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.

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.

President Bush's war on Iraq is viewed broadly in Islamic communities as an attack on Islam, and thus the President has alienated a large part of one fifth of the world's population.

So a truthful assessment of how America is doing in the war on terror as a result of President Bush's war on Iraq is that we have been set back by decades.

In the remaining months, we should focus on achieving more robust international involvement in training of Iraqi soldiers, police officers, judges, teachers, and doctors - all key elements needed to end the sectarian and civil conflict and build Iraq's future.

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.
