I have a layperson’s observation about global warming.  The projections, unless governments and scientists really get to grips with the issue, are alarming, it seems.

Do you think that it’s the case that people like me tend to dismiss such a scenario as millennial (or whatever the 2015 equivalent is) and therefore too terrible to be real – like alien invasion or nuclear holocaust?

Whenever I think like this, I remind myself that 97% of the scientific community concurs that human activity is causing global temperatures to rise and that that augurs worringly for humanity.

  1. I think many people think it’s real but probably not too terrible. When scientists talk about a 2 degree rise in temperature it’s hard to see why that’s such a catastrophic thing.

    • 2˚C doesn’t seem huge, which is why if I’m talking about this I always mention the butterfly effect or (better) the old adage For Want of a Nail, the Kingdom Was Lost.

    • That 2 degree rise is an average over the whole planet, so that represents a lot of energy. If you talk in terms of energy rather than temperature then you can quote James Hansen saying the current rate of warming is “equivalent to exploding 400,000 Hiroshima atomic bombs per day, 365 days per year.”
