I en artikel publiceret i det anerkendte internationale tidsskrift journal Proceedings of the National Academy of Sciences argumenterer et hold forskere for, at der er behov for mere forskning i worst-case klimascenarier, der spænder fra 10 % tab til total udryddelse af menneskeheden.
Ifølge forskerne bruges der alt for få ressourcer på at forstå følgerne af temperaturstigninger på 3° og derover – selvom sådanne stigninger formentlig vil have enorme konsekvenser for menneskeheden.
I forbindelse med offentliggørelse af artiklen udtaler hovedforfatteren, Luke Kemp fra Cambridge University, blandt andet:
“There are plenty of reasons to believe climate change could become catastrophic, even at modest levels of warming. Climate change has played a role in every mass extinction event. It has helped fell empires and shaped history. Even the modern world seems adapted to a particular climate niche.”
“Paths to disaster are not limited to the direct impacts of high temperatures, such as extreme weather events. Knock-on effects such as financial crises, conflict, and new disease outbreaks could trigger other calamities, and impede recovery from potential disasters such as nuclear war. The catastrophic risk is there, but we need a more detailed picture.”
