'Ringing Alarm Bells': Australia Near The Bottom Of The Heap For Climate Action

Fairfax - Peter Hannam

Australia ranks as one of the world's worst performing nations when it comes to climate action, with only South Korea, Iran and Saudi Arabia faring worse among 56 countries scrutinised by 300 international analysts.
The annual Climate Change Performance Index, led by Germanwatch and other groups, listed Australia as "very low-performing" for its greenhouse gas emissions, energy use and climate policy. It scored a "low' rating for renewable energy.

Trees in Australian cities threatened by climate change
Research from the University of Melbourne has found that street trees and urban forests are facing a grave threat if emissions keep rising.

The results were released as talks in Bonn, Germany, aimed at shoring up support for the 2015 Paris climate accord enter their final few days.
As in the past three years, Australia has foundered near the bottom of the major tables, prompting the commentators to call on the Turnbull government to "sufficiently implement credible policies" to meet its Paris targets.
Environment and Energy Minister Josh Frydenberg, now in Germany, earlier this week declared Australia remains committed to its pledge to slice 2005-level emissions by 26-28 per cent by 2030.
Kelly O'Shanassy, chief executive of the Australian Conservation Foundation, said Australia had the highest per capita greenhouse gas emissions of those assessed, and was also one of the world's largest exporters of fossil fuels.
"Australia's continued failure to put in place a robust and comprehensive national plan to cut pollution is raising alarm bells around the world," Ms O'Shanassy said, noting emissions have been increasing since 2013.
"This is a national embarrassment for a wealthy nation with so much at risk from climate change and such abundant sun and wind that could be harvested for clean energy," she said.

Sweden was the top-ranked nation, marked highly for its efforts to boost low-carbon sources of electricity and its increasing forest cover.
The US was among the big movers in the ranking, sliding from 35th two years ago to just one slot above Australia this year.
It got marked down for its declaration to exit the Paris agreement – a move that left it isolated after Syria – the last nation holding out – recently signed up to the accord.

Climate Change Will Determine Humanity's Destiny, Says Angela Merkel

The Guardian - 

German chancellor, UN secretary general, Emmanuel Macron and others urge world’s leaders to succeed in their negotiations in Bonn

