One of the things I and others have been saying for years is the biggest influence on our climate (and temperature) hangs in the sky each day and we call “the Sun”. Anthony Watts has a post up today talking about what is going on with the Sun and what that may mean for global temperatures. The process, as I have come to understand it is activity on the Sun (sun spots) generate solar winds (sun’s magnetic field). Solar winds have a tendency to “blow” away cosmic rays and keep them from reaching earth. When cosmic rays reach earth they react with water vapor in our atmosphere and create clouds. Clouds then block sunlight. Heavy cloud cover means cooler temperatures. Light cloud cover means higher temperatures. As I further understand it, none of that is included in climate models.
Well, if Svensmark is right, and Galactic Cosmic Rays modulated by the sun’s magnetic field make a change in cloud cover on Earth, increasing it during low solar magnetic activity, we are in for some colder times.
There’s a presentation by Jasper Kirkby, CLOUD Spokesperson, CERN, which shows what we currently know about the correlations between Galactic Cosmic Rays (GCR’s) and variations in the climate.
The CLOUD experiment uses a cloud chamber to study the theorized link between GCR’s and cloud formation in Earth’s atmosphere. Kirkby talks about the results from the first CLOUD experiment and the new CLOUD experiment and what it will deliver on the intrinsic connection between GCR’s and cloud formation. This is from the Cern, one of Europe’s most highly respected centers for scientific research.
The sun is in a funk – has been for years. Some of the lowest activity every recorded. And what has been happening here? Recorded temperatures have been cooling. Perhaps the funniest (in a sad sort of thing) thing I’ve read are the so-called climate scientists who were lamenting their inability to explain why their models weren’t reflecting this cooling trend and wishing they could explain it.
Look at the charts on Watts’ site, read about the lack of activity on the sun, understand the relationship between activity, solar winds, cosmic rays and clouds and you’ll understand that this is high school science we’re talking about.
Now go read this, especially the commenter’s remarks highlighted in the article, and much of what is going on becomes considerably clearer.
Which leaves me asking – again – how can such “science” that disregards the sun’s effect and raises an 800 year lagging effect (CO2) into a “cause” be taken seriously by intelligent and seemingly rational adults? Forget “consensus” and “conspiracy”. How did the Sun get ignored and CO2 changed from effect to “cause” in this hypothesis which can’t be reproduced?
