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.

Report on international emissions inventories compares apples and oranges

Published by Ivan Dario Valencia on Thu, 08/12/2010 - 15:51

The Government Accountability Office finds that inventories from high-emitting developing countries need to be improved for any future agreement to curb emissions. What it doesn't mention is that such improvements are already underway.

The World Meteorological Organization on "Unprecedented sequence of extreme weather events"

Published by Nick Sundt on Thu, 08/12/2010 - 13:18

The World Meteorological Organization (WMO) issued a statement yesterday (11 August 2010) saying that "the sequence of current events matches IPCC [Intergovernmental Panel on Climate Change] projections of more frequent and more intense extreme weather events due to global warming."

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).

As Atlantic Hurricane Season Ramps Up, Radio Audiences Hear About Hurricanes and Climate Change

Published by Nick Sundt on Mon, 08/02/2010 - 19:20

With the Atlantic hurricane season poised for its usual August escalation -- and less than 24 hours before Tropical Storm Colin formed in the Atlantic -- Greg Holland, Director of the Earth System Laboratory at the National Center for Atmospheric Research, yesterday (2 August 2010) discussed hurricanes and climate change with radio stations around the country.

In "State of the Climate" Report, Scientists from All Continents Confirm that Climate Change is Underway

Published by Nick Sundt on Wed, 07/28/2010 - 17:34

"When we follow decade-to-decade trends using multiple data sets and independent analyses from around the world, we see clear and unmistakable signs of a warming world,” says Dr Peter Stott, contributor to the report.

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

Published by Nick Sundt on Thu, 07/15/2010 - 11:10

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.

Rising Greenhouse Gas Concentrations Driving Up Sea Surface Temperatures that Fuel More Intense Hurricanes

Published by Nick Sundt on Mon, 07/12/2010 - 10:34

Hurricane expert Greg Holland of the National Center for Atmospheric Research says the potential for a disastrous 2010 hurricane season reflects not just natural variability but also climate change. He explained that record high sea surface temperatures in the tropical Atlantic were one of the principal factors behind the dire forecast, and that rising atmospheric concentrations of greenhouse gases may account for roughly half of the anomolous warmth. He warned that "we’re looking at potentially a doubling of major hurricanes in the next 20 to 30 years" as a result of global warming.

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

Published by Nick Sundt on Fri, 07/09/2010 - 14:26

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.

Bill to slash Amazon protection passes crucial vote
