Princeton University researchers reported that unless greenhouse gas emissions are curbed, marine biodiversity could be on track to plummet to levels not seen since the extinction of the dinosaurs. The study authors modeled future marine biodiversity under projected climate scenarios and found that species such as dolphinfish (shown) would be imperiled as warming oceans decrease the ocean’s oxygen supply while increasing marine life’s metabolic demand…

Taos Ski Valley in New Mexico recently became the first North American ski resort to use a fully-electric snow groomer, by putting a PistenBully 100 E into operation. This is just one of several actions the mountain village is taking to promote sustainability and achieve its pledge to reach net-zero carbon emissions by 2030. The mountain village was originally settled by copper miners in the 1800s, but was not founded as a ski area until the 1950s. Having been incorporated as a village in 1996, Taos Ski Valley…
