More On Global Warming

German Chancellor Angela Merkel's plan to reduce emissions by 50 percent by the year 2050 has been approved at the G8 summit in Rostock, Germany. But, in deference to President Bush's objections, it holds no weight of treaty.

While the jury is still out with regards to global warming, striving to cut emissions, if for no other reason than to reduce health risks, is a good thing.

There is still room for optimism. The president says he wants to convene a summit of major polluting nations with a goal of cutting emissions by 2009. Let's hope that effort results in more substance than form.
