The AWS provides the collective international voice of thousands of scientists regarding the global climate crisis and environmental trends with the intent to turn accumulated knowledge into action.
We invite all scientists to join the Alliance of World Scientists by signing a short article on climate change
If you are a scientist, we invite you to join the Alliance of World Scientists by signing our Viewpoint article “World Scientists’ Warning of a Climate Emergency” by Ripple et al., which was recently published in BioScience Magazine. We welcome signatures of scientists from any scientific discipline, including graduate students in the sciences. Before signing, we ask that you view this short article by clicking the “Read the Article” tab below (the main text can be read in < 8 minutes), or read the condensed version directly below. When you click “sign the article” and add your name, you will be indicating that you generally agree with our article, helping get this message to world leaders. Note that signatories speak on their own behalf and not on behalf of their affiliated institutions. It may not be possible to sign the article using Internet Explorer, but other web browsers seem to be working. New signatures may take several weeks to appear in the list of signatories because each name will first need to be validated. Please only sign the article once.

World Scientists’ Warning of a Climate Emergency (Condensed Version)
William J. Ripple, Christopher Wolf, Thomas M. Newsome, Phoebe Barnard, William R. Moomaw
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.
The Alliance of World Scientists (AWS)
The AWS is a new international assembly of scientists, which is independent of both governmental and non-governmental organizations and corporations. We submit, that in order to prevent widespread misery caused by catastrophic damage to the biosphere, humanity must practice more environmentally sustainable alternative to business-as-usual. Our vital importance and role comes from scientists' unique responsibility as stewards of human knowledge and champions of evidence-based decision-making. The main goal of the AWS is to be a collective international voice of many scientists regarding global climate and environmental trends and how to turn accumulated knowledge into action. Other organizations do laudable work toward this goal, but to our knowledge, AWS is the only independent, grass-roots organization comprised of scientists from around the world committed to the well-being of humanity and the planet. Dr. Bill Ripple and Dr. Chris Wolf serve as Director and Associate Director of the AWS respectively.
When you endorse the scientists’ warning article, you will have the option of including your email address for occasional communication or additional collaboration as part of the AWS.
