When climate negotiators meet in Bangkok this week for the latest session of the UN Framework Convention on Climate Change (UNFCCC), they will (hopefully) begin substantive discussions under new terms better reflecting how much the world has changed since the Convention’s adoption in 1992.
Of particular relevance is the dramatic shift in the distribution of global carbon dioxide (CO2) emissions over the past two decades, as highlighted in the Netherlands Environmental Assessment Agency’s 2012 Trends in global CO2 emissions. A telling statistic: In 1990, industrialized countries that negotiated targets under the Kyoto Protocol (including the U.S.) accounted for 68 percent of global CO2 emissions; in 2011, the authors estimate, this share was 41 percent. Developing countries now account for well over half of annual global emissions – with China and India generating a full third.
As early as this week, the federal government will announce what is likely the largest move ever to save oil. If last year’s proposal becomes final, as expected, the fuel economy of a typical new car will go up by more than 70 percent by 2025. The standards will improve how far cars and trucks travel on a gallon of gas even more than the original corporate average fuel economy (CAFE) standards, enacted by Congress in 1975.
The new passenger vehicle standards for fuel economy and greenhouse gas emissions are also the single largest move by the federal government to address climate change. Three critical factors made this possible: consumer commitment, technological progress, and smart public policy.
I recently responded to a question on the National Journal blog, "Should Congress extend the production tax credit for wind energy or let it expire at year's end?"
Despite the very different views of the majority and minority parties in the Senate, there was in fact a fair degree of agreement among the witnesses at today’s hearing on climate science and local adaptation.
During the climate science portion of the Senate Environment and Public Works Committee hearing, both the majority and minority witnesses agreed that the Earth has warmed over the past 120 years. With the recent publication of the Berkeley Earth Surface Temperature project by former skeptic Richard Muller, there are now four (NOAA, NASA and Hadley are the others) major global temperature records that are in agreement that the Earth has warmed 1.5 degrees Fahrenheit over the past 50 years.
Today’s Senate hearing isn’t just about the science of climate change. It’s also about the actions that need to be taken now to adapt to the reality of a changing climate. Businesses and governments each have a critical role to play in building resilient communities and economies.
Business-as-usual is already being interrupted by extreme heat, historic drought, record-setting wildfires, and flooding. Events from water shortages to floods are disrupting the supply chains for such companies as Honda, Toyota, Kraft, Nestle and MillerCoors. By the end of 2011, the United States had recorded more billion-dollar disasters than it did during all of the 1980s, totaling about $55 billion in losses.
