0 A few more comments

I'm still in 'run around' mode, but did catch up with some good comments to the blog. New comments in:

• Semi-open thread (and I can't answer the CO2 one offhand -- too many different things showing up in the literature. I'll have to do some focused reading.)
• The Central Skill of a Scientist
• Sea Ice Odds
• Results on deciding trends

Worth a look.
