Study: China’s Clean Air Policies are Triggering Additional Global Warming

According to a study whose authors include Ken Caldeira, China’s efforts to eliminate its infamous air pollution could cause an additional 0.1C NH warming, because less sunlight will be reflected by aerosols. However, despite suggesting China’s improved air quality is a “climate setback”, Caldeira acknowledged cleaner air is a net improvement.

COVID-19 lockdowns significantly impacting global air quality

American Geophysical Union WASHINGTON–Levels of two major air pollutants have been drastically reduced since lockdowns began in response to the COVID-19 pandemic, but a secondary pollutant – ground-level ozone – has increased in China, according to new research. Two new studies in AGU’s journal Geophysical Research Letters find nitrogen dioxide pollution over northern China, Western…

How NASA is Helping the World Breathe More Easily

From NASA April 14, 2020 How NASA is Helping the World Breathe More Easily Look around. Can you see the air? No? Luckily, many of NASA’s Earth-observing satellites can see what the human eye can’t — including potentially harmful pollutants lingering in the air we breathe. From the vantage point of space, these satellites help…
