    Carbon dioxide fertilization greening Earth, study finds
    From 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.Carbon dioxide fertilization greening Earth, study finds

    A carbon sink that can't be filled
    Forests can store as much as 45 percent of the world's terrestrial carbon, making them a critical part of the process of regulating climate change.A carbon sink that can't be filled
  • Melting of massive ice 'lid' resulted in huge release of carbon dioxide at the end of the ice age Date: January 4, 2016
    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.Melting of massive ice 'lid' resulted in huge release of carbon dioxide at the end of the ice age Date:
  • Warm nights could flood the atmosphere with carbon under climate change December 7, 2015
    Warm nights could flood the atmosphere with carbon under climate change
    A 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.Warm nights could flood the atmosphere with carbon under climate change

    As "good" as it gets
    The 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.As 'good' as it gets

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.
