Part 2 of 4: Worldwide Emissions

By Bill Chameides / Published: March 14, 2007

This is the second 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, we described why scientists and policy-makers have identified the melting of the Greenland ice sheet, which would lead to a 20-foot rise in sea level, as the tipping point that must not be crossed. To stay below the tipping point, average global temperatures must not rise more than 3.6oF above pre-industrial temperatures, or 2.3oF above current temperatures.Today we consider how global emissions of greenhouse gases must change over the coming century to stay below that tipping point.

I Met a Bishop… and the Pope!

By Bill Chameides / Published: March 12, 2007

Last Friday, at the invitation of the Catholic Coalition on Climate Change, I spoke at the Climate Change Hearing of the Florida Catholic Conference. The two other speakers in the morning session were Dr. Ricardo Alvarez, who gave a talk on the “Florida Perspective”, and Mr. Walt Grazer, who spoke on the “Theology of Climate Change”. The purpose of this hearing – one of many across the country – was to devise a Catholic response to climate change.

Carbon Offsets Count

By Bill Chameides / Published: March 8, 2007

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.]

Al Gore’s response to charges of being an energy hog was that he buys carbon offsets to neutralize his carbon emissions. This sounded bogus to a lot of people, but in fact it’s not.

According to the Intergovernmental Panel on Climate Change (see IPCC report [PDF] and description of the IPCC), global warming is “unequivocal”, and almost certainly due to human activities. Moreover, the IPCC says, global warming is already doing significant damage – more droughts, wildfires, heat waves, and downpours, and more intense hurricanes. What can we do about it?
