Greenland ice sheet thinning at alarming rate. Really!

So what! This is the usual climate change alarmism and hysteria!

When the Vikings discovered Greenland around 982 CE, they christened it Greenland, because it was lush green. This happened during the Medieval Warm Period (950 - 1250 CE).

And how much of this ice melting can be attributed to the AMOC?

"Joint research involving satellites from the European Space Agency (ESA) and NASA have uncovered extreme thinning occurring across the Greenland Ice Sheet. ..."

From the key points and abstract:

"Although fluctuations in ice sheet surface mass balance lead to seasonal and interannual elevation changes, it is unclear if they are resolved differently by radar and laser satellite altimeters. We compare methods of computing elevation change from CryoSat-2 and ICESat-2 over the Greenland Ice Sheet to assess their consistency and to quantify recent change. Solutions exist such that interannual trends in the interior and the ablation zone agree to within −0.2 ± 1.5 and 3.3 ± 6.0 cm/yr, respectively, and that seasonal cycle amplitudes within the ablation zone agree to within 3.5 ± 38.0 cm. The agreement is best in the north where the measurements are relatively dense and worst in the southeast where the terrain is rugged. Using both missions, we estimate Greenland lost 196 ± 37 km3/yr of volume between 2010 and 2022 with an interannual variability of 129 km3/yr.

Key Points

• Greenland Ice Sheet elevation change between 2018 and 2022 from CryoSat-2 and ICESat-2 was −11.4 ± 0.8 and −11.7 ± 1.3 cm/yr, respectively
• Ablation zone seasonal cycle amplitude between 2018 and 2022 from CryoSat-2 and ICESat-2 was 62.9 ± 26.5 and 59.4 ± 24.4 cm, respectively
• Volume change between 2010 and 2022 was −196 ± 37 km3/yr with an interannual variability of 129 km3/yr

Greenland ice sheet thinning at alarming rate

ESA and NASA satellites deliver first joint picture of Greenland Ice Sheet melting "Global warming is driving the rapid melting of the Greenland Ice Sheet, contributing to global sea level rise and disrupting weather patterns worldwide. Because of this, precise measurements of its changing shape are of critical importance for adapting to climate change.

Now, scientists from the UK Centre for Polar Observation and Modelling have delivered the first measurements of the Greenland Ice Sheet’s changing shape using data from ESA’s CryoSat and NASA’s ICESat-2 ice missions."

Meltwater from Greenland and the Arctic is weakening ocean circulation, speeding up warming down south
