I recall, it may have been an horizon programme the facts are indesputable.
Especially when the correlation between reduced sunlight mirrored reduced evaporation when the two graphs were compared purely by chance by the Australians.


One chap first noticed the paradox Dr Gerald Stanhill and his paper was largely igored by the scientific community.

The paradox was that average worlds temperature's were going up but measured sunlight was going down and also despite the increase in world temperatures going up the evaporation rate of water was going down.
You would expect the opposite.

Increased CO2 in the atmosphere is causing global warning, not more sunlight.Global warming has also been studied considerably more since 2005.

Any who has even been in a sauna or steam room will know that heat and water vapour tend to go hand in hand. And, evaporation is faster in a drier environment - when humidity levels rise, evaporation reduces because the air is already laden with moisture, so it's not really a paradox, just basic science (and we've discussed this a lot in the damp/mould discussions!)

More worrying, something scientists have been studying for years - there is a risk that global warming, which is happening, could trigger the next ice age.
A combination of increased cloud cover combined with mass melting of ice could shift the gulf stream and block sunlight, which could cause global temperatures to drop.
And if there's one thing that's worse than global warming, it's an ice age.

Either way, immigration is going to rise significantly over the forthcoming decades as populations are force off their lands thanks to global warming.
 
The programme is thirteen years old so - was/is it true? Haven't heard much about the subject since.
Usual Horizon ?

I didn't watch it all but It said near the end that methane was eight times stronger than carbon dioxide for global warming; isn't it actually twenty three times?

There's some very silly comments posted that show a complete lack of insight and absolute ignorance of the point of the post.........

The documentary is pointing out facts.

The age of the documentary is irrelevant, really anyone saying it's 13 years old so it's irrelevant ....... in fact it's so stupid a comment it's not worth replying

Global dimming a really a problem ?

Quote from the last link ~

The death toll that global dimming may have already caused is thought to be massive.

Climatologists studying this phenomenon believe that the reflection of heat have made waters in the northern hemisphere cooler. As a result, less rain has formed in key areas and crucial rainfall has failed to arrive over the Sahel in Northern Africa.

In the 1970s and 1980s, massive famines were caused by failed rains which climatologists had never quite understood why they had failed.

The answers that global dimming models seemed to provide, the documentary noted, has led to a chilling conclusion: what came out of our exhaust pipes and power stations [from Europe and North America] contributed to the deaths of a million people in Africa, and afflicted 50 million more with hunger and starvation.

Billions are likely to be affected in Asia from similar effects
Scientists said that the impact of global dimming might not be in the millions, but billions. The Asian monsoons bring rainfall to half the world’s population. If this air pollution and global dimming has a detrimental impact on the Asian monsoons some 3 billion people could be affected.

From the site .......
NARRATOR: For 15 years Travis had been researching an apparently obscure topic, whether the vapour trails left by aircraft were having a significant effect on the climate. In the aftermath of 9/11 the entire US fleet was grounded, and Travis finally had a chance to find out.

DR DAVID TRAVIS: It was certainly, you know, one of the tiny positives that may have come out of this, an opportunity to do research that hopefully will never happen again.

NARRATOR: Travis suspected the grounding might make a small but detectable change to the climate. But what he observed was both immediate and dramatic.

DR DAVID TRAVIS: We found that the change in temperature range during those three days was just over one degrees C. And you have to realise that from a layman's perspective that doesn't sound like much, but from a climate perspective that is huge.

NARRATOR: One degree in just three days no one had ever seen such a big climatic change happen so fast. This was a new kind of climate change. Scientists call it Global Dimming. Two years ago most of them had never even heard of it, yet now they believe it may mean all their predictions about the future of our climate could be wrong. The trail that would lead to the discovery of Global Dimming began 40 years ago, in Israel with the work of a young English immigrant called Gerry Stanhill. A trained biologist, Gerry got a job helping to design irrigation schemes. His task was to measure how strongly the sun shone over Israel.

no I wouldn't.

So you think the opposite ............to this.

NARRATOR: For decades, nobody took much notice of the pan evaporation measurements. But in the 1990s scientists spotted something very strange, the rate of evaporation was falling.

PROF GRAHAM FARQUHAR: There is a paradox here about the fact that the pan evaporation rate's going down, an apparent paradox, but the global temperature's going up.

NARRATOR: This was a puzzle. Most scientists reasoned that like a pan on the stove, turning up the global temperature should increase the rate at which water evaporated. But Roderick and Farquhar did some calculations and worked out that temperature was not the most important factor in pan evaporation.

Look it up the subject is global dimming not global warming two different things. Global dimming is indisputable, Global warming is still been debated.

Most people haven't ....911 incident was an eye opener when all domestic flights were stopped in the US.

Your quite right, no one knows about it generally ......I've mentioned it to loads of people .........never met anyone that knows about it including scientists and physics lecturers. Hey ho.......

Most people have heard about Father Christmas. It does not make it true. :rolleyes:

Chemtrail conspiracy theory
Moon Landings
Kennedy Assassination


Any more conspiracy theories that gasbag prescribes to?

I think you will find man did land on the moon and kennedy was assassinated :ROFLMAO:
