Slowdown of global warming fleeting

TGDaily: The recent slowdown in the warming rate of the Northern Hemisphere may be a result of internal variability of the Atlantic Multidecadal Oscillation -- a natural phenomenon related to sea surface temperatures, according to Penn State researchers. "Some researchers have in the past attributed a portion of Northern Hemispheric warming to a warm phase of the AMO," said Michael E. Mann, Distinguished Professor of Meteorology. "The true AMO signal, instead, appears likely to have been in a cooling phase...

Global Warming Reduces the Quality of Food Crops
2014-04-08 09:39:00| Climate Ark Climate Change & Global Warming Newsfeed
Softpedia: Wheat sustains around a quarter of the world's population Scientists at the University of California in Davis (UCD) have determined in a new study that the quality of food crops will continuously decline as global warming intensifies. The more time passes before climate change is addressed, the poorer our foods will get. This is the first time these conclusions were verified in a field test, investigators say. This effect largely occurs because elevated levels of carbon dioxide in the atmosphere...

Time running out to meet global warming target: U.N. report
2014-04-06 13:01:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: World powers are running out of time to slash their use of high-polluting fossil fuels and stay below agreed limits on global warming, a draft U.N. study to be approved this week shows. Government officials and top climate scientists will meet in Berlin from April 7-12 to review the 29-page draft that also estimates the needed shift to low-carbon energies would cost between two and six percent of world output by 2050. It says nations will have to impose drastic curbs on their still rising greenhouse...
Global warming could dry out a third of the Earth by 2100

Salon: Forget changing rain patterns - warmer temperatures alone could bring drought to a third of Earth`s land area by the end of the century. That`s the gist of a new study from Columbia University`s Earth Observatory: Hotter temperatures will mean more evaporation, drying out the soil and posing a significant risk to global agriculture and food security. Climate Central has the details: Climate models using the so-called business-as-usual greenhouse gas emissions scenario, which assumes no effort...
IPCC: Global Warming Impacts May Be Irreversible

Environment News Service: The effects of climate change are "already occurring on all continents and across the oceans," yet the world is "ill-prepared for risks from a changing climate," concludes the latest assessment, issued today, from the Intergovernmental Panel on Climate Change. "Increasing magnitudes of warming increase the likelihood of severe and pervasive impacts that may be surprising or irreversible," warns the report from the UN panel The assessment, titled "Climate Change 2014: Impacts, Adaptation, and...
