Children born today will face climate extremes on a scale never seen before with the poorest bearing the brunt of the crisis, scientists warn.

In an analysis of human exposure to climate change extremes — such as heatwaves, floods, droughts, wildfires, cyclones and crop failures — researchers found that children born in 2020 are two to seven times more likely to face one-in-10,000 year events than those who were born in 1960. 

And that's if warming continues under current policies to reach 4.9 degrees Fahrenheit (2.7 degrees Celsius) by 2100.

If the world warms even faster, reaching 6.5 F (3.5 C) by 2100, 92% of today's 5-year-olds will experience deadly heatwaves, 29% crop failures and 14% floods at some point in their lives.

In comparison, the researchers found 16% of those born in 1960 experienced extreme heatwaves in their lifetimes. The researchers published their findings today (May 7) in the journal Nature.

"By stabilizing our climate around 1.5 C [2.7 F] above pre-industrial temperatures, about half of today's young people will be exposed to an unprecedented number of heatwaves in their lifetime. 

Under a 3.5 C [6.5 F] scenario, over 90% will endure such exposure throughout their lives," study lead author Luke Grant, a physical scientist at the Canadian Centre for Climate Modeling and Analysis, said in a statement.

"The same picture emerges for other climate extremes examined, though with slightly lower affected fractions of the population. Yet the same unfair generational differences in unprecedented exposure is observed," he added.

Eco-anxiety is rife among children, with nearly 4 in 5 children aged under 12 worried about climate change, according to a YouGov poll commissioned by Greenpeace.

The effects of climate breakdown, and the human suffering it causes, are already evident — unprecedented heatwaves, storms, droughts, floods, extinctions and wildfires are taking place around the world.

But quantifying the hardships that changes to Earth's complex climactic systems will foist on future generations remains difficult. 

To arrive at a rough picture, the researchers behind the new study combed through demographic data for each location on the planet, combining population projections and life expectancies with climate model projections for three emissions scenarios.

This enabled the researchers to arrive at rough estimates for the number of people in each generation who will experience unprecedented climate events. 

And the results they arrived at were stark — 52% of children born in 2020 face unprecedented heat exposure compared to 16% of those born in 1960 under the most limited global warming scenario of 2.7 F (1.5°C) by 2100, rising to 92% if warming reaches 6.5 F (3.5 °C).

Exposures to crop failures, wildfires, droughts, floods and cyclones also rose significantly. For example, in a 6.5 F (3.5 °C) pathway 29% of those born in 2020 will face unprecedented lifetime exposure to crop failures, with the risk expanding for those around the United States, South America, Sub-Saharan Africa and East Asia.

And those most socioeconomically vulnerable, especially children born around the tropics, are set to be the most strongly impacted. 

Under current policies, 92% of today’s five year olds born into low-income groups are exposed to lifetime risk compared to 79% of those from wealthier backgrounds.

"Living an unprecedented life means that without climate change, one would have less than a 1-in-10,000 chance of experiencing that many climate extremes across one's lifetime," Grant said. 

"This is a stringent threshold that identifies populations facing climate extremes far beyond what could be expected without man-made climate change."

The researchers note that their study is far from complete — they didn’t model climate change’s impacts on fertility, mortality or migration. 

This means that the effects of climate change in sparking mass migrations and resource wars were not accounted for in their analysis, and neither were the various tipping points our warming world is edging closer toward.

In an accompanying News & Views article, Rosanna Gualdi and Raya Muttarak, from the Department of Statistical Sciences at the University of Bologna, Italy, wrote that the findings "reveal an alarming intergenerational gap" in exposure to climate extremes.

"If greenhouse gases continue to be emitted into the atmosphere at current rates, global warming will intensify and today's children will be exposed to increasingly frequent and severe climate-related hazards," they wrote.

"The actions taken today to reduce emissions are therefore crucial in shaping the climate future of current and coming generations. 

Given that the impacts of climate change and the transformations required to decarbonize society are not distributed equally, it is important to consider equity in the transition to net-zero emissions. 

This includes addressing the intergenerational inequality highlighted by Grant et al. Neglecting it jeopardizes the future of our children."

