Methane is one of the most powerful greenhouse gases, warming the planet far faster than carbon dioxide over the short term.

As the world races to curb climate change, scientists are taking aim at cows, a surprisingly potent source of greenhouse gases. Science correspondent Miles O’Brien traveled from California to Mexico ...

Methane isn’t just an environmental buzzword—it is energy lost. Every puff of gas from a cow’s rumen represents feed energy that could have gone toward growth, milk or a calf. That simple truth is ...

An electron microscope image of single-celled methanogens, members of the archaea branch of the tree of life. They are ubiquitous in oxygen-free environments, turning simple foods into methane, a ...

Cattle produce more methane than any other livestock. Methane, a greenhouse gas, traps heat, which warms the Earth. It is far more powerful than its more common counterpart, carbon dioxide. When cows ...

Methane spiked in the early 2020s as wetter conditions boosted emissions at the same time the atmosphere’s chemical “cleaner” weakened.
