The Senate vote came as climate negotiators are meeting in Bonn to negotiate a new global climate deal. The Guardian newspaper reports the deal is being written in a way that many wealthy countries may actually be able to increase their carbon emissions by up to eight percent above 1990 levels if they take advantage of a series of major loopholes in their pledges. The new UN climate chief Christiana Figueres has openly admitted the pledges made by wealthy countries are not sufficient to meet the two-degree centigrade pledge made in Copenhagen.
