The Countdown: 6/7/2011

POSTED BY: S. DOMAGAL-GOLDMAN
 
Sorry for missing yesterday. I had a good excuse. Honestly: 3… You see, I was at AbGradCon, the Astrobiology Graduate Conference. It’s a place where graduate students and early-career postdocs in astrobiology can get together inside a “closed ecosystem” that is free from the stresses imposed by the presence of established scientists. It’s a big part of the astrobiology community, and to be totally honest one of the major reasons I’m still in the field. I have many colleagues I....

But a paper last April claimed this wasn’t the case, and that carbon dioxide concentrations were no higher than modern-day values. The authors (Rosing, Bird, Sleep, and Bjerrum) solved the paradox with a cloud-free, ocean-covered Earth that was darker and absorbed more radiation. Well, today Nature....