“Climate change is an issue determining our destiny as mankind – it will determine the wellbeing of all of us,” the German chancellor, Angela Merkel, has told the world’s nations gathered at a climate summit.
The delegates heard a series of strong political messages on Wednesday, urging them to use the final two days of the summit to complete important work on putting the landmark 2015 Paris deal into action. Without this, the world faces a devastating 3C or more of global warming.
The UN secretary general, António Guterres, told the conference in Bonn of his visit to the Caribbean after this year’s hurricanes.
“The catastrophic damage of climate change is upon us and when the frontline is devastated, the whole army is lost” he said, railing against the $825bn invested in fossil fuels in 2016. “We must stop making bets on an unsustainable future.”
The French president, Emmanuel Macron, who has been among the most vocal critics of Donald Trump’s decision to pull the US out of the Paris deal, got the loudest applause when he committed France and European partners to filling the funding gap for the UN’s climate science panel, left by the US withdrawal. “They will not miss a single euro,” he said.
Macron also emphasised the global importance of tackling global warming, saying: “The fight against climate change is by far the most significant struggle of our times.” He also addressed the issue that underpins most disputes at the global negotiations: the responsibility of rich nations that caused climate change to pay for the solution and compensate for the damage: “Climate change adds further injustice to an already unfair world.”
President Ali Bongo Ondimba of Gabon, representing African nations, said the need for faster action was urgent: “The fire is right under our feet. That is why I am expressing the extreme concern of Africa in light of the increase of disasters related to climate change. Africa suffers the loss and damage on a daily basis.”
“It is now time for the developed countries to live up to their responsibilities,” said Baron Waqa, president of Nauru and representing small island states. “Lack of resources is the problem.”
The talks in Bonn have progressed reasonably smoothly, without the drama and walkouts of previous summits. But one issue has flared up – whether rich nations are doing enough before 2020 to cut their emissions and to help poorer nations cope with the impacts of global warming.
It has been forced to the top of the agenda by the devastating floods and hurricanes seen around the world this year – as well as the meeting being run by the vulnerable island nation of Fiji. Negotiators agreed a deal on this on Wednesday, involving new stock takes of action in 2018 and 2019 and on progress towards the $100bn a year in climate funding that rich nations have promised to deliver by 2020.
The divisive issue of “loss and damage” – compensation for poor nations for the climate change damage – has been defused for now, with an expert meeting to address concerns next year. Progress has been made in drawing up the draft rules for implementing the Paris agreement, an essential step ahead of agreeing them in 2018.
Merkel, Guterres and Macron were almost upstaged by the first speech of the high-level session, given by 12-year-old Timoci Naulusala from Fiji, without any hint of nerves. Referring to the impact of Cyclone Winston in 2016, he said: “My home, my school, sources of food, money, water, were totally destroyed. My once beautiful village, which I called home, is a barren waste. Climate change is real, not a dream.”
Frank Bainimarama, Fiji’s prime minister and president of the summit, said: “We are not simply negotiating words on a page, but we are representing all our people and the places they call home.”
Merkel, who as an environment minister chaired the first climate summit 23 years ago, has been under pressure this week to phase out Germany’s large coal-fired power stations, which are likely to bust Germany’s climate targets.
“We still use a lot of coal, particularly lignite,” she said, acknowledging the issue is controversial, but she said jobs had to be taken into account too. She added that progress was expected in the next few days as she settles the terms of a new governing coalition with the Green and Liberal parties.
However, Prof John Schellnhuber, at the Potsdam Institute for Climate Impact Research in Germany, and who has advised both Merkel and the pope, said the 20,000 German jobs in coal would be lost to mechanisation in any case, and were a small number compared to the 600,000 created in the wider economy each year.
Macron set out unusual detail for a head of state in his speech, saying France would close all its coal power plants by 2021 and would ban all new exploration for fossil fuel in its territories. He also said France would fund interconnectors and energy storage technology to spread renewable energy around Europe and work to push the cost of CO2 emissions to €30 a tonne, which would end the viability coal and drive out gas.

As U.S. Sheds Role As Climate Change Leader, Who Will Fill The Void?

New York Times - Lisa Friedman

BONN, Germany — When President Trump announced in June that the United States would withdraw from the Paris agreement, America officially ceded its global leadership on climate change.
The retreat had actually begun months earlier, when climate change disappeared from most government websites and vanished from America’s domestic and international agendas.
No longer would the United States federal government address climate change at home or raise global warming with ministers and heads of state, as former President Barack Obama and his cabinet routinely did.
It was a dramatic shift, and it was meant to be.
“I was elected to represent the citizens of Pittsburgh, not Paris,” Mr. Trump said in repudiating the accord. “The Paris climate accord is simply the latest example of Washington entering into an agreement that disadvantages the United States to the exclusive benefit of other countries.”
Since then, others have taken up the climate leadership role. In Europe, Chancellor Angela Merkel of Germany and President Emmanuel Macron of France have vowed that the Paris agreement will flourish without the United States. President Xi Jinping of China and the Canadian prime minister, Justin Trudeau, are promoting their countries as climate change champions.
The United Nations secretary general, António Guterres, has pulled nations together to demand deeper emissions cuts. And American governors, mayors and business leaders have forged their own coalition, even taking over the United States pavilion at United Nations climate talks in Bonn, Germany, this week.
Political analysts say it’s not clear whether any of them can replace the United States and the immense diplomatic machinery it commands when engaged on an issue. Here’s a look at some of the strengths those leaders bring and the challenges they face.

