This week marks the beginning of the annual U.N. climate negotiations in Bonn, chaired by the nation of Fiji, and this year it’s going to be different. At most of the negotiating sessions from the early 90s up to the Paris Agreement in 2015, the emphasis was, reasonably, on reaching a broad consensus on how to prevent dangerous climate change. But Paris achieved that, and all the world’s countries, with one exception—the United States—have accepted that agreement. So now the question is, how can we make it work? A real challenge—particularly since a key delegation to the talks is now led by the climate-denialist Trump administration.

As both scientists (in many published papers) and political leaders (in the Paris Agreement) have now recognized, to stop global warming—to keep the global temperature from increasing indefinitely—we need to peak and then reduce emissions rapidly. We need to get our release of global warming pollution into the atmosphere, down to a level below the amount that carbon sequestration by the biosphere takes out of the atmosphere. This means that we have to work incredibly hard on two parallel tracks, simultaneously. On the one hand, cut pollution drastically. And on the other hand, regrow the biosphere. Read more >

In early April I wrote a blog post on the U.S. INDC (“Intended Nationally Determined Contribution”) which was submitted to the UN Framework Convention on Climate Change (UNFCCC). I focused on how it treated the land sector (agriculture and forests). In mid-April this analysis, along with similar consideration of the INDCs of Mexico and the European Union, was written up in a White Paper, and a few days ago we presented the results of this White Paper at a UNFCCC side event in Bonn.
Later in April, U.S. Secretary of Agriculture Tom Vilsack and Senior Presidential Advisor Brian Deese announced the Department of Agriculture’s Building Blocks for Climate Smart Agriculture and Forestry. In this blog post I’ll describe those building blocks, as well as the elements of the President’s Climate Action Plan (released in June 2013) that relate to the land sector.

Thinking about trees often makes you think about your grandchildren. Both start small, can live for many decades, and will grow old in a world very different from ours today. And they’re connected. I expect that my granddaughter Esme, who just turned 1 ½, will probably live in a house made of wood, will write on paper, and perhaps will keep her house warm in the winter, as my wife and I do, with a wood stove. Have we thought about what trees that wood will come from? Read more >
