New findings explain how soil traps plant-based carbon
When carbon molecules from plants enter the soil, they hit a definitive fork in the road. Either the carbon gets trapped in the soil for days or even years, where it is effectively sequestered from immediately entering the atmosphere. Or it feeds mic.....»»
Comparing carbon-trapping capacities of anoxic basins
Humans will need to both drastically reduce emissions and remove at least 10 gigatons of carbon dioxide from the atmosphere per year to avoid the worst effects of climate change, according to the Intergovernmental Panel on Climate Change 2023 synthes.....»»
Study predicts best times for Curiosity to sample Mars" methane
Since methane was first detected in Mars' atmosphere 20 years ago, scientists have struggled to uncover its origins and how it is transported around the Red Planet. Measurements from atmospheric samples collected by NASA's Curiosity rover at Gale cra.....»»
Study tracks how wetland tree stem emissions vary by season, location, and hydrological conditions
The recent rise in atmospheric methane (CH4) has drawn increased attention to the potent greenhouse gas, which is approximately 45 times more powerful than carbon dioxide at trapping heat in the atmosphere. About 60% of global methane emissions are a.....»»
We"re heading for Venus: ESA approves EnVision
ESA's next mission to Venus was officially "adopted" today by the Agency's Science Program Committee. EnVision will study Venus from its inner core to its outer atmosphere, giving important new insight into the planet's history, geological activity a.....»»

Hubble recently identified water vapor in the atmosphere of a small, hot exoplanet......»»
Study shows much more pollution leaking into atmosphere from oil sands operations than thought
An international team of chemical and environmental engineers has found that oil sands operations in Canada are emitting significantly more pollutants into the air than previously thought. In their study, reported in the journal Science, the group co.....»»
NASA automated system predicts asteroid impact over Germany
NASA recently predicted the impact of a small asteroid which burned up in the atmosphere over Germany, using its impact prediction system, Scout......»»
Planetary size and associated cooling rate may explain why Mars died while Earth survived
We know of Mars as the red planet, for its surface and atmosphere is caked in endless swirling dust of rusted iron, the rusting action provided by the always-eager oxygen. But this was not always so......»»
Methane pulses on Mars possibly driven by atmospheric pressure changes
New research shows that atmospheric pressure fluctuations that pull gases up from underground could be responsible for releasing subsurface methane into Mars's atmosphere; knowing when and where to look for methane can help the Curiosity rover search.....»»
As another cyclone heads for Queensland, residents must be ready for torrential rain and floods
We've long known cyclones are heat engines, fueled by hot water. They also pump heat from the hot tropics into cooler areas. But they're starting to behave differently. As the world heats up, the atmosphere can hold more moisture. When cyclones form,.....»»
