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.
How Mars Got Its Layered North Polar Cap
Orbital wobbling shaped the dome of ice and dust at the planet's north pole, suggests a new study in Geophysical Research Letters.
New Ground-Penetrating Radar Method Shows Promise in Aquifer
Recent advances in ground-penetrating radar data analysis could help reveal aquifer structure in unprecedented detail, according to a new study in Water Resources Research.
Pulses of Rising Magma in Sierra Nevada's Past
A detailed study in Journal of Geophysical Research: Solid Earth of layered igneous material at California's Fisher Lake offers a novel approach to identifying the pathways and timescales of individual magma pulses in volcanic arcs.
