Study: Global warming to push 1 in 13 species to extinction

Associated Press: Global warming will eventually push 1 out of every 13 species on Earth into extinction, a new study projects. It won't quite be as bad in North America, where only 1 in 20 species will be killed off because of climate change or Europe where the extinction rate is nearly as small. But in South America, that forecasted heat-caused extinction rate soars to 23 percent, the worst for any continent, according to a new study published Thursday in the journal Science. University of Connecticut ecologist...

Species' evolutionary choice: Disperse or adapt?

2015-05-01 12:00:00| LifeSciencesWorld

[NEWS] Dispersal and adaptation are two fundamental evolutionary strategies available to species given an environment. Generalists, like dandelions, send their offspring far and wide. Specialists, like alpine flowers, adapt to the conditions of a particular place. Ecologists have typically modeled these two strategies, and the selective pressures that trigger them, by holding one strategy fixed and watching how the other evolves. New research published in the journal Evolution</e…

Climate change could push a sixth of species to extinction: study

Reuters: Climate change could drive up to a sixth of animals and plants on Earth to extinction unless governments cut rising greenhouse gas emissions, according to a U.S. study published on Thursday. Species in South America, Australia and New Zealand are most at risk, since many live in small areas or cannot easily move away to adapt to heatwaves, droughts, floods or rising seas, said the report in the journal Science. The study averaged out 131 previous studies of climate change, whose projections...

Climate change could eventually claim a sixth of the world's species

2015-04-30 20:35:00| Climate Ark Climate Change & Global Warming Newsfeed

Science: Up to one-sixth of the species on Earth could disappear if climate change remains on its current course, according to a new analysis of more than 100 smaller studies. All the studies are in pretty good agreement: The more warming we have, the more species well lose, says Dov Sax, a conservation biologist at Brown University who was not involved in the work. This is really important to know, from a policy viewpoint. Industrial emissions of carbon dioxide and other planet-warming greenhouse...
