“Humanity’s mortality moment”: Scientists’ restate climate warning


Earlier this year, over 11,000 scientists from around the world issued a signed warning stating “clearly and unequivocally that planet Earth is facing a climate emergency”. At the ongoing CoP-25 climate talks at Madrid, Dr. William Moomaw, one of the report’s co-authors, explains the nature of that emergency, and what we must do about it.

World Scientists’ Warning of a Climate Emergency (Condensed Version)

William J. Ripple, Christopher Wolf, Thomas M. Newsome, Phoebe Barnard & William R. Moomaw and 11,000+ signatories

We scientists have a moral obligation to clearly warn humanity of any catastrophic threat. In this paper, we present a suite of graphical vital signs of climate change over the last 40 years. Results show greenhouse gas emissions are still rising, with increasingly damaging effects. With few exceptions, we are largely failing to address this predicament. The climate crisis has arrived and is accelerating faster than many scientists expected. It is more severe than anticipated, threatening natural ecosystems and the fate of humanity. We suggest six critical and interrelated steps that governments and the rest of humanity can take to lessen the worst effects of climate change, covering 1) Energy, 2) Short-lived pollutants, 3) Nature, 4) Food, 5) Economy, and 6) Population. Mitigating and adapting to climate change entails transformations in the ways we govern, manage, feed, and fulfill material and energy requirements. We are encouraged by a recent global surge of concern. Governmental bodies are making climate emergency declarations. The Pope issued an encyclical on climate change. Schoolchildren are striking. Ecocide lawsuits are proceeding in the courts. Grassroots citizen movements are demanding change. As scientists, we urge widespread use of our vital signs and anticipate that graphical indicators will better allow policymakers and the public to understand the magnitude of this crisis, track progress, and realign priorities to alleviate climate change. The good news is that such transformative change, with social and ecological justice, promises greater human wellbeing in the long-run than business as usual. We believe that prospects will be greatest if policy makers and the rest of humanity promptly respond to our warning and declaration of a climate emergency, and act to sustain life on planet Earth, our only home.

CRITICAL TAKE

Why “Warning to Humanity” gets the global crises (and its solutions) wrong
Entitle Blog
The “Warning to Humanity” signed by more than 15.000 scientists calls for action to save the planet proposing elitist environmentalism and missing the real target. The problem is not in the “barbarian hordes” and the “overpopulation bogeyman” but in the West’s “imperial mode of living” that is now expanding around the world.

A second warning to humanity, from the world’s scientists
Ecologise
Mankind is facing the existential threat of runaway consumption of limited resources by a rapidly growing population, says a new, dire “warning to humanity” written by 15,000 scientists from 184 countries.The message updates an original warning sent 25 years ago. The experts say the picture now is far, far worse than it was in 1992.

UN says climate genocide is coming. It’s actually worse.
David Wallace-Wells, NY Mag
We’re on track for four degrees of warming, more than twice as much as most scientists believe is possible to endure without inflicting climate suffering on hundreds of millions or threatening at least parts of what we call, grandly, “civilization.” The only thing that changed is that the scientists, finally, have hit the panic button.

‘Tail Risk’: What the scientists are not telling you about climate change
Kerry Emanuel 
There are strong cultural biases against discussion of ‘tail risk’ in climate science; particularly the accusation of “alarmism”. Does the dictum to tell “the truth, the whole truth, and nothing but the truth” not apply to climate scientists? If we omit discussion of tail risk, are we really telling the whole truth?

Scientists say a long feared climate ‘feedback’ is now happening
Chris Mooney, The Washington Post
In a massive new study published in the influential journal Nature, more than 50 authors from around the world document a so-called climate system “feedback” that, they say, could make global warming considerably worse over the coming decades. That feedback involves the planet’s soils, which are a massive repository of carbon.

    Scientists should quickly come up with a term that means a fraction of a degree. E.g. like a millidegree, or nanodegree. People cannot fully comprehend the world of difference between between 1.5 degrees and 2 degrees, but if you say it is the difference between 1500 millidegrees and 2000 millidegrees, 500 millidegrees! they start to see the difference. Example: Temperatures are rising, we are now at 127 millidegrees, we are going to reach 128 millidegrees on 1 February. It is helpful to break down the “degree” for the sake of effective communication and advocacy. Please do it!
