Global warming and the California wildfires

Global warming makes wildfires more likely and more destructive -- as many scientific studies have concluded. Why? Global warming leads to more intense droughts, hotter weather, earlier snowmelt (hence less humid late summers and early autumns), and more tree infestations (like the pine beetle). That means wildfires are a dangerous amplifying feedback, whereby global warming causes more wildfires, which release carbon dioxide, thereby accelerating global warming.

The climate-wildfire link should be a special concern in a country where wildfires have burned an area larger than the state of Idaho since 2000.

I write this as my San Diego relatives wait anxiously in their hotel room to find out if their Rancho Santa Fe home has been destroyed. This is a beautiful home that I lived in for a month when I moved to the area in the mid-1980s to study at the Scripps Institution of Oceanography.

Can we say that the brutal San Diego wildfires were directly caused by global warming? Princeton's Michael Oppenheimer put it this way on NBC Nightly News Tuesday:

The ocean carbon sink is saturating

The long-feared saturation of one the world's primary carbon sinks has apparently started. The BBC reports, "The amount of carbon dioxide being absorbed by the world's oceans has reduced."

After 10 years and more than 90,000 ship-based measurements of CO2 absorption, University of East Anglia researchers reached this stunning conclusion:

CO2 uptake halved between the mid-90s and 2000 to 2005.

The BBC writes: "Scientists believe global warming might get worse if the oceans soak up less of the greenhouse gas."

Sigh. Note to the BBC, you don't need a double hedge: If you're going to just say "might get worse" you surely can drop "Scientists believe." Frankly I doubt you can find many, if any, reputable scientists -- or even the few remaining deniers -- who would say that if the ocean sink saturates, global warming won't get worse. I would probably phrase it this way: Global warming will accelerate if the oceans soak up less of the greenhouse gas.

The researchers say, "it is a tremendous surprise and very worrying because there were grounds for believing that in time the ocean might become 'saturated' with our emissions -- unable to soak up any more."

Why is that bad news?

CLEAN calls for action on energy policy

Well, they dropped a bundle to get a quarter-page "Clean Power" ad in the Washington Post (page A21 today) so the least I can do is give them a shout out here.

CLEAN is a "clean power and coalfield state grassroots organization" circulating a comprehensive national "call to action" on energy policy that includes:

Your chance to get in on the hydrogen action

Treehugger reports on a public bet I have made with Greg Blencoe, CEO of Hydrogen Discoveries:

Greg Blencoe wins if hydrogen fuel cell vehicles hit 1% of new sales of the typically-defined car and light truck market in the U.S. during 2015 or any year before. Joseph Romm wins if it is 2016 or any year after.

At stake is $1000, plus a certain amount of pride (if I lose, I must be photographed wearing a t-shirt saying "I was wrong about hydrogen.")

I am certainly prepared to make that bet with pretty much anyone -- though I might have to reconsider in the (very) unlikely event I get too many takers. Reasons why you shouldn't take the bet are below:
