Wishful Thinking Is Not Sound Public Policy.

My Suggestion Is That We Should First Work To Ensure The Third World Has Clean Drinking Water And Sanitation.

The Total Efforts Of The Last 20 Years Of Climate Policy Has Likely Reduced Global Emissions By Less Than 1 Percent, Or About 250 Million Metric Tons Of Carbon Dioxide Per Year.

Money Spent On Carbon Cuts Is Money We Can't Use For Effective Investments In Food Aid, Micronutrients, Hiv/aids Prevention, Health And Education Infrastructure, And Clean Water And Sanitation.

So It's Mainly A Question Of Helping The Third World Overcome The Effects Of Global Warming.

The Second Thing Is, If You Want To Do Something About Global Warming, You Have To Think Much More Long-term. There Is Something Wrong With Saying We Should Start Using Renewables Now, While They Are Still Incredibly Expensive.