Australia’s Climate Reckoning: Food, Finance, and the Future - Lethal Heating Editor BDA

2025-05-10_3

🌏 Australia finds itself at a crossroads. It is a country that exports fossil fuels to the world, yet at home, it bears the brunt of a changing climate.

Scorched farmland, vanishing insurance, and rising seas are no longer warnings of the future, they're headlines of the present.

🔥 The Heat on the Land

2025-05-09_111In the vast wheat belts and sun-bleached cattle stations of regional Australia, climate change is burning through the bottom line. 

Since 2000, variable rainfall and extreme heat have slashed farm profits by more than 23%, according to the CSIRO

Farmers now battle not just the soil, but the sky itself: longer droughts, sudden floods, and brutal temperature spikes. 

Crops wilt. Livestock perish. 

Even the mighty Murray-Darling Basin, lifeline of inland agriculture, is buckling under the pressure.

🌊 Counting the Cost of Crisis

2025-05-09_22

Climate change isn't just an environmental threat, it's a financial one. 

Over the past decade, climate-related disasters have cost Australia over $35 billion, as reported by The Climate Council

Fires, floods, and cyclones now tear through cities and rural communities with alarming frequency. Lismore. Mallacoota. Cobargo. 

Towns that once thrived are now synonymous with crisis.

Thousands have lost homes, businesses, and livelihoods, and the emotional toll is incalculable.

🏠 The Insurance Retreat

2025-05-09_33

Insurance companies are quietly rewriting the map of livability in Australia. 

As floodwaters rise and bushfires rage, insurers are pulling out of vulnerable regions. 

The Actuaries Institute estimates that by 2030, one in every 25 homes could be uninsurable due to climate risk. 

Coastal homes once seen as dream real estate now carry the weight of future loss. 

Policies, if available at all, come with soaring premiums, pricing ordinary families out of protection.

☀️ The Sunburnt Nation's New Hope

2025-05-09_44

And yet, in this crucible of crisis, opportunity is taking root. 

Australia is blessed with some of the world's best solar and wind resources. 

The Clean Energy Council says more than 30% of homes now have rooftop solar. Entire regions like South Australia regularly operate on 100% renewable energy. 

The transition could create tens of thousands of clean energy jobs, generate billions in export income, and place Australia at the centre of the global green economy. 

Green hydrogen produced with renewable energy is being hailed as the country's next great export boom. 

Major projects are already underway in Queensland, Western Australia, and the Northern Territory.

🚨 A Nation at the Tipping Point

2025-05-10_4

What's at stake is more than beachfront property or economic performance. 

It's the integrity of an entire ecosystem: Australia's ancient biodiversity, its rural communities, its future prosperity. 

Scientists and environmental leaders agree: Australia must step up with stronger climate policy, both at home and on the global stage. 

Because the scars of a warming world are already here, and they are deepening.  

The question is no longer if Australia will act.

It's whether it will act fast enough.

Climate Change in Australia: A Nation on the Front Lines - Lethal Heating Editor BDA



Australia has always been a land of climatic extremes, but in recent decades, those extremes have sharpened. 

Fueled by climate change, the country now faces intensifying droughts, catastrophic bushfires, rising seas, and an alarming loss of biodiversity. 

Here's how the crisis is reshaping Australia—from its coastal cities to its coral reefs and wild bushlands:

Drought, Fire, and Flood: The New Normal

In Australia, weather has become more than unpredictable—it’s become volatile.

Longer dry spells are now common in the country’s southeast and southwest, the agricultural heartlands. 

Rainfall is becoming less reliable, and when it does arrive, it often comes in destructive bursts. 

These shifts are tied to the warming climate and are making multi-year droughts more frequent and intense.

Simultaneously, bushfire seasons are lengthening and becoming more ferocious. 

The 2019–2020 Black Summer fires scorched over 24 million hectares, destroyed thousands of homes, and blanketed cities in hazardous smoke. The Royal Commission directly linked the severity of these fires to climate change.

And then came the floods. In early 2022, record-breaking rainfall inundated large swaths of eastern Australia, leaving towns underwater and thousands displaced. These rapid swings—from drought to deluge—are a hallmark of a climate out of balance.

