So says Margaret Wente. How can global warming be stopped if countries that are the largest contributors are not committed to the necessary reductions in their GHG emissions?
Ms. Wente referred to the proposed new US regulations on coal-fire electricity generating plants, such as the large Ohio plant in the attached image. (Source Wikipedia) As she points out, these regulations are subject to review and comment, a process that will last into next year. Expected legal challenges could result in further extensive delay. So there could be little reduction in US GHG emissions for some years, a circumstance that may result in the US missing its Copenhagen targets.
