Disappearing Climate Zones Mean Disappearing Species

A new study forecasts the complete disappearance of existing climates in tropical highlands and regions near the poles. Meanwhile large swaths of the tropics and subtropics will likely develop new climates unlike any seen today, according to the National Science Foundation. Researchers at the University of Wisconsin-Madison and the University of Wyoming predict that existing climate zones will shift toward higher latitudes and higher elevations, squeezing out the climates at the extremes. In fact a lot of this is already underway, as species are already moving to higher latitudes and higher elevations to escape the heat.

The most severely affected parts of the world span heavily populated regions, including the southeastern U.S., southeastern Asia, parts of Africa. Known hotspots of biodiversity, including the Amazonian rainforest and African and South American mountain ranges will also experience radical change. Disappearing climates will affect biodiversity, increasing extinctions too.

The study’s authors foresee the appearance of never-before-seen climate zones on up to 39 percent of the world’s land surface area by 2100, and the global disappearance of up to 48 percent of current land climates, if current rates of carbon dioxide and other greenhouse gas emissions continue.

WE'RE TAKING A SHORT BREAK…

from the big banner at the top of our pages asking for the donations that make Mother Jones' nonprofit journalism possible. But we still have upwards of $300,000 to raise by June 30, whether we get there is going to come down to the wire, and we can't afford to come up short.

If you value the reporting you get from Mother Jones and you can right now, please join your fellow readers who pitch in from time to time to keep our democracy-advancing, justice-seeking journalism charging hard (and to help us avoid a real budget crunch as June 30 approaches and our fiscal year ends).
