Farmland birds don’t seem to mind wind turbines, says study

The sights and sounds of wind turbines don’t seem to bother farmland birds, according to research published in the Journal of Applied Ecology. Scientists studied the effects of two wind farms in eastern England on 3,000 birds of 23 species, and found that only pheasants seemed to be disgruntled enough to move farther away from […]

Solar PV + waste heat

Cool. The pursuit of usable waste heat is one of the great unheralded stories of the green shift.

Attention Catholics

Greenwashing our vegetable modifiers

A few weeks ago, I was having dinner at a renowned restaurant in San Francisco, when I noticed something a bit troubling on the menu. According to the description, the “Heirloom Tomato Salad” was made with a mix of Sweet 100 and Sungold tomatoes — both of which are hybrid varieties. OK, big deal, they […]

Cutting meat and milk consumption cuts CO2 emissions, study says

Happy World Vegetarian Day! Just in time for the festivities, a new study from the Food Climate Research Network finds that cutting down on meat and milk consumption can help cut greenhouse-gas emissions. The four-year study focused mainly on the U.K., concluding that dramatically cutting the average Briton’s weekly meat and milk intake could help […]

Bad news for climate change

In August alone, loggers and farm interests leveled 300 square miles of Amazon rainforest, the Brazilian government reports (via AP). That’s a land mass larger than greater Chicago — taken out in the span of a single month. It also represents a leap of 228 percent over August 2007’s destruction. Two observations: 1) Higher soy […]

New study finds sun’s contribution to recent warming is ‘negligible’

Earth to deniers — global warming is caused by human emissions, not solar activity. The Naval Research Laboratory and NASA report that, “if anything,” the sun contributed “a very slight overall cooling in the past 25 years.” D’oh! The study ($ub. req’d), “How natural and anthropogenic influences alter global and regional surface temperatures: 1889 to […]

Why scientists aren’t more persuasive, part 1

Of all the talents bestowed upon men, none is so precious as the gift of oratory. He who enjoys it wields a power more durable than that of a great king … The subtle art of combining the various elements that separately mean nothing and collectively mean so much in an harmonious proportion is known […]

Letterman rages on global warming

I am (slightly) less pessimistic than David Letterman. If, however, it is indeed “too late” as he says, then he has certainly nailed the reason: “We have had no leadership.” But I’m going to view the glass as one-tenth full and take it as a hopeful sign that somebody relatively mainstream like Letterman would break […]
