Until now, scientists have struggled to know where the organic molecules from these emissions go, and what happens to them once they leave their source. Climate and air quality models therefore have been incomplete or less than accurate.

A week before world leaders sat down for a major climate conference in Copenhagen this month, an international scientific body released the first comprehensive report on the current state of Antarctica’s climate and its relationship to the rest of the globe.

Bob Henson | 9 December 2009  •  When assessing the health of the U.S. stock market, most observers focus on collective measures such as the Dow Jones or S&P 500 indexes, rather than the performance of a single stock. ...

The Climate Scoreboard uses the C-ROADS simulation to calculate the long-term climate impacts of proposals under consideration in the negotiations to produce a global climate treaty. Embedded Scoreboards automatically update as the deal improves. ...

Using R, scientists can build complicated graphical images from statistical analyses. An example is this graph, which shows an ensemble reconstruction of Northern Hemisphere annual temperatures and the maximum decadal average based on annual climate proxies and an energy balance model. ...

As a graduate student in physics, Maura Hagan found herself frustrated and on the verge of dropping out. "I wanted to quit but the chair of the physics department would not allow me to," she recalls. ...

Ph.D. student Dee Rossiter studies low-lying stratocumulus clouds over the subtropical ocean—the area just north and south of the tropics. These clouds form near continents where cold upwelling water reaches the ocean surface; on average, they cover about a third of the world’s oceans. ...

Weather is the state of the atmosphere at a given time and place. Most weather takes place in the troposphere, the lowest layer of the atmosphere.

The world's oceans are absorbing less carbon dioxide (CO2), a Yale geophysicist has found after pooling data taken over the past 50 years. With the oceans currently absorbing over 40 percent of the CO2 ...
