2:1 odds that averaged global temp goes up instead of down in 10 years measured by USA National Climatic Data Center data.
Trusted third party holds the money in CDs. Winner takes it all, including interest. We could probably figure out someone here at HZ we both trust. I also have a charity bet offer we could use as the betting vehicle at longbets.org, but the site is down right now.
As for science not being about betting, you're partially wrong - see:

but mainly I wanted to just show, as was the case last time, that you won't put your money where your mouth is.
