Even as concentrations of carbon dioxide in the atmosphere hit 400 parts per million (ppm) for the first time in human history recently, a new study in Nature Climate Change warns that thousands of the world’s common species will suffer grave habitat loss under climate change, reports Jeremy Hance at Mongabay. Looking at the habitat requirements of nearly 50,000 common land plant and animal species, scientists found that about a third of the animals and over half of the plants will see over half of their habitat lost by 2080 if temperatures rise about 7 degrees Fahrenheit above the pre-industrial average. According to the study, plants, reptiles, and amphibians are the most vulnerable, while the Amazon, Central America, Sub-Saharan Africa, and Australia are expected to be the hardest hit. Even worse, the estimates are “probably conservative” since they didn’t take into account rising extreme weather, disease, and pests… Animals in particular may decline more … compounded by a loss of food from plants.” The sooner carbon emissions peak and start declining, the study noted, the more we can avert losses of life on Earth.
Join the swelling numbers of voters TELLING Congress they’ll vote for Clean Energy candidates here: http://signon.org/sign/we-are-the-clean-99?source=c.em.cp&r_by=487176 . This is an ongoing campaign (the next Congressional election is in 2 years!) so please, spread the word. It’s our way of telling Congress that a strong clean energy voting bloc is out there. This is how YOU can make a difference.

Climate change to halve habitat for over 10,000 common species
(05/13/2013) Even as concentrations of carbon dioxide in the atmosphere hit 400 parts per million (ppm) for the first time in human history last week, a new study in Nature Climate Change warns that thousands of the world’s common species will suffer grave habitat loss under climate change.
