For me the biggest question is why is that period of time considered the "baseline". The climate is a dynamic system in constant change. There has never been a static period of climate. It is forever in flux. Climate Change is the normal state of climate. The REAL question is, how much of the observed rate of change is attributable to human factors, and what is the most effective way to combat the emergence of a potentially hazardous climate scenario.

I am personally in the camp of plant more trees. It is a fact that sunlight falling onto a plant causes the energy to be converted into cellular metabolism and sequestering CO2. A desert however will absorb and then re-radiate a lot of that heat. We need to stop deforestation and take advantage of the higher c02 levels to grow more plants. Hell lets start some geo-engineering projects which will be useful for when we need to terraform other planets.
