Is global warming caused by the sun?
What is responsible for most of the heat on the earth? If you said the sun, good for you.
Does the temperature on the sun vary? If you said yes, goog for you.
Are there solar flares that produce massive amounts of heat? If you said yes, good for you.
Is it possible and likely that a gradual increase in temperature of the sun could creat a gradual increase on earth? Once again good for you if you said yes.
Have scientists admitted that they do not fully understand solar flares and their effects? Once again....yes.
Should we send ALGORE to the sun to do his power point presentation and convince all of the residents of the sun that they are responsible for heating up the earth? Of course the answer is yes.
