Well, not my model exactly. I developed and host a web interface to the modtran model of atmospheric infrared radiation, an early example of a line-by-line code which I downloaded and use to teach and as part of a textbook. Now David C. Archibald from Summa Development Limited, Perth, WA, Australia claims that my “University of Chicago modtran facility” proves that global warming won’t happen.

Thin Soup and a Thin Story
) (
) A firm called planktos.com is getting a lot of airplay for their bid to create a carbon offset product based on fertilizing the ocean. In certain parts of the ocean, surface waters already contain most of the ingredients for a plankton bloom; all they lack is trace amounts of iron. For each 1 atom of iron added in such a place, phytoplankton take up 50,000 atoms of carbon. What could be better?

Avery and Singer: Unstoppable hot air
Last week I attended a talk by Dennis Avery, author with Fred Singer of Unstoppable Global Warming Every 1500 Years (there is a summary here). The talk (and tasty lunch) was sponsored by the Heartland Institute, and was apparently enthusiastically received by its audience. Still whoozy from a bit of contention during the question period, a perplexed member of the audience told me privately that he thought a Point/CounterPoint discussion might be useful (he didn’t know I wrote for realclimate; it was just a hypothetical thought). But here’s my attempt to accommodate. [Read more…] about Avery and Singer: Unstoppable hot air
How much CO2 emission is too much?
) This week, representatives from around the world will gather in Nairobi, Kenya for the latest Conference of Parties (COP) meeting of the Framework Convention of Climate Change (FCCC) which brought us the Kyoto Protocol. The Kyoto Protocol expires in 2012, and the task facing the current delegates is to negotiate a further 5-year extension. This is a gradual, negotiated, no doubt frustrating process. By way of getting our bearings, a reader asks the question, what should the ultimate goal be? How much CO2 emissions cutting would it take to truly avoid “dangerous human interference in the climate system”? [Read more…] about How much CO2 emission is too much?
Rasslin’ swamp gas
In the early 1990’s, in defiance of IPCC projections, the methane concentration in the atmosphere abruptly stopped rising, and has remained nearly constant since then. Methane is a crouching tiger in the carbon cycle, with potentially enough available as hydrates and from peats to really clobber the Earth’s heat budget. The big question is, will atmospheric methane start rising again? [Read more…] about Rasslin’ swamp gas
Buying a stairway to heaven?
Just in the last year or so, a new type of scheme for reducing personal carbon emissions has appeared, the remarkably painless purchasing of “carbon offsets”. Carbonfund.org claims to neutralize a person’s CO2 footprint on the Earth for the low, low price of $99 per year, plus if you act now they will throw in an extra 5 tons for free! And you get a pen! Prices listed here range from $5-30 per ton of CO2 from a variety of similar organizations around the world. The average U.S. citizen is responsible for about 20 tons of CO2 release per year.
Compliance with Kyoto, a mere 5% reduction in carbon emissions, was forecast by Nordhaus [2001] to cost a few percent of GDP globally. The cost to stop emission completely and immediately may not even be calculable. Carbonfund.org promises zero net emissions, for a fraction of 1% of the average U.S. income. Can this possibly be real, or are we talking indulgences and snake oil?

Positive feedbacks from the carbon cycle
Two papers appeared in Geophysical Research Letters today claiming that the warming forecast for the coming century may be underestimated, because of positive feedbacks in the carbon cycle. One comes from Torn and Harte, and the other from Scheffer, Brovkin, and Cox. Both papers conclude that warming in the coming century could be increased by carbon cycle feedbacks, by 25-75% or so. Do we think it’s time to push the big red Stop the Press button down at IPCC? [Read more…] about Positive feedbacks from the carbon cycle
Incurious George
George Will argues now that no one would have noticed the 0.6 deg. C of global average warming to date, if the irresponsible press had not deliberately produced anxiety by pointing it out. He could be right. I expect no one would have personally noticed the ozone hole either. My grandmother smoked like a chimney and lived to be almost 100. If that nasty press had not deliberately stoked my anxieties about cigarettes and lung cancer, I would never have figured out the connection based on my personal experience. George argues that big crusading journalism is the problem. Ignorance is strength, right, George?
And, oh yeah, the global cooling stories, which appeared 30 years ago in the main-stream press (not the scientific literature). Shall we compare this with Will’s deliberate and repeated distortion of a real warning emerging from the scientific enterprise, continuing to the present day?
He looks like such an earnest man. I just don’t get it.
James Lovelock’s Gloomy Vision
James Lovelock, renegade Earth scientist and creator of the Gaia hypothesis, has written a gloomy new book called “Revenge of Gaia”, in which he argues that we should be stashing survival manuals, printed on good old-fashioned paper, in the Arctic where the last few breeding pairs of humans will likely be found after a coming climate catastrophe. The book is not published in the U.S. yet, but it is available from amazon.co.uk. Lovelock has never been one to shrink from a bold vision. What is it he sees now?
Wall Street Journal Again
The Wall Street Journal has published another fair and balanced critique of climate change science and negotiations, in a Business World commentary by Holman W. Jenkins, Jr, here. A summary of the arguments is as follows:
1. It will never be possible to prove that global warming is real. In the same way, we point out, it will never be possible to prove that anybody died from lung cancer because of smoking. Did you actually witness that first DNA mutation?
2. The reasonable lay person cannot be expected to read a scientific paper, so the rational response is to ignore the issue.
3. A paper about frogs did not argue convincingly that people cause global warming.
4. People sometimes distort the truth (truly a shocking charge coming from the WSJ).
5. Global change negotiations are stalled in politics, so the science must be wrong.
Final thought: When climate does change, we’ll be able to fix it anyway.
