Global warming new thread

That's not what your article is claiming. You may have a gut feeling that China have climate change on their minds but the article mentions other reasons.

With the plateau warming more than three times faster than the global average according to Chinese data, glacial recession, especially in the eastern Himalayas, and the thawing of Tibet’s permafrost (or permanently frozen ground) have accelerated.

did you miss this bit.

China controlling some areas of water

Starts with A theoretical link that doesn't actually contain any details at all and may as well be disregarded as a result. So add some detail.

It's true that Tibet has a number of lakes but only some are freshwater and of a glacial type, So what is the climate like
The climate of Tibet is severely dry nine months of the year, and average annual snowfall is only 46 cm (18 inches), due to the rain shadow effect. Western passes receive small amounts of fresh snow each year but remain traversible all year round. Low temperatures are prevalent throughout these western regions, where bleak desolation is unrelieved by any vegetation bigger than a low bush, and where the wind sweeps unchecked across vast expanses of arid plain. The Indian monsoon exerts some influence on eastern Tibet. Northern Tibet is subject to high temperatures in the summer and intense cold in the winter.[4]
18" of snow doesn't relate to many inches of water.

Climate change
The Tibetan Plateau contains the world's third-largest store of ice. Qin Dahe, the former head of the China Meteorological Administration, said that the recent fast pace of melting and warmer temperatures will be good for agriculture and tourism in the short term; but issued a strong warning:
"Temperatures are rising four times faster than elsewhere in China, and the Tibetan glaciers are retreating at a higher speed than in any other part of the world." "In the short term, this will cause lakes to expand and bring floods and mudflows." "In the long run, the glaciers are vital lifelines for Asian rivers, including the Indus and the Ganges. Once they vanish, water supplies in those regions will be in peril."[15]

Not much looking around to find out that in real terms Tibet is not a good source of water into the future.

Major Asian Rivers of the Plateau of Tibet: The Basics - Association for Asian Studies

In relatively recent geologic times, less than forty million years ago, the Indian subcontinent crashed into the Eurasian tectonic plate. As the South Asian plate began to subduct under the Eurasian plate, it pushed up the Himalayas, the Plateau of Tibet, and folded the ranges of mountains to...

Twelve major rivers originate on this uplifted plateau. They provide fresh water for somewhat less than half of the current human population
 
LOL Gas is posting example of noticeable effects of climate change - so far and ignoring that temp will continue to increase unless something is done about it.

is he coming out of the (water) closet in support of climate change activists?

He may be sort of inferring forthcoming water wars. Say China blocks certain water flows out of Tibet to retain glacial flows for as long as possible. A place of flat plains making a good water store? Factors like water wars might crop up all over the place. Increased rain is likely to increase the supply but it needs to be stored.

Water has another problem - populations sizes. China has taken direct action on their aspect of that. Others haven't. Western life style has a tendency to reduce birth rates. Good times then tend to produce bubbles in the age profile of the population. S Korea's birth rate is incredibly low. Only good thing is that the bubbles have a limited lifetime as we all die eventually. Gov's well they may take steps to try and boost the birth rate. Bigger market size might figure. More labour but not so much needed if the population is smaller. GDP can shrink.

Those Green Peace people I mentioned. What they were really saying is more thought was needed due to economic factors. Those run the world. Current UK Greens? Our local CO2 production is relatively low. Throw in imports and an entirely different number will crop up. That other than not importing is totally out of our control. So what is the main reason for heading in that direction the way we are. Pretty simple really energy security. Hardly gets a mention.

Where the water wars of the future will be fought

A new report warns about the increasing likelihood of international conflicts over water.

The posterboy issue is the Ethiopian dam which could dry Egypt.

Given that to the Daily Mail reader,
the Aral Sea is awfully foreign and someone else's problem which obviously we wouldn't have allowed in the west,
the Indus valley etc is surely too far away to matter, so it's their problem
the vast swathe across Africa is , well, full of Africans so they're used to suffering and moving around,
the one that matters, may be the monster in the USA, where the farmers are draining the ancient aquifers to irrigate crops at a stupefyingly stupid rate so will be moaning quite soon when they're hungry.
The yanks might wish they'd done more to keep Putin out of Ukraine's fields, though they're drying up too iirc.
 
If you're enjoying a rainy day as i am then this report in the Grainada will cheer y'all up no end...The seemingly “never-ending” rain last autumn and winter in the UK and Ireland was made 10 times more likely and 20% wetter by human-caused global heating, a study has found. Perhaps Mr Khan should consider turning London into a 'Sponge City' after all...and sponge more dosh from the locals to pay for all this. :mrgreen:
