Politics cloud the issue of climate change. We have a global economy driven by fossil fuels. Whoever controls the energy controls the power. Some have it and want to keep it. Others lack it but want to grab it. The first political argument often cited is a flat out denial that our climate is warming. However, the scientific evidence is very clear. There are over a thousand years worth of data in tree rings, sediment cores, ice cores, corals, and historical records. The retreat of glaciers and polar ice during the 20th Century has been quantified, and in the case of glaciers, is visible to the naked eye. Along with lab experiments and 160 years of temperature records, the case for warming is undeniable.
