NOAA has released its “State of the Climate Global Analysis” for May 2012. Here are the highlights:The combined global land and ocean average surface temperature for May 2012 was 0.66°C (1.19°F) above the 20th century average of 14.8°C (58.6°F). This is the second warmest May since records began in 1880, behind only 2010.The Northern...[read more]

Following fast on the heels of NASA reporting the hottest January to November on record — despite the deepest solar minimum in a century — NOAA’s National Climatic Data Center has released its State of the Climate: Global Analysis for November.  It finds this was the second warmest November on record (after 2004) and For the 2010...[read more]

There are now more studies that show recent warming is unprecedented –  in magnitude and speed and cause — than you can shake a stick at! As with a pride of lions, and a conspiracy of disinformers [or is that a delusion of disinformers?], perhaps the grouping should get its own name, like “a team of hockey sticks” (see “The Curious...[read more]

Media coverage of climate change often gives the impression the world’s scientific community all met and firmly established that the warming beyond +2 degrees C is dangerous to the future of society. The planet does not have one clear "dangerous" temperature threshold. Two things needs to be explained clearly. First, the definition of...[read more]

The Guardian has a report on climate forecasts for the coming century - Global temperatures could rise 6C by end of century, say scientists.Global temperatures are on a path to rise by an average of 6C by the end of the century as CO2 emissions increase and the Earth's natural ability to absorb the gas declines, according to a major new...[read more]

Andy Revkin has a nice short summary of the wisdom, or lack thereof, of pledging to avoid climate warming of 2 deg C or any other threshold beyond which climate disaster looms.The problem is that not only is there no one firm threshold, even if there were, there is no reason to think we could agree on it. Yes, the uncertainty in...[read more]

Nothing occupies global warming deniers more than trying to prove the U.S. temperature record — a tiny portion of the global temperature record — is not reliable.  Now NOAA’s National Climatic Data Center has issued an excellent Q&A, “Is the U.S. Temperature Record Reliable?” that should settle that question for any objective...[read more]

Yesterday's forum run by BT and the Independent was a culmination of a 'multi-channel media campaign' called SustainIT. The forum promised to 'explore the potential of ICT solutions to help businesses reduce their environmental footprint'. And it promised to talk about 'how to empower the developing world.'What it actually did was...[read more]
