Stunning satellite imagery shows Greenland ice melt ‘splash’ over three days

Astonishing satellite imagery shows Greenland’s ice “splash melt” in three days – enough to fill 7.2 MILLION Olympic-sized swimming pools.

  • From 15 to 17 July, a heat wave hit Greenland, causing its ice sheet to melt significantly.
  • A satellite image captured the event, showing the once-frozen water now turning blue as it moves over land and out to sea.
  • The data shows the ice sheet lost 18 billion tons of water in those three days, enough to fill 7.2 million Olympic-size pools.
  • The melting of the Greenland ice sheet has contributed to sea levels rising by about half an inch over the past 30 years.

Greenland experienced a “melt surge” from July 15 to 17 when its massive ice sheet lost enough water to fill 7.2 million Olympic-sized swimming pools. water completely changes the landscape.

European UnionThe Copernicus satellite captured a scene caused by climate change showing areas of turquoise and varying shades of blue representing meltwater flowing over bedrock surfaces, which should be whitish in color because it is normally frozen.

The surprising melt was due to a heat wave sweeping the country, which swept the area at a constant 60 degrees when temperatures typically don’t rise above 50 degrees at this time of year, according to the data. CNN who first reported it.

Although there have been many melts in previous years, the recent melt is twice as large as usual and experts warn it has contributed greatly to global sea level rise.

The melting of the Greenland ice sheet has contributed to sea levels rising by about half an inch over the past 30 years, but if the entire 695,000-square-mile structure were to completely melt, that would raise levels by 20 feet, flooding many of the world’s coastal areas. cities.

The dramatic melting of Greenland, which occurred July 15-17, was captured on satellite imagery. Shades of blue are actually melted ice breaking through the bedrock surface into the sea.

This was stated by Ted Scambos, senior scientist at the Center for Geosciences and Observations at the University of Colorado and the National Snow and Ice Data Center (NSIDC). USA TODAY that most of the melting was caused by the influx of warm air from the Canadian Arctic Archipelago.

The Canadian Arctic archipelago is located just north of the Canadian mainland, which has also been hit by a heatwave that has pushed temperatures above 60 degrees Fahrenheit, usually freezing in July.

However, the warm wind was joined by the high pressure dome over Greenland, resulting in calm winds and sunny skies, causing temperatures to rise.

According to Weather and climate: “In July, the average daily maximum temperature is cold and ranges from 6°C (43°F) at Kaptobin to 10°C (50°F) at Angmagssalik. Nighttime temperatures typically drop to 2°C (36°F) at Angmagssalik and 0°C (32°F) at Cap Tobin. This is one of the warmest months of the year.

This “surge of melting” occurred because the temperature was 10 degrees above normal. Greenland has a stable 60 degrees for three days in a row.

Greenland has a massive ice sheet that is rapidly melting due to rising temperatures.  Experts say that if the entire ice sheet were to melt, sea levels would rise by 20 feet.

As a result of the melting, six billion tons of water poured into the surrounding sea.

As a result of the melting, six billion tons of water poured into the surrounding sea.

As a result, six billion tons of ice were lost in just three days.

The Greenland ice sheet is the second largest mass of freshwater ice on the planet, second only to Antarctica.

The Arctic is warming rapidly due to climate change. The latest data for April shows that the region could be warming four times faster than any other region in the world.

The melting of the Greenland ice sheet began in 1990 and has accelerated since 2000.

On July 27, 2021, Marco Tedesco, a climatologist at Columbia University, reported that the Greenland ice sheet lost 8.5 billion tons of surface mass in one day, enough to cover Florida with two inches of water.

However, this extreme melting occurred at temperatures above 68 degrees.

But it was 2019 that broke all melting records.

Researchers at the Center for Polar and Marine Research found that the ice sheet lost a total mass of 532 gigatons, up 15 percent from the previous record holder in 2012.

And Scambos told USA Today that a melt is coming.

“We can expect about 100 billion tons of water to enter the ocean. Greenland as a whole is losing huge amounts of ice each year,” he said.

SEA LEVEL MAY RISE 4 FEET BY 2300

Scientists have warned that global sea levels could rise by 1.2 meters (4 feet) by 2300 even if we reach the Paris 2015 climate targets.

Long-term changes will be caused by ice melt from Greenland to Antarctica, which should change global coastlines.

Rising sea levels threaten cities from Shanghai to London, low-lying areas of Florida or Bangladesh, and entire countries like the Maldives.

It is imperative that we rein in emissions as soon as possible to avoid even more growth, says a new report from a German-led research team.

Sea levels will rise by 0.7 to 1.2 meters by 23:00, according to the report, even if almost 200 countries fully meet the targets of the 2015 Paris Agreement.

The targets set by the agreements include reducing greenhouse gas emissions to zero in the second half of this century.

Ocean levels will rise inexorably as industrial heat-trapping gases already released will linger in the atmosphere, melting more ice, the report said.

In addition, water naturally expands when heated above four degrees Celsius (39.2 °F).

Every five years of delays in peak global emissions beyond 2020 would mean an additional 20 centimeters (8 inches) of sea level rise by 2300.

“Sea level is often presented as a very slow process that you can’t do much about… but the next 30 years really do matter,” said study lead author Dr. Matthias Mengel from the Potsdam Institute for Climate Impact Research in Potsdam. Germany.

None of the nearly 200 governments that signed the Paris Accords are on track to fulfill their obligations.
