Climate Change Action and Need

The International Energy Agency has issued another major report warning that we are headed for a beyond-catastrophic 11°F warming (6°C). The IEA report, “Energy Technology Perspectives," explains that delaying climate action has cost the world trillions of dollars in just the past two years.[read more]

El Niño Chances Jump To Near 80%, Add In Global Warming And We Face Record Heat

May 13, 2014 by Joseph Romm

Weather Patterns and Warming Trends

The chances of an El Niño developing this year are now at almost 4 out of 5. The chart above from NASA makes clear El Niños are generally the hottest years on record — since the regional warming adds to the underlying man-made global trend.[read more]

Climate Change and Foggy Ideas

 

It is mind blowing that the world’s financial capitals, most of which exist at sea level, so willfully finance the extraction and refinement of the instruments of their own demise while at the same time beggaring the only approaches that have demonstrated potential to safeguard them.[read more]

IPCC Prognosis: 9°F Warming For US, Faster Sea Rise, Extreme Weather, Permafrost Collapse

October 1, 2013 by Joseph Romm

IPCC Report and Risks

Perhaps the best way to think about the IPCC, which has issued a summary of its latest report reviewing the state of climate science, is as a super-cautious team of brilliant diagnosticians and specialists who, like many doctors, aren’t the greatest communicators.[read more]

Demand Response and Summer Heat

What happens to your normally cool household when you get paid $1.25/kwh to provide real-time demand response, and it's 97 sweltering degrees outside? Read on to find out about my adventures in demand response over the summer.[read more]

Global Temperature Change: Targeting Two Degrees

August 5, 2013 by David Hone

There is now something of a religious fervor around the goal of 2°C, to the extent that it is almost impossible to discuss other trajectories or outcomes. The only contrast that seems possible with 2°C is something that nobody wants, the “do nothing” scenario of 4°C.[read more]

NOAA: Second Hottest May On Record Globally, Hottest For Northern Hemisphere

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]

Two more independent studies back the Hockey Stick: Recent global warming is unprecedented in magnitude and speed and cause

September 21, 2010 by Joseph Romm

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]

2C or not 2C: Copenhagen and global temperature threshold (Part 1)

December 14, 2009 by Simon Donner

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]

The challenge of agreeing on degrees

July 11, 2009 by Simon Donner

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]

Must-read NOAA paper smacks down the deniers: Q: “Is there any question that surface temperatures in the United States have been rising rapidly during the last 50 years?” A: “None at all.”

July 7, 2009 by Joseph Romm

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]

Gloomy outlook from BT/Independent's SustainIT forum

April 1, 2009 by David Tebbutt

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]
