I know the first two articles are about the same thing, but I think they say it differently enough, and it’s important. As much as a pain as these recent snowstorms have been, they don’t disprove global warming.

• Another Blizzard: What Happened to Global Warming? – Time. Warmer air holds more moisture, which leads to more snowfall.
• Bundle Up, It’s Global Warming – New York Times. More moisture in the air = more snow in Siberia = a change in the jet stream? (Thanks, Lesley!)
• Don’t fear riding a bicycle, fear sitting in that chair – Grist. “The health benefits of bicycling are nine times greater than the safety gains from driving.”
• Making biking in the city safer – Boston Globe. I would love to have European-style bike lanes in Boston.
• Does Recycling Your Toothbrush Really Make a Difference? – Treehugger. In a word, yes.
• Green building – Boston Globe. Apparently there are rival factions in environmental urban planning: new urbanism and landscape urbanism.
• Canton dump may soon be a solar powerhouse – Boston Globe. “The project . . . would be three times larger than any other solar facility up and running in New England.”
• Efficiency could cut world energy use over 70 per cent – New Scientist. Of course, this is drastic efficiency, like PassivHaus designs and super-light cars.
• Agreement to cut power plant discharge, send steam heat to Boston – Boston Globe. “The pipe will be completed at the latest by 2016 — when reconstruction of the Longfellow Bridge is scheduled to be finished.”
• Once Popular, Car Pools Go the Way of Hitchhiking – New York Times. It’s tough. Jason’s coworker Raj lives across the street from us, but they keep different hours, so they don’t carpool.
• Green Communities Act – Energy 2.0. The Green Communities Act provides grants to cities that meet five criteria, including adopting the stretch code and reducing municipal energy use by 20%.
• The Best Investment Under the Sun? – Slate. Solar hot water heaters are cheaper and break even sooner, but photovoltaic panels are a better long-term investment.
• Beyond Salads: Planting a Garden to Feed a Family – Treehugger. Calorie crops like potatoes, corn, beans, and squash go farther than lettuce and tomatoes.

That’s it. As always, if you find anything interesting this week, send it along.
