The Arctic Ocean's blanket of sea ice has changed since 1958 from predominantly older, thicker ice to mostly younger, thinner ice, according to new research published by NASA scientist Ron Kwok of the Jet Propulsion Laboratory, Pasadena, California. With so little thick, old ice left, the rate of decrease in ice thickness has slowed. New ice grows faster but is more vulnerable to weather and wind, so ice thickness is now more variable, rather than dominated by the effect of global warming.

Well-balanced and predominantly plant-based diets can lead to improved nutrient levels, reduce premature deaths from chronic diseases by more than 20%, and lower greenhouse gas emissions, fertilizer application, and cropland and freshwater use, globally and in most regions, a new study reports.

A new large-scale hydroeconomic model, developed by the Water Program at IIASA, will allow researchers to study water systems across whole continents, looking at sustainability of supply and the impacts of water management on the energy and agricultural sectors.

High-tide flooding—sometimes called nuisance flooding—washes into U.S. coastal communities every year, disrupting storm- and wastewater systems, damaging roads and infrastructure, and straining city budgets.

A University of Alberta master’s student is going to the ends of the Earth to learn more about geothermal energy.

Wind shear is an adversary of tropical cyclones like Tropical Storm Nadine, and it is tearing the storm apart in the Eastern Atlantic Ocean. NASA-NOAA’s Suomi NPP satellite captured an image of Nadine as wind shear was affecting it.

Researchers at NYU Abu Dhabi, along with other global scientists, have identified a new mechanism by which warm dust travels from the Sahara Desert to the Arctic Circle, which has been proven to affect rising temperatures and ice melt in Greenland.

A material designed by MIT chemical engineers can react with carbon dioxide from the air, to grow, strengthen, and even repair itself. The polymer, which might someday be used as construction or repair material or for protective coatings, continuously converts the greenhouse gas into a carbon-based material that reinforces itself.

NASA’s Aqua satellite and NASA-NOAA’s Suomi NPP Satellite passed over the Florida Panhandle and captured different views of Hurricane Michael after it made landfall on Oct. 10.  Hurricane Michael is the most powerful storm on record to hit the Florida Panhandle.

Michael introduced itself to North America with 155-mile-per-hour gusts of wind and a barometric pressure of 919 millibars, the third-strongest hurricane to ever make continental US landfall. It was a monster, and it stayed a monster as it rolled through Georgia and then on toward the Carolinas.
