Academy study reaffirms climate change, but guess what? We have to change consumer habits to save energy

The planet is warming and human activities are the main cause, reaffirms a trilogy of reports, “America’s Climate Choices,” released last week by the National Academy of Sciences.

With business as usual the Earth’s temperature will rise between 2-11.4 degrees F by 2100, the Academy said. And sea levels could rise up to 6.5 feet, considerably higher than previous estimates.

Generally confirming the findings of the UN Intergovernmental Climate Change Panel, which deniers have tried to sully in recent months, the Academy calls for the following steps, which will be very difficult but technically possible:

• Reduce the demand for goods and services needing energy (this is the tough one, requiring changes in consumer behavior).
• Move to low- and zero-carbon energy sources.
• Capture carbon from the atmosphere, with forest and soil, but also with some kind of carbon “scrubber.”
• Improve energy efficiency.

What we need to do now
In the short range, to accomplish these longer-range goals, we must:

• Set an economy-wide price on carbon.
• Invest in and incentivise new technologies.
• Exert U.S. leadership for the rest of the world.
• Have a flexible attitude toward innovation by states, localities and regions.
• Pay attention to greenhouse gases other than carbon dioxide.

The reports were requested in 2008 by Congress, which also asked for recommendations on how to solve the climate problem. The study calls for a closer link between research and decision-making.

Sen. John Kerry (D-Mass.) applauded the study and said it would help passage of his climate bill, the American Power Act. The two dovetail nicely, with the marked exception that there’s not enough in the bill to curb deforestation.
