Trees Offset Carbon Footprint, But Which Trees?

Trees trap and absorb carbon dioxide as they grow. That’s how they help remove carbon dioxide from the atmosphere, mitigating or reducing global warming. But a new study from the Carnegie Institution and the Lawrence Livermore National Laboratory suggests the effectiveness of this strategy depends heavily on where these trees are planted. Because tropical forests store large amounts of carbon and produce reflective clouds, they are especially good at cooling the planet. In contrast, forests in snowy areas can warm the Earth, because their dark canopy absorbs sunlight that would otherwise be reflected back to space by a bright white covering of snow. “Tropical forests are like Earth’s air conditioner,” says Ken Caldeira of Carnegie’s Department of Global Ecology. “When it comes to rehabilitating forests to fight global warming, carbon dioxide might be only half of the story; we also have to account for whether they help to reflect sunlight by producing clouds, or help to absorb it by shading snowy tundra.” —Julia Whitty

THE FACTS SPEAK FOR THEMSELVES.

At least we hope they will, because that’s our approach to raising the $350,000 in online donations we need right now—during our high-stakes December fundraising push.

It’s the most important month of the year for our fundraising, with upward of 15 percent of our annual online total coming in during the final week—and there’s a lot to say about why Mother Jones’ journalism, and thus hitting that big number, matters tremendously right now.

But you told us fundraising is annoying—with the gimmicks, overwrought tone, manipulative language, and sheer volume of urgent URGENT URGENT!!! content we’re all bombarded with. It sure can be.

So we’re going to try making this as un-annoying as possible. In “Let the Facts Speak for Themselves” we give it our best shot, answering three questions that most any fundraising should try to speak to: Why us, why now, why does it matter?

The upshot? Mother Jones does journalism you don’t find elsewhere: in-depth, time-intensive, ahead-of-the-curve reporting on underreported beats. We operate on razor-thin margins in an unfathomably hard news business, and can’t afford to come up short on these online goals. And given everything, reporting like ours is vital right now.

If you can afford to part with a few bucks, please support the reporting you get from Mother Jones with a much-needed year-end donation. And please do it now, while you’re thinking about it—with fewer people paying attention to the news like you are, we need everyone with us to get there.
