Carbon Dioxide releases are the most likely cause of the current period of global warming. The science is strong enough to justify major reductions in the use of non-renewable energy. However, the science is not strong enough to justify the risk of installing nuclear capacity to reduce carbon dioxide releases.
Here, we summarize the evidence for believing that carbon dioxide is the main cause of the current global warming (the “Carbon Hypothesis”). We then consider the science behind each of the arguments for supporting the Carbon Hypothesis. In each case, we find that the evidence is weaker than appears at first sight. We do not disprove the Carbon Hypothesis, but find that there are other plausible causes of global warming that are consistent with the data.
