Arthur T Knackerbracket has found the following story:

New data from the Copernicus Sentinel-5P satellite reveal the decline of air pollution, specifically nitrogen dioxide emissions, over Italy. This reduction is particularly visible in northern Italy which coincides with its nationwide lockdown to prevent the spread of the coronavirus.

The animation shows the fluctuation of nitrogen dioxide emissions across Europe from 1 January 2020 until 11 March 2020, using a 10-day moving average. These data are thanks to the Tropomi instrument on board the Copernicus Sentinel-5P satellite which maps a multitude of air pollutants around the globe.

Claus Zehner, ESA's Copernicus Sentinel-5P mission manager, comments, "The decline in nitrogen dioxide emissions over the Po Valley in northern Italy is particularly evident.

"Although there could be slight variations in the data due to cloud cover and changing weather, we are very confident that the reduction in emissions that we can see, coincides with the lockdown in Italy causing less traffic and industrial activities."

Josef Aschbacher, ESA's Director of Earth Observation Programmes, says, "Copernicus Sentinel-5P Tropomi is the most accurate instrument today that measures air pollution from space. These measurements, globally available thanks to the free and open data policy, provide crucial information for citizens and decision makers."

    Don't worry, the Sulfur Dioxide will make up for it.

    Evidence suggesting that the Chinese government is hiding the actual severity of the Wuhan coronavirus outbreak is piling up. Every estimate, whistleblower, and unconfirmed report suggest the actual number of coronavirus casualties is much higher than what the official data says.

    The bullshit is piled thick on this one.

    The Chinese government has shut down many major factories, coal-fuelled power plants, and manufacturing to curb the coronavirus outbreak. So there is little chance that they could be responsible for the rising levels.

    Unless, of course, restarting those major factories and such are what's causing the spikes in pollution.

      Russia kept an eye on china since forever and immediately closed the border, when the official position here was "just a rather pesky flu strain". The official position was wrong.

        That's supposed to be relevant how? And I'm not confident in either the Russian government's ability to close borders or reveal the true state of coronavirus infection in their country.

          It's a waste of time to be logic with you, but the fact that the borders were closed in the end of january is proof russians knew the situation was different from the official line. Whether russkies actually died or not is not relevant. Whether they efficiently closed the border is not relevant but I tend to think good ol' Russian paranoia helps there.

            You still have yet to say why that story is relevant. My point remains. There are multiple scenarios that result in sudden surges in air pollution, some coming from the relatively rosey reported numbers coming out of China - namely that industry is starting up again.

              The hypothesis was China is hiding something. If Russia closed borders in january when local politicians were joking about hugging chinese, it adds to the suppositions you cited as bullshit, to prove that Russians saw through the officials line. You don't shut down your borders and routes for nothing or mere suspicion, it costs. Now, if russians saw right, they either were very lucky, or misinformed in the right direction, or (the most probable) initially China understated the problem, first to themselves in the chain of command, then to outside. You can't blame them, Russkies did too (chernobyl) and everybody else.

                Just because China is hiding something doesn't mean that they're hiding thousands of deaths. And Russia's actions don't inform us as to actual risk from China presently.
