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

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"

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

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

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

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.

NOAA Reports Record Breaking Global Temperatures; Meltdown for Climate Change Denialists

The National Oceanic and Atmospheric Administration (NOAA) released data today (15 July 2010) showing that global temperatures in June -- and for the first six months of the year -- were the highest on record. As climate records continue to fall, attacks on climate science and scientists have been rebuffed by multiple investigations; and the National Academies of Sciences have solidified the scientific basis for action on climate change.

The Planet Feels the Heat as First Half of 2010 Sets Global Temperature Record

Global temperature data released today (9 July 2010) by NASA show that the first half of 2010 was the warmest January-June period in the 130 year record.  June was the warmest on record for the Northern Hemisphere, and tied in third place globally.

Average Arctic Sea Ice Extent Drops to Record Low for the Month in June

The National Snow and Ice Data Center reports that "[i]n June, ice extent declined by 88,000 kilometers (34,000 square miles) per day, more than 50% greater than the average rate of 53,000 kilometers (20,000 square miles) per day. This rate of decline is the fastest measured for June."
