As climate change melts Greenland’s glaciers and deposits more river sediment on its shores, international researchers have identified an unforeseen economic opportunity: exporting excess sand and gravel abroad.
Scientists have developed a possible answer to a longstanding mystery about the chemistry of streamflow, which may have broad implications for watersheds and water quality around the world.
Glacial retreat in the Canadian Arctic has uncovered landscapes that haven’t been ice-free in more than 40,000 years, and the region may be experiencing its warmest century in 115,000 years.
Greenland is melting faster than scientists previously thought—and will likely lead to faster sea level rise—thanks to the continued, accelerating warming of the Earth’s atmosphere.
Ozone layer depletion has increased snowfall over Antarctica in recent decades, partially mitigating the ongoing loss of the continent’s ice sheet mass.
