Startling satellite images show ‘peak melting’ of ice in Greenland for three days


Startling satellite images show ‘melting peaks’ of ice in Greenland for three days – enough to fill 7.2 MILLION Olympic-size swimming pools

  • Greenland was hit by a heat wave from July 15-17 that caused its ice cap to melt significantly
  • A satellite image captured the event, which shows the once frozen water is now blue as it moves across land and out to sea
  • Data shows the ice sheet lost 18 billion tonnes of water in those three days, enough to fill 7.2 million Olympic swimming pools
  • Melting of the Greenland ice sheet has contributed about half an inch to sea level rise over the past 30 years

Greenland experienced a ‘peak melt’ from July 15-17 which saw its huge ice cap lose enough water to fill 7.2million Olympic swimming pools – and the dramatic event was captured in a satellite image which reveals how 18 billion tons of water runoff completely changes the landscape.

The European Union’s Copernicus satellite captured the climate change-induced scene which shows areas of turquoise and different shades of blue, melting water flowing along the bedrock surface which is expected to be colored whitish because it is usually frozen.

The stunning melt was due to a heatwave that gripped the country and enveloped the region in a constant 60 degrees when temperatures don’t usually top 50 degrees this time of year, according to CNN which first realized the issue.

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

Melting of the Greenland Ice Sheet has contributed about half an inch to sea level rise over the past 30 years, but if the entire 695,000 square mile structure melted completely, it would increase levels of 20 feet, which would flood many coastal areas of the world. cities.

Greenland’s spectacular melting that took place from July 15-17 was captured on a satellite image. The shades of blue are actually melted ice that pushes its way through the bedrock surface and out to sea

Ted Scambos, a senior researcher at the University of Colorado’s Earth Science and Observation Center and the National Snow and Ice Data Center (NSIDC), told USA TODAY that much of the melting was due to warm air coming from of the Canadian Arctic Archipelago.

The Canadian Arctic Archipelago is located north of the Canadian mainland, which was also hit by a heat wave that sent temperatures soaring above 60F – they are usually freezing in July.

However, the warm wind was joined by a high-pressure dome over Greenland, resulting in calm winds and sunny skies, both of which raise temperatures.

Depending on weather and climate: “In July, average high daytime temperatures are cold and range from 6°C (43°F) in KapTobin to 10°C (50°F) in Angmagssalik. Nighttime temperatures generally drop to 2°C (36°F) at Angmagssalik and 0°C (32°F) at KapTobin. It is one of the hottest months of the year.

This “melt spike” was due to temperatures 10 degrees above normal. Greenland has experienced a constant temperature of 60 degrees for three consecutive days

Greenland has a massive ice cap that is rapidly melting due to rising temperatures.  Experts say if the entire ice cap melts it will raise sea levels by 20ft

The melt event saw six billion tonnes of water spill into the surrounding sea

This resulted in the loss of six billion tons of ice in just three days.

The Greenland Ice Sheet is the second largest body of freshwater ice on the planet, second only to Antarctica.

The Arctic has warmed rapidly due to climate change. Recent data from April shows this region could be warming up to 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 Columbia University climatologist, reported that the Greenland Ice Sheet lost 8.5 billion tons of surface mass in a single day, which was enough ice to cover the Florida in two inches of water.

However, this extreme melting event occurred with temperatures above 68 degrees.

But it was 2019 that broke all melting records so far.

Researchers from the Center for Polar and Marine Research found that the ice sheet lost 532 gigatons of overall mass, 15% more than the previous record holder, 2012.

And Scambos told USA Today that more melting is coming.

“We can expect 100 billion tons of water to pour into the ocean. Greenland as a whole is losing a huge amount of ice every year now,” he said.

SEA LEVELS COULD RISE UP TO 4 FEET BY THE YEAR 2300

Global sea levels could rise by up to 1.2 meters (4 feet) by 2300, even if we meet the Paris climate targets in 2015, scientists have warned.

The long-term change will be driven by a thaw of the ice from Greenland to Antarctica which is expected to reshape the world’s coastlines.

Sea level rise threatens cities from Shanghai to London, low-lying areas from Florida to Bangladesh, and entire nations like the Maldives.

It is vital that we reduce emissions as soon as possible to avoid an even bigger increase, a German-led research team has said in a new report.

By 2300, the report predicted that sea levels would rise by 0.7 to 1.2 meters, even if nearly 200 countries fully meet the targets of the 2015 Paris Agreement.

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

Ocean levels will rise inexorably because the heat-trapping industrial gases already emitted will linger in the atmosphere, melting more ice, he said.

Additionally, water naturally expands when it warms above four degrees Celsius (39.2°F).

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

“Sea level is often communicated as a very slow process that you can’t do much about…but the next 30 years really matters,” said lead author Dr Matthias Mengel of 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 deliver on their promises.
