The airport’s average subsidence rate is 1.7 millimeters a year (similar to the LaGuardia and Newark airports), but across JFK that varies between 0.8 and 2.8 millimeters a year, depending on the exact spot.

The finding suggests that far more fire ice is vulnerable to climate-induced melt than scientists realized, and it could be a significant source of planet-warming gas in the future. “It’s a very, very, very large source of carbon,” says Davies. “What we’re showing is there are routes for that carbon to be released that we … Read more
Mary Yap has spent the last year and a half trying to get farmers to fall in love with basalt. The volcanic rock is chock full of nutrients, captured as its crystal structure forms from cooling magma, and can make soil less acidic. In that way it’s like limestone, which farmers often use to improve … Read more
