“Many consider it a good indicator of the global warming trend due to its proximity to the Arctic and its being the only permanent ice sheet outside Antarctica.”
Say what?
To paraphrase nuzzlin’ joe: “Three words. It’s summer time up there.”
1. Define the “correct” temperature range for the planet.
2. Define the “correct” humidity range for the planet.
3. Define the “correct” mean sea level for the planet.
4. Define the “correct” amount of precipitation for the planet.
5. Define the “correct” makeup of the atmosphere.
6. Define the “correct” amount of sea ice at the N/S poles.
7. Define/explain past glaciation and subsequent warming without any input from humans.
No, the quote is correct. There is very little land ice in the north hemisphere - almost all of it in Greenland .