Rising Seas, Sinking Cities

Sea levels around Australia have already risen by about 25 centimeters since 1880. But that’s just the beginning.

According to the IPCC’s Sixth Assessment Report, Australian coastlines could see sea levels rise by up to one meter by 2100 under high-emission scenarios. 

Cities like Sydney, Melbourne, and Brisbane face an increased risk of coastal erosion, tidal flooding, and infrastructure collapse.

Even moderate sea-level rise threatens the Torres Strait Islands, where some communities are already retreating inland.

The Great Barrier Reef: A Dying Wonder

Nowhere is the ocean crisis more visible than on the Great Barrier Reef, the world’s largest coral system and a UNESCO World Heritage Site. 

But its status is slipping.

Marine heatwaves have triggered five mass coral bleaching events since 1998, with back-to-back events in 2016 and 2017 killing off roughly half the reef’s shallow water coral. 

Warmer seas weaken the reef’s resilience, and rising carbon dioxide levels are acidifying the water, undermining the corals’ ability to rebuild.

Without global emissions cuts, scientists warn the reef could be functionally dead by 2050.

Wildlife in Crisis

Australia’s flora and fauna are unique. They are also among the most threatened by climate change.

The Black Summer bushfires alone affected an estimated 3 billion animals. Koalas, already struggling from habitat loss, face even greater danger from drought and heat stress. 

The platypus, once common, is now disappearing from parts of its range. Birds, frogs, reptiles—even alpine marsupials—are shifting habitats or vanishing altogether.

Climate change acts as a “threat multiplier,” intensifying the effects of land clearing, invasive species, and disease. Once these ecosystems pass a certain threshold, recovery may be impossible.

A Call to Action

Australia is one of the world's largest exporters of fossil fuels, yet it also bears some of the most visible scars of a warming world. 

Scientists and environmental groups say that stronger climate policy—domestically and globally—is essential to limit the damage.

The stakes are clear. What’s at risk is not just biodiversity or beachfront property—it’s the stability of life across an entire continent.

Australia’s Climate Reckoning: Heatwaves, Policy Shifts, and a Tipping Point - Lethal Heating Editor BDA

Australia is no stranger to climate extremes. But 2025 has ushered in a new era—one defined not only by record-shattering heat, but by a reckoning over how to respond to a crisis unfolding in real time.

According to the Bureau of Meteorology, Australia has just recorded its hottest 12-month period on record, with national temperatures 1.61°C above average. 

Phys.org reports that the past year has been punctuated by catastrophic floods, intensified cyclones, and back-to-back coral bleaching events—many directly linked to this warming trend.

Nowhere is the crisis more visible than along South Australia’s coast, where marine life has washed ashore en masse—victims of a devastating algal bloom fuelled by warming seas and nutrient run-off. 

Sharks, rays, and bottom-dwelling fish are among the casualties. Marine scientists warn it could be the sign of an ecosystem on the brink.  

“It’s a dire warning,” says one expert.

🌿 A Political Mandate for Action

This environmental upheaval arrives amid a dramatic political shift. 

In a clear public endorsement of stronger climate action, Prime Minister Anthony Albanese’s Labor Party secured a resounding victory in the 2025 federal election. The party now faces the challenge of translating bold promises into real outcomes.

Labor has pledged 82% renewable electricity by 2030 and introduced the Net Zero Economy Authority to manage the transition. It also reformed the Safeguard Mechanism to limit industrial emissions.  

The Guardian writes that “Australia has backed a rapid shift to renewable energy.”

However, the opposition Coalition has proposed a controversial $120 billion nuclear energy plan that could add 2 billion tonnes of emissions while cutting $30 billion from existing renewables, prompting a wave of backlash from climate scientists and energy analysts alike.

ABC News reports the plan is under fire for undermining Australia’s climate targets.

🏛️ Local Governments Step Up

At the community level, councils are taking climate responsibility into their own hands. 

In Victoria’s Surf Coast Shire, officials are ending their carbon offset program to focus on direct action—electrifying council buildings and converting fleets to electric vehicles.  

