So-called benefits of global warming in Greenland

This morning I’ve found a short news about the benefits of global warming in Greenland. Just some thoughts:

– Is it right to say that human usually earn more benefits in hotter places? If yes then we, with our current technology, may have the tendency to exacerbate the global warming? And why not do the opposite way – develop technology for earning benefits in cold?

– The writing implies that the climactic transformation is because of the winter solstice, no anthropogenic climate change mentioned. So the word “global warming” does not seem to be appropriate here.  It should just be “climate transformation”.
