Regardless of whether you think the commitment is credible, a position on climate change adopted by the G7 bears consideration:
For one thing, it’s questionable when politicians set goals so far off in the future. For another, we need to phase out fossil fuels much more rapidly if we’re to avoid catastrophic climate change. Nonetheless, there’s one important message here: fossil fuels have no long-term future, and that is increasingly being recognized by the world’s most powerful governments.
Hopefully, this will help people come to grips with the implications of the carbon bubble, and make people think more critically about the appropriateness of building long-lived new fossil fuel infrastructure like pipelines.