The Herald Sun notes the council is still aiming for net-zero by 2030, excluding landfill emissions.

⏳ The Climate Clock Is Ticking

Despite progress, experts say Australia isn’t yet on track to meet its 2030 emissions targets. 

The Climate Change Authority stresses the urgency of cutting emissions across all sectors—transport, agriculture, and heavy industry.

At the federal level, the Albanese Government has expanded marine protections and introduced a long-anticipated Environment Protection Agency to enforce stronger environmental laws. See a full overview on Wikipedia’s Albanese Government page.

As global temperatures rise, Australia stands at a crossroads—either to lead the world in climate resilience or to become a case study in missed opportunity.

Australia’s Climate Crossroads: A Nation Rallies Behind Renewables Amid Record Heat - Lethal Heating Editor BDA

In May 2025, Australia arrived at a critical juncture in its long and complicated battle with climate change. After years of environmental inaction shadowed by fossil fuel influence, voters delivered a clear and resounding message at the ballot box: they want a cleaner, greener future — and they want it fast.

Prime Minister Anthony Albanese’s Labor government emerged from the 2025 federal election with an expanded mandate and a sharpened climate agenda. 

The platform? Rapid decarbonisation, 82% renewable energy by 2030, and net-zero emissions by 2050. In the eyes of many, this election wasn’t just about politics — it was a referendum on climate action.

"Australia has backed a rapid shift to renewable energy – and given Labor a chance on climate. How will it act?" - The Guardian

The Coalition opposition, led by Peter Dutton, had campaigned for a return to coal and gas, with a dash of nuclear. It failed to resonate. 

Australians, now regularly living through heatwaves, floods, and coastal erosion, showed little appetite for half-measures or nostalgic energy policy. 

Instead, climate-conscious voters turned out in force, with younger demographics particularly energised by the prospect of green innovation and environmental security.

“This was the climate election we were waiting for,” says Dr. Emily Hughes, a political ecologist at the University of Sydney. “Not just because of the promises made — but because of the public’s overwhelming rejection of delay.”

Backing up the public urgency is nature’s own relentless testimony. The past year was officially Australia’s hottest 12-month period on record, with the average temperature soaring to 1.61°C above the historical norm.

"Australia just experienced its hottest 12 months on record" - Phys.org

The impacts have been devastating and unmistakable. 

Mass coral bleaching events continue to ravage the Great Barrier Reef. 

Cyclones, once seasonal threats, are now creeping deeper into the calendar year. 

Inland, extreme heat has become routine, especially in vulnerable rural areas. 

And in urban centres like Sydney, which faces rapidly intensifying bushfire seasons and climate-driven housing stress, scientists warn that planning must evolve — or fail disastrously.

"Climate change is making Sydney more vulnerable to natural disasters" - Financial Times

The renewable energy sector is now urging the Albanese government to seize the political moment. 

Industry leaders are pushing for a formal 2035 emissions reduction target and a faster deployment of solar, wind, and storage infrastructure. 

They warn that without bold new policy tools — including carbon pricing, investment in green hydrogen, and grid modernisation — the 2030 and 2050 targets could become aspirational rather than achievable.

"Wind and solar industry urges Labor to embrace mandate for faster transition to 2030 target" - The Australian

Amidst all this, a haunting symbol of global accountability is taking shape on Tasmania’s remote west coast: “Earth’s Black Box.” 

This massive data vault, encased in steel and solar-powered, is being built to document the downfall — or survival — of human civilisation in the face of climate change. 

It will record scientific data, political decisions, and public discourse, capturing every milestone in the climate crisis for future generations, or potentially, post-collapse societies.

"‘Earth’s Black Box’ Will Record Our Climate Crisis for Future Generations" - LADbible

The message is clear: the world is watching. 

Australia, long a global climate laggard, now has both the political power and moral obligation to lead. 

Whether this latest election marks the beginning of a lasting transformation or another missed opportunity will depend on what the Albanese government does next — and how hard civil society pushes it to act.

