Carbon Dioxide

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.

At the current emissions level, there is a 50% chance that global warming will exceed 1.5 degrees Celsius consistently in about seven years, new research suggests.

The NISAR satellite, a collaboration between NASA and India's space agency ISRO, will help scientists monitor how climate change is affecting Earth's varied landscapes.

New research suggests we have just six years left to limit global warming to 1.5 degrees Celsius, and two decades to keep temperatures below the 2 C threshold in the Paris Agreement.

The discovery of seemingly home-grown carbon dioxide suggests Europa's ice-covered ocean could be habitable.

NASA's James Webb Space Telescope has detected potential traces of dimethyl sulfide, a chemical only known to be created by phytoplankton on Earth, in the atmosphere of an exoplanet believed to have its own liquid ocean.

The animations highlight emissions from different human and natural sources, with the main contribution coming from the burning of fossil fuels.

The atmospheric temperature spike, which was caused by geomagnetic storms triggered by the sun, suggests the "solar maximum" is fast approaching.
