Researchers at NYU Abu Dhabi, along with other global scientists, have identified a new mechanism by which warm dust travels from the Sahara Desert to the Arctic Circle, which has been proven to affect rising temperatures and ice melt in Greenland. Their findings highlight the role that the polar jet and associated atmospheric circulation plays in the transport of mineral dust from the Sahara Desert to the Arctic across the eastern side of the North Atlantic Ocean.

NASA’s Land Vegetation and Ice Sensor has yet to leave the atmosphere, but that’s the long-term plan for this high-flying mapping technology. In the nearer future, LVIS will produce high-resolution, three-dimensional maps of Earth’s unexplored polar regions, allowing scientists to follow changes in ice cover more accurately than ever before. Since 1998, LVIS has mapped rainforest canopies in Costa Rica, surveyed Gulf Coast ocean topography, and even tracked ivory-billed woodpeckers …
