Warming Climate May Drive Human Conflict
2013-08-16 11:57:00| Climate Ark Climate Change & Global Warming Newsfeed
Scientific American: Tempers flare as temperatures rise -- across the globe and throughout human history, researchers have found. The result is consistent with a growing body of research suggesting that climate change somehow incites human conflict. Small changes in temperature and rainfall substantially raise the risk of conflict of many types, from interpersonal spats -- such as aggressive horn-honking by automobile drivers -- to full-blown civil war and societal collapse, researchers report today in Science. They...

Warming Climate Pushes Plants Up the Mountain
2013-08-15 16:36:00| Climate Ark Climate Change & Global Warming Newsfeed
EcoWatch: In a rare opportunity to directly compare today`s plant communities with a survey taken in the same area 50 years ago, a University of Arizona (UA)-led research team has provided the first on-the-ground evidence that Southwestern plants are being pushed to higher elevations by an increasingly warmer and drier climate. The researchers assessed plants growing at different elevations in the same areas surveyed by botanists 50 years ago. Photo credit: Jeffrey Eble. The findings confirm that previous...

No Clear Sign That Less Soot, Methane Reduces Global Warming
2013-08-14 16:18:00| Climate Ark Climate Change & Global Warming Newsfeed
RedOrbit: Reducing emissions of only soot and methane won`t do as much to reduce global warming as some previous research has suggested, according to a new study published Monday in the Proceedings of the National Academy of Sciences (PNAS). "Cutting back only on soot and methane emissions will help the climate, but not as much as previously thought," said study author Steve Smith, a climate researcher at the Department of Energy`s Pacific Northwest National Laboratory (PNL). The researchers advise focusing...

Global warming: Forests cant win for losing
2013-08-14 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Summit County: Even if trees aren`t directly killed by drought, the ongoing stress of dry conditions can lead to more tree mortality in the aftermath of forest fires and prescribed burns. The findings come from a new study that took a close look at varied forest types around the west, including in Colorado`s Rocky Mountain National Park. Most of the data was compiled in areas where agencies conducted prescribed fires between 1984 and 2005. The researchers looked at more than 7,000 individual conifers. They...

A grand solar minimum would barely make a dent in human-caused global warming
2013-08-14 06:58:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: Recent articles in the Danish newspaper Jyllands-Posten (translation available here) and in the Irish Times both ran headlines claiming that another grand solar minimum could potentially trigger an "ice age" or "mini ice age" this century. These articles actually refer to the Little Ice Age (LIA) a period about 500 to 150 years ago when global surface temperatures were approximately 1°C colder than they are today. This is quite different from an ice age, which are more like 5°C colder than today....
