The reason that there is more snow falling on the top of the Greenland
ice-cap is simple enough - the vapour pressure of water increases with
temperature, so there is now more water vapour the in the air flowing
over Greenland. The Greenland glaciers don't melt, but rather slide
down into the sea, and that does proceed in fits and starts.
If you think that the consensus about global warming is artificial,
you clearly don't know much about the subject.
Some of these ideas should be easily testable. With a net melting
of glaciers--or sliding of land-ice into the sea--for example, sea
levels should rise. So, how much have they risen?
It's been 2 - 3 mm a year for ages. Mostly due to ocean warming AIUI. I did see some
numbers that suggested Greenland's ice was actually helping to LOWER that figure.
