When general store owner Melchor Villanueva leans on his countertop he can see his whole world under his hands. The counter’s glass surface displays photos of his community: young soccer players, teens in their coming-of-age quince años finest, and bandanna-wearing fishermen. Many descend from survivors of Hurricane Janet, which in 1955 killed a third of the population of Xcalak, a beach town on the Mexico-Belize border, and destroyed the town’s coconut plantations. “It left only sand,” Villanueva recalls.

In mid-October 2016, officials from China’s Ministry of Environmental Protection counted five illegal trash-burning sites and hundreds of thousands of vehicles exceeding emission standards in Beijing alone. For the first time since last winter’s pollution high season, city officials issued a yellow air-quality alert, which required shutting down power plants and reining in Beijing’s frenetic factories and road traffic. If this winter is anything like past winters, the city will have to pull out the yellow card again—and may even have to reach for its red card.
Where there’s oil, there’s a way. This summer the federal government showed that it is willing to approve drilling operations in U.S. waters off Alaska. In addition to legislation, other barriers to Arctic development are disappearing: summers at the North Pole could be ice-free as soon as 2020, reducing the need for ice-breaking vessels and opening the way for faster and cheaper trading routes. An increase in shipping across the top of the world, however, could have “significant regional impacts by accelerating ice melt,” according to a recent government report by the Canadian Northwest Territories. And that aggravated melting could raise global sea levels. Continue reading
In late September, Volkswagen admitted to using software that activated hardware to scrub nitrogen oxide (NOx) emissions during required emissions tests, but not during normal driving. The deception improved the cars’ gas mileage at the cost of emitting between 10 and 40 times the legal limit of NOx, a precursor gas to nitrogen dioxide (NO2), ammonia (NH3), and other gases that cause respiratory problems. In the last few years, newly maturing instruments of several kinds have converged on a single message: diesel exhaust in the real world is far higher than what carmakers advertise and what is permitted by the law in many countries.
