Re "Path cleared for carbon `offsets'" (Business, Sept. 17): Offsets may indeed lesson carbon emissions, but they are only a small step forward. According to the International Panel on Climate Change, odds are at least 95 percent we humans are the principal cause of the global warming which is fueling extreme weather like the recent floods in Colorado and wildfires in California.
With our carbon emissions doing irreparable damage to the civilization our children will inherit, many Americans are eager to shift from fossil fuels to clean energy sources like wind and solar.
A progressively rising carbon tax could spur that shift and be designed to affect us fairly, depending on the amount of dirty energy we use. The tax revenues could be returned to us per capita as an income tax credit. Many industrialized nations already tax carbon. Isn't it time for our Congress to do the same?
