A little test, & a thought for all those global warmists out there, not so brainwashed they canít still think for themselves.

Try wandering outside about 10.00PM on a clear night after one of those 34 C days. Do wear your jacket; these dry nights after westerlies from the desert have heated the day are bitterly cold, especially for late spring.

Now wonder why itís so cold. After all we have all that global warming CO2 up there theoretically re-radiating all that heat back down to us. Pity it doesnít work.

Now wander out there about the same time, same place, after another 34 C day, when the air is moist, there are a few clouds in the sky, & a little dew is falling. Donít bother with your jacket, in fact you wonít need a shirt, the night is warm & welcoming.

All that heat that wasnít being down radiated by CO2 is coming from the water vapor, effectively warming the air around us, re-radiating long wave length radiation that CO2 didnít.

Both Japanese & Russian researchers have results suggesting that increasing CO2 displaces water vapor from the air, thus cooling the planet. Of course our warmists wonít believe that, unless Albanese tells them to. So come on, try to challenge some facts. Tell us why CO2 doesnít warm those cold nights

Hasbeen found it! it was under my bed nice and warm there
We differ you and I always, but somehow I can not change the fact I like you
No true!
Way back when was it 1984? the flying peanut stopped Howard becoming PM, I ran in to three old fellas
Two here in a shop long gone screaming [such folk always scream] that Joe would be PM
The other shop at woodburn on our north coast [I was fishing every weekend near there]holding up a Joe supliment from a newspaper screaming only he could save us
Some times, like this thread I think of you as one like them
But still like a coffee with you one day stay well mate

The nature of day night cycles depends on where you live and what the local and regional weather patterns are doing at any time.

Inland, there is the continental effect: hot during the day, but quite cold overnight; on the coast with the same hot day temperature, it won't get as cold overnight because of the moderating effect of the ocean. Altitude plays a role; the overnight temperature range from the west coast of Tasmania up into the nearby mountains will be more extreme over just a few kilometres compared with the same distance inland on a flat plain. On the other hand, after a few days in the inland over 40 degrees, it stays hot overnight. And, as you note, humidity makes a difference too; humidity will vary depending again of where you live and the local weather pattern at the time.

More C02 in the atmosphere increases the greenhouse effect, retaining more heat (there is plenty of information on the details of this, wavelengths reflected etc etc). That extra heat (=energy) affects the atmospheric circulation. But it doesn't override the temperature gradient from the poles to the equator (though it may moderate it); there is still the effect of large land mass in the northern hemisphere v. large water mass in the southern; and, for Australia, the existing cycles of the Indian Ocean Dipole and ENSO (el nino). We don't know how these will vary in the future. Basically, even with more heat energy in the atmosphere, day-night, summer-winter, pole-equator, land-ocean differences will always be there (though they will vary in intensity) as will the local topography.

But, as to where all the heat has gone - well, some of it into the oceans. One of my brothers has had a long career as a petroleum geologist; he has no doubt about global warming: "Just wait until the oceans release all the heat they've absorbed!"

A couple of points: CO2 and water vapour absorb/reflect different wave-lengths; CO2 doesn't 'displace' water vapour in the air; the atmosphere is not a fixed volume like a bucket, there's room for both!

Hasbeen,

Extraordinary claims require extraordinary proof. That claim is as extraordinary as you can get, yet I've seen no proof at all. Indeed I've never seen any evidence for it (apart from your claiming it here, and I hope you understand why I regard that as such low quality as to be of absolutely no value whatsoever). Though you've claimed researchers have reached those results, you've never posted any links to their papers. And the failure of the rightwing bloggers, the Daily Mail and the Murdoch Press to pick up on it strongly suggests that the error is in your interpretation rather than what any scientists have actually claimed.

The universally accepted view is that the warming from CO2 increases the amount of water vapour in the air, because (as every meteorologist in the world knows) warmer air can hold more of it. And that creates feedback which warms the air even further.
If virtually all of the world's scientists were wrong, and CO2 did somehow displace water vapour, why aren't we experiencing global cooling?
And how exactly could CO2 displace water vapour?

CO2 does slightly reduce the amount of water vapour entering the air by transpiration, and I think the most likely explanation is the results of that are being misinterpreted.

>Of course our warmists wonít believe that, unless Albanese tells them to.
The views of politicians do not determine the facts. Just because you're such an imbecile that you believe what politicians tell you doesn't mean everyone else is!

>So come on, try to challenge some facts. Tell us why CO2 doesnít warm those cold nights
IT DOES!
They'd be even colder without it.

Doesn't anybody but myself get bored with this subject?
Mother Nature will sooner or later reduce the human population to something under the plague proportions it is now.

It's encouraging that she has a balanced view on cause and effect.

Champion of getting things wrong, Paul Eherlich, has found the energy to once again tell us that it's all over because of what happened in 1200BC when, apparently, Egypt, Assyria and Cannan "were burnt to the ground all at once".

If you can be bothered reading this drivel, it is available on news.com.au.
