The findings are important because methane is over 25 times more powerful than carbon dioxide as a greenhouse gas. Arctic lakes are already major natural methane sources globally, but the processes ...

A methane feedback loop that is beyond humans' ability to control may have begun, scientists with the National Oceanic and Atmospheric Administration (NOAA) have said. Methane is a powerful greenhouse ...

Roughly two-thirds of all atmospheric methane, a potent greenhouse gas, comes from methanogens. Tracking down which methanogens in which environment produce methane with a specific isotope signature ...

Greenhouse gases have warmed the Earth by 2°F(1.1°C) since pre-industrial times. Of these gases, carbon dioxide is the biggest contributor to climate change. But at least 30% of current warming is due ...

Methane is amongst the most potent of the greenhouse gases, second only to CO2 in contributing to global warming in recent history. Agriculture and livestock activities are a major contributor, with ...

Earth has a cow problem. Cow agriculture is one of the largest emitters of climate-warming methane to the atmosphere. But adding a type of red algae known for its methane-inhibiting properties to cow ...

Rising temperatures could tip the scale in an underground battle that has raged for millennia. In the soils of Earth’s wetlands, microbes are fighting to both produce and consume the powerful ...
