WASHINGTON — The northeastern U.S. coast is likely to see the world’s biggest sea level rise from man-made global warming, a new study predicts.
However much the oceans rise by the end of the century, add an extra 8 inches or so for New York, Boston and other spots along the coast from the mid-Atlantic to New England. That’s because of predicted changes in ocean currents, according to a study based on computer models published online Sunday in the journal Nature Geoscience.

California’s interagency Climate Action Team on Wednesday issued the first of 40 reports on impacts and adaptation, outlining what the state’s residents must do to deal with the floods, erosion and other effects expected from rising sea levels.

Hundreds of thousands of people and billions of dollars of Golden State infrastructure and property would be at risk if ocean levels rose 55 inches by the end of the century, as computer models suggest, according to the report.

SANTIAGO (Reuters) – Time is running out to save the world from the ravages of climate change and prevent economic meltdown and a flood of environmental refugees, Britain’s Prince Charles has warned on a visit to Chile.

The Prince of Wales, and his wife, Camilla Parker Bowles, are in Chile at the start of a Latin American tour to promote energy efficiency and measures to combat climate change.

MUCH has been written of late regarding the impending demise of the world’s coral atolls due to sea level rise.

Recently, here in the Solomon Islands, the sea level rise has been blamed for salt water intrusion into the subsurface “lens” of fresh water under some atolls.

HICKORY, Penn. (Reuters) – On a snowy hillside in rural southwest Pennsylvania, Larry Grimm drives his truck up a steep gravel track to a hilltop reservoir surrounded by orange plastic fencing and “keep out” signs.

The pond supplies water pumped from a local creek to the natural gas wells that are springing up throughout Mount Pleasant Township, where Grimm is the municipal supervisor.

A new international study has warned that millions of people dependent on fisheries in Africa, Asia and South America could face unprecedented hardship as a consequence of climate change.

Researchers examined the fisheries of 132 nations to determine which were the most vulnerable, based on the potential environmental impact of climate change, how dependent their economy and diet were on fisheries, and the capacity of the country to adapt.

Four miles south of the Arctic Circle, the morning sky is streaked with apricot. Frozen rivers split the tundra of the Seward Peninsula, coiling into vast lakes. And on a silent, wind-whipped pond, a lone figure, sweating and panting, shovels snow off the ice.

The young woman with curly reddish hair stops, scribbles data, snaps a photo, grabs a heavy metal pick and stabs at white orbs in the thick black ice.

Areas with lowland permafrost are likely to shrink in northern Sweden. Warmer summers and more winter precipitation are two of the reasons. This is shown in a new dissertation from Lund University in Sweden.

Permafrost is ground that is frozen year round at least two years in a row. North of the Arctic Circle permafrost is common due to the cold climate. For several years, physical geographer Margareta Johansson at Lund University has studied lowland permafrost in peat mires surrounding Abisko. Permafrost is on the edge of its range there. Johansson states that permafrost is being affected by climate changes.

While Europe may take better care of its water resources than other continents, it in fact uses larger quantities via imports of goods such as cotton, beans or wood, which often come from regions that already suffer from water scarcity, argues a UN expert in an interview with EurActiv.

The notion of “virtual water” embedded in a commodity or a product, is an essential part of the ‘water footprint’ theory but has not yet received much attention, argued Maude Barlow, a special adviser on water issues to the president of the UN General Assembly.
