Buzzkill: global warming shrinks range pollinating bumblebees
2015-07-10 00:03:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: Global warming is shrinking the terrain where bumblebees live in North America and Europe, with these vital pollinators departing the southernmost and hottest parts of their ranges while failing to move north into cooler climes, scientists say. Their study, published on Thursday, used records from 1901 to 2010 to track 67 bumblebee species, finding that the insects have surrendered about 185 miles (300 km) from the southern end of the regions they called home on both continents. The researchers...

Global sea levels have risen six meters or more with just slight global warming
2015-07-09 23:02:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: A new review analyzing three decades of research on the historic effects of melting polar ice sheets found that global sea levels have risen at least six meters, or about 20 feet, above present levels on multiple occasions over the past three million years. What is most concerning, scientists say, is that amount of melting was caused by an increase of only 1-2 degrees (Celsius) in global mean temperatures. Results of the study are being published this week in the journal Science. "Studies...
How 2°C of Warming Could Reshape the U.S
2015-07-09 23:01:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate Central: If, as suggested by a comprehensive new review in the journal Science, 2°C of global warming would lock in at least 20 feet (6 meters) of eventual sea level rise, what would that warming mean for the future and heritage of the U.S.? It would mean a map we don't recognize: Louisiana would shed its boot, the Eastern seaboard would seriously retract, and the Bay Area would grow a second inland bay -- as the nation would lose more than 48,000 square miles of land, home today to 23.4 million people....
Volcanoes Cooled Earth in Past, Constrain Warming from Excess CO2
2015-07-09 16:29:00| Climate Ark Climate Change & Global Warming Newsfeed
ClimateWire: A powerful blast of cosmic rayscarrying the energy of 167 megatons of TNTentered Earth from a star 1,200 years ago and filled the remote reaches of the Earth with beryllium, carbon isotopes and other elements. The cosmic event left its imprint in tree rings and ice cores, which are natural history books for times before the human era. And using it, scientists have resolved a long-standing argument on how the planet responds to volcanic eruptions. They have found that almost every major volcanic...

It's warming faster in cities - but there are cooling solutions, scientists say
2015-07-09 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Online Athens: The world is steadily heating up as the levels of carbon dioxide and other greenhouse gases accumulate in the atmosphere. But cities are heating up even faster, which could have serious consequences for city dwellers in upcoming years. As heat waves become more common and more intense, the suffering will likely fall hardest on the most vulnerable groups, such as the poor, the elderly and people who work out of doors, University of Georgia climate scientist Marshall Shepherd said this week as a...