1. Xi Jinping
President Xi Jinping didn’t mention Mr. Trump by name at the opening of the Communist Party Congress last month, but his meaning was clear when he declared that China had taken a “driving seat in international cooperation to respond to climate change.” He also criticized countries that “retreat into self-isolation.”
Many political analysts say China has indeed moved dramatically on climate change, both to meet its own pledge under the Paris accord to cap carbon emissions by 2030, and to start the world’s largest carbon market and swiftly expand the use of electric cars. In recent months, China has hosted ministerial-level meetings on clean energy and joined Canada and the European Union to lead discussions on climate.
Robert N. Stavins, the director of the environmental economics program at Harvard University who was in China recently to discuss climate change, said he had seen a dramatic shift in tenor among Chinese officials. “Having been engaged very, very closely on climate change with the Obama administration as a co-leader, China appears quite content to move from co-leadership to sole leadership,” he said.
Yet skepticism abounds. While the country is ahead of its Paris target, China still burns more coal than any other country. It also remains to be seen how eager the country will be to allow greater transparency of its own carbon reduction efforts, and many fear it will revert to old demands that it and other developing countries be treated with softer rules.

2. Justin Trudeau
For many years Canada was considered a laggard on climate change, leaving the Kyoto Protocol and rarely making an impression at United Nations negotiations.
That all changed with Prime Minister Justin Trudeau, who cozied up to panda bears and declared “Canada is back” at the Paris global warming talks in 2015. Mr. Trudeau said he was “deeply disappointed” in the United States’ decision to withdraw from the Paris deal, declaring “Canada is unwavering in our commitment to fight climate change.”
Since then, he has made good on much of that goal — doubling his country’s contribution to the United Nations science body and sliding into America’s place in some international arenas. In September, for example, Canada hosted a meeting of the world’s largest economies to discuss climate change. American officials in the George W. Bush administration had created that gathering, originally known as the Major Economies Forum, and it continued under Mr. Obama. The Trump administration essentially abandoned it this year.
“If the U.S. is going to step back, we’re going to step up,” Canada’s environment minister, Catherine McKenna, said.
But the country is still struggling to deliver meaningful climate change policy at home, and Mr. Trudeau in recent months has approved bitumen pipelines and liquid natural gas projects. Activists in Canada say if Mr. Trudeau wants to be a true leader, he’ll have to reject new fossil fuel infrastructure — something that will be a steep and perhaps unmeetable challenge.

3. State and local U.S. leaders
Perhaps no group has made a bigger splash on the world stage this year than the coalition of United States governors, mayors and businesses who call themselves the We Are Still In coalition. Informally led by Gov. Jerry Brown of California; Michael Bloomberg, the former mayor of New York, and Gov. Jay Inslee of Washington, the group has vowed to uphold the Paris agreement and move ahead with policies to fight climate change.
When the Trump administration opted not to have a United States pavilion at the Bonn climate talks to highlight American efforts on climate change, Mr. Bloomberg and others agreed to pay for it. Now the American pavilion is hosting a sort of shadow delegation of local leaders who say they are representing a different face of government. “I feel very strongly America should be represented there,” Mr. Bloomberg said.
Yet without participation from more states, particularly those that are fossil-fuel heavy, the United States as a whole will still fall short of the Paris pledge, several analyses have found.

4. Angela Merkel & Emmanuel Macron
The Obama administration gets a lot of credit for helping to forge the Paris Agreement, but in reality it was Europe that insisted on the accord in the first place. Since Mr. Trump’s withdrawal announcement, European leaders have lost no chance to reassert themselves as the guardians of global climate change ambition.
Mr. Macron in particular has continued to champion the agreement hammered out in his nation’s capital. He has invited American scientists who work on climate change to move to France, and pressed Mr. Trump several times to remain in the deal. In December, France will host a celebration of the Paris Agreement, to which the United States has not yet been invited. Ms. Merkel put climate change at the center of a Group of 20 summit of the world’s largest economies in Hamburg, Germany, this year.
It’s not clear how much those leaders’ efforts will shift United States policy. As Frank V. Maisano, a partner at the law firm Bracewell who represents energy clients, said recently, “Trump’s supporters don’t care that Macron is yelling at him. They like that.”

