This tweet and the replies to it would not exist if cities took climate change seriously. If we can’t make people who actually *want* to make pro-climate lifestyle changes feel safe doing so, good luck with everyone else.https://twitter.com/Lyndab08/status/1443592372445605894 …

imagine thinking that bike lanes would be what taking climate change seriously meant

It’s not the endpoint of taking climate change seriously, it’s the lowest hanging fruit. If we can’t accommodate people already excited to make a lifestyle change, how can we expect to move anyone who needs real convincing?

if the models are accurate we don't have time for some incremental strategy focusing on something mostly irrelevant

think that’s pretty mistaken, you probably need more efficient short run transport in every case

we need the equivalent of ~100M years of sunlight in energy in the next 100 years because carbon prefers being with oxygen; bicycles are irrelevant

that’s basically totally wrong. the conversion ratio of those 100mm years of sunlight into fossil fuels is incredibly low, and transport is one of the main reasons dense cities are far more efficient than suburbs and car oriented metropolitan areas

sure, a 1-1 ratio is hyperbole, but 10% of this is still on the order of the efficiency of cities being completely irrelevant for solving the acute problem and it's probably distracting from the real problem at the same time

Don’t get me wrong, I support more extreme measures. It’s just that I’m pessimistic about their chances, if they involve people making even bigger sacrifices than “let people feel safe biking”, which is politically popular in dense cities already. What do you propose instead?

i'm all for helping people feel safe biking & more efficient cities, i just think framing this as combatting climate change is counter productive the only way i can see us getting energy on the order needed with today's technology is *a lot* of nuclear fission

solar can do it

it isn't intuitive to me how we could yield some non-trivial factor of 100M years of sunlight from 100 years of sunlight, could you elaborate?

plants start at low percentage points of efficiency in turning energy into embodied carbon, like 3%. they deposit only a tiny fraction of the incident solar energy as carbon about 0.3% maximum in coal fields. this is cut by a factor of about 7-10 in the 1st transformation to coal
