Clean Air Efforts in China May Have Worsened Global Warming
Imagine China had a lot of dirty air, which acted like a sunshade, cooling the Earth a little.
China cleaned up this dirty air to make the sky clearer.
However, this clean air removed the 'sunshade', allowing more sunlight to reach the Earth.
Since the main reason for global warming (greenhouse gases) was still increasing, the Earth started warming up faster.
Studies suggest that China's clean-up efforts are a significant reason for the accelerated warming.
While it made the air cleaner and healthier, this process has also led to an increase in global warming.
The government is now trying to further reduce emissions to try and fix this.
Scientists are investigating why global warming has accelerated in the last 15 years.
East Asia's efforts to clean up air pollution may have inadvertently accelerated warming.
Air pollution previously cooled the planet by blocking sunlight.
Removing this 'artificial sunshade' caused the Earth to warm faster.
China's clean air actions are responsible for a large percentage of recent warming.
- Who
