Its been interesting to watch the climate debate over the years. The talk has always been about reducing emissions and economic measures. If remediation (and clean energy) had been tackled with the kinds of efforts that won WW2 and put a man on the moon, this problem would be orders of magnitude less now (plus my cellphone charge would last weeks and I'd like that.) Instead "climate change" became all about economic rebalancing and geopolitical issues. We already have technologies that would deal with a lot of the CO2 in the atmosphere but they typically need energy and without clean energy (solar, wind, tidal, nuclear, etc) to power them, they don't do much. Now no one is willing to divert the massive amounts of money needed because that might interfere with the bread & circuses everyone wants.
