End of the world SHOCK: Scientists explain ’existential threat to human civilisation’ | Weird | News

David Spratt and Ian Dunlop have warned climate change poses a “near-to-mind-term existential threat to human civilisations.” The climate researchers forecast humans would not survive past 2050 if temperatures rise 3 degrees Celsius. A total of 55 percent of the world’s populations across 35 percent of its land area would experience more than 20 day of lethal heat per year.

The researchers explained the scenario would cause the collapse of many ecosystems.

Their report on Existential climate-related security risk: A scenario approach said: “A number of ecosystems collapse, including coral reef systems, the Amazon rainforest and in the Arctic.

“Some poorer nations and regions, which lack capacity to provide artificially-cooled environments for their populations, become unviable.

“Deadly heat conditions persist for more than 100 days per year in West Africa, tropical South America, the Middle East and South-East Asia, contributing to more than a billion people being displaced from the tropical zone.

“Water availability decreases sharply in the most affected regions at lower latitudes (dry tropics and subtropics), affecting about two billion people worldwide.

“Agriculture becomes nonviable in the dry subtropics.”

The report went on the explain a 2 degrees Celsius increase would still cause more than a billion people to relocate.

They said: “The scale of destruction is beyond our capacity to model, with a high likelihood of human civilisation coming to an end.”

In the report, Chris Barrie, former head of the Australian Defence Force said: “After nuclear war, human-induced global warming is the greatest threat to human life on the planet.”

Mr Barrie warned prospects are poor without immediate drastic action.

But he did say a “doomsday future is not inevitable”.

Climate change lecturer Andrew King added the findings in the report are “plausible”.

Mr King told CNN: “Without a doubt climate change is a huge threat to human civilisation.”