5. António Gutteres, U.N. secretary general
Mr. Gutteres stepped into his new role in January, and those who work with him say the former prime minister of Portugal jumped in with both feet. Mr. Guterres made sure climate change was highlighted during the United Nations General Assembly, meeting with former Vice President Al Gore and Governor Brown of California to discuss ways the United Nations can promote solutions. He also opened a special session to discuss climate change and its impact on small islands after several devastating hurricanes battered the Caribbean.
Robert C. Orr, the dean of the University of Maryland’s School of Public Policy and a special adviser to Mr. Guterres on climate change, said the United Nations leader was “putting his own stamp” on climate change by hosting a major summit at United Nations headquarters in New York in 2018.

Pacific Island Nations Urge World Leaders To Act As Islands Expected To Sink

NEWS.com.au - Matt Young

AUSTRALIA’S tropical island neighbours may exist today, but their leaders have urged us to help them from sinking.

How climate change will affect us.

A LARGE swath of Pacific Island nations are slowly being eaten away until residents will be forced to evacuate and the islands eventually sink into the sea — and it’s coming sooner than we think.
This modern-day Atlantis is thanks to sea levels across small island nations that have seen a dramatic rise over the past few decades, a rate of up to 3-4 times larger than the global average. Tuvalu, in the western Pacific Ocean, will reportedly be uninhabitable by 2050, while its island neighbour Kiribati, is expected to be fully submerged by 2100.
The Maldives, which has the lowest elevation in the world and a population of 427,000, may also have sunk by the end of the century.
It has led experts — including Professor Tim Flannery, climate change expert and Professor at La Trobe University — to believe we are “on a trajectory that will see those nations compromised”.
Five reef islands in the Solomon Islands have already been lost forever while a further six have been completely eroded. Last year, the island of Nuatambu had already lost half of its habitable area.
Professor Flannery told news.com.au The Maldives, Kiribati, Marshall Islands, Tokelau and Tuvalu were most at risk.
“It’s very much on their minds, they’re trying to work out how to deal with it,” Mr Flannery told news.com.au.



Scientists are convinced more and more of these tiny islands at risk of sinking into the sea in the next 30 years and Pacific Island leaders have gathered to urge its neighbours, including Australia, to take action to save their dwindling nations.
“There only remains a few years before we exceed carbon dioxide levels that will make temperature rise to levels that will see many parts of the Pacific disappear,” the president of Nauru, Baron Waqa, said during a meeting with Pope Francis at climate talks in Germany this month.
“The president is right, it’s very concerning times, particularly if you live in a small island nation,” Mr Flannery said.
Mr Flannery said the threat of sinking islands was real and a “widespread phenomenon” affecting low lying islands and beaches — and it seems the locals agree.
“There is overwhelming evidence that if we do not wake up now and act, we will hasten the calamities that await us and threaten our future survival and existence,” read an article in Fiji’s Sun Online.
“Those, who live in coastal settlements in Fiji, threatened by the encroaching sea, know. Those, whose plantations have been destroyed by sea water, know. Those, who have been relocated from their ancestral site because it is no longer safe to live there, know. Those, whose homes have been destroyed, know.
“In a nutshell, we need to adapt to the rapidly changing conditions. Otherwise, we and our posterity face a grim future.”

The dotted lines indicate the coast lines in 1984 while the solid line represents where the coast line of the islands were as of 2004. Source:AP
Some scientists worry for years that many of the tiny, low-lying islands throughout the South Pacific will eventually disappear under rising sea levels. Source:AP
Rising sea levels are considered an “existential threat” to the inhabitants of these islands and combined with melting glaciers, some anxious nations are already planning their escape.
In 2014, Kiribati, an island republic in the Central Pacific, purchased land 2000 kilometres away in Fiji, as rising tides continue to besiege the tiny nation.
“I carry a huge burden and responsibility,” Enele Sopoaga, the prime minister of Tuvalu, 965 kilometres north of Fiji, told a climate summit in 2015.
“It keeps me awake at night. Will we survive? Or will we disappear under the sea?”
It comes as New Zealand ponders becoming the first nation in the world to create a new visa category for Pacific Islanders based on island displacement.



