Climate change could trigger nuclear war or a deadly pandemic in 2070

The analysis, published in the journal Proceedings of the National Academy of Sciences, was reviewed by a dozen scientists. He argues that the consequences of global warming beyond 3°C have been under-examinedwith few quantitative estimates of total impacts.

The researchers call on the Intergovernmental Panel on Climate Change (IPCC) to dedicate a future report to catastrophic climate change, which must include outcomes ranging from the loss of ten percent of the human population to eventual extinction. to promote research and inform the public.

“Average annual temperatures of 29 degrees currently affect about 30 million of people in the Sahara and the Gulf Coast,” said Chi Xu, an expert in ecological systems complexity at Nanjing University and a co-author of the paper.By 2070, these temperatures and the social and political consequences will directly affect two nuclear powers and seven maximum containment laboratories that harbor the most dangerous pathogens. There is great potential for disastrous side effects.”

The current trend of Emissions of greenhouse gases would lead to a rise of 2.1 to 3.9°C by 2100. But if existing promises of action are fully implemented, the range would be 1.9 to 3°C. Meeting all the long-term targets set to date would mean 1.7 to 2.6°C of warming.

Facing a future of accelerating climate change while remaining blind to worst-case scenarios is naive risk management at best and fatally foolish at worst.

More research is needed to identify all possible tipping points leading to a “Hothouse Earth.” “The more we learn about how our planet works, the greater the cause for concern,” said Johan Rockström, director of the Potsdam Institute for Climate Impact Research. “We understand more and more that our planet is a more sophisticated and fragile organism. We must make the calculations of the disaster to avoid it”.
