About 10 years ago Rush Limbaugh read a paper from some high falutin' dendronologist that unequivocally stated that we have substantially more forest today than we did 200 years ago. Nothing has changed.
The article is crap anyway, since outside of the urban cores, the climate is getting cooler fast.
Don't say that to those of us in Texas. Particularly Dallas, being an urban core. It's supposed to be around 95 degrees about this time of the year. My thermometer says 74 right now. Not that I'm complaining. I like the cooler weather.
