Reshaping mountains human mind save species facing climate change

ScienceDaily: People commonly perceive mountain ranges as jumbles of pyramid-shaped masses that steadily narrow as they slope upward. While that's certainly how they appear from a ground-level human viewpoint, new research shows that pyramid-shaped mountains are not only a minority in nature, but also that most ranges actually increase in area at higher elevations. Besides reshaping the mountains in our mind's eye, the findings could lead scientists to reconsider conservation strategies -- which are often based...
Lower Ozone levels in Houston linked to climate change
2015-05-18 23:02:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Researchers at the University of Houston have determined that climate change -- in the form of a stronger sea breeze, the result of warmer soil temperatures -- contributed to the drop in high-ozone days in the Houston area. Robert Talbot, professor of atmospheric chemistry, said that also should be true for coastal regions globally. The researchers describe their findings in a paper published this week in the journal Atmosphere. In addition to Talbot, they include first author Lei Liu, a doctoral...

Canada: Bird populations responding to climate change
2015-05-18 23:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Environmental News Network: With puzzling variability, vast numbers of birds from Canadas boreal forests migrate hundreds or thousands of miles south from their usual winter range. These so-called irruptions were first noticed by birdwatchers decades ago, but the driving factors have never been fully explained. Now scientists have pinpointed the climate pattern that likely sets the stage for irruptions a discovery that could make it possible to predict the events more than a year in advance. The researchers found that...

Studies: Climate change to bring more heat waves, stronger hurricanes

USA Today: Talk about your summer bummer. The number of Americans sweltering through stifling heat waves could well quadruple over the next few decades, according to a study Monday in the British journal Nature Climate Change. As if that weren't enough, a separate study in the same journal said hurricanes are likely to become more intense, even as their number declines. In the heat wave study, researchers said people living in Atlanta, Charlotte, Dallas, Houston, Oklahoma City, Phoenix, Tampa and San...

Climate change threatens electric power supply in California, report warns
2015-05-18 22:01:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: Californians may have to start rationing more than water, including how much they turn on their lights and how often they use their hairdryers. By 2050, extended years of drought in the state could lead to an electricity shortage as well as a water shortage, according to a study published on Monday in the journal Nature Climate Change. In the study, Arizona State University authors Matthew Bartos and Mikhail Chester found that almost half (46%) of 978 electric power stations in the western...
