I tend to stay out of climate change debates. This is my first time venturing into one of these threads. So please, dont jump me
My simplistic view- "Climate" is average weather over some time period. One accepted definition of a period over which we can assess climate for a given region, is 30 years, per the WMO. I believe the inference wrt to climate change is that the industrial age and associated pollution is influencing climate. If we look at the average daily high and low temps, average snowfall, etc for say DC, over the past 30 years, and then the 30 year period prior to that, and then again the 30 year period prior to that, what does the data show? I think everyone(or maybe not) acknowledges that we have polluted the planet over the past 100 years, so the only questions with regard to impact on climate should be to what extent and over how much time. I don't think we have these answers, thus the speculation and debate. What perturbs me are the people that couldn't do a simple heat balance calculation, professing to know anything about such things on a global scale. Unfortunately there is no way to separate ignorance, presumptuousness, and politics from the science.
