Lockdowns have improved air quality in major cities around the world, per nitrogen dioxide measurements mapped here by Steven Bernard. Most cities, anyway.
Data source: ESA Sentinel 5
Data was processed by Descartes Labs showing average pollution levels from Mar 1 to Apr 5 2020, compared with the same period last year.
Data was brought into QGIS and styled and then further design work was done in Adobe Illustrator

I wonder if these maps expose a lack of social distancing, continued work travel, etc., that could be correlated to hidden prevalence of the disease. For example, if little has changed in Teheran's and Moscow's NO₂ output, is that evidence that there's no lockdown and a lot more people are getting it (and dying of it) than they're admitting?
Another unusual pattern that differs from other cities: London, where the country/exurbs are markedly less polluted than usual but a small dense area in the center hasn't changed much at all.
I made a crude diffed version (below), showing the change in output for each city. Black means no improvement (bear in mind rural areas with little pollution to begin with), green means a little improvement, red means a lot of improvement
P.S. Had no idea what a choked hellhole Milan is.
Antti Lipponen of the Finnish Meteorological Institute created this troubling but unsurprising chart of almost 140 years of temperature anomalies by country. The data used was from the NASA GISS, Land Ocean Temperature Index. You can probably guess what will happen.

Considering the state of our world, it probably shouldn’t come as a surprise to find lots and lots of people pushed to their breaking point. Anxiety and stress are often constant companions during the best of times. But now, with fear and frustration running rampant, it’s easy to be subsumed by all the distractions and […]
Most of us aren’t constantly beset by poor posture. But all it takes is some subtle misalignment while you’re doing serious hours behind the wheel driving or working away at a desk to do a real number on your back. In fact, most of us are so unaware of the mechanics of good posture that […]
From ordering from Amazon to paying bills over the web to something as simple as bottled water, we’re all hooked on modern convenience. We can’t help it. There are just too many modern world advances that save us too much time not to become a creature of comfort and go the easy route. Even if […]
