An ice core from the Antarctic has given an NSF-funded research team a glimpse into the very distant past. The continuous core sample provides details on how the Earth's climate and atmosphere changed long ago, and gives clues about variations in ice levels. The oldest ice from the bottom of the core may be up to 100,000 years old.

With the need to understand global change one of today’s most pressing scientific challenges, ESA is exploring novel techniques for future space missions. Firing laser pulses between satellites is promising a step up in tracking greenhouse gases.

Scientists in the New York Center for Astrobiology at Rensselaer Polytechnic Institute have used the oldest minerals on Earth to reconstruct the atmospheric conditions present on Earth very soon after its birth.
