As I have been saying for most of the last decade (including two days ago) climate scientists are incompetent hacks who have no clue how to interpret gravity data.
NASA glaciologist Jay Zwally first challenged the “consensus” on Antarctica in 2015 when he published a paper showing ice sheet growth in eastern Antarctica outweighed the losses in the western ice sheet.
Narrative - Warming - South - Pole - Zwally
Zwally will again challenge the prevailing narrative of how global warming is affecting the South Pole. Zwally said his new study will show, once again, the eastern Antarctic ice sheet is gaining enough ice to offset losses in the west.
So, why is there such a big difference between Zwally’s research and what 80 scientists recently published in the journal Nature?
Reasons - Disagreement - Researchers - Adjustment - GIA
There are several reasons for the disagreement, but the biggest is how researchers make what’s called a glacial isostatic adjustment (GIA), which takes into account the movement of the Earth under ice sheets.
Scientists use models to measure the movement of land mass in response to changes the ice sheet sitting on top. For example, Zwally said eastern Antarctica’s land mass has been going down in response to ice sheet mass gains.
Movement - Effects - Sheet - Data - Antarctica
That land movement effects ice sheet data, especially in Antarctica where small errors in GIA can yield big changes ice sheet mass balance — whether ice is growing or shrinking. There...
