When days lengthen and ice begins to melt, Professor David Holland and his team of researchers head for an unlikely summer destination — Greenland. Holland, principal investigator of NYU Abu Dhabi's Center for Sea-level Change, works to understand how marine-based ice sheets will contribute to rising sea levels in an age of global climate change. Greenland, which is home to a massive glacier, is a critical site for the Center's work. Check out the photos below from a recent trip to this giant island of the north.
