‘Nuisance Flooding’ Will Affect Most of U.S. Coastline by 2050, Report Finds
Posted by Washington Post: Juliet Eilperin on December 19th, 2014
Yale Environment 360: By 2050, most U.S. coastal areas are likely to be threatened by 30 or more days of flooding each year due sea level rise, according to a new report the National Oceanic and Atmospheric Administration (NOAA). The researchers looked at the frequency of so-called "nuisance flooding," which occurs when the water level reaches one to two feet above local high tide, and found that several cities along the East Coast are already seeing more than 30 days of nuisance flooding each year. Additional major cities...

Posted by Washington Post: Juliet Eilperin on December 19th, 2014
BBC: Any moves to modify the Los Angeles River, to return parts of it to a more natural setting or to capture water, need to be implemented with care.
Scientists say the key job of the concrete channel, which has featured in countless films and pop videos, is to protect the city from damaging floods.
And that role is likely to become more challenging if climate change brings heavier rains, they argue.
Alternatives to the river's current brutalism will not be easy to find.
"This is not a simple...
Most of Alaska’s Permafrost Could Melt This Century
Posted by LiveScience: Tia Ghose on December 19th, 2014
LiveScience: The permafrost in some of Alaska's most iconic national parks could all but disappear this century, new research suggests. Right now, half of the ground in Denali National Park's is frozen year-round, but if global warming continues at the current pace, just 1 percent of this land could remain permafrost by the year 2100, according to new research presented here at the annual meeting of the American Geophysical Union. Not only could vast swaths of the Alaskan tundra transform into swampy bogs,...

Posted by Environmental News Network: AlphaGalileo on December 19th, 2014
Environmental News Network: There are consequences of the successful efforts worldwide to save beavers from extinction. Along with the strong increase in their population over the past 100 years, these furry aquatic rodents have built many more ponds, establishing vital aquatic habitat. In doing so, however, they have created conditions for climate changing methane gas to be generated in this shallow standing water, and the gas is subsequently released into the atmosphere. In fact, 200 times more of this greenhouse gas is released...

Posted by Washington Post: Juliet Eilperin on December 19th, 2014
National Geographic: Now that oil prices have dropped to levels not seen since 2009, helped by a flood of oil flowing from hydraulic fracturing or fracking wells in North Dakota and Texas, it's time to ask the question: How long can the U.S. oil boom last?
In the short term, the price drop threatens profits from fracking, which is more expensive than conventional drilling. Sure enough, permit applications to drill oil and gas wells in the U.S declined almost 40 percent in November.
But in the long term, the U.S....
Extremes concern as planet gets hotter and colder
Posted by Climate News Network: Tim Radford on December 19th, 2014
Climate News Network: Global average temperatures continue to rise, but new research shows that the extremes of heat and cold are rising even faster.
Scientists report that heat waves have got hotter and cold snaps have got colder at a more extreme rate – and that continuing greenhouse gas emissions will mean that, in another two decades, Europe could experience once every two years the sort of lethal heat waves that occurred once in a thousand years.

Permafrost thaw threatens Arctic infrastructure
Posted by Deutsche Welle: None Given on December 19th, 2014
Deutsche-Welle: Global warming is changing the Arctic - while some herald the opportunities that come with easier access, the thaw could literally yank the ground out from under communities. DW talked to an expert about the risks.
DW: Why should we be concerned about warming and thawing in the Arctic?
Hugues Lantuit: Permafrost is frozen ground in the Arctic, and it's currently warming at a fast pace. What we've done in a European Union project is to build for the first time an integrated database on permafrost...
Most of the coastal US will see over 30 days of flooding due to sea level rise
Posted by Huffington Post: Kate Sheppard on December 19th, 2014
Huffington Post: Most coastal regions of the United States will see 30 or more days of flooding by 2050 thanks to sea level rise, according to new research the National Oceanic and Atmospheric Administration released Thursday.
NOAA's researchers looked at the anticipated frequency of what the National Weather Service considers nuisance flooding, which are floods that are 1 to 2 feet over the regular local high tide and are enough to cause problems but not pose active threats to human life. Some areas of the U.S....

Posted by Business Times: None Given on December 19th, 2014
Business Times: Clearing of trees in tropical rainforests not only increases carbon dioxide in the air but also affects rainfall patterns and raises temperatures across the globe, says a study showing that forests have many impacts on climate. This in turn could adversely affect agricultural productivity. A complete tropical deforestation could lead to a rise in global temperature of 0.7 degrees Celsius (on top of the impact from greenhouse gases). The study from the University of Virginia in collaboration with...
