There is a little bit of buzz lately of China’s ascendance, even on innovation. And here are a couple of numbers from a NYT article about urban China leapfrogging on mobile payments (2016 data via iResearch):

112
United States ($ billion)
5500
China ($ billion)

This, below, is my personally preferred way of looking at this, thanks to GIF and data visualization and things that I love doing at TD Bank now:

Air Quality Action Day? Worry Not, NYers!

Michael Animation, Data & Graphics, Photo, Video July 22, 2017

If you have never heard of an air quality action day, you are most likely a perfectly typical resident in the U.S. who is also lucky, the latter of which you may have been taking for granted. Because a hazy day like July 20, 2017 in Manhattan almost never happens. (Hazy is not the same as “foggy.”)

GIFs: California Reservoirs From Drought to Deluge

Michael Animation, Data & Graphics, Photo April 20, 2017

A five-year drought in California ended spectacularly this winter, with the state emerging from one of its driest periods on record by enduring one of its wettest. Reservoirs, lakes, and mountainsides are now brimming with water and snow, though scientists caution that the unseen reservoirs—underground aquifers—are a long way from having the same bounty that is visible on the land surface.

Trinity Lake, the third largest reservoir in the state (after Lake Oroville and Shasta Lake). The artificial lake in northern California connects to the Trinity River and is part of the Sacramento basin. On April 29, 2015, Trinity stood at 59 percent of its historical average level for that date; by April 2, 2017, it stood at 114 percent.

GIFs: Shanghai Adds 10 Manhattans

Before I did my googling and math, I couldn’t believe it but here it is: Shanghai has added as much land as 10 Manhattans over the past couple of decades. Here are some satellite images as witness:

The number of people living in Shanghai is not the only thing about the city that has increased dramatically since the 1980s. The amount of land available to its residents has grown as well. By building seawalls just off the coast to capture outflowing sediment, and by using dredging equipment that sucks up and moves large volumes of sand, Shanghai has added well over 580 square kilometers (220 square miles) of land to its shorelines since 1985.

来自非洲撒哈拉大沙漠的沙尘千里迢迢洒在了西班牙的雪山上,山舞银蛇的景象不再,在滑雪爱好者眼中尤其大煞风景。【原文见NASA Earth Observatory

Two days after it was lofted into the air over the Sahara Desert on February 20, dust blew north into Spain and Europe. As dust particles settled down en masse on the snow-covered peaks of Spain’s Sierra Nevadas, they left the mountains a very different color. [GIF shows Feb. 18 – Feb. 27, 2017.

Red Alert for Beijing Air Looks More Like Orange on NASA Map

北京12月中的空气污染红色警报再次牵动了大家脆弱的心肺,但是在NASA的空气污染色阶图中,北京天津似乎也就是个橙色级别,再看看石家庄才叫红得骄傲呢。NASA原文及滚动条互动图点这里

Smog was particularly bad in cities like Beijing, which declared a five-day pollution “red alert” on December 16. The Chinese capital reached dangerous levels of more than 400 micrograms per cubic meter. In Shijiazhuang, capital of the Hebei province, airborne pollutants surpassed World Health Organization (WHO) guidelines by 100 times on December 19. (A safe level is 10-25 micrograms per cubic meter of PM2.5, according to the WHO.)

Fine, airborne particulate matter (PM) that is smaller than 2.5 microns (about one thirtieth the width of a human hair) can cause lung damage. Industrial practices like fossil fuel burning and agricultural fires produce most PM2.5aerosol particles. Despite efforts to curb these emissions, China continues to struggle with its air quality.

From space, the smog appears gray. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite captured a natural-color image (top) of northeastern China on December 22, 2016. Heavy, gray smog shrouds parts of the country, while the brightest, whiter areas are likely clouds or fog. The second image shows the severity of haze as measured by satellite, with deepest reds indicating the most affected areas. The map is based on MODIS measurements of aerosol optical depth—how much sunlight the aerosol particles prevent from reaching the ground.