For many island nations like Kiribati, it comes as a welcome proposal. Coastal erosion and freshwater contamination have already altered the lives of Kiribati’s 110,000 citizens and the future for the island looks grim.
“It’s hard to say how this will unfold but many of those nations are already making agreements to deal with the problem as it develops,” Mr Flannery said.
“Things are happening, we hope it doesn’t unravel so quickly that it will cause a big crisis but people are aware of it and they are adapting.
Mr Flannery explained that not only are the islands at threat of disappearing into the ocean, but residents were threatened with loss of freshwater and agriculture before the cataclysmic event.
“As sea water rises it starts to penetrate the freshwater on the land, that’s the most immediate threat for a lot of the islands,” Mr Flannery said.
“Beach and coastal erosion and flooding is another threat. With these two factors it’s entirely possible within the next 30 years some islands could be rendered uninhabitable.”



While Professor Flannery said it was impossible to predict the future with 100 per cent accuracy, he said it was likely we would see evacuations of various Pacific Islands over the next three decades.
“After all there’s already been a few very small islands that people have left and climate impact has been one of the factors. It’s probable that it will happen again.
While Australia has committed a $300 million climate change package for the Pacific, experts say it’s not enough, and are demanding a moratorium on coal mines to stop the threat of carbon emissions.
Meanwhile, though Australia says it is on track to meet its Paris Agreement commitment to reduce emissions, it hasn’t reassured Pacific leaders who pointed out approximately two-thirds of the coal made in Australia will be sent predominantly to India.
“We should be doing more to help those nations,” Mr Flannery said, citing the end of coal mining would be the “easiest fix”.

Though it’s not all doom and gloom. National Geographic reports some island have flourished in the past decade, with some even growing in size.
“Some islands grew by as much as 5.6 hectares in a single decade, and Tuvalu’s main atoll, Funafuti — 33 islands distributed around the rim of a large lagoon — has gained 32 hectares of land during the past 115 years,” it read.
“The islands are going to fight back as the environment changes, and adjust themselves to new equilibriums. But there may come a point when they can no longer do that, and we don’t know when that point will be reached. The biggest fear island people have is not knowing what will happen beyond that point.”

Climate Scientists Warn Time Is Running Out To Prevent Global Environmental Collapse

ABC AM - Michael Edwards

Time is running out to prevent a global environmental collapse — that's the stark warning 15,364 of the world's leading climate scientists have sent out.
The paper depicts a bleak future world ravaged by climate change. (Reuters: Jason Lee)

Key points:
  • 15,364 scientists from 180 countries out their names to the BioScience journal article
  • Paper called for population growth to be limited, and governments to stop only focusing on economic growth
  • However, scientists said it was not too late for governments to take action to prevent it
Scientists from 180 countries, many in the developing world, put their names to the journal article published today in Bioscience, which also predicted temperature rises and unpredictable weather patterns that would cause widespread misery.
But the paper also noted it was not too late for governments to do something about it.
The number is believed to be the largest group of scientists to have ever put their names to a research paper focused on climate change.
One of the key authors of the paper, Bill Laurance, a research professor at James Cook University in Queensland, said this was the first time he had ever seen such a letter get sent out.
The paper focused on a number of issues, including the depletion of oceans, deforestation, endangered species and extinct species numbers, fresh water pollution and urban liveability.
"All kinds of instances of liveability of the planet," he said.
"It's far more than just climate change, although that's certainly a critical part."
The paper has depicted a bleak future world ravaged by climate change, a world characterised by human misery.
It called for population growth to be limited and for governments to stop focusing solely on economic growth.
Professor Laurance said too many governments were still thinking short-term, citing Australia as an example, who he said had moved "backwards quite a lot in the last five to 10 years".
"For instance, Australia jettisoned the carbon tax, that was probably one of the most progressive things — it provided stability for the investment market, it provided incentives for alternative energy schemes and green energy sources, which are very important," he said.
"We're not going to get rid of coal overnight, but it is the dirtiest of all the fossil fuels and it is the one that contributes the most to global warming."

