Natural gas was once widely seen as a bridge fuel to renewable energy. But the industry’s methane leaks make it a larger global warming threat than people realized.
It’s the World Health Organization’s first update of global air quality guidelines since 2005. We know far more today about the serious risks these pollutants pose to human health.
Methane is the world’s second most abundant greenhouse gas, and it’s many times more potent than carbon dioxide.

A new study provides a detailed way to calculate the climate impact of food production, which could lead to more sustainable farming policies and methods.
The results of Foote’s simple experiments were confirmed through hundreds of tests by scientists in the US and Europe. It happened more than a century ago.