The New Face of Climate Apathy: How the World Is Adjusting Too Quickly to Crisis - Lethal Heating Editor BDA

Lost winters, not just rising temperatures, shakes climate indifference. Image Credit USGS



In the eerie stillness of a snowless winter or the silence where ice skates once scraped across a frozen lake, a dangerous kind of numbness is setting in. It's not just the planet that’s warming—our sense of urgency is cooling.

Climate change, once a firebrand issue that stirred protest and pledges, is now slipping into the background noise for many. And according to a sobering new study published in Nature Human Behaviour, we may be adapting psychologically to the climate crisis just as quickly as the climate itself is deteriorating.

“People are adjusting to worsening environmental conditions, like multiple fire seasons per year, disturbingly fast,” says Rachit Dubey, lead researcher and an incoming UCLA communications professor. UCLA Newsroom

The Boiling Frog Phenomenon

Dubey likens this to the infamous “boiling frog” metaphor: throw a frog into boiling water and it jumps out; slowly heat the water and it stays put, unaware of its doom. Humans, it turns out, are the same. We normalize incremental shifts—a little more heat, a little less ice—until the climate we remember no longer exists.

The study’s solution? Ditch the temperature charts. Replace them with emotional, binary snapshots of what’s been lost. Instead of displaying rising temperatures, the researchers showed people whether local lakes froze in winter each year from 1940 to 2020. Participants rated the climate impact as 12% more severe with freeze/no-freeze data.

“It’s not just warmer winters; it’s the loss of ice hockey and white Christmases,” says co-author Grace Liu. “It’s not just hotter summers; it’s the dried-up swimming hole or cancelled soccer practice due to extreme heat.” Nature Human Behaviour study

When Personal Becomes Political

The experiment spanned both fictional towns and real-world locations like Lake George, NY and Grand Traverse Bay, MI—places where seasonal traditions define community identity. Participants shown the loss of these traditions responded with greater alarm than those fed scientific metrics.

And that’s the key: personal stories, not polar bears, drive public concern. As climate scientists and communicators scramble to break through the noise, the power of human-scale storytelling is becoming undeniable.

A New Tool for Urgency

Dubey points to the viral Show Your Stripes graphic, which compresses decades of temperature data into colourful bars that morph from cool blues to alarming reds. It’s not binary, but it’s visceral—and that makes all the difference.

Ed Hawkins’ Climate Stripes
The Next Fight: Fighting Numbness

The danger now is not disbelief—it’s detachment. And the antidote may lie not in more data, but better stories. “We thought worsening climate would naturally motivate people to act,” Dubey reflects. “Instead, we’re watching them emotionally adapt.”

As policymakers prepare for hotter summers and vanishing winters, this research offers a new frontier in climate communication. 

Forget the boiling frog. It’s time to show people the empty pond, the unplayed game, the quiet snowfall that never came.

Al Gore on climate and Trump – the whole speech

Pearls and Irritations

Al Gore

Readers may have seen mainstream media coverage of former US vice-president Al Gore's speech at San Francisco Climate Week on 21 April. We think it is worth reading in full.

Al Gore
Former US Vice President Al Gore is the founder and chairman of The Climate Reality Project, a nonprofit devoted to solving the climate crisis, a founding partner and chairman of Generation Investment Management, and a co-founder of Climate TRACE.
It is abundantly clear, after only three months and one day, that the new Trump administration is attempting to do everything it possibly can to try to halt the transition to a clean energy future and a deep reduction in the burning of fossil fuels. 

The climate crisis is a fossil fuel crisis, basically 80% of it.

Many of you here today have likely felt the chilling effect of the policies and the rhetoric coming from Washington, DC, and what the effect has been on businesses and investors and far beyond.

The Dow Jones, of course, today fell another thousand points, and since Donald Trump’s inauguration it’s gone down 6000 points.

But while the most visible impacts of what the new administration is doing may be in the market for stocks and bonds, that’s not the only thing that he has caused to crash.

The trust market has crashed.

The market for democracy has taken a major hit.

Hope is being arbitraged in the growing market for fear.

Truth has been devalued and confidence in US leadership around the world has plummeted.

We are facing a national emergency for our democracy and a global emergency for our climate system.

