Most climate models set the concentration of methane for long-term simulations. Example concentrations are shown for two seasons: (a) December, January, and February and (b) June, July, and August. This study instead drives the simulations with regionally varying emissions, which leads to sharper gradients in atmospheric concentrations of methane for (c) December, January, and February, and (d)…

The debate on the extraterrestrial origins of the exocomet rages on

Water is also a worry, with producers recycling a far lower percentage than in 2023, led by Western Slope and Front Range operations

After the 2022 Hunga Tonga-Hunga Ha’apai eruption, satellites spotted a strange formaldehyde-rich plume drifting across the stratosphere. Researchers say the cloud revealed a rare burst of methane destruction powered by seawater, ash, salt, and sunlight.

Wastewater treatment plants, like this one in Minnesota, are sources of urban methane emissions, which are on the rise around the world. Credit: Chad Davis/Flickr, CC BY 2.0

A plasma reactor transforms stubborn methane into methanol, bypassing extreme heat and pressure entirely.

The unusually empty streets of Hell’s Kitchen, New York, were the result of COVID-19-related lockdown protocols enacted in 2020. Lockdowns may have also inadvertently contributed to a spike in atmospheric methane levels. Credit: Brecht Bug/Flickr, CC BY-NC-ND 2.0

Repealing the EPA’s endangerment finding on greenhouse gases “isn’t about saving taxpayers’ money, it’s about saving an industry that has already been exposed as a permanent danger to American families,” said the head of 350.org.
