Seems to me that we have to live with it, whether anthropogenic or not. Clearly, bankrupting our economy on ridiculous false "solutions" won't help, but neither will ignoring a change just because it might be "natural."
Also, a better term would be "climate change" since it's generally not projected to be just a simplistic warming everywhere. Greater variability and extremes of weather is one of the characteristics that concerns me more than simple mean warming of air temperature.
Besides, based on past cycles, shouldn't we now be going into a cooler phase? If we're still getting warmer, then it's a deflection from "normal" and begs the question as to the cause.
I don't want a Mesozoic climate, even if it is only partly our fault. ;-)
The time scale point made by others is also very important. Where I am now (northern hemisphere, east coast USA), the sun is soon setting and it's getting colder each week. I see no global warming!
LOL! Wait for Spring...