We have to deal with the democracy crisis in order to solve the climate crisis.

The scale and scope of the ongoing attacks on liberty are literally unprecedented. With that in mind, I want to note before I use what is not a precedent, I understand very well why it is wrong to compare Adolf Hitler’s Third Reich to any other movement. It was uniquely evil, full stop. I get it.

But there are important lessons from the history of that emergent evil, and here is one that I regard as essential. 

In the immediate aftermath of World War II, a small group of philosophers who had escaped Hitler’s murderous regime returned to Germany and performed a kind of moral autopsy on the Third Reich. 

The most famous of the so-called Frankfurt School of Philosophers was a man named Jurgen Habermas – best known, I would say. 

But it was Habermas’ mentor, Theodor Adorno, who wrote that the first step of that nation’s descent into Hell was, and I quote, “the conversion of all questions of truth into questions of power". 

He described how the Nazis, and I quote again, “attacked the very heart of the distinction between true and false".

The Trump administration is insisting on trying to create their own preferred version of reality. They say Ukraine attacked Russia instead of the other way around, and expect us to believe it! At home, they attack heroes who have defended our nation in war and against cyberattacks as traitors.

They say the climate crisis is a “hoax” invented by the Chinese to destroy American manufacturing.

They say coal is clean.

They say wind turbines cause cancer.

They say sea level rises just create more beachfront property.

Their allies in the oligarchic backlash to climate action argue that those who want to stop using the sky as an open sewer, for God’s sake, need to be more “realistic” and acquiesce to the huge increases in the burning of more and more fossil fuels (which is what they’re pushing), even though that is the principal cause of the climate crisis.

You may not be surprised to learn that this propagandistic notion of “climate realism” is one that the fossil fuel industry has peddled for years.

The CEO of the largest oil company in the world, Saudi Aramco, has said, “We should abandon the fantasy of phasing out oil and gas.”

His colleague, Exxon CEO Darren Woods, has claimed that “the world needs to get real. … The problem is not oil and gas. It’s emissions".

The American Petroleum Institute says that we need “a more realistic energy approach” – one that, you guessed it, includes buying and burning even more oil and gas.

So, allow me to put this question to all of you: What exactly is it that they want us to be realistic about?

Their twisted version of “realism” is colliding with the reality that humanity is now confronting.

The accumulated global warming pollution (because these molecules linger there on average about 100 years and it builds up over time), is trapping as much extra heat now every single day as would be released by the explosion of 750,000 first generation atomic bombs blowing up on the Earth every single day!

Is it realistic to let that continue?

Is it realistic to think that if we opt out of taking action to reduce greenhouse gas pollution, we’ll be able to just wish it away and continue with business as usual? Well, Mother Nature makes a pretty good case against that argument. Every night the TV news is like a nature walk through the Book of Revelation.

Is it realistic, for example, to continue stoking the risk of wildfire in California, after what has already happened to so many communities in Northern California? And just look at the devastation caused by the Los Angeles wildfires in January.

Is it realistic to tell homeowners around the world that the global housing market is expected to suffer a US$25 trillion loss in the next 25 years? Fifteen percent of all the residential housing stock in the world if we do not change what we’re doing? Is that realistic in their view?

Is it realistic to continue quietly accepting 8.7 million deaths every single year from breathing in the particulate co-pollution that also comes from the burning of fossil fuels? That is the number of people who are already being killed. 

According to health experts, it is, and I quote, “the leading contributor to the global disease burden". When you’re burning coal, oil and gas, it puts the heat trapping pollution up there and it puts the particulate and PM 2.5 pollution into the lungs of people downwind from where the facilities are burning the fossil fuels.

Is it realistic, in their view, for governments to manage a billion climate migrants crossing international borders in the remainder of this century? 

That’s how many the Lancet Commission estimates will be crossing borders in the decades to come, if we continue driving temperatures and humidity higher and making the physiologically unliveable regions of the world vastly larger by continuing to put 175 million tonnes of man-made heat-trapping pollution into that thin shell of the troposphere surrounding the planet. 

