Friday 20th November 2009 It's not that I don't believe...

... it's just that I can be both cynical and sceptical.
There has been a lot of noise over the last few years concerning changing conditions on planet earth. A few years back it was the hole in the ozone layer. We were all going to look like toads due to skin cancers due to CO somethings in power transformers and air conditioners and spray cans. Oh, woe was me.
The latest scare seems to be the warming of the late great planet earth because we all burned fossil fuels and but all that carbon into the atmosphere and so earth got warmer. Wasn't there something about that with spray can thingy destroying the atmosphere. Was it an ice age coming or a heat wave? I am not sure. Anyway, the latest is about carbon. And there are all sorts of schemes on the go, all guaranteed to fatten some one bank balance.
Well I was doing a bit of reading the other day on a subject not even remotely related to climate change and all that stuff. Have a read of this.
I quote a bit:
"The longest minimum on record, the Maunder Minimum of 1645-1715, lasted an incredible 70 years. Sunspots were rarely observed and the solar cycle seemed to have broken down completely. The period of quiet coincided with the Little Ice Age, a series of extraordinarily bitter winters in Earth's northern hemisphere. Many researchers are convinced that low solar activity, acting in concert with increased volcanism and possible changes in ocean current patterns, played a role in that 17th century cooling."

Oh really? 70 years do we say? And some bitter cold winters? You don't say. Well, fancy that now. Oh, my.
Now maybe it is the sun? So, let me get this clear. The sun has a long period without sun spots and sun flares. Reduced radiation heading for planet earth and a period of extreme cooling on planet earth? Very very interesting.. I say no more.
