First Published on Truthout, August 27, 2014 (link) The fundamental climate change policy question today is not how much we should reduce carbon dioxide emissions by when, but what will currently proposed carbon dioxide emissions reductions do to our climate in the near-term? In addition, what are the ramifications of short-lived climate pollutants that are discounted by the traditional long-term 100-year climate policy time frame?

Remember, average global warming over land is double the global average because of the cooling influence of our oceans and ice sheets, or 3.56 degrees C in December (6.4 F). and the average over the arctic is four times the global average or 7.12 C (12.8 F). Importantly, the increase in extreme temperature is far greater than the average, and extreme weather increases nonlinearly because of the basics of heat and energy physics, where a little warming does not create a little more extremeness in the weather, it creates a lot more.