You know what that blue line looks like, that thin blue shell is blue because that’s where the oxygen is. And it’s so thin, if you could drive a car straight up in the air at highway speeds, you’d get to the top of that blue line in five to seven minutes.

That’s what we’re using as an open sewer. Is that realistic? I don’t think it is.

We’ve already seen, by the way, how populist authoritarian leaders have used migrants as scapegoats and have fanned the fires of xenophobia to fuel their own rise to power. And power-seeking is what this is all about. Our Constitution, written by our founders, is intended to protect us against a threat identical to Trump: someone who seeks power at all costs to get more power. 

Imagine what the demagogues would do as we continued toward a billion migrants crossing international borders. We could face a grave threat to our capacity for self-governance.

Is it “realistic” to continue inflicting the financial toll that the climate crisis is taking on the global economy? According to Deloitte, climate inaction will cost the economy US$178 trillion over the next half-century. And is it realistic to miss out on the economic opportunity that we could seize by going toward net zero? Over that same period, climate action would increase the size of the global economy by US$43 trillion.

A question with particular relevance in nearby Silicon Valley: is it realistic for the semiconductor industry to experience losses of up to 35% of annual revenues due to supply chain disruptions caused by the stronger and more severe cyclonic storms and supercell storms?

Is it realistic to continue with a system of financing that leaves the entire continent of Africa completely out? Right now, the entire continent of Africa, fastest-growing population in the world, has fewer solar panels installed than the single state of Florida in the US. 

That’s a disgrace in the make-up of our financial system. But Africa has three times as many oil and gas pipelines under construction, and preparing for construction to begin, than all of North America. It is ridiculous to allow this system to continue as it is. How is that realistic? Or fair? Or just?

Is it realistic for us, all of us here, to consign our children and grandchildren to what scientists warn us would be Hell on Earth in order to conserve the profits of the fossil fuel industry? The predictions of the scientists 50 years ago have turned out to be spot-on. 

Their predictions just a few decades ago have turned out to be exactly right. Should not that cause us to listen more carefully to what they’re warning us will happen if we do not sharply and quickly reduce the emissions from burning fossil fuels?

Is that unrealistic to listen to a proven source of advice?

This newfound so-called climate realism is nothing more than climate denial in disguise. It is an attempt to pretend there is no problem and to ignore the reality that is right in front of our faces.

What’s never present in any of this so-called “realism” is any credible challenge whatsoever to the conclusions of the Intergovernmental Panel on Climate Change, the IPCC. They never address that. They just wish it away and say, “Oh it’s unrealistic to actually do anything about it.”

I wish we could wish it away, but we cannot.

The harsh reality is that the fossil fuel industry has grown desperate for more capital. They’re seeing their two largest markets wither away: electricity generation, number one and transportation, number two. They’ve been losing their share of investment in the energy market to renewables and so they’re panicked.

That explains why they are so aggressively using their captive policymakers to block meaningful solutions. Of course, as you know, they’re much better at capturing politicians than they are at capturing emissions. They’ve grown very skillful at that.

They are the wealthiest and most powerful industry lobby in the history of the world. They make the East India Company look like a popcorn vendor. They are the effective global hegemon.

They have used their war chests and their legacy network of political and economic power to block any reductions of fossil fuel emissions – whether at the international conferences that we call the COPs, the Conference of Parties in the UN process, or at the global negotiations for a plastic treaty. They blocked anything there, too.

Why? They’re losing the first market of electricity generation because 93% of all the new electricity generation installed worldwide last year was solar and wind. They’re losing that market steadily. Use of EVs is rising dramatically. They say they’ve slowed down. Well, we just got the new figures – an 18% increase year-on-year here in the US. In many countries, it is much faster than that.

And so, their third market – they’re telling Wall Street that they’re going to make up all of the expected lost revenue in their first two markets by tripling the production of plastics over the next 35 years.

Well, we might have a word to say about that. Is that realistic? Because we’ve already found — the scientists say — that some seabirds are manifesting symptoms like Alzheimer’s disease from the plastic particles in their brains and they found that it crosses the blood-brain barrier in humans, and the amount has doubled just in the last decade.

Do we really want to continue that?

