The Alliance is an international assembly of scientists, independent of both governmental and non-governmental organizations. As stewards of human knowledge and champions of evidence-based decision making, the goal of the Alliance is to be an amplifying voice for scientists all over the world. To prevent further widespread catastrophic damage to the biosphere, humanity must practice more environmentally sustainable alternatives to business-as-usual. As the only independent, a grass-roots organization comprised of diverse scientific experience, the Alliance is committed to the well-being of the planet and all life it holds. The Alliance is a partner with the Conservation Biology Institute.
Join the Alliance!
All scientists are invited to join the Alliance of World Scientists by signing a short article on climate change. We welcome signatures of scientists from any scientific discipline, including graduate students in the sciences. Note that signatories speak on their own behalf and not on behalf of their affiliated institutions.
New signatures may take several weeks to appear in the list of signatories as each name will first need to be validated. Please only sign the article once.
Climate Feedback Loops Project
There are many amplifying global feedback loops that significantly increase warming due to greenhouse gas emissions. However, not all of these feedbacks are fully accounted for in current climate models. Thus, potential mitigation pathways based on these models could be overly optimistic and fail to sufficiently limit temperatures. A targeted expansion of research is needed to incorporate biologically-based feedbacks into Earth system models to guide climate policy objectives. Concurrently, policymakers must implement plans to minimize risks by greatly accelerating the reduction of greenhouse gas emissions.
A. Arctic warming leads to melting sea ice, which leads to further warming due to water having lower albedo (reflectance) than ice.
B. Increasing temperatures lead to permafrost thawing which produces CO2 and methane emissions, which in turn leads to further increasing temperatures.
C. Rising temperatures lead to increasing fire frequency/severity causing increasing CO2 emissions, loss of sequestration, and changes in albedo, thus causing further warming.
