A strange phenomenon has emerged near Amazon.com delivery stations and Whole Foods stores in the Chicago suburbs: smartphones dangling from trees. Contract delivery drivers are putting them there to get a jump on rivals seeking orders.

Someone places several devices in a tree located close to the station where deliveries originate. Drivers in on the plot then sync their own phones with the ones in the tree and wait nearby for an order pickup. The reason for the odd placement, according to experts and people with direct knowledge of Amazon’s operations, is to take advantage of the handsets’ proximity to the station, combined with software that constantly monitors Amazon’s dispatch network, to get a split-second jump on competing drivers. That drivers resort to such extreme methods is emblematic of the ferocious competition for work in a pandemic-ravaged U.S. economy suffering from double-digit unemployment. Much the way milliseconds can mean millions to hedge funds using robotraders, a smartphone perched in a tree can be the key to getting a $15 delivery route before someone else. Drivers have been posting photos and videos on social-media chat rooms to try to figure out what technology is being used to receive orders faster than those lacking the advantage.

It was 116 degrees Fahrenheit in the shade outside the new Al Janoub soccer stadium, and the air felt to air-conditioning expert Saud Ghani as if God had pointed “a giant hair dryer” at Qatar. Yet inside the open-air stadium, a cool breeze was blowing. Beneath each of the 40,000 seats, small grates adorned with Arabic-style patterns were pushing out cool air at ankle level. And since cool air sinks, waves of it rolled gently down to the grassy playing field. Vents the size of soccer balls fed more cold air onto the field. Ghani, an engineering professor at Qatar University, designed the system at Al Janoub, one of eight stadiums that the tiny but fabulously rich Qatar must get in shape for the 2022 World Cup. His breakthrough realization was that he had to cool only people, not the upper reaches of the stadium — a graceful structure designed by the famed Zaha Hadid Architects and inspired by traditional boats known as dhows. “I don’t need to cool the birds,” Ghani said.

Qatar, the world’s leading exporter of liquefied natural gas, may be able to cool its stadiums, but it cannot cool the entire country. Fears that the hundreds of thousands of soccer fans might wilt or even die while shuttling between stadiums and metros and hotels in the unforgiving summer heat prompted the decision to delay the World Cup by five months. It is now scheduled for November, during Qatar’s milder winter. The change in the World Cup date is a symptom of a larger problem — climate change. Already one of the hottest places on Earth, Qatar has seen average temperatures rise more than 2 degrees Celsius (3.6 F) above preindustrial times, the current international goal for limiting the damage of global warming. The 2015 Paris climate summit said it would be better to keep temperatures “well below” that, ideally to no more than 1.5 degrees Celsius (2.7 F).

[…] To survive the summer heat, Qatar not only air-conditions its soccer stadiums, but also the outdoors — in markets, along sidewalks, even at outdoor malls so people can window shop with a cool breeze. “If you turn off air conditioners, it will be unbearable. You cannot function effectively,” says Yousef al-Horr, founder of the Gulf Organization for Research and Development. Yet outdoor air conditioning is part of a vicious cycle. Carbon emissions create global warming, which creates the desire for air conditioning, which creates the need for burning fuels that emit more carbon dioxide. In Qatar, total cooling capacity is expected to nearly double from 2016 to 2030, according to the International District Cooling & Heating Conference. And it’s going to get hotter.
