Warmist Trenberth sees carbon dioxide causing "major strife, conflicts, and loss of population"; comrade Michael Mann suggests "mass exodus, creating environmental refugees"

Climate Scientists Applaud Dire World Bank Report | Global Warming | LiveScience

"The World Bank did a great service to society by issuing this report," said Michael Mann, a climate researcher at Pennsylvania State University and the author of "The Hockey Stick and the Climate Wars" (Columbia University Press, 2012).

Climate deniers often claim that solutions to global warming are part of a "global socialist agenda," Mann told LiveScience.

"The fact that the World Bank — an entity committed to free market capitalism — has weighed in on the threat of climate change and the urgency of acting to combat it, puts the nail in the coffin of that claim," he said.

"I am inclined to think that things will break before we get there," Kevin Trenberth, a climate scientist at the National Center for Atmospheric Research, said of a 4-degree-C world. Ecosystems would change so much and agriculture would be so disrupted that the result would likely be "major strife, conflicts and loss of population," Trenberth told LiveScience.
...Areas becoming unsustainable would likely lead to mass exodus, creating environmental refugees, Mann said.

"The alternative energies (wind, solar, geothermal, etc) are there," Mann wrote in an email to LiveScience. "We just need to deploy and scale them up by investing immediately in the necessary infrastructure."
