Climate change could pose ‘existential threat’ to humanity by 2050, advocates say
Above link works better. Scary stuff.
The warming will also bring more than 20 days annually of "lethal heat conditions, beyond the threshold of human survivability, scientists report. Deadly heat conditions will persist for more than 100 days a year in west Africa, tropical South America, the Middle East and southeast Asia, which will displace more than a billion people from those areas.
The destabilization of the jet stream will significantly affect the intensity and geographical distribution of monsoons in Asia and west Africa and bring more extreme devastating weather, including wildfires, heatwaves, drought and inundation, to North America.
A number of ecosystems will collapse as well, including coral reef systems and the Amazon rain forest, and water supplies will sharply decrease in the most affected regions at lower latitudes, including the dry tropics and subtropics. This will make agriculture nominal in those areas, affecting 2 billion people worldwide.'
"Massive nonlinear events in the global environment give rise to massive linear societal events," the report states. "In this scenario, nations around the world will be overwhelmed by the scale of change and pandemic disease."
The only way to avoid these results and restore the world to a safe climate would be "akin in scale to the World War II emergency mobilization" that would include implementing a zero-emissions industrial system "very quickly," according to the analysis.
"Climate change now represents a near- to mid-term existential threat to human civilization," the report states.
