There is very good hard science being produced that supports that global warming (and cooling) relate to solar activity and not CO2 in the atmosphere. One example is Environmental Effects of Increased Atmospheric Carbon Dioxide ARTHUR B. ROBINSON, NOAH E. ROBINSON, AND WILLIE SOON Oregon Institute of Science and Medicine. This is simply an issue of science. If you take the time to read and understand the science behind this issue, you will be hardpressed to continue to support the current global warming hypothesis (i.e. that increased CO2 is causing warming).
