While it seems to minimize the human impact on
overall global climate change, it certainly does not absolve us from doing
everything we can to clean up our own back yard, or the air above
it.
Some fascinating reading is attached. One can see
the potential impact on our Forest lands.

This site: http://www.geocraft.com/WVFossils/ice_ages.html is
the best one I've seen to explain the geological, geophysical, and astrophysical
forces causing climate change. It is written in layman's terms and
contains many graphs and maps. They also note that humans are responsible
for only about 0.2% of greenhouse gases. Well worth the read.
