For years, the National Snow and Ice Data Center (NSIDC) has been sharing daily updates of the area (“extent”) of sea ice coverage in the Arctic ocean, charting current conditions in comparison to the 1979-2000 average for purposes of comparison. Current levels consistently lie two standard deviations below that long-term average, making the NSIDC Arctic [...]
Abrupt climate change in 1-2 years. The end of civilization. It’s not a movie. It’s a lecture by Prof. Paul Mayewski, and you can listen in. [...]
It may have been locally hot or cool where you live in the month of September, but globally speaking it was another scorcher. This week, NASA’s Goddard Institute of Space Science released its latest data on average global temperature to include measurements for September 2010 (data go back to January 1880). The Goddard Institute has [...]
The place for humans to inhabit would probably be along the planet’s zone of permanent dawn, where the rays of Glieselight are low enough to avoid causing excessive heat. Plants, if they’re edible, could grow to remarkable size in such conditions. [...]
Earlier this week, the University of Washington’s Polar Science Center released its latest Arctic sea ice measurements to make them current as of September 15, 2010. The Polar Science Center uses a satellite to measure the three-dimensional volume of the Arctic sea ice (a approach different than that of the National Snow and Ice Data [...]
The melting of the Arctic sea ice literally crossed another line yesterday, as the area of Arctic sea ice fell below the level of two years ago:
The collapse of the Arctic sea this year is only surpassed by the calamity of 2007. The four lowest years of Arctic sea ice extent are the [...]
Last week, the National Snow and Ice Data Center reported:
Arctic sea ice appears to have reached its annual minimum extent on 10 September. The minimum ice extent was the third-lowest in the satellite record, after 2007 and 2008, and continues the trend of decreasing summer sea ice.
But appearances can occasionally be deceiving. After [...]
This week, NASA’s Goddard Institute for Space Science released data on global temperatures for June, July and August 2010, the hot summer months in the Northern Hemisphere, where most people on the planet live. As summers go, boy, it was a hot one, and it wasn’t just hot where you live. Over land — where [...]
On Wednesday night, the National Oceanic and Atmospheric Administration (NOAA) released its National Climate summary of August 2010. Across the 48 continental United States, August 2010 was the 7th hottest August in the 116 consecutive years of U.S. temperature records. Not one of the 48 states that faced colder than normal temperatures in August 2010; [...]
As the summer progresses, I find myself waiting with interest for the arrival of some pieces of news. Here’s what I’m waiting for:
Section 527 quarterly financial reports. Most non-profit political organizations must file reports of their contributions and expenditures with the IRS on July 15 or July 20. With most reports filed electronically nowadays, [...]
2007-2008 marked the Fourth International Polar Year, a coordinated international research effort dedicated to a better understanding of the Earth’s poles. Various sorts of data were collected in more than 150 research projects during this year.
Some of this research is still proceeding, and a large amount of data collected during the International Polar Year [...]
