American lobsters feeling the heat in the northwest Atlantic
Rising temperatures along the bottom of the Atlantic Ocean will force American lobsters farther offshore and into more northern waters, a new study finds. Climate models project that ocean bottom temperatures in the Atlantic along the U.S. East Coast may rise by up to 4.3 degrees Celsius (7.7 degrees Fahrenehit) by the end of the century. The new study’s results show these rising temperatures will likely make conditions in the American lobster’s southernmost range—less hospitable in the future for juveniles, pushing them farther north and into habitats farther offshore.

Glacial moulin formation triggered by rapid lake drainage
Scientists are uncovering the mystery of how, where and when important glacial features called moulins form on the Greenland Ice Sheet. Moulins, vertical conduits that penetrate through the half-mile-deep ice, efficiently funnel the majority of summer meltwater from the ice surface to the base of the ice sheet.

Collaboration between scientists and stakeholders vital to climate readiness in Alaska
Alaskan residents rely on sustenance species like salmon, caribou, and moose, but their needs can be at odds with companies mining natural resources and conservationists. The state’s future will depend on collaboration between these various stakeholders, and scientists can help bridge the gap between these groups, according to researchers at Southern Oregon University.

Organic aerosols in remote areas have shorter lives than scientists assumed
Scientists find the lifetime of organic aerosols in the upper atmosphere is on the order of 10 days, far shorter than scientists previously assumed.

High-resolution climate models present alarming new projections for U.S.
Researchers have developed new, high-resolution climate models that may help policymakers mitigate the effects of climate change at a local level.
Coastal erosion threatens archaeological sites along Greenland’s fjords
Hundreds of archaeology sites lie along the shores of Greenland’s fjords and coasts, revealing the entirety of the country’s ancestral cultures from as many as four thousand years ago. Coastal erosion, however, may soon drop many of those ancestral links into the ocean.

Cartogram maps provide new view of climate change risk
Scientists have developed cartograms — maps that convey information by contorting areas — to visualize the risks of climate change in a novel way.

Groundwater recharge in the American west under climate change
Groundwater recharge in the Western U.S. will change as the climate warms–the dry southern regions will have less and the northern regions will have more, according to new research.

New Antarctic heat map reveals sub-ice hotspots
An international team of scientists, led by British Antarctic Survey (BAS), has produced a new map showing how much heat from the Earth’s interior is reaching the base of the Antarctic Ice Sheet.

Rising sea levels could weaken coral reefs’ protective influence on Brazil’s coast
Rising sea levels could diminish the ability of Brazil’s coral reef systems to weaken incoming ocean waves, resulting in stronger waves hitting populated areas on the Brazilian coastline, according to new research.
