Satellite measurements: Greenland, Antarctica Melting Six Times Faster Than in the 1990s

[essentialsaltes]

Observations from 11 satellite missions monitoring the Greenland and Antarctic ice sheets have revealed that the regions are losing ice six times faster than they were in the 1990s. If the current melting trend continues, the regions will be on track to match the "worst-case" scenario of the Intergovernmental Panel on Climate Change (IPCC) of an extra 6.7 inches (17 centimeters) of sea level rise by 2100.

The findings, published online March 12 in the journal Nature from an international team of 89 polar scientists from 50 organizations, are the most comprehensive assessment to date of the changing ice sheets. The Ice Sheet Mass Balance Intercomparison Exercise team combined 26 surveys to calculate changes in the mass of the Greenland and Antarctic ice sheets between 1992 and 2018.

The assessment was supported by NASA and the European Space Agency.

"Satellite observations of polar ice are essential for monitoring and predicting how climate change could affect ice losses and sea level rise," said Ivins. "While computer simulations allow us to make projections from climate change scenarios, the satellite measurements provide prima facie, rather irrefutable, evidence."

Ya and then some day the earth will be all covered in ice again and it starts all over. The south pole was once tropical with dinosaurs according to some folks. Nobody ever suspects this stuff isn't about us, it's been going on forever.

Maybe you can go camping up there pretty soon.

Many might not understand that wording, since it's a detail about an extra rise.... I think that's Not clear enough.

This can help:

"...experts concluded that even with lowest possible greenhouse gas emission pathways, global mean sea level would rise at least 8 inches (0.2 meters) above 1992 levels by 2100. With high rates of emissions, sea level rise would be much higher, but was unlikely to exceed 6.6 feet higher than 1992 levels."

Summer melting of ice in Greenland is again out of the ordinary. Apparently not as large in volume as the summer of 2019, but reaching a larger spatial extent by area.

It's the third instance of extreme melting in the past decade, during which time the melting has stretched farther inland

Ice melts, it melts in my glass, it melts in my cooler, it melts in my yard, it even melts in the mountains. And the whole fake concern over the so called "ice sheets" just look at the names of these places, Greenland, wow, sounds it should be a frozen wasteland but it's name proves it was once green and perfect for human settlement. And Antarctica, or broken down, Anti- Artic, meaning warm and ice free.
Ever since the 1970s with the "global cooling" hoax so called climate scientists have been backpedaling. They are even making unqualified children the policymakers.

How humid air, intensified by climate change, is melting Greenland ice
A new study highlights how warm, moist air invaded Greenland in 2021 to cause widespread melting, an increasingly common occurrence over the past decade

Jason Box waited for the skies to clear. The climatologist’s team was already in southern Greenland to begin their research project, but he was stuck in Nuuk, the country’s capital, because weather delayed his travels. Dark clouds loomed overhead, while the patter of rain echoed loudly as it fell onto the ocean.

Unbeknown to him, this same weather system was causing a historic melt event 660 miles away at the summit of Greenland. On Aug. 14, 2021, the system drew exceptionally warm and moist air from southern latitudes northward, increasing temperatures around 32 degrees (18 Celsius) higher than normal. Rain, not snow, fell on Greenland’s summit for the first time on record. Melting persisted over the next two weeks, covering 46 percent of the ice sheet. This was the largest melt event to occur so late in the year.

In a study released Thursday, Box and his colleagues illuminate how an atmospheric river caused the August 2021 melt event and brought rain to the summit. The explanation foretells a future that could be increasingly common as global temperatures rise due to human-caused climate change, accelerating sea level rise.

It's striking to me how this still somehow surprises people that their ocean front homes on the beach are going to go, soon...:

Maybe you can go camping up there pretty soon.

1) When you say "some day", precisely how long from now will that be?
2) It's not "some people" who say that, it is the evidence they collected that said that.
3) How do you believe that shifting climate (And therefore weather patterns) will affect humanity? Do you ONLY believe it will be positive and helpful so that we can go to beaches or COULD you see SOME people MAYBE getting negatively affected by climate change?
4) When you say "camping up there" do you mean way DOWN in Antarctica?
