NASA Flights to Track Greenhouse Gases Across Eastern US
This month, NASA begins an airborne experiment to improve scientists’ understanding of the sources of two powerful greenhouse gases and how they cycle into and out of the atmosphere.

Carbon dioxide levels in atmosphere forecast to shatter milestone
Atmospheric concentrations of CO2 will shatter the symbolic barrier of 400 parts per million (ppm) this year and will not fall below it our in our lifetimes, according to a new Met Office study.

United States absorbed carbon dioxide despite a drought
The warm spring of 2012 in the U.S. caused plants to absorb more carbon, thereby compensating for reductions during the subsequent summer drought, researchers have demonstrated.

Trees Deal With Climate Change Better Than Expected
The bend-don’t-break adaptability of trees extends to handling climate change, according to a new study that says forests may be able to deal with hotter temperatures and contribute less carbon dioxide to the atmosphere than scientists previously thought.

Consumers care about carbon footprint
How much do consumers care about the carbon footprint of the products they buy? Would they care more if the goods were labeled with emissions data?

How Northern European waters soak up carbon dioxide
The seas around the UK and the rest of northern Europe take up a staggering 24 million tonnes of carbon each year.

New climate model better predicts changes to ocean-carbon sink
Since pre-industrial times, the world's oceans have absorbed 41 percent of the carbon dioxide humans have released into the atmosphere. The remainder stays airborne, warming the planet.

Antarctic ice sheet is more vulnerable to carbon dioxide than expected
Results from a new climate reconstruction of how Antarctica's ice sheets responded during the last period when atmospheric carbon dioxide reached levels like those expected to occur in about 30 years, plus sediment core findings reported in a companion paper, suggest that the ice sheets are more vulnerable to rising atmospheric carbon dioxide than previously thought.

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.

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.
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.
