Is this climate change or just La Nina?

A record-breaking drought has caused some rivers in China – including parts of the Yangtze – to dry up, affecting hydropower, halting shipping, and forcing major companies to suspend operations.

A nationwide drought alert was issued on Friday as a long-running and severe heatwave in China’s heavily populated south-west was forecast to continue well into September.

The loss of water flow to China’s extensive hydropower system has sparked a “grave situation” in Sichuan, which gets more than 80% of its energy from hydropower.

Great, the river is dry because of a drought. I could not have worked this out for myself Roll Eyes

China's state meteorologists have blamed an increase in the number of extreme weather events in recent years on climate change. But the drought has been intensified by massive deforestation and the pollution and depletion of water resources caused by China’s heady pursuit of economic growth, said Ma Jun, author of "China's Water Crisis". "There is such a tight eco-balance now that whenever we have a problem with a natural climate phenomenon, it causes a big disaster. We don't have much extra capacity to absorb the impact," he said.

So AGW and deforestation in China’s headlong rush to grow the economy is causing the droughts.

Rainmaking is being tried now to get some water into the Yangzte, China’s most important source of drinking water, hydro power generation and transport artery.

That is hotter than Eemian times when sea levels were 20m higher than now.

0.2°C per decade is the rate at which AGW is warming the world now. By 2300 we should be at Eemian temperatures and sea levels will be rising at much faster rates than now.

That is what the science is telling us.

Have a look here: https://www.remss.com/research/climate/

Of course, we could have a nuclear winter or massive volcanic eruptions, much bigger than Krakatoa causing a 2 year winter, etc. But freak accidents aside, 0.2°C per decade is how much global temperatures will rise—and rise for the foreseeable future, so much CO2 absorbed by the oceans that as atmospheric CO2 decreases the oceans, due to the drop in the partial pressure of CO2, will release more CO2 into the atmosphere.

The massively increased population of course puts an ever increasing
strain on China's water supply. And the major evaporative water losses
from millions of hectares of open rice paddies doesn't help.

600 years ago, the Chinese population was ~100 million; today it's ~1.4 billion.

600 years ago, the Chinese population was ~100 million; today it's ~1.4 billion.

The elephant in the room with all the genuine concerns about pollution and depletion of natural resources is population growth. The human race cannot keep increasing without consequences.

It’s so interesting what lay hidden beneath the surface of water.
I’ve often thought what secrets hide down there.

And this one in lake Mead….
