Betting The Climate
Ronald Bailey | August 19, 2005, 2:55pm
I wrote about climate modeler James Annan's proposed bet on global warming earlier this summer. Now he's found some takers.
Annan, who works with the Japanese Earth Simulator supercomputer, has been trying to call out climate "skeptics" for a while and two Russian solar physicists, Galina Mashnich and Vladimir Bashkirtsev, have now ante'd up.
According to the Guardian:
To decide who wins the bet, the scientists have agreed to compare the average global surface temperature recorded by a US climate centre between 1998 and 2003, with temperatures they will record between 2012 and 2017.
If the temperature drops Dr Annan will stump up the $10,000...in 2018. If the Earth continues to warm, the money will go the other way.
Stay tuned: I'll be sure to report the winner in 2018.

"So none of the US skeptics were willing to do a 1-1 bet. I suppose this is because of the MASSIVE POWER of the INCREDIBLY RICH SIERRA CLUB or somesuch."
I offered James Annan ***50 to 1*** odds against the atmospheric methane concentration in 2030 exceeding 2060 ppb in the year 2030. (The value in 1990 was approximately 1700 ppb.) That 2060 ppb is the IPCC TAR ***midpoint*** value. So he should have been happy with even 50/50 bet. He refused...even at 50-to-1 odds.
I offered him ***25 to 1*** odds against worldwide industrial emissions of CO2 exceeding 13.2 gigatons as carbon. The emission value in 1990 was approximately 6.0 gigatons as carbon. The 13.2 gigatons as carbon is the IPCC TAR ***midpoint*** value. So he again should have been happy with a 50/50 bet. He refused...even at 25-to-1 odds.

On Long Bets, I have challenged ANY PRIMARY OR SECONDARY AUTHOR OF THE IPCC Third Assessment Report (there are over 700 of them) to bet that their prediction of the warming from 1990 to 2100 (midpoint as calculated by Wigley and Raper in Science) of 3.06 degrees Celsius will be more accurate than Michael Crichton's prediction of 0.81 degrees Celsius:

I later specifically extended that offer to William Connolley and Gavin Schmidt at "Real Climate". So far, absolutely NO TAKERS on a bet that a ***science fiction*** writer can more accurately predict warming in the 21st century, versus nearly 1000 scientists (or "scientists") using fancy-schmancy computer models. (Not to mention spending untold millions of dollars attending international meetings talking about those fancy-schmancy models.)
On Long Bets, I also challenged ANY IPCC PRIMARY OR SECONDARY author to bet that their predictions (sorry, "projections") in the IPCC Third Assessment Report would be more accurate than my own:

Not one taker.
P.S. I further made the following very generous Free Money Offer to James Annan and William Connolley. I offered to give them $8 for every IPCC Third Assessment Report author who would even be willing to VOTE against me on Long Bets #181. (The voting is free, and open to anyone.)

So far, they haven't taken me up on my Free Money offer. I also challenged them--offered to pay them, in fact--to make me a similar offer. They haven't.
The predictions (er, "projections") for methane atmospheric concentrations, human CO2 emissions and atmospheric concentrations, and resultant temperature increases in the IPCC Third Assessment Report constitute the greatest fraud in the history of environmental science.
I challenge anyone who says otherwise to debate me in the matter.
