Climate Crisis Is on Track to Push One-Third of Humanity Out of Its Most Livable Environment

Climate change is remapping where humans can exist on the planet. As optimum conditions shift away from the equator and toward the poles, more than 600 million people have already been stranded outside of a crucial environmental niche that scientists say best supports life. By late this century 3 to 6 billion people, or between a third and a half of humanity, could be trapped outside of that zone, facing extreme heat, food scarcity and higher death rates, unless emissions are sharply curtailed or mass migration is accommodated.

Pandoravirus: the melting Arctic is releasing ancient germs – how worried should we be?

All the viruses cultured so far are far from viruses that affect mammals, let alone, humans and would be very unlikely to pose a danger to humans. A more relevant area of concern is that as the permafrost thaws it could release the bodies of long-dead people who might have died of an infectious disease and so release that infection back into the world.
