How much snow falls on Greenland?

As our climate changes from enhanced greenhouse effect (i.e. global warming), the air now holds more moisture. Consequently, rainfall and snowfall intensity is increasing.

So, the question is what is the balance between increasing snow fall and increasing ice melt?

Professor Jason Box has been working to answer this question using a ski-based traverse on the Greenland Ice sheet in 2017. With some low tech measurements of how much does the snow weigh, he can check the high tech - satellites and climate models. The results revealed that although snowfall is important for building up glaciers, melting is still dominating and so the balance is negative
