over Cenk's optimism.

The evidence is accumulating that the climate scientists had underestimated the gravity of the situation. The fact that the rest of the world (190+) countries would not have agreed is not a valid argument. Many of those 190+ countries, those in the global south especially, did not cause the problem and have the most to lose with the consequences of climate change (draught, famine, flooding, migration, etc., etc.) The US, along with the industrialized world in the global north, bears the responsibility for the historic accumulation of greenhouse gases. The US is the world's largest economy and has the ability to apply diplomatic pressure. Furthermore, the US which is one of the countries contributing the most C02 has the most to contribute to reduction by changing its behavior. It's more than time for the US to show political and moral leadership on this issue. It's also overdue for the elected leaders of this country to show some political will to address this problem. The longer decisions are postponed the fewer decisions will be available.
