NOAA – Second hottest September on record

NOAA’s National Climatic Data Center has issued its latest monthly, “State of the Climate: Global Analysis,” which found: The combined global land and ocean surface temperature for September 2009 was 0.62°C (1.12°F) above the 20th Century average of 15.0°C (59.0°F). This was the second warmest September on record, behind 2005, and the 33rd consecutive September […]

No, I’m not taking about a simple analysis of what happens […]

Must-read NOAA paper smacks down the deniers

The […]

I thought about this on my bike ride to work this morning when the smell of exhaust from cars seemed more potent, and the fumes were certainly more visible in the 32-degree air. I know that air quality in Los Angeles is worse during […]
