Interesting little things…

TD GIFs & Clips [data guzzler]

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!

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

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.

GIFs: Spanish Peaks Turn Tan (by NASA)

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.
