This Week from AGU: Greenland Ice Sheet melting can cool subtropics and alter climate


Greenland Ice Sheet melting can cool subtropics and alter climate

A new study in Paleoceanography finds evidence that the last time Earth was as warm as it is today, cold freshwater from a melting Greenland Ice Sheet circulated in the Atlantic Ocean as far south as Bermuda, elevating sea levels and altering the ocean's climate and ecosystems.

Analysis of 1883 at-sea rescue leads to new understanding of wave energy

A team of oceanographers has developed a new model for ocean wave energy, using an 1883 account of how a ship's crew dumped oil into stormy seas and calmed the waves enough to save the crew of a sinking ship. The study is described in a new paper published in Geophysical Research Letters.

Greener cities could help urban plants endure summer heat

A new study in Geophysical Research Letters indicates that adding more greenery to the urban landscape could help urban vegetation cope better with the summer heat and a warming climate.

New climate index based on atmospheric pressure produces more accurate predictions of storm wave conditions A method based on the north-south atmospheric pressure gradient along the Atlantic coast of Europe could lead to enhanced forecasting of extreme wave conditions and increased preparedness within coastal communities, a new study in Geophysical Research Letters suggests.
