Global warming is changing soil chemistry, to the detriment of plant growth in the worlds dry regions
2013-11-04 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Summit County: After studying soil samples at more than 200 sites worldwide in a networked research projects, scientists say global warming is likely to change the balance of soil nutrients in drylands -- to the detriment of plant growth. Drylands cover about 41 percent of the earths surface. The study suggests that people -- about 20 percent of the world`s population -- who depend on those ecosystems for crops, livestock forage, fuel and fiber will find their resources increasingly restrained. The findings...

Global Warming Could Shrink Mammal Size
2013-11-04 12:32:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World News: Global warming in the past shrunk the size of mammals and according to experts, it might happen again. Philip Gingerich at University of Michigan and his colleagues recently presented a research at the Society of Vertebrate Paleontology. They said that there is enough evidence to support the idea that mammals could shrink in size due human-led global warming. Previous research, too, has shown that rising carbon dioxide levels could reduce animal body size in the future. The first time global...

Polar bear attacks: scientists warn of fresh dangers in warming Arctic
2013-11-04 08:44:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: A polar bear attack in Canada that left two people injured has brought new warnings from scientists of a dangerous rise in human-bear encounters in a warming Arctic. The friends had just walked out of the door in the pre-dawn hours after a party when the young polar bear crept up behind them, unheard and unseen. By the time, the bear was driven off by neighbours wielding a shovel, banging pots and pans, and firing multiple rounds from a shotgun, two people were badly mauled: the young woman...

Cleaner cookstoves can boost health and slow global warming
2013-11-04 08:16:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: Cleaner cookstoves could save a million lives every year, but costs need to decrease sharply for poor households in developing countries to be able to afford them, according to a World Bank report. On thin ice: how cutting pollution can slow warming and save lives, published on Sunday evening, calls for action to reduce common pollutants such as soot, known as black carbon, to not only slow global warming, but prevent millions of deaths. It warns that climate change in the cryosphere snow-capped...

Global Warming Seen Taking Toll on Economy, Health, Crops
2013-11-04 07:06:00| Climate Ark Climate Change & Global Warming Newsfeed
Bloomberg: Global warming is expected to take an increasing toll on the economy, food production, fresh water supplies and human health as the century progresses, according to a draft study for the United Nations. A temperature increase of 2.5 degrees Celsius (4.5 degrees Fahrenheit) since industrialization may lead to losses of as much as 2 percent of global economic output, an analysis by the UNs Intergovernmental Panel on Climate Change showed. Temperatures have already risen by about 0.8 degrees. The...
