UCL-led study finds climate impact caused by growing space industry needs urgent mitigation

Green Car Congress

The rapidly growing space industry may have a greater climate effect than the aviation industry and undo repair to the protective ozone layer if left unregulated, according to a new study led by UCL and published in the journal Earth’s Future as an open-access paper. The space industry is one of the world’s fastest growing sectors.

MIT-led study suggests mobile-phone data provide a deeper picture of pollution exposure in urban settings

Green Car Congress

A study led by MIT researchers, focused on New York City, suggests that using mobile-phone data to track people’s movement provides an even deeper picture of exposure to pollution in urban settings than by studying air-quality levels in fixed places. —Nyhan et al. But that’s sensitive to where the [measuring] stations are.

MIT team finds lead levels higher in Indian Ocean than northern Atlantic and Pacific oceans

Green Car Congress

MIT researchers have discovered that lead concentrations in the Indian Ocean are now higher than in the northern Atlantic and northern Pacific oceans. The result, he says, is that the Indian Ocean has had less time than the Atlantic and Pacific to dissipate lead pollution.
