Do you feel lucky, Punk
The question is will the World end in 12 years if we all do not do exactly what Cortez the schizophrenic says......The question is not whether the climate would be changing without human action. As you have repeatedly condescendingly pointed out, although it had no bearing on the topic, it is trivially true that the climate is always changing.
But the evidence that the current climate change ... which (based on the geological record and on simple calculations about energy balance) is taking place at a rate that is extremely unusually rapid ... is caused by humans is plentiful, First, there is the known physical mechanism that ... if it is not causing accelerated greenhouse warming ... almost everything we know about physics, astronomy, and chemistry is wrong. Second, there is the fact that the current climate change was forecast in extremely accurate detail decades in advance, even though the forecast was for a huge departure from patterns that have held for hundreds or thousands of years. Third, there is the fact that no climate model that does not include anthropogenic forcings can be fit to the data.
