Thanks for following me all this time. The article is here.
Everyone makes mistakes. I think Gore is trying to be helpful and hopeful. He’s trying to support and celebrate, I believe, recent policy changes to limit emissions from power plants, federal procurement, vehicle MPGs, etc. He also points to several disruptive changes to economies around the world, such as Germany’s aggressive investments in solar and renewables.
Several left-leaning commentators think Gore’s piece was equivalent to the word of God - dozens of high-profile blogs fell over themselves after they read his article (see blatherings at DailyKos, Grist, ecowatch).
From my point of view - which reflects the scientific consensus - Gore is spouting nonsense. The IPCC aggregates climate science from every perspective. Their recent report made it clear that even with maximum policy changes, the earth is on track for up to 4.8c degrees of warming. The policy changes mentioned by Gore do nothing to lower global emissions:
[T]he IPCC assesses a large number of scenarios from different experts. For its third report into greenhouse gas emissions, the IPCC assessed 1200 different pathways, created by different modelling teams around the world….
As a result of its own modelling and the different scenarios it assessed, the IPCC concludes that avoiding the two degrees rise means reducing global emissions by at least two fifths by 2050, and tripling or quadrupling the share of energy the world gets from low-carbon energy by the same date. It probably also means using new, untested technologies to reduce the level of carbon in the atmosphere… Via
I think it’s dangerous to say there is “hope” to reduce emissions based on a few tweaks to the American economy. Every indicator (even conservative economists) shows that emissions are going to rise for decades.
