Carbon Dioxide

The human body has a number of mechanisms that prevent you from holding your breath until you suffocate.

Tulip trees were long renowned for their carbon storage. Their unique wood may be responsible.

Volcanoes spewing carbon dioxide 250 million years ago heated the climate so much that extreme El Niño events became the norm, pushing most life on Earth past its limits.

Antarctica is covered by a miles-thick ice sheet, but was that always the case? And when was the coldest continent ice-free?

The carbonate compensation depth — a zone where high pressure and low temperature creates conditions so acidic it dissolves shell and skeleton — could make up half of the global ocean by the end of the century.

Lake Kivu, one of the African Great Lakes, sits along a tectonic plate boundary called the East African Rift, which is dotted with hot springs that feed carbon dioxide and methane into the water.

New research shows that the speed of sound on Mars varies considerably by location and temperature. The findings could help scientists understand sounds picked up by Martian rovers, as well as make future crewed ventures safer.

While the push to reduce carbon dioxide emissions is spurring alternatives to petroleum in other sectors, phasing out plastic, particularly for medical applications, will be very tough.

Every spring, creepy black 'spiders' sprout up on Mars as buried carbon dioxide ice releases dusty geysers of gas. New ESA images show the phenomenon has begun in the strange Inca City formation.

On April 10, a bright red atmospheric "hole" was spotted in the night sky above Texas shortly after SpaceX launched 23 Starlink satellites into space. It is the latest example of an increasingly common phenomenon caused by the company's dying rockets.
