A North American Climate Boundary Has Shifted 140 Miles East Due to Global Warming
Climate Change
The oceans’ circulation hasn’t been this sluggish in 1,000 years. That’s bad news.
"The Atlantic Ocean circulation that carries warmth into the Northern Hemisphere’s high latitudes is slowing down because of climate change, a team of scientists asserted Wednesday, suggesting one of the most feared consequences is already coming to pass."
"The Atlantic meridional overturning circulation has declined in strength by 15 percent since the mid-20th century to a “new record low,” the scientists conclude in a peer-reviewed study published in the journal Nature. That’s a decrease of 3 million cubic meters of water per second, the equivalent of nearly 15 Amazon rivers."
"The AMOC brings warm water from the equator up toward the Atlantic’s northern reaches and cold water back down through the deep ocean. The current is partly why Western Europe enjoys temperate weather, and meteorologists are linking changes in North Atlantic Ocean temperatures to recent summer heat waves."

Why Green Groups Are Split on Subsidizing Carbon Capture Technology – Yale E360
"A bipartisan group of U.S. lawmakers quietly passed a bill to bolster carbon capture and storage technology back in February. But environmentalists are split over whether the new law is actually a good or bad thing in the fight against climate change. Journalist Richard Conniff reports: https://e360.yale.edu/features/why-green-groups-are-split-on-subsidizing-carbon-capture-technology"
How Lyme disease became the first epidemic of climate change
"Evolution has endowed the big-footed snowshoe hare with a particularly nifty skill. Over a period of about 10 weeks, as autumn days shorten in the high peaks and boreal forests, the nimble nocturnal hare transforms itself. Where it was once a tawny brown to match the pine needles and twigs amid which it forages, the hare turns silvery white, just in time for the falling of winter snow. This transformation is no inconsequential feat. Lepus americanus, as it is formally known, is able to jump 10 feet and run at a speed of 27 miles per hour, propelled by powerful hind legs and a fierce instinct to live. But it nonetheless ends up, 86 per cent of the time by one study, as a meal for a lynx, red fox, coyote, or even a goshawk or great horned owl. The change of coat is a way to remain invisible, to hide in the brush or fly over the snow unseen, long enough at least to keep the species going."
