On our planet, the cycle and balance of carbon from reservoir to reservoir is a matter of life or death. Carbon moves from ...

Ocean color remote sensing (OCRS) provides crucial insights into marine ecosystems, detecting phytoplankton blooms, measuring ...

A new study suggests that Mars may have once had an active carbon cycle, which could explain why the planet was warmer and wetter billions of years ago. Researchers analyzing data from NASA’s ...

Mars, one of our closest planetary neighbors, has fascinated people for hundreds of years, partly because it is so similar to Earth. It is about the same size, contains similar rocks and minerals, and ...

To reach the goals of the Paris Agreement, we not only have to reduce CO2 emissions, but also remove CO₂ from the atmosphere ...

Figure 1: Modelled and observed interannual variability in the atmospheric CO 2 concentration ... extensively tested as part of the Ocean Carbon Cycle Intercomparison Project; it was found ...

The agency maintains the global backbone of measurements of CO2 and other gases, but these are at risk of being curtailed if ...

This release could have slightly delayed Mars' cooling by briefly restoring atmospheric carbon. A functioning carbon cycle is essential for maintaining habitable conditions. On Earth, carbon ...

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

Although it is very thin, the modern Martian atmosphere is still composed mainly of carbon dioxide. In other words, these new results provide evidence for an ancient carbon cycle on Mars.
