Dramatic cuts in China’s air pollution drove surge in global warming

The rate at which the planet is warming has sped up since 2010, and now researchers say that China's efforts to clean up air pollution are inadvertently responsible for the majority of this extra warming

In the early 2000s, China had extremely poor air quality as a result of rapid industrialisation, leading to a public outcry in the run-up to the 2008 Beijing Olympics. In response, Chinese authorities fitted scrubbers to coal power plants to curb the dirtiest emissions and tightened rules governing vehicle exhausts, leading to a 75 per cent drop in sulphate emissions.

But there is a sting in the tail of this environmental success story. According to a new analysis, China’s dirty air had inadvertently been cooling the planet, and now that it is gone we are starting to see a greater warming effect.

Not the kinda news story the climate brigade wants to hear. So now what? Everyone back to coal plants?

The consequences of climate change will continue to evolve, the science of climate change remains the same.

Apparently, they gave up, because when I was in Beijing in 2018 it was so polluted you couldn't even see the tops of the buildings.

Remember when they said beef tallow, butter, and whole milk was bad for you?

So here, cook in vegetable oil (mostly soybean oil), spread soybean oil and chemicals on your bread in the form of margarine, and drink what amounts to white water.

How do we measure 0.05ºC? ... go spend the $4 for a Walmart unit and see if you can measure 0.05ºC ...

Look at a box of Cheerios ... see where it says "heart-healthy"? ... now check the salt content ... yeah, Cheerios are the WORST thing you can eat if you have a heart problem ...

Soybeans cause cancer ... haven't you heard yet? ...

The jury is out on that but the perception is exactly why vegetable oil is not called soybean oil on the label.

The warning has been updated: NOT using soybean oil is causing cancer ... damn, we're all gonna die now ...

Imagine breathing that toxic air...all in thr name of some corporate heads making a buck. When that happens average people lose.

Yes! Damn them for making all those things that we need and want. Who do they think they are anyway?!

They can be made here without toxifying the air . The 5 or 15 dollar increase worth it.

LOL Another very stupid person flapping yap and attributing his stupidity to people that understand physics and climate. When we cleaned up our and Europe's aerosol pollution in the 70's and 80's, we saw a rise in the rate of warming. As China and India clean there aerosol pollution up, we will see the same. Obviously it is a good thing when that kind of pollution is eliminated. It harms people and the environment. But then, you MAGAts love things that harm us. And we have an idiot for a leader that wants to increase our present pollution.

Apparently they are having a problem balancing their reduction in air pollution with their desire to keep exporting cheap products. Some information on that;

Yes, air pollution in China has significantly reduced over the past decade, but challenges remain, including recent increases in pollution levels.

Significant Reductions Achieved​

• PM2.5 Concentration Decline: From 2013 to 2022, the average PM2.5 concentration in major Chinese cities dropped from 72 μg/m³ to 29 μg/m³, representing a 50% reduction. This improvement is attributed to stringent government policies aimed at reducing emissions from coal and vehicles.
  
  2
• Global Impact: China's efforts have contributed to a decline in global pollution levels, with the country accounting for a significant portion of the reduction in particulate matter worldwide.

Recent Challenges​

• Rebound in Pollution Levels: Despite the progress, there was a notable increase in PM2.5 levels in 2023, with 80% of China's provincial capitals experiencing higher pollution. This rebound raises concerns about the sustainability of the improvements made.
  
  2
• Ongoing Pollution Issues: Other pollutants, such as ozone (O₃), have not seen similar reductions, and the PM2.5 levels still exceed the World Health Organization's recommended guidelines.

Future Plans​

• Continued Efforts: The Chinese government aims to eliminate severe air pollution by the end of 2025, focusing on improving forecasting systems and coordinated management of airborne particles and ozone.

  In summary, while China has made remarkable strides in reducing air pollution, particularly in PM2.5 levels, the recent uptick in pollution and the need for ongoing management of various pollutants highlight that the battle against air pollution is far from over.

LOL Ah yes, them thar damn Chinks can just die from pollution, why should I care as long as I get cheap products.

I've been to just about every major Chinese city in the past year and in their rural areas as well and unlike China of the early 2000's, their air quality is better than many American cities where they produce nothing but crime and violence.

Whatever they're doing, they're doing it right.
