I think the focus on regional effects is a good one because people relate to them much more easily. Today there is also a great article in the NYT on climate change in Yellowstone. It talks about snowpack, drought, and invasive species of weeds and bugs that are more prevalent because of shorter warmer winters. That kind of specificity hit home for me living in the Midwest. In the past few years our ash trees were ravaged by the Emerald Ashbore and just this year a horribly difficult weed, the yellow nutsedge, began spreading. Both of these are new in our area because of warmer temperatures.
