I'm not wild about gotcha journalism. But geez I'd love to ask some of the people writing about climate some basic questions. What are total CO2 emissions per year? What percentage is due to the US? To China? To coal? To power generation?

How does the impact of methane compare to CO2? How long does CO2 last in the atmosphere (& how do we know)? Etc. When reading I often have the sneaking suspicion that the person writing has no quantitative understanding at all of climate.

Good intentions + no detailed quantitative understanding is simply a recipe for bad outcomes, in my opinion.

I’ve been restraining myself from writing about this... understanding climate change as a moral crisis is somewhat correct, but risks making it impossible to address the practical crisis.

As a moral crisis it seems somewhat similar to air pollution in the 1960s to me. So many people moralistically saying we need to carpool, drive less etc. Turns out those things had little impact. But catalytic converters, emissions standards etc reduced pollution enormously.

This doesn't mean analogous solutions will help here. But I'm pretty suspicious of the motives of many moralizers.

This, from Naomi Klein, is an example: it comes very close to treating the climate crisis as an opportunity to advance her favourite political causes. I'm pretty suspicious of this style of thinking, no matter what the underlying politics.pic.twitter.com/aS31TayCFw

What's missing in discussions about climate change is the tradeoff we face between mitigating it and economic growth. Here's a little thought experiment highlighting this tradeoff.pic.twitter.com/vBelK85WzJ

Left and right both, for different reasons, want to insist that the cost will be fantastically great. I am super non-expert, but back-of-envelope seems to say ~~2% of global GDP, which we can easily afford.

Exactly. This is a false dilemma. Further, with continued economic growth, it seems quite likely the cost will go _down_ (as a % of gdp). Trying to solve this in the 50s with battery/solar/nuclear costing orders of magnitude more would’t have at all been feasible.

Just to add some numbers: carbon intensity (carbon / GDP) has been dropping 18% a decade in the US (1990-2014, most recent year available).

That’s a great stat. Unfortunately I think far too many people don’t believe in economic growth at all, in which case any number can be explained away.
