I love graphs that plot China, a nation of 1.4 billion people, against the US, a nation of 0.3 billion people, as though they were equivalent entities. China has a little more than half the emissions per capita of the US, meaning once again and forevermore, USA #1 (at pollution)

I believe in equal opportunities. I absolutely believe in China’s capabilities to collapse our biosphere first. Let’s show those Anglos how it’s done.

guys im upgrading from 16 mpg city to 22 so i think we got this climate trouble on lock.

they might be deeply confused, but every ounce of rocket fuel consumed helps

that's correct. if every human being consumed rocket fuel, the biosphere would be saved

once we become a spacefaring people, the proportion of ffs burned within our atmosphere will decrease, and we will be saved! edit: even more saved than we already are, that is, given how immaculately the proportion of energy from non-ff sources has been increasing. and how splendidly energy and gdp growth are decoupling. edit: and that's not even getting into the good word of second derivatives OIL PANIC has issued a correction as of 20:52 on Nov 27, 2023 |

i should actually read the thread instead of tilting at second hand takes, but how the gently caress are you going to get anything into orbit without fossil fuels. or is the idea that you can use renewables to generate the rocket fuel?

Like, sub-"back of the envelope" math here*, but I think you need something like 30 MJ/kg to put something into low earth orbit, and even then you need periodic boosts to keep it from burning up in the atmosphere. Where are you going to get the energy density for this, if not fossil fuels? * i'm just eyeballing this table https://en.wikipedia.org/wiki/Specific_orbital_energy#Tangential_velocities_at_altitude and comparing the energies of an "at earth's surface" "orbit" with a low earth orbit. i'm a biologist who played a lot of kerbal, please be kind when you tear me to shreds. but do correct me, i'm legitimately curious

Where are you going to get the energy density for this, if not fossil fuels? fossil fuels are not used directly in modern rockets. im sure someone is using kerosene or w/e for a first stage but for performance reasons most use a fuel that is fully synthetic (liquid oxygen/ liquid hydrogen, hydrazine or other fuel types specific to booster types or stages of flight). its probably the easiest application to power with renewable energy since any energy input likely could be replaced with electricity as the energy use is a rounding error compared to anything else we do.

Rocket launches can also deplete ozone, I think this is partially due to the aluminum powder that is burned in place of traditional fossil fuels

sure maybe we can find the energy budget for a space program in a decarbonized economy, but demanding we spend significant resources on space now while any delay in decarbonization causes massive harms requires ignoring that reality
