IMPACTS OF SEA-LEVEL RISE THREATEN CALIFORNIA COAST:

New Report Assesses Risks to 480,000 People

OAKLAND, CALIF. – March 11, 2009 – In an analysis prepared for three California state agencies, the Pacific Institute estimates that 480,000 people; a wide range of critical infrastructure, such as roads, hospitals, schools, and emergency facilities; vast areas of wetlands and other natural ecosystems; and nearly $100 billion in property along the California coast are at increased risk from flooding from a 1.4-meter

sea-level rise – if no adaptation actions are taken. Commissioned by the Ocean Protection Council, the Public Interest Research Program of the California Energy Commission, and the California Department of Transportation, this comprehensive assessment of the impacts of sea-level rise puts California in the lead in trying to understand and adapt to the possible consequences of climate change.

Over the past century, mean sea level has risen nearly eight inches at the Golden Gate in San Francisco according to NOAA oceanographers, and under a medium-to-medium-high greenhouse-gas emissions scenario, mean sea level is projected to rise from 1.0 to 1.4 meters (or 4-5 feet) by the year 2100.

The Pacific Institute report, The Impacts of Sea-Level Rise on the California Coast, concludes that sea-level rise will inevitably change the character of the California coast, and that adaptation strategies must be evaluated, tested, and implemented if the risks identified in the report are to be reduced or avoided.

The four candidates in the 46th Congressional District race debated each other on Oct. 21 at Orange Coast College to an audience of several hundred people. The candidates are Debbie Cook (Democrat), Ernst Gasteiger (Libertarian), Tom Lash (Green Party) and the incumbent, Dana Rohrabacher (Republican). You can hear the candidates’ opening statements and answers to 7 questions. Answers to part of the 7th question and the entire 8th question as well as closing statements are not included because the recorder ran out of disk space. Audio recordings for each question are listed in order below. (more…)

Buying local” has become a mantra of many committed to shrinking their personal climate footprint by limiting the miles their food travels from producer to plate. The increasing globalization of food supplies has served to fan this trend.

However, a new study finds that what you eat has a far greater impact on greenhouse gas (GHG) emissions than where that food was produced. What’s more, saying no to red meat and dairy products even one day a week matters more than buying local all week long.

Number crunchers Christopher Weber and Scott Matthews at Carnegie Mellon University drew on U.S. government statistics from 1997 to expose the entire life-cycle GHG emissions associated with the diet of the average American household.

Emissions fell into one of four categories, starting with upstream supply chain transportation wherein equipment and supplies are supplied to food producers. Then comes the food production phase, followed by final delivery transportation from point of production to retailer. The latter is synonymous with so-called food-miles that are the focus of advocates of buying local. The fourth source of emissions occurs during wholesaling and retailing and includes store heating and air-conditioning and food refrigeration. (more…)

Amid the controversial problem of global warming and its potential impact on human health, there is a rush to fix the blame-either on human activities or natural weather cycles. But the issue is too important for that. We must develop rational strategies to fix the problem rather than fixing the blame.

Over  600 international scientists conclude that human activities that create carbon dioxide, methane, nitrous oxides and chlorofluorocarbons-known as greenhouse gasses-are likely to cause an atypical increase in Earth’s temperature, which, in turn, creates a sequence of ecological changes that are harmful to human health and wellbeing.

A scientific study by the United Nations’ Intergovernmental Panel on Climate Change (IPCC) noted that the Earth’s average surface temperature has increased beyond normal range since1861.

While the exact impact of global warming is uncertain, scientists agree that it will vary according to the severity of the environmental changes it causes and the vulnerability of a certain populations, based on age, nutritional status, health standards, economic development and their use of technology.
