Provenancing Dust in Ice Core records using Isotopes
Ice core records are an important foundational archive for paleoclimatology. Through them scientists have reconstructed high resolution atmospheric CO2 and temperature records covering hundreds of thousands of years. This captured ancient air allows unique direct access to paleo-atmospheric oxygen and carbon isotopic composition to a range of applications. Importantly, beyond these variables, ice ...

Using satellites to track groundwater depletion in California
Researchers have pioneered the use of a tool that can track the loss of groundwater in California's Central Valley by measuring how much the Earth is sinking. Home to one of the largest groundwater basins in the western United States, the Central Valley supplies about one-fifth of the nation's groundwater demand, a large part of which is used to provide crop irrigation and aid agricultural ...

Global Warming Has Shifted Earth`s Axis
Glacial melting due to climate change is likely the cause of a shift in the movement of the poles that occurred in the 1990s, new research from China shows. Melting glaciers redistributed enough water to cause “the direction of polar wander” to turn and accelerate eastward during the mid-1990s, according to a new study in the peer-reviewed scientific journal “Geophysical ...
