How Stable is Deep Ocean Circulation in Warmer Climate?

If circulation of deep waters in the Atlantic stops or slows due to climate change, it could cause cooling in northern North America and Europe – a scenario that has occurred during past cold glacial periods. Now, a Rutgers coauthored study suggests that short-term disruptions of deep ocean circulation occurred during warm interglacial periods in the last 450,000 years, and may happen again.

East Antarctica’s Denman Glacier has retreated almost 3 miles over last 22 years

Irvine, Calif., March 23, 2020 – East Antarctica’s Denman Glacier has retreated 5 kilometers, nearly 3 miles, in the past 22 years, and researchers at the University of California, Irvine and NASA’s Jet Propulsion Laboratory are concerned that the shape of the ground surface beneath the ice sheet could make it even more susceptible to climate-driven collapse.

$8.3M award to WHOI extends observational record of critical climate research

The National Science Foundation (NSF) recently awarded $8.2 million to the Woods Hole Oceanographic Institution (WHOI) to extend the life of the Overturning in the Sub-polar North Atlantic Program (OSNAP) in a key part of Earth’s ocean-climate system. The award is part of a $15.5 million grant to four U.S. institutions that will help add four years to the record being assembled by the observatory.

California’s strict air quality regulations help farmers prosper, UCI-led study finds

Irvine, Calif., March 16, 2020 – Farmers in California’s Central Valley are not known for their love of government regulations, but those same growers have seen a boost in the productivity of their high-value crops – and greater earnings – as a result of the Golden State’s strict air pollution controls. For a study published today in Nature Food, researchers at the University of California, Irvine and other institutions conducted a statistical analysis of pollution exposure and yields from 1980 to 2015 on a key sector making up about 38 percent of the state’s total agricultural output: perennial crops such as almonds, grapes, nectarines, peaches, strawberries and walnuts.

How new data can make ecological forecasts as good as weather forecasts

Soon, University of Wisconsin–Madison ecologist Ben Zuckerberg thinks we’ll be able to pull off the same forecasting feat for bird migrations and wildlife populations as for climate forecasts. That’s because just as those recurring changes in climate have predictable consequences for humans, they also have predictable effects on plants and animals.
