How many more days annually cause ice melt in the current trend of global warming?

Question

32F or 0C is melting point of natural ice.
The current trend is average increase of .72F or .4C from early 80s to present time.

Vermont farmers have already harvested Maple syrup two weeks earlier than years ago.

University of Washington and Bristish Columbia in recent research estimated
most ice cap in arctic would be gone by 2040, 4 times faster than previous thought.

Answer 1

on this side selbs NASA confirmed it .

Answer 2

The freezing point of ice in polar waters is actually a couple of degrees colder than OC due to the colligative properties of brine (seawater) That is why the floating ice often melts before land based ice. Most polar ice is NOT melted by atmospheric heat or the subsequent transfer of heat to the sea surface, it is regulated through the thermohaline conveyor which constantly circulates warmer waters to the polar regions then subducting the cooled, denser waters deep into the oceans.

It would be an oversimplification to come up with a global number of "melt" days, there is too much regional variation. For instance, take a look at the latitude of Vermont vs Great Britain and tell me who has the greater number of "melt" days.

Answer 3

I'm not sure what the question says. It's not well written

The link might help you. Ironically, by 2100 the only ice left in the Northern hemisphere at the end of each summer (sept globe) will be in Greenland. It seems on the spring globe to be little change, but you have to understand that it represents the presence of ice, not the thickness. The volume of arctic ice is diminishing while the surface area may be the same size.
