In the summer of 2019, Greenland received considerable media attention for two developments: Its large ice sheet saw record rates of surface melt with potentially devastating impacts on the oceans, and Donald Trump suggested that the United States should look into buying the island from Denmark. Although Greenland is not for sale, the Greenlandic government welcomes foreign investment and assistance in meeting the island's socio-economic challenges. The United States can also assist Greenland by improving international scientific cooperation on climate change research, helping Greenlanders adapt to a changing climate, and providing global leadership in addressing and mitigating the effects of climate change.
