The new annual data on Amazon deforestation in Brazil has just come out, and it’s good news. For the latest year—August 2013 through July 2014—the annual total was 4,848 square kilometers. That’s 18 percent less than in the previous year, and the second-lowest figure ever. Read More

In the worst kept news since the disclosure that Israel keeps an arsenal of nuclear weapons, the Environmental Protection Agency (EPA) announced this week its widely expected approval of Enlist Duo™, the latest class of herbicide designed for use with herbicide-resistant corn and soybeans.

I’m now in Bonn at the United Nations climate negotiations, where the big news is that in the last week the world’s two biggest emitters – China and the United States – have announced important actions to cut their carbon pollution, especially from the coal that they burn. These steps are welcome, but they are plans, not accomplishments, and they come late compared to other countries that have already acted to reduce their carbon dioxide emissions.
Ironically, most of these successes are in tropical developing countries, where countries’ reductions in rates of deforestation and in some cases their reforestation of cleared land have cut their net emissions of global warming pollution. Their actions have already accomplished more for the climate than the actions of many developed nations have.

Farmers and foresters already face a great deal of uncertainty in their professions. All it takes is a few weeks of intense drought, a single hailstorm, or an uncontrolled wildfire to destroy the results of their labors, and with it, their livelihoods. Read More

For quite a while, agriculture was dismissed as a possible way to mitigate climate change, because it’s where our food comes from, and we can’t live without food. From this obvious fact came the misinterpretation that we couldn’t cut agricultural greenhouse gas emissions without threatening food security. Read More

One small but important breakthrough in the new IPCC report on climate mitigation, released Sunday in Berlin, is that the chapter on agriculture, forest, and other land use (AFOLU) looks at the demand side, not just supply. In other words, it not only asks how we can create less global warming pollution in producing food and wood products, but also what kinds of food and wood products we ought to be producing and consuming if we want to avoid catastrophic climate change.

The taxman cometh. At my house, the 1040 is signed and the check is written, joining millions of others in the mail this week. Recently, the U.S. Treasury Department reported that improvement in the U.S. economy is leading to rising revenues from federal taxes. But just what are our tax dollars buying? Read More

I’m in Berlin at the Global Land Project conference, a biennial gathering of about 1000 scientists who study how we Earthlings use our world. I gave a talk on beef compared to other meats in the informal “Pecha Kucha” format, which requires you to use only 20 slides, each displayed for only 20 seconds. It was fun, but the big excitement has been hearing new ideas presented by researchers from all over the world.

History is happening all the time, but usually without us realizing it. Only rarely do we experience a change so dramatic that we know that what’s happening today will be remembered fifty or a hundred years in the future. The kind of thing that you’ll tell your grandchildren about. This is especially the case for so-called “tipping points,” celebrated in both scientific and popular writing. Usually, you only realize that something was a tipping point after you’re well past it. But sometimes…
