Will forwarded this link to me. Thanks Will! It is a very interesting presentation about taking action against global warming. I encourage you to take a look and then to respond to what you see. I think he makes a very strong, compelling arguement which should be passed along to everyone, especially as I sit here with my windows wide open enjoying the 45 degree January weather.
However, you should also note that not everyone agrees with this perspective and the truth is the science behind global warming is incredibly complicated and in its infancy. You will need to make up your own minds about whether or not global warming exists. You do that by reading as much as you can and finding evidence for yourselves as to what the reality is.
