Earth Just Permanently Passed Climate Threshold

Carbon dioxide concentration in the atmosphere stayed above 400 parts per million (ppm) during September—a time when CO2 levels typically hit the yearly low—raising fears that the planet has reached a point of no return.

"Concentrations will probably hover around 401 ppm over the next month as we sit near the annual low point. Brief excursions towards lower values are still possible but it already seems safe to conclude that we won't be seeing a monthly value below 400 ppm this year—or ever again for the indefinite future," Ralph Keeling, director of the CO2 program at Scripps Institution of Oceanography, wrote in a blog post.

The increase in CO2 levels runs parallel to a marked increase in global temperatures.

Is Winter Miserable for Wildlife?

By Bridget B. Baker

While the weather outside may indeed get frightful this winter, a parka, knit hat, wool socks, insulated boots and maybe a roaring fire make things bearable for people who live in cold climates. But what about all the wildlife out there? Won't they be freezing?

Anyone who's walked their dog when temperatures are frigid knows that canines will shiver and favor a cold paw—which partly explains the boom in the pet clothing industry. But chipmunks and cardinals don't get fashionable coats or booties.

Marine Mammals and Turtles Protected by the Endangered Species Act Are Bouncing Back

The Endangered Species Act works. That's the conclusion of a peer-reviewed study undertaken by scientists at the Center for Biological Diversity and published in PLOS ONE Wednesday.

The study looked at 31 populations of 19 species of marine mammals and sea turtles in the U.S. that had been granted endangered species protections and found that around three-quarters of them had increased in size.

A New Diet for the Planet

By Tim Radford

An international panel of health scientists and climate researchers has prescribed a new diet for the planet: more vegetables, less meat, fresh fruit, whole grains and pulses, give up sugar, waste less and keep counting the calories.

And if 200 nations accept the diagnosis and follow doctor's orders, tomorrow's farmers may be able to feed 10 billion people comfortably by 2050, help contain climate change, and prevent 11 million premature deaths per year.

This State Might Require Public Schools to Teach Climate Change

Reading, writing, arithmetic ... and climate science. That doesn't have the same ring as the "three Rs" of education, but Connecticut could one day require the subject to be on the curriculum, The Associated Press reported.

A Connecticut state lawmaker is pushing a bill to mandate the teaching of climate change in public schools throughout the state, starting in elementary school.
