Our Atmosphere

The Earth’s atmosphere is the layer of gases that surrounds our planet. The atmosphere plays a big role in shaping our climate and our weather, and also affects air pollution.

Because of this, many of the biggest environmental challenges we face are connected to our atmosphere, such as climate change, extreme weather, and air pollution.

We are working to understand our atmosphere, how it is changing, and how it impacts life on earth.
