Do we need a better yardstick to measure severe droughts?

ClimateWire: After more than a decade, the U.S. Drought Monitor might be due for a tuneup. As Illinois' State Climatologist Jim Angel puts it, it's like the scene in the 1984 parody of hard rock documentaries "This Is Spinal Tap" in which heavy metal guitarist Nigel Tufnel shows off his amplifiers with volume knobs that go up to 11. Tufnel's amplifiers, he brags to the filmmaker in the spoof, give his guitars that ear-splitting "extra push off the cliff" compared with traditional amps that only reach 10....

Climate Change May Increase Heavy Rains And Extend Droughts Throughout World
2013-05-05 18:29:00| Climate Ark Climate Change & Global Warming Newsfeed
Latinos Post: The change in climate may cause extreme modifications in rainfall and drought in the certain areas of the world. According to a new study by NASA, the changes in the weather increase the risk of heavier rainfalls in tropical areas and longer droughts in temperate zones. "These results in many ways are the worst of all possible worlds," Peter Gleick, climatologist, water expert and president of the research organization, Pacific Institute, said as reported by LA Times. "Wet areas will get wetter...

NASA: Warming Climate Likely Means More Floods, Droughts
2013-05-03 20:24:00| Climate Ark Climate Change & Global Warming Newsfeed
National Public Radio: The Earth's wettest regions are likely to get wetter while the most arid will get drier due to warming of the atmosphere caused by increased levels of carbon dioxide, according to a new NASA analysis of more than a dozen climate models. Scientists ran simulations of 14 different models, starting with CO2 concentrations at about 280 parts per million, which is similar to preindustrial levels but well below the 400 parts per million today. The amount of carbon dioxide was then bumped up by 1 percent...

Climate's role in US droughts is under scrutiny
2013-04-20 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
New Scientist: CAN the extreme drought that devastated crops across the US Midwest in 2012 be blamed on global warming? Probably not, according to a report from the US National Oceanic and Atmospheric Administration (NOAA). But the conclusion has been met with stinging criticism from another leading climate scientist. The controversy highlights the need for better methods to assess if and how extreme weather events are linked to climate change. Martin Hoerling of NOAA's Earth System Research Laboratory in...

Climate change models fail to accurately simulate droughts
2013-04-18 19:07:00| Climate Ark Climate Change & Global Warming Newsfeed
Scientific American: Most of my day job involves simulating the behavior of molecules like drugs and proteins using computer models. The field is more an art than a science, partially because the systems that are being modeled are too complex and ill-understood to succumb to exact solutions. Success often depends on experience and intuition gained by working on similar systems. That does not mean there are no correct predictions, but it does mean that surprises are more common than we think and that many phenomena are...
