Is climate change just a hoax? It’s not … but why not follow Ronald Reagan’s advice and “trust but verify” by looking for evidence — pro or con — in your own backyard? If you pay attention to animals, plants and weather, you may discover that your neighborhood really is getting warmer.
Last Chance Dance in Plants
Flowers look so innocent. But just like humans, they can be manipulative and very picky about their mates, as illustrated by ladyslippers and irises, two common bumble-bee pollinated plants. (If you want to learn more, see Zink and Wheelwright, Amer. Midland Naturalist 137: 72-78.)
