good luck to them...but I was thinking of the AGU - the American Geophysical Union.
I am pretty sure I addressed this in another thread, however, to the point of the AGU, another of those groups I pay little attention to, while I agree that man has a certain influence on the environment, and thus the climate, I dis agree that it is the major problem. We have underwater volcanoes (the Ring of Fire) erupting quite often, and spewing out methane gas. Whether or not that is caused by mans actions is questionable. Man himself is destroying the environment with his industrial actions such as cutting down the rain forests for the timer, oil, or gold. This in turn affects the weather patterns, and the filtering of the air. Then we have the garbage being dumped into the oceans affecting the temperature of the water, and the acidity. On land we have man using fertilizers, pesticides, herbicides, (and then the amount of medicines, and cosmetics found in ground water, or streams, is phenomenal.) polluting the water, the air, and the food we eat.
I once wrote a paper in which I asked the question "does anyone have any idea as to what effect the paving of highways, the carving out of tunnels, the the building of skyscrapers, dams, houses, etc. has had on the environment?". No one has an answer, yet the effects can be seen.
Iti si not that man has an effect that I disagree with, it is the amount that I question, and have seen no proof that man is anymore hazardous then nature. Man can be controlled though, and can change his effect. Little we can do about nature.
