Great Salt Lake’s retreat poses a major fear: poisonous dust clouds

The largest salt lake in the western hemisphere risks ‘one of the worst environmental disasters’ as it faces the prospect of disappearing in just five years

To walk on to the Great Salt Lake, the largest salt lake in the western hemisphere which faces the astounding prospect of disappearing just five years from now, is to trudge across expanses of sand and mud, streaked with ice and desiccated aquatic life, where just a short time ago you would be wading in waist-deep water.

JD Vance says US needs control of Greenland to fend off China and Russia

Vice-president criticises Denmark’s treatment of Arctic island and says it should come under US ‘security umbrella’ JD Vance told troops in Greenland that the US has to gain control of the Arctic island to stop the threat of China and Russia as he doubled down on criticising Denmark, which he said “have not done a good job”. Under increasingly strained relations between the White House and Greenland and Denmark, the US vice-president said during a visit to Pituffik space base on Friday: “Our message to Denmark is very simple: You have not done a good job by the people of Greenland.
