WebAbstract. Wind-blown dust (WBD) emitted by the Earth’s surface due to sandblasting can potentially have important effects on both climate and human health via interaction with solar and thermal radiation, reducing air quality. Apart from the main dust “centres” around the world, like deserts, dust can be emitted from partly vegetated mid- and high-latitude … Web215K views, 5.3K likes, 555 loves, 524 comments, 2.9K shares, Facebook Watch Videos from Elon Musk Zone: This will Change Everything You Think You Know..
