Being that the earth has been estimated to have been in existence for 4,600,000,000 years. And regional weather observations have only been recording since the mid 1800's (I think). How can we be sure that this current weather phenomena is man made and not due to similar solar activity which caused the Maunder Minimum or a cyclical phenomena similar to that which brought the ice age?
We can’t be sure that specific weather events are caused by climate change, just as we can’t be sure that a single case of lung cancer is caused by someone smoking. But we can look at trends, and we can look at the science, and even while there is argument about the extent of our role, no one doubts the greenhouse effect. I am not a climatologist, and I defer to the experts on this. A truly overwhelming majority are gravely concerned about our impact on the climate. For reasons I’ve already given, I think we’d be mad to ignore them.
