Er, yes it can, lower atmospheric temp and moisture take up will be reduced, then less precipitation.
Likewise, increase atmospheric temp and preciptation will increase.

Nope. Look at this way, if the temps dropped low enough the seas would freeze and damned little evaporation would take place at all.
What actually happens, and can be seen today, is that as temps rise water uptake increases and the rain belts have to move towards the poles, with their lower temps, before condensation can take place and rain, or snow, then falls.
With the loss of cooling from reduced condensation in certain areas, surface temps then also rise, and this as much as the water loss, causes desertification.

The Year the Global Warming Hoax Died

When did the global warming hoax die? Historians are likely to pinpoint 2007. It will take another decade to insure it cannot be revived, but the avalanche of scientific studies and the cumulative impact of scientists who have publicly joined those who debunked the lies on which it has been based will be noted as the tipping point.
Well their explanations are getting more and more desperate Beag. Yesterday one of our national newspapers published lurid 'before and after' pics of the Aral sea and Lake Chad and blamed their shrinkage on 'man made global warming'. Not a single mention that lake Chad has been shrinking since the year dot or that the Aral sea is shrinking due to being used as a water source for massive irrigation.

The title of the article is misleading. He is saying that global warming is not caused by humans. He also says that we are only returning to a level of warmth before the Little Ice Age that ended around 150 yrs. ago. I don't know if he's right about that one.
The problem with the Little Ice Age Beag is, although it is well documented in the UK and parts of Europe, there isn't a great deal of info as to its extent.

As far as I can recall Beag all the pics I've seen of eruptions the ash cloud is heading one way, with the jet Stream that would seem logical as it can hardly reverse its direction.

You're missing my point I think Beag. The post said, (I think), that the ash spread from the Arabian sea, ie east of Indonesia, to the China sea, west!
I can't see how.

Digit I think this belongs in the Volcano thread. But, to answer your question, we can't be sure what direction the jet stream was going 75,000 yrs. ago. It flips from time to time (mysteriously). The jet stream is mainly in the stratosphere, but lower wind currents may go a different direction.
