Earth warming more quickly than thought, new climate models show

Greenhouse gases thrust into the atmosphere mainly by burning fossil fuels are warming Earth's surface more quickly than previously understood, according to new climate models set to replace those used in current UN projections, ...

New insight into how much atmosphere Mars lost

A key tracer used to estimate how much atmosphere Mars lost can change depending on the time of day and the surface temperature on the Red Planet, according to new observations by NASA-funded scientists. Previous measurements ...

New discovery holds promise for reducing climate change threats

Researchers at Tuskegee University have modified and discovered new bio-based natural materials that could eliminate the harmful buildup of carbon dioxide in the atmosphere. They believe the use of naturally occurring nanocellulose ...

415.26 parts per million: CO2 levels hit historic high

Scientists in the United States have detected the highest levels of planet-warming carbon dioxide in Earth's atmosphere since records began, sounding new alarm over the relentless rise of man-made greenhouse gas emissions.

North Atlantic warming hole impacts jet stream

The North Atlantic warming hole (NAWH), a region of reduced warming located in the North Atlantic Ocean, significantly affects the North Atlantic jet stream in climate simulations of the future, according to a team of researchers.

Tectonics in the tropics trigger Earth's ice ages, study finds

Over the last 540 million years, the Earth has weathered three major ice ages—periods during which global temperatures plummeted, producing extensive ice sheets and glaciers that have stretched beyond the polar caps.
