The California Global Warming Solutions Act of 2006:The 2009 United States Global Warming Act?

Greenhouse gas (GHG) emissions trap solar heat in the atmosphere, increasing global temperature by an estimated 1.4 degrees. Increases in global GHG emissions, resulting largely from increasing global energy use, have led to more heat being trapped in the atmosphere, leading to global warming. Major impacts of global warming include rising sea levels, higher temperatures and increased global migration of disease-carrying insects. While there is continuing scientific discussion regarding how quickly the earth’s atmosphere will warm and when the adverse global warming impacts will occur, most scientists believe that GHG emissions must be reduced 50-80 percent in the next 50 years to minimize adverse impacts. Carbon dioxide (CO2) accounts for over 80 percent of GHG emissions, and is the principal focus of GHG reduction programs. The United States, with five percent of the world’s population, generates 25 percent of global GHG emissions. The U.S. has recently been overtaken by China as the largest generator of GHGs. Electricity (generated from coal-fired power plants), is second only to deforestation as a global source of GHG emissions. One way to reduce global warming is to move to cleaner sources of electricity, such as solar energy and wind energy. Another is to reduce energy use. Both are part of the California global warming program, which is likely to serve as a model for U.S. global warming legislation, which will be debated in the next year or two
