Air pollution plunges in European cities amid coronavirus lockdown (jpost)
While early reports of dolphins swimming in Venice were proven false, the European Space Agency reports that air pollution dropped in three cities. "This is a first level estimate; some of these values have gone down by about 40% of the normal value... so a very drastic decrease," Josef Aschbacher, ESA Director of Earth Observation Programmes. "What you really see are the centers of this pollution… It is quite a good first level indicator of anthropogenic pollution coming from traffic and industry," added Aschbacher.
