Solar variability helps explain cold winters

Post by kramer » Mon Oct 10, 2011 5:22 am

Research from the Met Office has shed new light on a link between decadal solar variability and winter climate in the UK, northern Europe and parts of America.

The study, carried out with Imperial College London and the University of Oxford, shows that low UV output from the sun can contribute to cold winters over parts of the northern hemisphere, such as recently seen in the UK. Years of higher UV have the opposite effect.

Adam Scaife, one of the scientists involved in the research, said that while some studies have observed a link between solar variability and winter climate, our research establishes this as more than just coincidence.

He said: "We've been able to reproduce a consistent climate pattern, confirm how it works, and quantify it using a computer model based on the laws of physics. This isn't the sole driver of winter climate over our region, but it is a significant factor and understanding it is important for seasonal to decadal forecasting."

New data from sensitive satellite equipment shows UV variability over the 11-year solar cycle may be much larger than previously thought and has been key to the research. ... ariability

So, the highest levels of CO2 in millions of years isn't going to keep us from freezing our democrats off?
“We should have been warned by the CFC/ozone affair because the corruption of science in that was so bad that something like 80% of the measurements being made during that time were either faked, or incompetently done.”
