Droughts could kill many of the world's trees

LiveScience: Drought could kill vast swaths of forests around the world if global warming isn't contained, new research suggests. That's in part because a fundamental structure found in trees may limit how much they can adapt to parched conditions. What's more, climate predictions seem to suggest that droughts will be much more common in the United States, said William Anderegg, a biologist at Princeton University who studies forests and climate change.

Ancient pollen reveals droughts between Sierra Nevada glacier surges

ScienceDaily: Hidden below the surface of California's Central Valley are pollen grains from the Pleistocene that are providing scientists with clues to the severity of droughts that struck the region between glacial periods. The Pleistocene -- the age of mammoths and mastodons -- occurred between 1.8 million and 11,500 years ago. For this new study, scientists dug up Pleistocene sediment samples containing buried pollen from the Central Valley. They found that pollen samples dated from interglacial periods --...

California faces a future of droughts alternating with floods
2015-10-23 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
InsideClimate: A warming climate coupled with more intense El Nio and La Nia events could cause twice as many droughts and three times as many floods in California by 2080, according to a study published Wednesday in the journal Nature Communications. The findings come while California suffers its most severe drought in recorded history, a four-year disaster that has caused an estimated $2.2 billion in economic loss from 2013-14 alone. At the same time, heavy rainfallwhich triggered mudslides last week in...

Study: Overlapping Droughts, Heat Waves Are Increasingly Common
2015-09-03 17:48:00| Climate Ark Climate Change & Global Warming Newsfeed
Christian Science Monitor: Across much of the United States, regional droughts and heatwaves are appearing simultaneously more frequently, imposing more-extreme conditions than either would deliver separately, according to a new study. California's four-year drought is a case in point, says Amir AghaKouchak, a civil engineer at the University of California at Irvine and the new study's senior author. Looking only at 2014 and using precipitation as the indicator, "it is a serious drought, but it is not that extreme," he says....

Droughts and Heat Waves Are Occurring Together
2015-09-03 13:57:00| Climate Ark Climate Change & Global Warming Newsfeed
Clapway: Stories of extended droughts and heat waves have repeatedly been making news headlines. According to scientists, these climatic weather fluctuations are occurring much more frequently, further shedding light on the potentially devastating effects of climate change. To make matters even worse, a study, published Monday in the Proceedings of the National Academy of Sciences, now reports that these extremes are also more likely to occur together.
