Walruses Again Being Forced Ashore as Arctic Sea Ice Retreats

Published by Nick Sundt on Mon, 08/30/2010 - 19:56

An animated map from the U.S. Geological Survey shows the daily locations of tagged walruses and sea ice distribution in the Chuckchi sea. As the extent of Arctic sea ice again declines to one of the lowest levels on record -- especially off the coast of Alaska -- watch the walruses congregate on the remaining ice and increasingly in "haul outs" along the Alaska shoreline.

The Pacific Walrus says: "The time has come...We have many things to talk about, people!"

In what she modestly calls a "doodle," talented writer and illustrator Karen Romano Young captures the plight of the Pacific Walrus as it faces a decline in vital Arctic sea ice. "The walrus, some say, could be as much a poster child for the effects of climate change as its compatriot, the polar bear," says Young.

Sea Ice Extent Far Below Previously Recorded Levels in Northern Route of Northwest Passage

"[T]oday’s conditions in the Northwest Passage would likely astonish 19th century explorers," reports the National Snow and Ice Data Center. Overall, the center reports that as Arctic sea ice approaches its September minimum, sea ice extent is 649,000 square miles below average.

Video: Climate Change, Ocean Acidification and the Arctic Ocean

With the extent of Arctic sea ice presently at the second lowest level on record for the date, we are reminded of the growing threats to the Arctic ocean posed by rising atmospheric greenhouse gas concentrations. Here is nice video overview from actor Ted Danson and the organization, Oceana.

NOAA Joins NASA in Declaring that July 2010 was Warmest on Record for Northern Hemisphere

Published by Nick Sundt on Mon, 08/16/2010 - 11:56

The National Oceanic and Atmospheric Administration (NOAA) has released climate data for July 2010 confirming what NASA data separately found last week: it was the warmest July on record for the Northern Hemisphere.

NASA Polar Ice Expert on Climate Change and Greenland's Ice Loss: "We Need to Take this Seriously"

Published by Nick Sundt on Fri, 08/13/2010 - 12:30

On MSNBC's Countdown, Keith Olbermann on 9 August 2010 interviewed NASA polar ice expert Dr. Jay Zwally about the ice island that broke off of Greenland last week. Zwally said that it was 100% certain that climate change was a factor in the event.

Northern Hemisphere Temperature Shatters July Record

Published by Nick Sundt on Wed, 08/11/2010 - 18:02

NASA released data today (11 August 2010) showing that the average surface temperature in July 2010 in the Northern Hemisphere shattered the previous record set in 2005. Globally, the year to date is the warmest on record (i.e. in 131 years).

Arctic Sea Ice in July is Second Lowest on Record, Maintaining Rapid Longer Term Decline

Published by Nick Sundt on Sun, 08/08/2010 - 17:24

The National Snow and Ice Data Center reports that the extent of Arctic Sea Ice has dropped to the second lowest level on record, second only to 2007.

Greenland Glacier Calves the Arctic's Largest Ice Chunk in Nearly a Half-Century

Published by Nick Sundt on Sun, 08/08/2010 - 10:15

One of the largest of Greenland's marine "outlet" glaciers (i.e. glaciers ending in the sea) has calved an enormous "ice island" that reportedly extends over 100 square miles. Not since 1962, when a 250 square mile island was formed from the Ward Hunt Ice Shelf, has such a large area of ice been calved in the Arctic.

2010 Now Tied With 2007 For Number of Countries Breaking All Time High Temperature Records

Published by Nick Sundt on Mon, 08/02/2010 - 11:55

With Cyprus reaching its all-time record high temperature of 46.6°C (115.9°F) on 1 August 2010, fifteen national high temperature records now have been broken this year. Among the countries breaking records in July was Russia where anomalous heat in both the West and Northeast has created extreme wildfire conditions.
