Mars, one of our closest planetary neighbors, has fascinated people for hundreds of years, partly because it is so similar to ...

NASA's Curiosity rover has uncovered evidence of a past carbon cycle on Mars. This breakthrough provides scientists with new ...

Atmospheric CO₂ concentrations are surging, even as emissions level out. Natural carbon sinks are showing signs of faltering ...

Tutolo led a new study of rock samples collected by the Curiosity rover that might have answered this question. The mystery ...

Glaciers provide a unique opportunity for researchers to measure levels of atmospheric carbon deposition. Unlike other ...

Plants play a huge role in shaping Earth’s climate. Through photosynthesis, they pull carbon dioxide (CO₂) out of the air.

Billions of years ago, Mars was warm, wet, and capable of sustaining liquid water on its surface. Scientists have long believed the Red Planet once had a dense atmosphere rich in carbon dioxide (CO₂), ...

The Curiosity rover identified hidden caches of the mineral siderite, which could help explain why Mars lost its habitable climate.

The latest anomaly in the climate system that can’t be fully explained by researchers is a record annual jump in the global mean concentration of carbon dioxide in the atmosphere measured in 2024.

The National Oceanic and Atmospheric Administration’s Global ... on the terrestrial carbon sink,” said John Miller, a carbon cycle scientist at the Global Monitoring Laboratory.

including how much comes from atmospheric deposition, can help scientists understand how human activity affects the glacier carbon cycle and ecosystems. Amy Holt and colleagues investigated ...
