The U.S. National Climate Assessment: A Detailed Evaluation of the Scientific Evidence on Climate Change

We have heard a lot in the past few weeks about the latest international assessment of climate change impacts as new reports have been finalized by the Intergovernmental Panel on Climate Change. Of course climate change is a global phenomenon occurring over decades and, for many, it is hard to relate to new information about global changes. But help is on the way! The third U.S. National Climate Assessment is scheduled for release on May 6. Read More

Cows Are the Real Hogs: The IPCC and the Demand Side of Agriculture

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.

What Are We Doing with our Planet’s Land? A Report from Berlin

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.

The New 400ppm World: CO2 Measurements at Mauna Loa Continue to Climb

The level of carbon dioxide in the atmosphere reached 400 parts per million for the first time in human history at Mauna Loa Observatory in Hawaii in May last year. That same level has been reached again in the last few days. This year we’ve hit the target in March, two months earlier, and it will stay above 400ppm for longer. At that rate, it will only be a handful of years until we are living in an atmosphere permanently above 400 ppm. While 400 ppm is a somewhat arbitrary marker, humans did not exist the last time atmospheric CO2 was at that level. Read More

Four Climate Change Facts To Keep the Senate Up All Night

Tonight more than two dozen Members of Congress from the Senate Climate Action Task Force will be holding the Senate floor to discuss global warming. A number of them are expected to participate throughout the night. Here are some startling climate facts that keep me up at night: Read More

Many World Heritage Sites are Predicted to Fall Victim to Climate Change

Hot on the heels of news that recent extreme rainfall has caused walls to collapse at ancient Pompeii in Italy, comes a new study showing that hundreds of other iconic places listed by UNESCO as World Heritage Sites are threatened by sea level rise. Philadelphia’s Independence Hall, Mont Saint Michel in France, Leptis Magna in Libya and the Tower of London are all identified as vulnerable to rising sea levels. Read More

Climate Change and Nuclear Power

The Union of Concerned Scientists (UCS) recently received by email an open letter by four nuclear scientists and engineers—Andrew C. Kadak, Richard A. Meserve, Neil E. Todreas, and Richard Wilson—titled “Nuclear Power’s Role in Responding to Climate Change.” Below we look at some of their arguments. Read More

Can State and Local Action Kick-Start Global Cooperation on Climate?

Poland’s political leaders need to meet West Virginia’s State Senate President Jeff Kessler. At a recent forum on increasing economic diversity in the state, Kessler said, “Coal has been king in West Virginia for 100 years, but it hasn’t taken very good care of its subjects.” While Kessler was referring to the poverty many of the state’s largest coal producing counties have experienced, people in Poland are facing serious health consequences because of coal. One study from Bankwatch reports that living and breathing in Krakow for a year, a resident inhales as much benzopyrene, a highly carcinogenic pollutant, as he or she would from smoking 2,500 cigarettes.

Beef, the Climate, and Human Health: Changing our Wasteful Food and Land Use System

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.

Climate Science, Nuclear Power, and a Renewable Energy Future

Contrary to the public assertions made this week by some of our climate scientist friends, nuclear power is likely to have a limited near-term role in avoiding the worst impacts of climate change. Renewable energy technologies are cheaper, less risky, and ready for deployment today. A look at where things stand with both nuclear and renewables bears all that out. Read More
