Environmental Defense: Global Warming Science — Ten Top Stories of 2007
This post is by Lisa Moore, Ph.D., a scientist in the Climate and Air program at Environmental Defense.
All year long we’ve been monitoring developments in climate science, and posting about the important new developments. I thought now would be a good time to look back over 2007 and summarize what we’ve learned.
Here are ten noteworthy science stories we covered in 2007:
1. The Sun is (really, really) not responsible for global warming. This paper wasn’t breaking news, just an extremely thorough review of the science showing why the sun can’t be blamed for global warming. The folks over at RealClimate said it best: “That’s a coffin with so many nails in it already that the hard part is finding a place to hammer in a new one.”
2. American Southwest climate is becoming drier. Global warming has caused a long-term shift in rain patterns. An author of the study said, “You can’t call it a drought anymore, because it’s going over to a drier climate. No one says the Sahara is in drought.”
