Earth’s climate is characterized by persistent westerly jets (eastward flow) in the upper troposphere, located in the mid-latitudes of the Northern and Southern Hemisphere, which are associated locally with strong weather systems. The location of these jets is of paramount importance to human...

Subpolar ocean gyres (large systems of rotating ocean currents) in the Southern Hemisphere are found poleward of the Antarctic Circumpolar Current near the Weddell and Ross Sea. They play a key role in the global energy and water budgets. These gyres are crucial for the transport of heat around the...

(CNN) Most of us can appreciate that the world is an ancient place and that a lot has changed in the almost 4.6 billion years since it took its shape. It’s not easy to have a feel for the amount of time that has passed, but grappling with deep time helps you understand why an atmospheric ...

We are currently on the eve of a world with ~400 parts per million (ppm) of atmospheric carbon dioxide (398.35 ppm as of May 2nd, Mauna Loa Observatory). How global climate, sea-level and ecosystems will respond to this level of CO2 level is a key question for global change research. Recently,...

Pearson and colleagues (2013) recently showed how the expansion of shrubs and trees in the Arctic could promote even further warming through a series of positive feedbacks. Their modeling study that estimates the future composition and distribution of vegetation across the Arctic indicated shrubs...

Large-scale carbon sequestration involves capturing carbon dioxide emitted from power plants and injecting it into underground reservoirs for long-term storage. Leakage from these storage reservoirs could lead to groundwater contamination, requiring that the spread of CO2 be monitored during and...

A simple thermodynamic argument suggests that as the water vapor content of the atmosphere increases with global warming dry regions may become drier and wet regions wetter. This enhanced hydrological contrast with global warming can be attributed to changes in the atmospheric water vapor...
