Part I in this series on the Sun and climate described how we know that the Sun has been responsible for some of the major climate changes that have occurred over the past 11,000 years. In Part II, we considered a range of changes that the Sun is causing in the climate today, including changes in the planet’s rotation and in the polar vortex that are changing the frequency of cold winters.
None of the evidence for the Sun’s effect on climate we reviewed is included in the IPCC reports. The role of the IPCC is to assess the risk of human-induced climate change, not to find the causes of climate change, which since its inception has been assumed to be due to our emissions.
Main solar theories
Nevertheless, some scientists continue to try to explain the Sun’s effect on climate and have developed three different explanations. These three theories are not mutually exclusive. The fact that one is true does not mean that the others are false.
The first theory is based on the direct effect on climate of changes in solar radiation. Because the effect is proportional to the cause, we say it is linear.
