Warming up to the Warming World MOOC

I thought I'd try out the World Bank's Warming World MOOC and it's going well. As a four-week course I thought it might be too basic, even for a non-scientist, but Week 1 had some new-to-me items as well as fine tuning what I generally knew (e.g., current CO2 are the highest not in 3-5 million years as I thought, but 15 million years).

In the new-to-me category, food production in both India and Africa can be strongly, adversely affected by high heat - I thought the food-security issue was primarily about precipitation changes. Climate change can kill a lot of poor children in yet another way that I didn't know.

Other new thing - what the heck's the matter with Luxembourg?

Its 2009 and 2010 per capita emissions are worse than  Canada, Australia, and the US. That's just embarassing. Get a grip!

Anyway, the course seems worth checking out. I'm too lazy to do the essay portion though so no certificate for me.
