The rockets launched by billionaires Elon Musk and Richard Branson emit black carbon into the stratosphere, where it is 500 times worse for the climate than on Earth. Billionaire Jeff Bezos’ rockets burn liquid hydrogen and oxygen, posing a lesser, but still significant, threat to the climate.
“It would be a real shame for mankind to look back 50 or 100 years from now, when we have thousands of rocket launches a year, and say, ‘If only we’d done something! “.
