callit quits in early winter. They keep blooming through snow showers, frost crackles, and quick melts . . . always with a pensive face. What became of all my Japanese beetles, those polychrome hedonists who used to mate in flesh piles, while eating, atop the roses? I haven’t seen any for three years. But the number of Lyme ticks and other insects has soared. When I first moved to upstate New York decades ago, no Lyme ticks trickled through the grass; the cold climate was too hostile. They usually begin their blood-sucking on the white-footed mouse. Last summer’s prolonged sizzle reduced the acorn crop, a mouse staple, and with fewer mice to hitch rides on and use as all-purpose canteen-nursery-gadabout-vectors for disease, the pesky parasite ticks began hopping aboard more humans. At least that’s how it seemed; people venturing across a meadow inevitably returned with a Lyme tick in tow.
    Imagine if you arrived home from work one day to discover that your pet spaniel had morphed into a wolf. You know that dogs evolved from wolves that we domesticated and hybridized . . . you just didn’t expect to find one gnawing on the sofa leg. Something similar happened in my garden. A favorite yellow Canadian rose bush, well adapted to the cold climate, has been blooming faithfully and true for years. Like many other garden roses, it’s a hybrid produced by grafting domestic and wild strains together. However, last summer, the rose suddenly revealed its lurking Id. To my amazement, from its feral heart it launched flutelike canes of heavily-flowering, tiny white roses. The wild rose ribs sprang from the same trunk as the well-bred yellow tea rose ribs. It was like having Siamese twins, one of which was Neanderthal, the other Homo sapiens .
    Heaven knows what it will do this summer. Wild roses are hardier, better adapted to unstable temperatures. Will climate change favor one or the other? Will all of the domesticated roses run wild? A garden is always full of surprises. Last summer, for the first time in the decades I’ve lived here, my yard was a deafening amphibian rave, where hundreds of croaking frogs (especially the drum-eared bullfrogs, whose croak should really belong to a snoring bull, and thesmaller banjo-plucking green frogs), bleatingly love-sick, drowned out human conversation. This year all I expect is the unexpected.
    Canadian scientists warn of fewer backyard ice-skating rinks and frozen ponds in the future, and in some regions none at all, because of winter’s waning bite. This inspired geographers at Wilfrid Laurier University in Waterloo, Ontario, to found a website to track the effect of a warm climate on Canada’s tradition of thousands of icy flat playgrounds.
    “We want outdoor rink lovers across North America and anywhere else in the world to tell us about their rinks,” they urge on RinkWatch.org. “We want you to pin the location of your rink on our map, and then each winter record every day that it’s skateable. We will gather up all the information from all the backyard rinks and use it to track the changes in our climate.”
    Many of Canada’s legendary ice hockey players learned to skate on such tiny rinks, and Canadians hold them dear. An invisible thorn in the ozone layer can be denied, but when backyard hockey season is delayed, people notice.
    Not everyone is warming up. Jim River, Alaska, a grizzly bear’s backyard and a grizzled hiker’s paradise, set a record low of -80°F. Residents there said the air hurt wickedly to breathe; they could feel it grate on every cell inside the nose. Exposed skin and eyes burned. Spit froze before it struck the ground. Frostnip took its toll. After a short spell outside, as people stepped back indoors, eyeglasses fogged up and froze to the face.
    From Colorado to British Columbia, due to twenty years of unusually warm weather, spruce and pine bark beetles have chewed through four million acres of trees. This is fabulous for the bark beetles, but
