Bone-chilling cold and Arctic winds gripped the northeastern US last month. Data shows that the 2 operating utility-scale offshore wind farms on the East Coast—South Fork Wind & Vineyard Wind—performed as well as gas-fired power plants and better than coal-fired facilities during the severe storms.

Is climate change putting the Winter Olympics on thin ice? Winter is getting shorter. The best snow/ice is near the North & South Poles, which are warming the fastest. Warming means skiing on slush or artificial snow, and skating on melting ice or on indoor rinks. Poor conditions impact both...

“The past warming rate is no longer a reliable predictor of the future." From 1970 to 2010, global warming proceeded at a fairly steady rate: ~0.19°C/decade. Then the warming rate ticked up over the past decade: ~0.27°C/decade, or a 42% increase.

Elephant trunks can push over 900 lb trees yet pick up a tortilla chip without breaking it, sense ground vibrations from far-off herds, solve puzzles, craft tools, and much more. How? The 100s of whiskers on an elephant’s trunk are some of the most sophisticated and sensitive in the animal kingdom.
