How much of a role does the Sun play in climate change?

The UN’s Intergovernmental Panel on Climate Change (IPCC)’s most recent 6th Assessment Report (AR6, 2021) concluded that the global warming since the 19th century is mostly human-caused. The reports explicitly ruled out the possibility that solar activity was a major factor.

However, a few weeks before the IPCC report was published, an independent and comprehensive scientific review was published in the peer-reviewed journal, Research in Astronomy and Astrophysics. This review suggests that solar activity could potentially explain most of the global warming since the 19th century. Dr. Willie Soon, a co-author of this review, talks here about possible reasons for the different scientific opinions.

Clip taken from Dr. Soon’s April 11, 2022 talk at Hillsdale College in D.C., “The Weaponization of Science: Politics, Vilification, and the Climate Debate”.
