Climate change redistributes global water resources
Posted by Washington Post: Juliet Eilperin on March 14th, 2016
PhysOrg: Analysis of more than 40 years of water samples archived at the Hubbard Brook Experimental Forest (HBEF) in New Hampshire tells a vivid tale of how the sources of precipitation have changed. Over the years, there has been a dramatic increase, especially during the winter, of the amount of water that originated far to the north.
"In the later years, we saw more water derived from evaporation of the Arctic and the North Atlantic oceans," said Tamir Puntsag, a graduate student at the SUNY College...

Degrading underground ice wedges are reshaping Arctic landscape
Posted by Washington Post: Juliet Eilperin on March 14th, 2016
ScienceDaily: Rapid melting of ice and Arctic permafrost is altering tundra regions in Alaska, Canada and Russia, according to a new study released in the journal Nature Geoscience. Ice-wedge degradation has been observed before in individual locations, but this is the first study to determine that rapid melting has become widespread throughout the Arctic.

Zero carbon emissions target to be enshrined in UK law
Posted by Guardian: Motorway Traffic Jam The Uk Is Already Committed To Reducing Carbon Emissions 80 on March 14th, 2016
Guardian: The UK will enshrine in law a long-term goal of reducing its carbon emissions to zero, as called for in last year’s historic Paris climate deal.
Responding to former Labour leader Ed Miliband’s call to put the target into law, energy minister Andrea Leadsom told parliament on Monday: “The government believes that we will need to take the step of enshrining the Paris goal for net zero emissions in UK law. The question is not whether but how we do it.”
The UK is already legally bound by the Climate...
Salmon farmers’ shares rise as Chilean algal bloom boosts prices
Posted by Reuters: Felipe Iturrieta on March 14th, 2016
Reuters: An algal bloom in Chile that has killed up to 20 percent of the nation's farmed salmon has sent shares of producers higher as the reduced supply has lifted selling prices.
Over the last month and a half, salmon farmers in Chile, the second-largest global producer after Norway, have been hit by production losses of around 100,000 tonnes, worth some $800 million, according to industry experts.
The drop in supply from Chile caused global prices last week to rise 25 percent to $5 per pound in Miami,...
As U.S. Coastal Cities Swell, Rising Seas Threaten Millions
Posted by Climate Central: John Upton on March 14th, 2016
Climate Central: A growing number of Americans are moving into homes nestled between the idyllic beaches of the Florida Keys -- part of a national trend that's seeing coastal populations swell even as the seas swell dangerously around them.
That combination of rising populations and rising seas could see millions of Americans living in homes that flood regularly during the decades ahead, according to a nationwide analysis published Monday in the journal Nature Climate Change.
That's unless steps are taken to...
Mississippi and Louisiana warily eye rising Pearl River
Posted by Christian Science Monitor: Eva Botkin-Kowacki on March 14th, 2016
Christian Science Monitor: Louisiana and Mississippi emergency officials nervously eye the rising Pearl River which runs along the border of the two states, as more rain is predicted for later this week.
Flooding began last week and has already damaged thousands of homes across the region and claimed at least four lives in Louisiana. In Mississippi, the hunt continued Sunday for two missing fishermen. And this isn't the first time the Pearl River has surged over its banks.
The National Weather Service predicts the river...
Study: Over 13 million coast-dwelling Americans at risk from rising sea levels

Mediterranean could be in driest spell for 900 years
Posted by Climate Home: Tim Radford on March 14th, 2016
Climate Home: The drought that has blighted the eastern Mediterranean since 1998 could be the worst in nine centuries, according to new research led by scientists from the US space agency Nasa.
They report in the Journal of Geophysical Research Atmospheres that they used a tree-ring chronicle – trees accurately reflect the rainfall conditions of each year in their annual growth – to establish what had happened.
They found that although the island of Cyprus and the bordering nations of Israel, Jordan, Lebanon,...
Global warming: Feb temperature rise ‘unprecedented’
Posted by Climate Home: Ed King on March 14th, 2016
Climate Home: February 2016 broke global temperature records, according to data released by NASA on Saturday.
Global surface temperatures were 1.35C above the 1951-1980 global average for the month, a development described by experts as "an ominous milestone towards a warmer planet."
"Perhaps even more remarkable is that February 2016 crushed the previous February record -- set in 1998 during the peak atmospheric influence of the 1997-98 super El Nino that`s comparable in strength to the current one -- by...
Indonesia warns of fire risk in haze-prone regions in March-April
Posted by Washington Post: Juliet Eilperin on March 14th, 2016
Reuters: Indonesia expects dryer than normal weather in several fire and haze-prone regions in western and central Indonesia in March and April, the state weather agency (BMKG) said on Monday, referring to a recent increase in fires and hotspots.
The region suffers every dry season from so-called haze caused by smoldering fires, often set deliberately to clear land for palm oil plantations on Sumatra and Borneo islands.
Fires were particularly bad in 2015 because of a prolonged dry season caused by...
