The Earth’s northern polar region will be almost ice-free in the warmest months by 2050, sooner than previously estimated, according to a study by two federal government scientists who work on climate change. ... read more >>
White House warned on imminent Arctic ice death spiral | Nafeez Ahmed | Environment | guardian.co.uk
The melting of sea ice in the Arctic has caught the eye of the US Department of Homeland Security and the Pentagon. ... read more >>
Observations, whether from satellites, sensors, or from people who live in the Arctic tell the same story – the Arctic climate is changing faster and more severe than most of the rest of the world. The Arctic is warming at a rate of almost twice the global average. See Video on the post for feeling changes in arctic ice melting! ... read more >>
Sea levels have risen along the East Coast around 6 to 8 inches since 1960. Under different global warming scenarios, seas could rise 8 inches to several feet by 2100.
The longer term concern is that if warming causes the collapse of the Greenland and/or Antarctic ice sheets, seas could rise tens of feet, although it is thought a rise of that magnitude would take hundreds of years.

Global warming is the primary factor contributing to rising sea levels and with new data showing that greenhouse gas emissions continue to rise, we can expect concomitant rises in sea levels in America and around the world. To try to address the threat on the US East Coast, UCS convened a multi-state roundtable in April. This roundtable included the US Army Corps of Engineers as well as officials ... read more >>
On the sixth-month anniversary of superstorm Sandy, NBC evening news looked at whether rising seas and ever-worsening storms could destroy beach living.
Of course the answer is that it could and probably will on our current emissions path:
NBC: “The three feet of sea level rise predicted by the end of the century could swamp the jersey shore and redraw the coastline of florida. more imm ... read more >>
Glacial ice in the Peruvian Andes that took at least 1,600 years to form has melted in just 25 years, scientists reported Thursday, the latest indication that the recent spike in global temperatures has thrown the natural world out of balance.
The evidence comes from a remarkable find at the margins of the Quelccaya ice cap in Peru, the world’s largest tropical ice sheet. Rapid melting there ... read more >>
Recent studies have identified a "hot spot" of accelerated sea level rise from Cape Hatteras, N.C., to Boston, and researchers have speculated that a diminished flow of the Gulf Stream might be partly to blame. Now, data analysis by a team of oceanographers led by Tal Ezer of Old Dominion University has given that hypothesis new scientific footing.
The team's findings were published in January ... read more >>
For a political candidate, being labeled a “flip-flopper” can be a career killer. Just ask Secretary of State John Kerry, who lost his 2004 presidential race in part because of his reputation for voting against bills before he voted for them. Increasingly, though, the label also applies to North American weather, which has been lurching from one extreme to the next in a pattern that is consistent ... read more >>
Most discussions of global warming focus on the temperature of the air at the Earth’s surface, where over the past decade warming has slowed. This has resulted in misleading declarations that global warming has "paused." However, failing to consider the heating of the oceans misses the bulk of global warming. Global warming hasn't paused, it's accelerating, especially in the oceans, according to ... read more >>
