belated Earth Day

Here are a few interesting articles I found this past week:

• The Next Generation of Biofuels (Scientific American) and California Takes on King Corn (The Daily Climate) talk about alternatives to corn-based ethanol
• How to Fix a Climate Emergency (Newsweek) is a pretty interesting look at some radical ideas about slowing down global climate change (and it makes a good point about how this shouldn't be a replacement for cutting emissions)
• and Wil Wheaton found a cool video of Earth rising over the moon's horizon (must have been taken near new moon)
