During the COVID 19 crisis, we saw images we never imagined: the transparent waters in Venice, a hole in the ozone that has closed, and cities with more breathable air. Some call it "the COVID paradox" and transport is the big explanation
It is an image that even in our greatest dreams we could not have in our heads: the air is purer, the ozone layer has closed, the corals have recovered their colors and the animals are... where they had always been until we arrived.
The data on air pollution and CO2 emissions say, again, that the quarantine the world is under to curb COVID-19 has a positive impact on air quality.
Images captured by the Royal Dutch Meteorological Institute (RKMI) with data from the Copernicus Atmospheric Monitoring Service show the strange effect of the new coronavirus: it affects us humans with respiratory and vascular disease, but it contributes to improved air quality and better breathing.
The Dutch agency measured nitrogen dioxide (NO2) emissions from March 14-25, 2020 and has compared it to the same period in 2019.
Less transport and less production have achieved what humans have been trying to do for at least 30 years: reduce CO2 emissions.
In countries where economic activity has been stopped or slowed down by the coronavirus, people are breathing better as a result of reduced air pollution.
The images from NASA satellites speak for themselves: in February, the concentration of nitrogen dioxide (NO2), produced mainly by vehicles and power plants, fell dramatically in Wuhan, the epicentre of the Covid-19 epidemic. From red/orange, the map turned blue. The question is, will we be able to keep this up once the pandemic is over?
