THE ECONOMIST Gives Up On Global Climate Treaties. “This is pretty much where we’ve been for some time: the global approach to reducing CO2 emissions is a dead end, and while the overall science about the climate seems well established, there are some significant fiddly bits that haven’t yet been worked out. There may be more surprises like soot in the works, some good, some bad, but in any case the details, the timing, and the consequences of climate change are less clear than the overall arc, and the case for particular policies is often significantly weaker than the overall case that climate change is under way.”
