50 YEARS of cold winters

Yeah, its been suggested by Svensmark that solar sunspot activity affects the ability of cosmic rays to form clouds and there is some basic science and some empirical evidence to support him. As you might know cloud chambers are used to show the existence of radiation, alpha, gamma and beta produce different trails in a magnetic field in a cloud chamber. The solar wind created by sun spots blows away cosmic rays, leading to less clouds, and thus warming. When the sun goes quiet, more clouds are formed leading to cooling. Its not a new theory, Herschel, the Royal Astronomer, noted a correlation between sun spot activity and the price of grain. --edit-- And no doubt this thread will be flamed, shame, its an interesting topic. :)

Yeah, it is quite telling.

I thought that global temperature was linked to the number of pirates. :-D Changes in sunspot activity that apparently cause temperature changes on Earth don't cause corresponding temperature changes on Mars, so I am suspicious of claims of a direct link.

Mars is a) much further away and b) has a very much thinner atmosphere and c) has no ocean to stabilise the temperature.

If (c) was a factor then sunspots should have more of an effect.

So there are no pirates on Mars?

No, for it is dynamic stability. Otherwise we would be boiling all day and freezing at night. The sunspots are indicators of a long term solar output, not the cause of the fluctuations.

Must admit - that had escaped me. ...Although I am thinking of another one for the end of the month where I draw reference to a weatherman whose 'scientific forcasting' had prediced temperatures of up to 33 C for these parts this month. Most days we are lucky to get 13 C... I wonder how he gets if funding

I don't discuss it because I know enough to know that I don't know enough about the science behind the global warming debate to be able to have a reasoned discussion on it; so I leave the topic well alone.

But the average day and night-time temperatures would have changed with sunspot activity if there was a link, and they didn't.

Mars does not have a water vapour atmosphere that can form clouds thus the interplay between cosmic rays and solar wind is not the same. However, in respect of the variability of the suns production of heat, then this does affect mars: http://news.nationalgeographic.com/news/2007/02/070228-mars-warming.html[^]
