There is disagreement among scientists about whether there has been a permanent increase in temperature over the past few decades and whether contributions of so called greenhouse gases (GHGs) from human activities are causing changes in our climate. The basic global warming issue revolves around the effects of less than 1% of all atmospheric gases, mostly carbon dioxide and methane. Nitrogen and oxygen comprise 99% the earth’s atmosphere (Nitrogen--78.1%, Oxygen--20.9%), Argon--0.9%, Neon--0.002%, Helium--0.0005%, Krypton--0.0001%, Hydrogen--0.00005%, Water vapor--0 to 4%, Carbon Dioxide--0.035%, Methane--0.0002%, and Ozone--0.000004%.
The Center, founded in 1985, is an environmental organization dedicated to protecting the environment, enhancing human, animal and plant ecologies, promoting the efficient use of natural resources and expanding participation in the environmental movement.
