amazed at how hot the summer has been compared to 20 years ago. Many are getting air conditioners when they never needed them before. Increased heat due to global warming. Wanted to move back to the cool Olympic Peninsula after 20 years dealing with heat and humidity in the D.C. area. Surprised at how hot it has been and my plants look sad. We never needed air conditioning before and sure do now, and we have to water the lawn, which we never had to do before. Is our zone changing?
Here is information from authoritative sources on global warming that you should find interesting.
