Global warming does indeed have serious global consequences-- but exotic species like polar bears and faraway island countries like Indonesia aren't the only ones who will feel the pinch.  Right here at home in the San Diego region, climate change threatens us with serious problems.  Factors that make San Diego vulnerable are:

  • Our growing population
  • Urban sprawl
  • 52 miles of precious coastline
  • Our reliance on imported water and energy
  • Vulnerable economic sectors like agriculture and tourism

Check out our page to learn the basics of global warming: 

If nothing is done to curb global warming, the effects on San Diego could be huge:

Home/raindrop.jpgWater Shortages: Warmer climate will decrease the snow pack we rely upon for water. Remaining snow will melt earlier, overwhelming reservoirs,

causing dams to be opened and already limited

water to be lost.


Drought and Desertification: Higher temperatures will increase evaporation while decreased rainfall will dry thi ngs even more. We have already been experiencing a drought since 2000.

Ground-level Ozone: Caused by warmer conditions, ground-level ozone aggravates asthma and other respiratory disorders. It also reduces crop productivity.

Home/flame.jpgWildfires: Drought and heat will contribute to more frequent and intense wildfires.

Heat Waves: Heat waves cause deaths, and power usage during waves can overwhelm the supply, causing blackouts and brownouts.

Sea Level Rise: Rising seas will ruin San Diego’s beaches, and areas like Mission Valley, Coronado and the airport could be underwater.Home/flooding.jpg

The Sierra Club's Cool Cities Campaign is a nationwide effort to curb global warming by getting cities like San Diego, and other cities in the region, to take action now!

The U.S. Mayors Climate Protection Agreement & Sierra Club’s Cool Cities are working to fight global warming!

As of June 14, 2007 532 mayors representing over 66 million Americans have signed onto the U.S. Mayors Climate Protection Agreement, committing to reducing greehouse gas emissions. See our page: U.S._Mayors'_Climate_Protection_Agreement

The “Cool Cities” Campaign was started by Sierra Club in October 2005 to encourage local leaders throughout the USA to move forward with innovative solutions to reduce greenhouse gas (GHG) emissions. Many mayors who might support action to curb global warming do not yet have any strategies in place to meet these targets. The Cool Cities campaign tours the country advocating for local energy solutions that can help cities meet their climate protection commitments. The campaign urges Mayors to join the U.S. Mayors Climate Protection Agreement to reduce GHG emissions and suggests the cities meet their GHG reduction goals by “Greening” their vehicle fleets with hybrid and other cleaner cars, modernizing city buildings with money-saving energy-efficiency technology, and by investing in clean and safe renewable energy.


The biggest single step we can take to curb global warming is making our cars, trucks, and SUVs go farther on a gallon of gas. Many cities are cutting their global warming emissions by purchasing gas-electric hybrid cars and SUVs for their city vehicle fleet. By using less gasoline, hybrid vehicles release a fraction of the greenhouse gases and air pollution emitted by conventional vehicles while saving money at the gas pump. Some cities are also providing incentives such as free parking and lower registration fees to encourage the purchase of hybrids by local residents and businesses.


Energy efficiency means using less energy through better technology to light streets and power buildings and industrial facilities. Reducing energy use is one of the most cost-effective and fastest ways to meet our energy needs. Lowering energy costs enables communities to invest more in schools, job creation, and new infrastructure. Since fossil fuel power plants account for more than one-third of U.S. global warming emissions, saving energy also means less pollution. From high-tech interior and street lighting to energy-efficient building standards and retrofits to efficient combined heat-and-power, cities in every region of the country are modernizing lighting, heating, cooling, and other systems.


Cities across the nation are investing in clean and renewable power like solar and wind energy to lower global warming emissions and create a reliable source of safe, homegrown electricity. Many cities are adopting “renewable energy standards” that require a specific percentage of the electricity sold in a city or utility area to come from renewable sources by a specific target date. Other cities are incorporating renewable energy technologies, such as solar photovoltaic panels, into the design of public buildings. Renewable power and energy efficiency are essential solutions for replacing electricity from dirty, fossil-fuel-burning power plants.
