NASA and European Space Agency (ESA) pollution monitoring satellites have detected significant decreases in nitrogen dioxide (NO2) over China. There is evidence that the change is at least partly related to the economic slowdown following the outbreak of coronavirus.
At the end of 2019, medical professionals in Wuhan, China, were treating dozens of pneumonia cases that had an unknown source. Days later, researchers confirmed the illnesses were caused by a new coronavirus (COVID-19). By January 23, 2020, Chinese authorities had shut down transportation going into and out of Wuhan, as well as local businesses, in order to reduce the spread of the disease. It was the first of several quarantines set up in the country and around the world.
The maps on this page show concentrations of nitrogen dioxide, a noxious gas emitted by motor vehicles, power plants, and industrial facilities. The maps above show NO2 values across China from January 1-20, 2020 (before the quarantine) and February 10-25 (during the quarantine). The data were collected by the Tropospheric Monitoring Instrument (TROPOMI) on ESA’s Sentinel-5 satellite. A related sensor, the Ozone Monitoring Instrument (OMI) on NASA’s Aura satellite, has been making similar measurements.
“This is the first time I have seen such a dramatic drop-off over such a wide area for a specific event,” said Fei Liu, an air quality researcher at NASA’s Goddard Space Flight Center. Liu recalls seeing a drop in NO2 over several countries during the economic recession that began in 2008, but the decrease was gradual. Scientists also observed a significant reduction around Beijing during the 2008 Olympics, but the effect was mostly localized around that city, and pollution levels rose again once the Olympics ended.
It doesn’t take a disaster or even an emergency – beyond the one we have already created with the usual emissions levels. Reductions are possible. Disasters and loss are not mandatory, though we do make them inevitable to some extent by doing nothing. Still, these dramatic images should be instructional about what’s possible. It would be interesting to know the near-term implications of these reductions. You know, science.
Over the course of working on a piece about a Swedish film director from the 70’s, I’ve been writing and thinking about the various forms of erotica, as proffered on film in this instance. On the wings of this spilling over into conversations with known associates, a friend passed this on to me. Though it’s talking about art, aren’t we always?
The connection between pornography and prostitution is witnessed by etymology. The effect of pornographic fantasy is to ‘commodify’ the object of desire, and to replace love and its vestigial sacraments with the law of the market. This is the final disenchantment of the human world. When sex becomes a commodity, the most important sanctuary of human ideals becomes a market, and value is reduced to price. That is what has happened in the last few decades, and it is the root fact of post-modern culture.
Sentimentality, like fantasy, is at war with reality. It consumes our finite emotional energies in self-regarding ways and numbs us to the world of other people. It atrophies our sympathies, by guiding them into worn and easy channels, and so destroys not only our ability to feel, but also our ability to bring help where help is needed and to take risks on behalf of higher things. It may seem to project and endorse a vision of those higher things, to take on itself some of the ennobling function which is the imagination’s proper task. But the appearance is an illusion. The object of sentimental emotion is in fact dragged down by the feeling which makes use of it, made grubby and tawdry in the game of emotional exchange. Sentimentality is another form of profanation. While pornography puts our lowest appetites on sale, sentimentality trades in love and virtue. But the effect is the same -to deprive these higher things of all reality, either by cynically denying them, or by making them insubstantial, dream-like, adrift in a never-never land where no human being can dwell. In the great works of imagination, by contrast, we are invited to enter a higher realm, in which real human motives and real human sentiments find their resolution and redemption. This higher realm is not a fantasy-product: it is not the surrogate object of base and existing desires. It is the true object of feelings which it itself engenders, and whereby it cleanses and sanctifies our lives.
It’s not long, so you should read the whole thing. Thanks, ac.
