Hah I sadly missed it... I was happy to enjoy my sleep. Did you see it this morning?

The sun is indeed a HUGE powerhouse, but you must take into account that we are 149.600.000 km's away from it (93.000.000 miles) and we only receive 0.000000045% of the energy it produces. This puts the massive size of our sun into more perspective. I'm not of the opinion that the sun controls our climate rather than influences it.

Greenland has indeed been ice-free in past histories, so was Antarctica and everything on earth was fine because these changes happened gradually over millions years, or even thousands at least. Changes in climate on a global scale have never happend as sudden as they do now (only 100 years). And I looked a little deeper into the sources. The source from the first example of Greenland states this:

This budget takes into account the balance between snow that is added to the ice sheet and melting snow and glacier ice that runs off into the ocean. The ice sheet also loses ice by the breaking off, or “calving”, of icebergs from its edge, but that is not included in this type of budget. As a result, the SMB will always be positive – that is, the ice sheet gains more snow than the ice it loses.

it is no secret that increased warming causes more water to be stored in the atmosphere which can induce more snowfall, but it is the much greater effect of warmer ocean waters hitting the ice that causes ice berg calving. And since that is definitely equally as important the data of the study does not necessarily mean that the Greenland Ice sheet is growing
