The sun is the most significant contributor to the temperature on the planet earth. For now, this contribution seems stable, but in the past, the heat of the sun has fluctuated quickly. CO2 may be the primary contributor to our climate temperature at the moment, but to think that a government is entirely responsible for climate temperature is like saying your parents are responsible for the current behaviour of the sun. It is too simplistic, and it will encourage people to believe that a government has more say about reality than it does. We should prepare for warmer and colder climates: In our near future, there could be a small scale nuclear war between Pakistan and India, there could be a massive volcanic eruption or a meteor strike. This last era of climatic temperature stability was a lucky thing that let civilization rise as quickly as it did. A responsible government would harden it's seed stocks against warmer/colder temperatures and train up its youth to be dynamic and imaginative problem solvers.
