This is probably the last week our planet’s atmosphere will have less than 400 parts per million of carbon dioxide. When are we going to stop letting this heat-trapping waste gas pile up in our home?

Please. Please. Please. Please stop conflating weather and climate. It is cold today, yes, and that’s a big deal. But it doesn’t influence any scientific conclusion about climate change, one way or the other. Today’s cold temperatures are a weather event. It’s distinctive, but short-lived.

Check it out. Here’s a couple of things I was struck by: The annual variation between summer and winter ice cover …

In the interest of conveying a sense of the sort of stuff that goes on a large science conference like the AGU Fall Meeting, I’ll resume my narrative where I left off with yesterday’s description. I began by swinging by the press room where I grabbed a complimentary breakfast, then headed down to the “early earth” session where I got a review on zircons of Hadean and Archean age. Then …
