This Global Warming Trend is due to a large increase in the amount of radiation (heat) blasted at us by the sun. Its a cycle. Ask yourself if a deficiancy in CO2 caused the little ice age. Ask yourself if too many camp fires caused the huge global warming spike before the little ice age. That spike was much higher than this one has reached. Ignore Gores propaganda piece and look straight at the evidence. You don't need someone to prey on your emotions. You need to see facts so you can make an informed decision. Never any disrespect directed to you or anyone else.
