A new study led by the U.S. Geological Survey and the University of Wyoming found that increased westward ice drift in the Beaufort and Chukchi seas requires polar bears to expend more energy walking eastward on a faster moving “treadmill” of sea ice.  

These findings represent the first assessment of the consequences of changing drift rates for polar bears; one of several previously unexplored effects of sea ice loss.

Globally, from China and Germany to the United States, electric vehicle (EV) subsidies have been championed as an effective strategy to boost production of renewable technology and reduce greenhouse gas emissions (GHG).

But a new study by Concordia economics professor Ian Irvine shows that subsidizing EVs in the North American context will not reduce GHG emissions in the short-term, and may even increase them — at a cost to taxpayers.

The next time you walk down the produce aisle of your grocery store, you may want to reach for red onions if you are looking to fight off cancer.

In the first study to examine how effective Ontario-grown onions are at killing cancer cells, U of G researchers have found that not all onions are created equal.

If projections for melting Antarctic sea ice through 2100 are correct, the vanishing landscape will strip Emperor penguins of their breeding and feeding grounds and put populations at risk.  But like other species that migrate to escape the wrath of climate change, can these iconic animals be spared simply by moving to new locations?

According to new research led by the Woods Hole Oceanographic Institution (WHOI), they cannot. Scientists report that dispersal may help sustain global Emperor penguin populations for a limited time, but, as sea ice conditions continue to deteriorate, the 54 colonies that exist today will face devastating declines by the end of this century. They say the Emperor penguin should be listed as an endangered species. The study was published in the June 6, 2017 edition of the journal Biological Conservation.

Offshore wind turbines built according to current standards may not be able to withstand the powerful gusts of a Category 5 hurricane, creating potential risk for any such turbines built in hurricane-prone areas, new University of Colorado Boulder-led research shows.

The study, which was conducted in collaboration with the National Center for Atmospheric Research in Boulder, Colorado, and the U.S. Department of Energy’s National Renewable Energy Laboratory in Golden, Colorado, highlights the limitations of current turbine design and could provide guidance for manufacturers and engineers looking to build more hurricane-resilient turbines in the future.
