Part 3 of 4: U.S. Emissions Target

This is the third installment of a four-part series to be published each Wednesday on Action Needed to Stop Global Warming.

1. How Warm is Too Warm?
2. Worldwide Emissions Target
3. U.S. Emissions Target
4. Technologies to Get Us There

In Part 1 of this series, I defined the global tipping point as the melting of the Greenland ice sheet, which could cause sea levels to rise 20 feet. In Part 2, I showed by how much global emissions of carbon dioxide (CO2) must drop to avoid this tipping point. They must start to decline around 2020, drop 50 percent by 2050, and drop at least 75 percent by the end of the century.

Meeting these global emissions targets will require a global effort. Even if the U.S. and other developed countries were to cut their emissions to zero, global emissions would likely exceed the targets by mid-century. This is because of the rapid rise in emissions from China and other developing countries.

The Carbon Footprint of… Everything

How do you know that concern about climate change has reached the mainstream? When a product’s carbon footprint is a factor in every buying decision.

And how do you know the carbon footprint of a product? Through eco-labeling – a label disclosing the amount of energy used to produce the product, or the amount of CO2 that producing the product released into the atmosphere. The idea is similar to nutrition labeling – give consumers the knowledge they need to make informed choices.

Auto Industry Changing Gears

Good news for the climate!  The auto industry is calling for cap-and-trade legislation to fight global warming. Car manufacturers have been among the fiercest defenders of business-as-usual, so it’s great to have them on board.

Even better, this shift seems to be a trend. The Chicago Tribune recently reported that big business is starting to push for federal legislation to cap carbon emissions, because the blizzard of individual state laws is driving them crazy.

Fallacies of Movie Critics

ignoratio elenchi n.
A logical fallacy of presenting an argument that may in itself be valid, but has nothing to do with the proposition it purports to prove. Also known as “irrelevant conclusion”. [Lat. ignorance of refutation.]

The recent NY Times piece on the scientists who have criticized the movie An Inconvenient Truth has generated a flurry of discussion. What I saw when I read it was a series of Ignoratio Elenchi fallacies, so the scientists featured in the article win this week’s Ignoratio Elenchi Award.
