Greenland Is Melting

If all the ice covering the world’s largest island were to thaw, sea levels would rise roughly 6 meters

  • Greenland is slowly melting
  • This melting adds roughly 1 millimetre of water per year to global sea levels
  • This can mean huge floods in coming years

Like a bowling ball on a skating rink, the black geodesic sphere of the East Greenland Ice-Core Project’s communal living space stands out against the endless white nothingness of the Greenland ice sheet.

 

Iceberg melting can cause huge floods in coming years.

But the real action at East GRIP is under the surface. Researchers are drilling through more than 2.5 kilometres of ice, down to the bedrock below. The ice is sliding fast — for a glacier — toward the sea. Scientists here want to know why. The answer may hold clues to the future of the world’s coastal cities.

Greenland is melting. As it melts, it adds roughly 1 millimetre of water per year to global sea levels. And the pace of melting is quickening.

If all the ice covering the world’s largest island were to thaw, sea levels would rise roughly 6 meters. Scientists don’t know how fast, or how likely, that is to happen. East GRIP is looking for evidence to inform both those questions.

The answers are a matter of growing urgency. The seas are rising faster. And the same processes at work on Greenland’s glaciers at the top of the world could send vast sections of Antarctica’s ice sheet into the sea as well, raising ocean levels even further.

The Arctic is warming twice as fast as the rest of the planet. Scientists studying the rapid changes gather in the small Greenland town of Kangerlussuaq, a former U.S. military base built during World War II. Through the Cold War, this outpost supplied remote radar sites watching a nuclear attack coming over the pole.

These days, military transport planes fly scientists and their equipment across 1,000 kilometres of Arctic ice to East GRIP. They make research possible here and at other far-flung scientific outposts on the vast Greenland ice sheet.

Departing from Kangerlussuaq, VOA visited East GRIP and other remote corners of Greenland with the 109th Airlift Wing of the U.S. Air National Guard for a firsthand look at science in action at the leading edge of climate change. VOA

Spain’s new government declared a national climate emergency on Tuesday, taking a formal first step toward enacting ambitious measures to fight climate change.

The declaration approved by the Cabinet says the left-of-center Socialist government will send to parliament within 100 days its proposed climate legislation. The targets coincide with those of the European Union, including a reduction of net carbon emissions to zero by 2050.

Spain’s coalition government wants up to 95% of the Mediterranean country’s electricity to come from renewable sources by 2040. The plan also foresees eliminating pollution by buses and trucks and making farming carbon neutral.

Details of the plan are to be made public when the proposed legislation is sent to parliament for approval.

More than two dozen countries and scores of local and regional authorities have declared a climate emergency in recent years.

Scientists say the decade that just ended was by far the hottest ever measured on Earth, capped off by the second-warmest year on record.
