By Paul Homewood Repost from Jo Nova: The NASA site used to have a page titled “What are the primary forcings of the Earth system?“. In 2010 this page said that the Sun is the major driver of Earth’s climate, that it controls all the major aspects, and we may be on the cusp […]

We’ve been discussing the sudden rise in UK and European temperatures in the 1990s, and I was reminded about a study undertaken by Clive Best and Euan Mearns looking at the role of cloud cover four years ago:
Clouds have a net average cooling effect on the earth’s climate. Climate models assume that changes in cloud cover are a feedback response to CO2 warming. Is this assumption valid? Following a study with Euan Mearns showing a strong correlation in UK temperatures with clouds, we looked at the global effects of clouds by developing a combined cloud and CO2 forcing model to sudy how variations in both cloud cover [8] and CO2 [14] data affect global temperature anomalies between 1983 and 2008. The model as described below gives a good fit to HADCRUT4 data with a Transient Climate Response (TCR )= 1.6±0.3°C. The 17-year hiatus in…

In this YouTube video Henrik Svensmark and colleagues demonstrate the links between Solar Activity and Climate, arising through interaction of the Solar magnetic field and Solar Wind with galactic Cosmic Rays. A weaker field lets more Cosmic Rays through to our atmosphere. More Cosmic Rays form more ions that nucleate low level clouds. More low level clouds reflect more Solar radiation back into space cooling the planet.
