Cate McQuaid, my favorite Boston Globe art critic, who usually covers more esoteric subjects, explains some large artsy globes seen around Boston in recent days.

“Huge, colorful orbs line up in a row down the Tremont Street side of Boston Common. It looks like a giant might be marshaling his marbles. Get up close, and you’ll see that the spheres, each 5 feet in diameter, are globes, fancifully decorated and proffering solutions to climate change.

“ ‘Cool Globes: Hot Ideas for a Cooler Planet’ has landed in Boston. The public art project, for which artists designed globes with green strategies to contend with environmental issues, originated in Chicago in 2007 and has traveled the world.”

Environmental activist Wendy Abrams, says McQuaid, is the initiative’s founder.

“Abrams cites two inspirations for the project, the wrecked cars that Mothers Against Drunk Driving pointedly deploy in their Crash Car Program, and the painted cow sculptures that showed up in the streets of Chicago in 1999 — a public art project that prompted Boston to follow suit with painted cod.”

Read about individual artists’ Cool Globe themes, the outreach to students, and more, here.

The first two photos below are near the Park Street subway station. The third is in front of the aquarium, and I am not sure if it is part of the traveling series.

At Public Radio International’s “The World,” David Leveille has a story on research at Ellesmere Island in northern Canada.  There, University of Alberta biologist Catherine La Farge is finding that some frozen plants are able to begin growing again after 400 years on ice.

“Cold as it may be during the winter,” writes Leveille, “it’s a part of the world where glaciers are melting and ice sheets are breaking up due to climate change.

“One glacier there is called the Tear Drop glacier. As it has melted, some interesting plant life was exposed.”

La Farge’s results, published in the Proceedings of the National Academy of Sciences “suggest that bryophytes, representing the earliest lineages of land plants, may be far more resilient than previously thought, and likely contribute to the establishment, colonization, and maintenance of polar ecosystems.” Who knows what else is under the glacier and about to be thawed out.

When you take pretty much the same walk every day, camera in hand, you may have trouble finding new things to photograph. You may look in vain for something different, puzzling, or mysterious.

But there is something to be said for combing the same territory over and over, as scientists are finding from studying the detailed record keeping of Henry David Thoreau.

“ ‘As far as I know, there is more information about the effect of climate change in Concord than any other place in the United States,’ said Richard Primack, a Boston University biologist who calls Concord a living lab for his research. …

Primack, writes Kathleen Burge at the Boston Globe, “has researched how climate change has affected the flowering times of plants, comparing modern data with the information Thoreau collected between 1852 and 1860. Primack and his lab found that for every 1 degree Celsius increase in mean spring temperature, plants bloom about three days earlier. …

“Primack came to his work about a decade ago, when he decided to change the direction of his research. He had been studying the effects of climate change on plants and animals in southeast Asia and decided, instead, to focus on his home state.

“But when he began searching for older records of plant flowering times in the United States, he came up short. Finally, after six months, someone told him about Thoreau’s journals.

“This was kind of a gold mine of data,” Primack said. “As soon as we saw it, we knew it was amazing.” More from the Globe.

Keep an eye open for the upcoming Thoreau exhibit at the Concord Museum April 12 to September 15, described here.

Happy President’s Day! Why are you working?

​According to Mother Jones, economist David Rosnick has “found that dialing back the amount of time the average person works by 0.5 percent per year would mean a significant reduction in greenhouse gas emissions. If you work 40 hours a week, that would mean shaving about 12 minutes off the average work week per year. Working one minute less per month seems pretty doable. Basically, we’re using a whole lot more of everything when we’re working – electricity, gasoline, heating, air conditioning, etc. Leisure requires less greenhouse-gas-producing activity.”

I forget were I found this story first, but you can read more at Mother Jones, here.

Hurricane Sandy was terrible for many communities in its path, and the devastation has given urgency to climate concerns and innovative solutions.

Henry Fountain writes about one such solution in the NY Times, “With a few dull thuds, the one-ton bag of high-strength fabric tumbled from the wall of the mock subway tunnel and onto the floor. Then it began to grow. As air flowed into it through a hose, the bundle inflated until it was crammed tight inside the 16-foot-diameter tunnel, looking like the filling in a giant concrete-and-steel cannoli.

“The three-minute procedure, conducted on a chilly morning this month in an airport hangar not far from West Virginia University, was the latest test of a device that may someday help guard real tunnels during disasters — whether a terrorist strike or a storm like Hurricane Sandy, whose wind-driven surge of water overwhelmed New York City’s subway system, shutting it down for days.

“ ‘The goal is to provide flooding protection for transportation tunnels,’ said John Fortune, who is managing the project for the federal Department of Homeland Security’s Science and Technology Directorate.

“The idea is a simple one: rather than retrofitting tunnels with metal floodgates or other expensive structures, the project aims to use a relatively cheap inflatable plug to hold back floodwaters.

“In theory, it would be like blowing up a balloon inside a tube. But in practice, developing a plug that is strong, durable, quick to install and foolproof to deploy is a difficult engineering task, one made even more challenging because of the pliable, relatively lightweight materials required.”

Living on Earth, a radio show based in Somerville, Massachusetts, and distributed by Public Radio International, recently did a story on East Africa and the worst drought in 60 years. Bobby Bascomb interviewed musicians who decided to do something about it, letting their voices be heard in the way they know best.

They call themselves the Caravan of Hope, says Bascomb. “More than 25 bands from 11 different African nations are traveling across the continent to raise awareness about climate change … as international climate talks begin in Durban, South Africa.”

Singer Angella Katatumba of Uganda explains, “We use our voices to get people fired up and educate people about climate change in Africa. Uganda usually has an amazing climate. It’s usually warm and just perfect. These days, when it’s hot it’s way too hot. When it’s cold it’s way too cold. When it’s wet, it’s storming. We’re seeing things like landslides, which we’ve never had before.” So she’s taking her concern on the road. Read more here.
