Good news about climate change and green energy?

Noah Smith of Noapinion is an interesting economist who makes his arguments based on numbers, numbers, numbers. And graphs. Maybe more than other economists who use numbers and graphs. Today e says the explosive growth of solar and battery power sources means that "our climate debates are out of date." There is lots of climate bad news -- ask Maui, Yukon, British Columbia, Northwest Territories -- but Smith offers a set of numbers that provides reason for some optimism: the plunging cost of solar energy and battery power, and the dramatic growth of new energy sources around the world. Political regimes and private industry of different colors (Texas! California! China!) are piling into this area because MONEY TALKS. Have a look at his arguments and numbers here.
