Take a look at the 25 warmest years that have ever been measured [since 1880]. If you’re 32 years old or more, you’ve been alive for every single one of them. Even if you’re only 20, you’ve been alive for the great majority of them. We, this generation of people, are living on the warmest planet that has ever been measured in the instrumental record.
As the number of rocket launches is expected to increase, the cumulative effect that launching into space has on Earth is expected to be significant and not to be underestimated. A single common Falcon 9 launch emits carbon dioxide into the mesosphere of about 26 km3.[19] A SpaceX Falcon Heavy rocket for instance burns through 400 metric tons of kerosene and emits more carbon dioxide in a few minutes than an average car would in more than two centuries.
