Bag of tricksHalting global warming is the chief environmental challenge of our time.

While heat-trapping carbon dioxide (CO2) is not the only greenhouse gas (GHG), it’s the most abundant and longest-lived in the atmosphere and contributes the most to global warming.  In March, atmospheric CO2 content reached a new high of 400 parts per million, already past the 350 limit many scientists believe is a safe level above which we risk triggering irreversible consequences out of human control.

Second only to China as the largest CO2 emitter, it’s incumbent on the United States to lead the world in addressing global warming.  The Intergovernmental Panel on Climate Change estimates that the window of time to avoid the worst effects is just a few decades.  Yet the United States has not adopted even a nationwide strategy.

Neither producers nor consumers of energy from fossil fuels pay for the environmental and social damages wrought.  These so-called externalized costs are shouldered by the public through illness, droughts, violent storms, coastal community destruction, international conflicts, etc.  Externalizing the costs of fossil fuels keeps their market price low, de-incentivizing society to move to renewable energy sources.

Current strategies to wean off fossil fuels fall into four categories.*  Each attempts to internalize the actual costs of burning fossil fuels through incentives to convert to cleaner energy.

Better Food Choices Get Better Results in Global Warming Battle than Food Miles Reduction
By Sarah S. Mosko, Ph.D.

California Certified Farmers' Markets are "the real thing," places where genuine California farmers sell their fresh-picked crops directly to the public in over 500 communities throughout the state.

“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.
