(Phys.org) -- In August 1976 Luna 24 landed on the moon and returned to Earth with samples of rocks, which were found to contain water, but this finding was ignored by scientists in the West.
(Phys.org) -- The fragile and rapidly changing Arctic region is home to large reservoirs of methane, a potent greenhouse gas. As Earth's climate warms, the methane, frozen in reservoirs stored in Arctic tundra soils or marine ...

Why did the atmosphere contain so little carbon dioxide (CO2) during the last Ice Age 20,000 years ago? Why did it rise when the Earth's climate became warmer? Processes in the ocean are responsible for this, says a new study ...
