In a summary of the latest scientific research on how unabated global warming is likely to affect California, the governor\u2019s Climate Action Team April 1 rolled out a draft report showing an even bleaker future than previously expected. \u201cThe assessment finds an even stronger set of vulnerabilities to climate change than we thought two years ago,\u201d said Dan Cayan, Scripps Institution of Oceanography climate researcher. \u201cDelay in preparing for climate change is not an option,\u201d said California Energy Commission vice chair James Boyd. Based on the report, he said the Climate Action Team will be developing a plan for how the state can adapt to what appears to be accelerating environmental changes--including reduced water supply. Governor Arnold Schwarzenegger called for action on new water infrastructure in response to the report. He wants new storage reservoirs. The report, which the state has been producing every two years, synthesizes the findings of 37 peer reviewed scientific papers funded by the Energy Commission\u2019s Public Interest Energy Research Program. The papers cover how climate change is affecting California. Some of the studies forecasted events extending 90 years into the future. Boyd said that the chief accomplishment reflected in the latest biennial report is the \u201cdownscaling\u201d of global climate change models \u201cto be applicable to California.\u201d While climate change models project what could happen on the macro scale over wide sweeps of the Earth, they have been comparatively weak on showing what could happen in smaller geographic areas, such as states. The study--open for public comment before it is released in final form this summer--found that: -Electricity demand in the state may rise 55 percent by the end of the century; -Water supplies are expected to become tighter, causing a loss of agricultural production that could cost the state\u2019s economy $3 billion a year by 2050; -The risk of wildfires is likely to increase and cause up to $14 billion a year of damage by the end of the century; and -Grassland habitat is likely to suffer, putting at risk local grass-fed beef ranches. * * * * Diplomats from around the globe gathered March 29 in Bonn for a round of United Nations-sponsored talks intended to lay the groundwork for a new international climate change treaty. The deal is expected to be finalized in Copenhagen in December. Diplomats are negotiating a new treaty to replace the existing worldwide pact on climate change--the Kyoto Protocol--which expires in 2012. The discussions--which run through April 8--are expected to focus on such issues as the scale of emissions reductions, improvements in emissions trading, carbon offsets, and options for handling land-use changes and forestry operations that can change world carbon flux. Delegates to the international treaty negotiation process plan to meet in Bonn again in June. * * * * President Barack Obama announced March 28 that the State Department is set to host a gathering of the world\u2019s biggest economic powers April 27-28 in Washington. Representatives from 17 nations are expected to attend the meeting, which Obama said is supposed to facilitate candid dialogue about how to advance clean energy and reduce greenhouse gases in advance of the United Nation\u2019s final climate change treaty negotiating session in Copenhagen late this year. Leaders of the world\u2019s biggest economies then culminate their preparations for Copenhagen at a meeting that Italian Prime Minister Silvio Berlusconi is hosting in La Maddalena, Italy, in July. * * * * In a move intended to get Manny, Moe, and Jack\u2019s attention, the California Air Resources Board March 26 adopted a rule to require California\u2019s automotive maintenance industry to check the tire pressure of every vehicle it services.The rule takes effect July 1, 2010, under the state\u2019s climate protection law, AB 32. \u201cChecking tire pressure is one of the many simple things that we can all do to reduce our impact on the environment,\u201d said CARB board member Barbara Riordan. Under inflated tires reduce vehicle mileage, which increases greenhouse gas emissions. The Natural Resources Defense Council has been pushing this simple measure for years. By helping to maintain proper tire pressure, the Air Board estimated that each year the measure will eliminate 700,000 metric tons of greenhouse gas emissions and cut fuel consumption by 75 million gallons. It also is expected to extend the average tire\u2019s useful life by 4,700 miles. Some 40,000 automotive service providers are covered, including smog check stations, engine repair facilities, and oil service providers.