It’s crazy, but they are blocking action at both of these international forums and they’re blocking action in the deliberations of nation-states, even in states and provinces, and even at the local level. Anywhere in the world where there is an effort to pass legislation or regulations that reduces the burning of fossil fuels, they are there with their money, with their lobbyists, with their captive politicians, blocking it as best they can.

And the solution is what you’re doing here at Climate Week here in San Francisco. We have got to rise up and change this situation.

That’s also why they are ballyhooing ridiculously expensive and hilariously impractical technologies like building giant mechanical vacuuming machines to suck it back out of the atmosphere after they put it up there. Could that someday be a realistic part of the solution?

Perhaps, perhaps. But not now! Not even close.

They use it as a bright, shiny object to distract attention and say, “see this, see this, this could be so miraculous, we don’t have to stop burning fossil fuels at all! We can actually continue to increase the burning of fossil fuels because look at this bright, shiny object. We’ve got this vacuuming machine”.

Well, CO2 is 0.035% of the molecules in the air. You’re going to use an energy-intensive, ridiculous, expensive process to filter through the other 99.965% of the molecules? It’s absolutely preposterous.

In reality, the Sustainability Revolution is powering more and more of our global economy. It has the scale and impact of the Industrial Revolution and is moving at the pace of the Digital Revolution.

By the way, in Texas, which used to have a free market for energy, more than 90% of all their new electricity generation last year was solar and wind. And, you know, they’ve got captured politicians there. 

They’re pushing legislation in Texas to legally require any developers of solar and wind to spend time and money developing more oil and gas before they’re given permission to develop renewables.

That’s not realism, that’s pathetic.

That is a sign of desperation.

They don’t trust the free market. They’re just relying more and more on the politicians who will jump when they tell them to jump and ask how high when they tell them to jump again.

So, around the world, the market is transforming. Since the Paris Agreement, the cost of solar has dropped 76%. The cost of wind is down 66%. The cost of utility-scale batteries is down 87%.

In 2004, when Generation was founded, it took a full year for the world to install one gigawatt of solar power. Now it takes one day to install that.

And it’s not just renewables. We’re seeing the Sustainability Revolution rapidly take hold across the rest of the global economy from transportation, to regenerative agriculture, to circular manufacturing, and so much more.

So, as we gather here to kick off Climate Week and as we gather on the eve of Earth Day, we have to treat this moment as a call to action. So, I’m here not only to respond to the invitation for which I’m grateful… I’m here to recruit you.

Many of you are already working on this, but those of you who are not, I’m here to recruit you. We need you. This is the time and this is a break glass moment. This is an all hands on deck moment.

Now is the time to look at every aspect of your businesses, your investments, and your civic engagement to determine whether or not you can contribute even more to solving the climate crisis.

It’s easy to adopt our own versions of climate realism to say the challenge is too great. Some people worry about that. To say that our individual role is too small to have an impact. Some use that as an excuse: if the government won’t act, what can any of us do about it?

Well, just as the climate crisis does not recognise borders, it does not either recognise delineations between the duty of government and businesses and all significant participants in the global economy.

Climate change is already affecting your life and work and will more so through disrupted supply chains, increased liability, changes in consumer demand, and more.

This is a moment when we all have to mobilise to defend our country. And remember, the antidote to climate despair is climate action. It was in this city in the 1960s that Joan Baez first said that the antidote to despair is action. And we need to remember that now.

And during a time when people were tempted to despair in the struggle for civil rights in this country, Martin Luther King said something about overcoming the forces that try to discourage you and halt progress. He said this: “If you can’t fly, run. If you can’t run, walk. If you can’t walk, crawl. But by all means, keep moving.”

And that’s where we are.

Every one of the morally based movements in the past had periods when advocates felt despair. But when the central choice was revealed as a choice between right and wrong, then the outcome at a very deep level became foreordained.

Because of the way Pope Francis reminded us we have been created as God’s children.

We love our families.

We are devoted to our communities.

We have to protect our future.

And if you doubt for one moment ever that we as human beings have the capacity to muster sufficient political will to solve this crisis, just remember that political will is itself a renewable resource.