Global C02 emissions on the rise
The papers release coincided with new data showing Global CO2 emissions had risen for the first time in three years.
The Global Carbon Project collated the figures and blamed the increase on a growth in coal-fired electricity generation, as well as Chinese oil and gas consumption.
Local carbon emissions accounted for some of the rise, and scientists such as Frank Jotzo, from the Crawford School of Public Policy at the Australian National University, expressed concern Australia would not make its targets under the Paris Agreement.
"The outlook for 2017 is once again for no decline or perhaps more growth in greenhouse emissions — we're not seeing the kind of change that we'll need to see in order to meet the Paris commitments," Professor Jotzo said.

How To Save Humanity: 15,000 Scientists Urge Action Before 'Vast Human Misery' Takes Over

Newsweek - 

More than 15,000 scientists signed a warning letter to humanity. Its namesake? "A Second Notice." These experts are warning humanity for the second time against catastrophic biodiversity loss and widespread misery for humans, in a cautionary message for humans to make major changes.
The open letter, signed by 15,364 scientists from 184 countries, was published on Monday in BioScience. The massive group of scientists, led by William J. Ripple of Oregon State University, is pleading for humans to cut greenhouse gas emissions, phase out fossil fuels, reduce deforestation, and reverse the trend of collapsing biodiversity.
“Soon it will be too late to shift course away from our failing trajectory, and time is running out,” the authors concluded. “We must recognize, in our day-to-day lives and in our governing institutions, that Earth with all its life is our only home.”

It is the 25th anniversary since thousands of scientists signed a letter warning humanity back in 1992 in the “World Scientists’ Warning to Humanity.” On Monday, scientists are saying humanity has mostly failed at solving the problems that will be likely to lead to “vast human misery,” according to the first letter.
Since 1960, freshwater resources and vertebrate species have decreased by around 25 percent. Marine dead zones have skyrocketed by three-quarters. Carbon dioxide emissions have increased by 62 percent since 1960. The human population has increased by 35 percent and livestock by 20 percent.
“Moreover,” the authors write, “we have unleashed a mass extinction event, the sixth in roughly 540 million years, wherein many current life forms could be annihilated or at least committed to extinction by the end of this century.”

With surrounding sea levels rising, Kiribati President Anote Tong has predicted his country will likely become uninhabitable in 30-60 years because of inundation and contamination of its freshwater supplies.

The one shining light is the decrease of ozone-depleting chemicals by 68 percent. Earlier this month, the ozone hole was the smallest measured since 1988 (though still 2.5 times the size of the U.S.).
“The rapid global decline in ozone-depleting substances shows that we can make positive change when we act decisively,” they wrote. “We have also made advancements in reducing extreme poverty and hungry.” Other global successes include: decline in fertility rates, decline in deforestation, and rapid growth in the renewable-energy sector, all of which are happening in certain regions.
Within the doom-and-gloom disastrous future that scientists have predicted in their research, they offered several solutions. Though neither easy nor simple, they could reverse or at least curb humanity's current trajectory.
One solution, likely the most obvious: Phase out fossil fuels and increase green technologies and renewable energy. Plus, divest from fossil fuels altogether. Divestment—which refers to the ending of monetary investments of fossil fuels—would “encourage positive environmental change.”

