We all know we have a problem, a broad problem. Ninety-eight percent of the fuel that is used by our vehicles, our autos and trucks for personal and commercial purposes, for highway and air travel operates on oil. The world has the same problem.

As a scientist, my attention became totally focused on global warming some 15 years ago by the elegant and powerful measurements of carbon dioxide trapped in ice cores taken as much as 2 miles deep from the great East Antarctica ice sheet.

Since 1850, burning of fossil fuels, coal, oil and natural gas has increased 100 times to produce energy as the world has industrialized to serve the world's more than 6 billion and growing population.

The scientists who do climate research understand that much of the ever increasing concentration of CO2 in the atmosphere since 1850 must be attributed to burning those fossil fuels to produce the energy that drives industrialization.

We all know we have a problem, a broad problem. Ninety-eight percent of the fuel that is used by our vehicles, our autos and trucks for personal and commercial purposes, for highway and air travel operates on oil. The world has the same problem.

America has lost the moral high ground with the rest of the world, and we have fewer allies as a result. President Bush and his administration have undermined the war on terror by using tactics outlawed by international treaty and condemned by even our closest friends.

The conduct of President Bush's war of choice has been plagued with incompetent civilian leadership decisions that have cost many lives and rendered the war on and occupation of Iraq a strategic policy disaster for the United States.
