2016 climate trends continue to break records

Two key climate change indicators—global surface temperatures and Arctic sea ice extent—have broken numerous records through the first half of 2016, according to NASA analyses of ground-based observations and satellite ...

Melt ponds cause the Artic sea ice to melt more rapidly

The Arctic sea ice has not only declined over the past decade but has also become distinctly thinner and younger. Researchers are now observing mainly thin, first-year ice floes which are extensively covered with melt ponds ...

Team finds how the world's saltiest pond gets its salt

Antarctica's Don Juan Pond might be the unlikeliest body of water on Earth. Situated in the frigid McMurdo Dry Valleys, only the pond's high salt content—by far the highest of any body of water on the planet—keeps it ...

Solving the mystery of the Arctic's green ice

In 2011, researchers observed something that should be impossible—a massive bloom of phytoplankton growing under Arctic sea ice in conditions that should have been far too dark for anything requiring photosynthesis to survive. ...

New method forecasts Arctic sea ice melt

(Phys.org) —Arctic sea ice coverage will continue to recover this year from the all-time low of summer 2012, according to experts at the University of Reading.

100-year-old physics model replicates modern Arctic ice melt

The Arctic is melting faster than we thought it would. In fact, Arctic ice extent is at a record low. When that happens—when a natural system behaves differently than scientists expect—it's time to take another look at ...

Melting sea ice may lead to more life in the sea

When spring arrives in the Arctic, both snow and sea ice melt, forming melt ponds on the surface of the sea ice. Every year, as global warming increases, there are more and larger melt ponds.

A 'melted' moon makes for bad future landing sites

The miniature radio frequency (min-RF) radar instrument aboard the Lunar Reconnaissance Orbiter (LRO) is revealing some interesting things about how impact melts form around craters on the Moon. Impacts produce a crater, ...
