200+ Global Scientists Urge Immediate Large-Scale Action to Limit Global Warming

The scientists point to a “rapidly shrinking” carbon budget to limit warming over the century to 1.5 degrees Celsius.

"MAX 1.5 degrees" is written on a banner held by a protester in front of the Brandenburg Gate in Berlin, Germany, on October 22, 2021.

As a global group of hundreds of scientists urged negotiators at COP26 to acknowledge the latest climate science by committing to “immediate, strong, rapid, sustained, and large-scale actions,” the head of the United Nations expressed pessimism Thursday that the talks will end with an agreement limiting warming to the key threshold of 1.5°C.

In an interview with The Associated Press a day before the summit is scheduled to end on Friday, U.N. Secretary-General António Guterres said the goal of capping temperature rise to 1.5 by the end of the century “is still on reach but on life support.”

Nevertheless, he added, “until the last moment, hope should be maintained.”

Guterres’ remarks came the same day a group of over 200 researchers released an open letter in which they frame COP26 as “a historic moment for the fate of climate, societies, and ecosystems.” The scientists said world leaders and negotiators must take into consideration the latest climate science in making decisions that will reverberate far into the future.

“We, climate scientists, stress that immediate, strong, rapid, sustained, and large-scale actions are necessary to hold global warming to well below 2°C and pursue efforts to limit it to 1.5°C, and thereby limit future risk and needs for adaptation over the next decades to centuries,” the group wrote.

The latest IPCC climate report “unequivocally shows the extent of human-induced climate change,” the scientists wrote, adding that “cumulative greenhouse gas emissions to date already commit our planet to key changes of the climate system affecting human society and marine and terrestrial ecosystems, some of which are irreversible for generations to come.”

The letter also points to a “rapidly shrinking” carbon budget to keep warming to 1.5°C as evidence of an “urgent need for a rapid and sustained decline of global emissions, under consideration of climate justice and equity.”

“Given the current yearly emissions of ca. 40GtCO2/yr, these remaining budgets would be exhausted by ca. 2027 to 2033 in the absence of marked decreases in emissions,” the group wrote. “This highlights the need for immediate reductions of CO2 emissions to achieve both the temperature goal of the Paris agreement and to also contribute to increased climate resilience.”

In a statement, Dr. Pep Canadell, executive director of the Global Carbon Project and one of the letter’s organizers, suggested COP26 negotiators should take the latest climate science assessment as their marching orders.

“The exceptional climate emergency we are living in requires equally exceptional national commitments and actions to bend down the trend of ever-accumulating greenhouse gas emissions in the atmosphere,” he said.

“With the well-established science on what needs to be done to stabilize the global climate,” added Canadell, “we have never been so well placed to make it happen: transform the science knowledge into commensurable actions, not words.”

Help us Prepare for Trump’s Day One

Trump is busy getting ready for Day One of his presidency – but so is Truthout.

Trump has made it no secret that he is planning a demolition-style attack on both specific communities and democracy as a whole, beginning on his first day in office. With over 25 executive orders and directives queued up for January 20, he’s promised to “launch the largest deportation program in American history,” roll back anti-discrimination protections for transgender students, and implement a “drill, drill, drill” approach to ramp up oil and gas extraction.

Organizations like Truthout are also being threatened by legislation like HR 9495, the “nonprofit killer bill” that would allow the Treasury Secretary to declare any nonprofit a “terrorist-supporting organization” and strip its tax-exempt status without due process. Progressive media like Truthout that has courageously focused on reporting on Israel’s genocide in Gaza are in the bill’s crosshairs.

As journalists, we have a responsibility to look at hard realities and communicate them to you. We hope that you, like us, can use this information to prepare for what’s to come.

And if you feel uncertain about what to do in the face of a second Trump administration, we invite you to be an indispensable part of Truthout’s preparations.

In addition to covering the widespread onslaught of draconian policy, we’re shoring up our resources for what might come next for progressive media: bad-faith lawsuits from far-right ghouls, legislation that seeks to strip us of our ability to receive tax-deductible donations, and further throttling of our reach on social media platforms owned by Trump’s sycophants.

We’re preparing right now for Trump’s Day One: building a brave coalition of movement media; reaching out to the activists, academics, and thinkers we trust to shine a light on the inner workings of authoritarianism; and planning to use journalism as a tool to equip movements to protect the people, lands, and principles most vulnerable to Trump’s destruction.

We urgently need your help to prepare. As you know, our December fundraiser is our most important of the year and will determine the scale of work we’ll be able to do in 2025. We’ve set two goals: to raise $125,000 in one-time donations and to add 1400 new monthly donors by midnight on December 31.

Today, we’re asking all of our readers to start a monthly donation or make a one-time donation – as a commitment to stand with us on day one of Trump’s presidency, and every day after that, as we produce journalism that combats authoritarianism, censorship, injustice, and misinformation. You’re an essential part of our future – please join the movement by making a tax-deductible donation today.

If you have the means to make a substantial gift, please dig deep during this critical time!

With gratitude and resolve,

Maya, Negin, Saima, and Ziggy
