Carbon dioxide fertilization greening Earth, study findsFrom a quarter to half of Earth's vegetated lands has shown significant greening over the last 35 years largely due to rising levels of atmospheric carbon dioxide, according to a new study.

Melting of massive ice 'lid' resulted in huge release of carbon dioxide at the end of the ice age Date:A new study of how the structure of the ocean has changed since the end of the last ice age suggest that the melting of a vast 'lid' of sea ice caused the release of huge amounts of carbon dioxide into the atmosphere.

Warm nights could flood the atmosphere with carbon under climate changeA new study suggests that hotter nights may wield more influence than previously thought over the planet's atmosphere as global temperatures rise -- and could eventually lead to more carbon flooding the atmosphere.

Excitement Grows as NASA Carbon Sleuth Begins Year TwoScientists busy poring over more than a year of data from NASA's Orbiting Carbon Observatory-2 (OCO-2) mission are seeing patterns emerge as they seek answers to the science questions that drive the mission.

As "good" as it getsThe common adage “good things will come to those who wait” cannot ring truer than for NASA’s Orbiting Carbon Observatory-2 (OCO-2) mission and team members. A little more than a year after launch, the team is proud to make their first milestone in demonstrating the capability and precision of the OCO-2 instrument in measuring atmospheric carbon dioxide (CO2) concentrations.
Watching the planet breathe
When plants photosynthesize, they use energy from sunlight to turn carbon dioxide from the air into sugars used to live and grow. In doing so, they give off a fluorescent light — a glow that can’t be seen with the naked eye, but that can be seen with the right instruments. More photosynthesis translates into more fluorescence, meaning that the plants are very productive in taking up carbon dioxide. The amount of carbon dioxide taken up by plants is called “gross primary productivity,” and is the largest part of the global carbon cycle.
