A few months ago, I posted a piece, based on interviews with leading permafrost experts, that pushed back, hard, on the “we’re all gonna die and there’s nothing we can do” catastrophism around the so-called “methane bomb” in the arctic. (I’ll repost that one below if you have not seen it)

That’s not to say that we don’t have a problem. When people tell me that the world is about to end, my response is that we’re not getting off that easy.
Above, more from the same researchers, looking at a little more fine grained data from the permafrost – and observations of a phenomenon that is coming into sharper focus.
As the planet warms, permafrost is softening, causing microbes to awaken and begin feeding on the organic matter therein – releasing more CO2 and methane. Good enough – but a lot of folks don’t understand that THAT process alone is not a world breaker – in fact, as more vegetation springs from softened permafrost, photosynthesis is kicking in – carbon is being stored, and in some models, actually sequestering more carbon.

The more pressing issue coming into focus is that the permafrost does not melt uniformly, and tends to collapse here and there into thousands, maybe millions, of lakes – that break through the surface “active layer” of the permafrost, and into the reservoir of more deeply stored carbon.
These lakes are hot-spots of carbon and methane release, and could add substantially to the total output in coming centuries.
It’s not the sudden catastrophic impact of disaster movies, but, as one of the experts, Katey Walter Anthony, told me, “..it’s a strong headwind.”

Flogging the Scientists

March 15, 2010

As a nonscientist, it’s daunting for me to work thru the huge volume of information on global climate change. I’ve found that the most reliable scientific information comes from respected peer reviewed science journals .

But journals have lots of big words, and lots of small print, and very few illustrations to make it easy for me. You can see why climate deniers don’t like them. But that’s where the facts are.

How can you tell a good science journal?

Birth of a Crock

October 6, 2009

The observation that natural climate variability exists is not a new one.

Early in September 2009, at a gathering of experts on global climate change, one of the world’s most respected and experienced climate modelers, Mojib Latif, made some observations on climate, media and human nature.

The message seemed clear-
natural variations in the long term warming might be misinterpreted
by the media. out of ignorance, or malice.

Climate deniers were quick to take Latif’s remarks, and begin
doing exactly that.

One of the enduring myths of climate denialism is that global warming stopped sometime in the last decade. I see it in the blaring headlines of pseudoscience websites, in comments on my videos, even some of our most “distinguished” journalists have been taken in.