Reuters 
Eating more plant-based foods would also curb the impending doom scientists predict, as well as reducing food waste overall. How to do that, they wrote, is through education and better infrastructure.
The letter urges us all to prioritize reserves for the world’s land, marine, freshwater, and aerial habitats—particularly those that are well-funded and well-managed. Maintaining nature’s “ecosystem services” by ending the conversion of forests, grasslands, and other native habitats was another recommendation. Ecosystem services are services that humans can benefit from by letting nature function normally. Those two recommendations above relate to three other recommendations: restoring native plant communities, rewilding regions with native species, and implementing adequate policy to end the poaching crisis.

Reproductive healthcare also made its way into the list of recommendations. Increasing education and voluntary family-planning services—especially where those resources are lacking—could reduce fertility rates. The human population has increased by 35 percent since 1992, the letter said, which adds further stress on Earth’s resources. They advise to estimate a scientifically defensible and sustainable population size for the long term.
The economic structure should address wealth inequalities in order to ensure that prices, taxation, and incentive systems take into account the cost of consumption patterns on the environment. General appreciation of nature, and an increase in nature education for children could help, too.
They ended with a positive message, writing: “We can make great progress for the sake of humanity and the planet on which we depend.”

Thousands Of Scientists Issue Bleak ‘Second Notice’ To Humanity

Washington Post - Sarah Kaplan

Planet Earth (NASA)
In late 1992, 1,700 scientists from around the world issued a dire “warning to humanity.” They said humans had pushed Earth's ecosystems to their breaking point and were well on the way to ruining the planet. The letter listed environmental impacts like they were biblical plagues — stratospheric ozone depletion, air and water pollution, the collapse of fisheries and loss of soil productivity, deforestation, species loss and  catastrophic global climate change caused by the burning of fossil fuels.
“If not checked,” wrote the scientists, led by particle physicist and Union of Concerned Scientists co-founder Henry Kendall, “many of our current practices put at serious risk the future that we wish for human society and the plant and animal kingdoms, and may so alter the living world that it will be unable to sustain life in the manner that we know.”
But things were only going to get worse.
To mark the letter's 25th anniversary, researchers have issued a bracing follow-up. In a communique published Monday in the journal BioScience, more than 15,000 scientists from 184 countries assess the world's latest responses to various environmental threats. Once again, they find us sorely wanting.
“Humanity has failed to make sufficient progress in generally solving these foreseen environmental challenges, and alarmingly, most of them are getting far worse,” they write.
This letter, spearheaded by Oregon State University ecologist William Ripple, serves as a “second notice,” the authors say: “Soon it will be too late to shift course away from our failing trajectory.”
Global climate change sits atop the new letter's list of planetary threats. Global average temperatures have risen by more than half a degree Celsius since 1992, and annual carbon dioxide emissions have increased by 62 percent.
But it's far from the only problem people face. Access to fresh water has declined, as has the amount of forestland and the number of wild-caught fish (a marker of the health of global fisheries). The number of ocean dead zones has increased. The human population grew by a whopping 2 billion, while the populations of all other mammals, reptiles, amphibians and fish have declined by nearly 30 percent.
The lone bright spot exists way up in the stratosphere, where the hole in the planet's protective ozone layer has shrunk to its smallest size since 1988. Scientists credit that progress to the phasing out of chlorofluorocarbons — chemicals once used in refrigerators, air conditioners and aerosol cans that trigger reactions in the atmosphere to break down ozone.
“The rapid global decline in ozone depleting substances shows that we can make positive change when we act decisively,” the letter says.
The authors offer 13 suggestions for reining in our impact on the planet, including establishing nature reserves, reducing food waste, developing green technologies and establishing economic incentives to  shift patterns of consumption.
To this end, Ripple and his colleagues have formed a new organization, the Alliance of World Scientists, aimed at providing a science-based perspective on issues affecting the well-being of people and the planet.
“Scientists are in the business of analyzing data and looking at the long-term consequences,” Ripple said in a release. “Those who signed this second warning aren't just raising a false alarm. They are acknowledging the obvious signs that we are heading down an unsustainable path. We are hoping that our paper will ignite a widespread public debate about the global environment and climate.”
