Spaceflight has been responsible for 1% of global warming (radiative forcing) in 2009-2019, mainly through dumping black carbon straight into the upper atmosphere. source The number of launches have increased massively since then, and in 2025 they’re several percent.
Each space tourism flight has as much effect on global radiative forcing as 40,000 passenger jet flights. Taylor Swift’s absurd reliance on private jets is a rounding error compared to space tourists. For the median American, their lifetime effect on global warming is less than that of one second of a space tourist being in space.
Thanks for fact checking me!
