A new NASA study provides space-based evidence that Earth's tropical regions were the cause of the largest annual increases in atmospheric carbon dioxide concentration seen in at least 2,000 years.

NASA will hold a media teleconference at 11 a.m. PDT (2 p.m. EDT) Thursday, Oct. 12, to discuss new research to be published this week on changing global levels of carbon dioxide in the atmosphere.

The number of instruments on the International Space Station dedicated to observing Earth to increase our understanding of our home planet continues to grow.

Scientists have produced the first global maps of human emissions of carbon dioxide ever made solely from satellite observations of the greenhouse gas.

The concentration of carbon dioxide in the atmosphere has reached a record-high level, ushering in a "new era of climate reality," according to the United Nations' World Meteorological Organization (WMO).

Kristyn Housman grabbed the end of a sampling auger, a steel tube that two colleagues had just drilled into a moss-covered hummock in a peat bog, and poked through a damp, fibrous plug of partly decomposed peat.

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.

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.

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.

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.

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.

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...

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.
>
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.

Every part of the mosaic of Earth's surface -- ocean and land, Arctic and tropics, forest and grassland -- absorbs and releases carbon in a different way.
