increases in vehicular travel under the proposed plan deserve, and CEQA requires, serious and thorough environmental analysis.
The DPEIR Should Discuss The Plan’s Impact On Climate Change.
Despite the Plan’s heavy reliance on vehicular travel and improvements to freeways, roads and streets, and the acknowledged increase in vehicle travel that the Plan will encourage, the DPEIR never analyzes one of the most important environmental impacts of vehicle emissions--greenhouse gases and resulting climate change
Climate change results from the accumulation in the atmosphere of “greenhouse gases” produced by the burning of fossil fuels for energy. Because greenhouse gases (primarily, carbon dioxide(“CO2”), methane and nitrous oxide) persist and mix in the atmosphere, emissions anywhere in the world impact the climate everywhere. The impacts on climate change from greenhouse gas emissions have been extensively studied and documented. (See Oreskes, Naomi, The Scientific Consensus on Climate Change, 306 Science 1686 (Dec. 3, 2004) [review of 928 peer reviewed scientific papers concerning climate change published between 1993 and 2003, noting the scientific consensus on the reality of anthropogenic climate change]; J. Hansen, et al., Earth’s Energy Imbalance: Confirmation and Implications, Sciencexpress (April 28, 2004) (available at http://pubs.giss.nasa.gov/abstracts/2005/HansenNazarenkoR.html ) [NASA and Department of Energy scientists state that emission of CO2 and other heat-trapping gases have warmed the oceans and are leading to energy imbalance that is causing, and will continue to cause, significant warming, increasing the urgency of reducing CO2 emissions].)
In California, the state government has acknowledged the true environmental impacts of greenhouse gas emissions on climate change. Governor Schwarzenegger, in his Executive Order S-3-05 issued on June 1, 2005, recognized the significance of the impacts of climate change on the State of California, noting that “California is particularly vulnerable to the impacts of climate change.” The Order goes on to itemize a litany of the direct impacts that climate change and the increased temperatures resulting from the increased presence of greenhouse gases in the atmosphere, will have on the state:
“[I]ncreased temperatures threaten to greatly reduce the Sierra snowpack, one of the State’s primary sources of water;”
“[I]ncreased temperatures also threaten to further exacerbate California’s air quality problems and adversely impact human health by increasing heat stress and related deaths;”
“[R]ising sea levels threaten California’s 1,100 miles of valuable coastal
