The global warming could become “catastrophic” for the humanity whether the temperature rise is worse than many predict or triggers a cascade of events not yet factored in, or both. “The world needs to start preparing for the possibility of a ‘climate endgame'”

This is confirmed by an international team of researchers led by the University of Cambridgewhich proposes an agenda to deal with the worst scenarios. These include outcomes ranging from the loss of 10% of the world’s population to eventual human extinction.

The team responsible for the article PNAS offers a research program that includes what they call the “four horsemen” of the end of the climate: famine and malnutrition, extreme weather conditions, conflict and vector-borne diseases.

Rising temperatures pose major threat to global food supply and could create the conditions for new epidemics as the habitats of people and wildlife change and shrink.

For scientist Kristie Ebi of the University of Washington, “We need an interdisciplinary effort to understand how climate change could trigger massive morbidity and mortality in humans.”

Specifically, in an article published in the journal PNAScall on the Intergovernmental Panel on Climate Change (IPCC) to devote a future report to catastrophic climate change to boost research and inform the public.

“There are many reasons to believe that climate change could become catastrophic, even with modest levels of warming,” notes lead author Luke Kemp.

“The pathways to disaster are not limited to the direct impacts of high temperatures, such as extreme weather events. Ripple effects, such as financial crises, conflicts and new epidemics, could trigger further calamities and hamper recovery from potential disasters, such as nuclear war.

In 2070, these temperatures and their social and political consequences will directly affect two nuclear powers and seven maximum containment laboratories that harbor pathogens

The modeling conducted by the team shows that areas of extreme heat (an average annual temperature of more than 29 degrees) could reach two billion people in 2070; These areas are not only among the most densely populated, but also among the most politically fragile.

“Average annual temperatures of 29 degrees currently affect around 30 million people in the Sahara and on the Gulf Coast,” details Chi Xu from Nanjing University.

“In 2070, these temperatures and the social and political consequences will directly affect two nuclear powers and seven maximum containment laboratories that house the most dangerous pathogens. There is a high chance of disastrous side effects.” He says.

In addition, climate collapse would likely exacerbate other threats: from rising inequality and misinformation to democratic collapse and even new forms of destructive artificial intelligence arsenals.
