Today an article by five co-authors and me was published in the journal Nature Climate Change. It’s on “Ruminants, climate change and climate policy,” and makes the point that political and business leaders concerned about global warming have missed an important part of the problem. This missing piece of the puzzle is the emissions – mostly of methane, a greenhouse gas that is 25 times as powerful as CO2 – that come from ruminant livestock, which include sheep, goats, water buffalo, and most importantly cattle.

Earlier this week we put on our website a page that explains the best estimate of what percentage of global warming pollution comes from deforestation. The percentage — 10 percent — updates the consensus estimate of 15 percent that scientists and organizations, including UCS, released at the Barcelona climate conference in November 2009. It also explains why the decrease only represents progress in reducing deforestation to a limited extent. Read More

This morning, Brazil released its annual data on the rate of deforestation in the Amazon over the past year. But unlike previous years, this year’s figure doesn’t show continued progress. Read More

Today UCS is releasing a new report at the international climate negotiations in Warsaw, entitled “Climate-Friendly Land Use: Paths and Policies toward a Less Wasteful Planet.” The theme of the report is waste and inefficiency — how our current global pattern squanders resources, endangers human health, and damages our climate.

A new paper published earlier this week in the scientific journal PLoSOne calls into question whether we know enough about biochar to use it as an important strategy to mitigate climate change. The article, two of whose co-authors formerly worked here at UCS, did a systematic review of the scientific literature on biochar through 2011, and found 311 relevant papers.
But even with all this research, a key question remains unanswered: How long does biochar persist in the soil? Read More

Over the last two weeks, large numbers of fires have broken out on the Indonesian island of Sumatra, and once again this has led to massive air pollution, carried to neighboring countries such as Singapore and Malaysia. This time, however, people could see not only the choking, dangerous “haze,” but also the locations of the fires, including which ones were on lands used by companies to produce palm, oil, pulpwood, timber, and other commodities. GIS technology and publicly available data, rapidly analyzed by scientists, brought a transparency to the issue that is so sorely lacking in the air over Singapore.
Transferring Forest Land to Communities Helps Reduce Deforestation – and Can Help Government Budgets Too
June 7th, 2013
Who owns the tropical forests? Till recently, the answer has traditionally been “governments,” at least in formal legal terms. But a quiet revolution in forest land tenure has been going on in several countries over the last few decades, resulting in the traditional land claims of forest communities being recognized, not just in law but also in fact. This change, due to struggles by Indigenous Peoples and their allies, has resulted in large-scale changes in tropical forest land tenure, and ironically, could also bring substantial income to tropical governments too.

The week before last I had the opportunity to go to London to participate in a workshop at Chatham House, on an idea that may turn out to be very important in ending tropical deforestation. Over the past several years there has been important progress in reducing forest degradation, based on a simple principle: if it’s against the law to cut down trees in one country, then it should also be illegal to import the cut timber from those trees into other countries. In other words, we should respect and help enforce the laws that protect forests in the countries that we import from.

Has there been any progress at all in reducing global warming pollution? Is anybody doing anything to deal with climate change seriously? Is it all bad news, or are there at least a few rays of hope? As a scientist, I try to deal with these kinds of questions by looking at data rather than just listening to the radio or watching the TV news, which can be very discouraging. And in the last few months, three new datasets have been released that show us what has been happening to Amazon deforestation since the 1990s. Although they have lots of differences among them, they do agree that in the Amazon — the world’s largest expanse of tropical forest — there has indeed been some progress.

In writing about climate change it’s hard to avoid the use of catch phrases and clichéd metaphors, as much we try to stop shooting silver bullets and keep all those pesky canaries out of our coal mines. At times, though, such oft-repeated words are used in paradoxical ways, jarring you into thinking about them a bit more deeply. This happened to me a few days ago when, in response to new Department of Agriculture data on the U.S. livestock industry, a beef producer referred to the impacts of the persistent drought as “a perfect storm.” Read More
