Justify your assumption that the icecaps over Greenland will melt.
Global average temperatures the past ten years have decreased. Before that, over the entire previous century, they rose - AND FELL - continuously over the same 1/2 of one degree range.
Today, global temperatures are 2/10 of ONE degree higher than baseline - and that “baseline” was at the one of the coldest periods in the entire century.
Greenland ice is stable, increasing in the center of the island. Recent melts near the edge have stopped ( in places), reversed (in places) and been steady (in places.) Antarctica ice in increasing.
You need to read more carefully. I did not assume anything about Greenland melting. What I said was “IF it melts, and it has a lot of people worried.” Hardly an assumption, rather a conjecture.
