I wonder if a professional could explain to me the logic that says rising temperatures as per a greenhouse effect (ie from an overpressure of CO2) will produce droughts ?

From my science, droughts would be the least likely outcome, because as the seas get warmer then water evaporation increases, which leads to more clouds, rather than less clouds, which cools and brings rain.  Show me how a 1C temperature rise can "bake the ground dry".

This is show down time..... because I will be out of here shortly.

It seems the carbon dioxide proponents are changing their story day by day to fit the unfolding observations. This is not science, if anything this is total BS.  The science should predict the unfolding events, ACCURATELY, you can not afford a hit and miss approach.  If anything, the CO2 model has been shown to be false by the unfolding situation and can no longer be tenetable.

If this is the case you guys are in real trouble.

Y'all are in real trouble anyway, IMO, and no one has realised yet just what are the real and expected consequences of an oil film on the seas.

If you don't accurately identify what is causing the climate shift, you won't be able to find a remedy,
BUT more importantly you can not determine when the tipping point will occur, at which point from then on nothing can be done. Oh, you might have a foul tasting drink of something like cool clean fresh water, but where will the water come from to quench the parched land?

IMO the tipping point passed several years ago, despite my loud and ?clear protestations, the climate just ignored me and so did the policy makers, LOL.  Your call now.

Zarkov,

I'll use small words so that maybe you can follow along. The impacts of global climate change vary considerably by region. It is fairly straightforward to predict global temperature changes, but much harder to predict regional and local ones. (That's because global atmospheric systems are kinda sorta complicated.) And it is harder yet to figure out how local temperature changes impact conditions.

But luckily for us, there are some really big brains working on the problem including, in support of this report, the Climate Impacts Group at the University of Washington, which is one of the leading research organizations in the nation.

So to return to your semi-question, how can climate change induce drought? It's pretty obvious if you think about it. Lots of places--like the Pacific Northwest and a huge swath of Asia--depend on snowpack for water. When the temperature goes up, the snow melts and also precip falls as rain instead of snow. So it's very possible for climate change to bring both more flooding (especially in the winter and spring) and more drought (especially in the summer and fall).

I hope you don't let flamers take down a really valuable blog.

Just when you think you've got your wackadoo cosmologies in order, along comes Galacto to throw a metaphysical wrench in the works!

(Don't worry, Steven T, I won't let it get out of hand. Now tell me, have you accepted Galacto as your lord and savior?)

>> depend on snowpack for water.

OK, so what is snow ?
frozen rain (in a sense)

Therefore if no snow melt then rain falls from the sky instead.

As reported to me 20 years ago, the snow failed in Switzerland, but it still rained.

And what explanations do you have for places where it used to rain, but no more.  Sorry you excuses do not cut with me, I am a hard headed scientist.

Forget the small meaningless words, please reply to the question in scientific terms, I can take it.
Ta.

Zarkov, let me explain how it is happening here in Finland. You are right that we do get more rain. The problem is, that we get less rain during the growing season and more during the winter. AND the winter rain comes increasingly as water rain, not snow as it used to. That means it will flow away quickly in rivers, rather than being slowly released by melting in the spring. Net result: dry springs and summers.

That is exactly what is happening in England as well. I complained all summer about the drought, now I won't shut up about the endless rain.

Another anomaly: If the Gulf Stream quits, it may very well be a deep freeze here in Northern Europe, while the rest of the world bakes.

I am always interested in other people's backyards.

All the Northern Hemisphere, is in transition from their normal climate to deserts, no snow is the first sign, then no winter rains, then....

We have gone through all that down under, and now people are realising that all is not well...even in Finland.
