate change is shifting where the water cycle deposits water on land, with drier areas becoming drier still, and wet areas becoming even wetter.

Our research published today in Nature has found the water cycle is changing faster than we had thought, based on changes in our oceans.

This concerning finding underlines the ever more pressing need to end the emissions of gases warming the atmosphere before the water cycle changes beyond recognition.

If this sounds serious, it is. Our ability to harness fresh water makes possible modern society.

It’s hard to track how much rain falls on our oceans. Shutterstock

The water cycle has already changed

 As the Earth warms up, the water cycle has begun to intensify in a “wet-gets-wetter-dry-gets-drier” pattern.

This means more and more freshwater is leaving dry regions of the planet and ending up in wet regions.

What might this look like? Weather, intensified. In relatively dry areas, more intense droughts, more often. In relative wet areas, more extreme storms and flooding.

Think of the megadrought afflicting America’s west, of the unprecedented floods in Germany, or of the increase in severe rainfall seen in cities like Mumbai.

This shift is already happening. In its landmark 2021 report, the UN’s Intergovernmental Panel on Climate Change (IPCC) drew on this growing body of research to conclude climate change was already causing long-term changes to the water cycle.

The changes we’re seeing are just the start. Over the next few decades, this water cycle intensification could make it much harder for people to get reliable supplies of fresh water across large areas of the planet.

Troublingly, while we know the water cycle is intensifying, we don’t fully know how much and how fast. That’s where the ocean comes into play.

How to use the ocean as a rain gauge

 The main reason it’s hard to directly measure changes to the water cycle is that we don’t have enough measurements of rainfall and evaporation over our planet.

On a practical level, it’s very hard to set up permanent rain gauges or evaporation pans on the 70% of our planet’s surface covered in water. Plus, when we assess change over the long term, we need measurements from decades ago.

The solution scientists have landed on is to use the ocean.

Many may not realise the ocean can be less or more salty depending on the region. For instance, the Atlantic is saltier than the Pacific on average. Why? Rain. When fresh water falls as rain on the ocean, it dilutes the sea water and makes it less salty. When water evaporates from the surface, the salt is left behind, increasing the salinity.

This means we can use the better-recorded changes in the ocean’s salinity as a kind of rain gauge to detect water cycle changes.

Earlier research used this method to track changes to the salinity at the ocean’s surface. This research suggested the water cycle is intensifying dramatically.

Unfortunately, the ocean does not stay still like a conventional rain gauge. Currents, waves and circular eddy currents keep the ocean’s waters in constant motion. This uncertainty has left a question mark over how exact the link between salinity and water cycle change actually is.

In response, we have developed new methods enabling us to precisely link changes in the ocean’s salinity to changes in the part of the water cycle moving fresh water from warmer to colder regions.

Our estimates indicate how the broader water cycle is changing in the atmosphere, over land and through our oceans.

What did we find in our new study?

 The fresh water equivalent of 123 times the waters of Sydney Harbour have shifted from the tropics to the cooler areas since 1970. That’s an estimated 46,000 to 77,000 cubic kilometres of water.

This is consistent with an intensification of the water cycle of up to 7%. That means up to 7% more rain in wetter areas and 7% less rain (or more evaporation) in dryer areas.

This is at the upper end of estimates established by several previous studies, which suggested an intensification closer to 2-4%.

Unfortunately, these findings suggest potentially disastrous changes to the water cycle may be approaching faster than previously thought.

What would the future be like with an altered water cycle?

 If our water cycle is getting more intense at a faster rate, that means stronger and more frequent extreme droughts and rainfall events.

Even if the world’s governments meet their target and keep global warming to a ceiling of 2℃, the IPCC predicts we would still endure extreme events an average of 14% stronger relative to a baseline period of 1850-1900.

Some people and ecosystems will be hit harder than others, as the IPCC report last year made clear.

For example, Mediterranean nations, south-west and south-east Australia, and central America will all become drier, while monsoon regions and the poles will become wetter (or snowier).

In dry areas hit by these water cycle changes, we can expect to see real threats to the viability of cities unless alternatives such as desalination are put in place.

What should we do? You already know the answer.

Decades of scientific research have shown the extremely clear relationship between greenhouse gas emissions and rising global temperatures, which in turn drives water cycle intensification.

This is yet another reason why we must move as quickly as humanly possible towards net-zero emissions to reduce the damage from climate change.

The changes to the water cycle we observed were largely due to older emissions, from the mid 20th century and earlier. We have increased our emissions dramatically since then.

What comes next is entirely up to us.

(The Guardian) Climate Change Is Intensifying Earth’s Water Cycle At Twice The Predicted Rate, Research Shows

The Guardian -

Rising temperatures pushing much more freshwater towards poles than climate models previously estimated

Rising global temperatures have shifted at least twice the amount of freshwater from warm regions towards the Earth’s poles than previously thought as the water cycle intensifies, according to new analysis.

Climate change has intensified the global water cycle by up to 7.4% – compared with previous modelling estimates of 2% to 4%, research published in the journal Nature suggests.

The water cycle describes the movement of water on Earth – it evaporates, rises into the atmosphere, cools and condenses into rain or snow and falls again to the surface.

“When we learn about the water cycle, traditionally we think of it as some unchanging process which is constantly filling and refilling our dams, our lakes, and our water sources,” the study’s lead author, Dr Taimoor Sohail of the University of New South Wales, said.

But scientists have long known that rising global temperatures are intensifying the global water cycle, with dry subtropical regions likely to get drier as freshwater moves towards wet regions.

Last August, the Intergovernmental Panel on Climate Change’s sixth assessment report concluded that climate change will cause long-term changes to the water cycle, resulting in stronger and more frequent droughts and extreme rainfall events.

Sohail said the volume of extra freshwater that had already been pushed to the poles as a result of an intensifying water cycle was far greater than previous climate models suggest.

“Those dire predictions that were laid out in the IPCC will potentially be even more intense,” he said.

The scientists estimate the volume of extra freshwater that shifted from warmer regions between 1970 and 2014 is between 46,000 and 77,000 cubic kms.

“We’re seeing higher water cycle intensification than we were expecting, and that means we need to move even more quickly towards a path of net zero emissions.”

The team used ocean salinity as a proxy for rainfall in their research.

“The ocean is actually more salty in some places and less salty in other places,” Sohail said.

“Where rain falls on the ocean, it tends to dilute the water so it becomes less saline … Where there is net evaporation, you end up getting salt left behind.”

The researchers had to account for the mixing of water due to ocean currents.

“We developed a new method that basically tracks … how the ocean is moving around with reference to this freshening or salinification,” Sohail said. “It’s kind of like a rain gauge that’s in constant motion.”

Dr Richard Matear, a chief research scientist in the CSIRO Climate Science Centre, who was not involved in the research, said the study suggested existing climate modelling has underestimated the potential impacts of climate change on the water cycle.

“There’s been a dramatic uplift in our ability to monitor the ocean,” he said.

“Observational datasets [like those used in the study] are really ripe for revisiting how global warming is changing the climate system, and the implications it might have on important things like the hydrological cycle.”
