Climate change threatens corn crops

PhysOrg: A warming world is putting crops at risk, according to scientists who studied how the weather affects French maize yields. If climate-change projections are right, we'll need to improve yields per acre by as much as 12 per cent between 2016 and 2035 just to maintain today's total production. The results reveal a real threat to our food supply in the coming decades. It turns out that maize yields drop significantly for every day when temperatures climb over around 32°C, and that heat stress...

Climate Change 'Causes Wild Weather'
2013-02-28 09:38:00| Climate Ark Climate Change & Global Warming Newsfeed
Truthdig: The cause of much of the recent extreme weather across the world is climate change triggered by human activities, scientists say. The Earth has experienced a range of severe regional weather extremes in recent years, including the heat waves of 2011 in the US and 2010 in Russia, a year that also brought the unprecedented Pakistan floods. Behind these distinct events, though, there is a common physical cause, according to a team at the Potsdam Institute for Climate Impact Research (PIK), Germany....

Are climate change models becoming more accurate and less reliable?
2013-02-27 21:04:00| Climate Ark Climate Change & Global Warming Newsfeed
Scientific American: One of the perpetual challenges in my career as a modeler of biochemical systems has been the need to balance accuracy with reliability. This paradox is not as strange as it seems. Typically when you build a model you include a lot of approximations supposed to make the modeling process easier; ideally you want a model to be as simple as possible and contain as few parameters as possible. But this strategy does not work all the time since sometimes it turns out that in your drive for simplicity you...

Climate Change: Get Ready to Adapt!

Huffington Post: WB President Jim Yong Kim's recent Washington Post op-ed "Make Climate Change a Priority" warned that "global warming imperils all of the development gains we have made". Jim Kim drew on a recent World Bank report that points to the possibility for global temperatures to rise by 4 degrees Celsius or more by the end of the century, with severe natural, economic and social impacts. Jim Kim's call is all the more urgent given how grim are actual trends on efforts to mitigate greenhouse gas emissions....

Climate change makes every house in Delaware a 'beach home'

Newsworks: Sen. James Imhoff (R-OK) is noted for suggesting that climate change is the greatest hoax ever perpetrated on the American people. He's also the ranking minority members on the Senate's Environment and Public Works committee. Wonder why nothing ever gets done about climate change? I would invite Imhoff and all his neanderthal colleagues down to Delaware, where up to 11 percent of the state could be swept away by flooding next century due to rising sea levels. It might be hard for Imhoff and...
