In the same week large swaths of the US were under extreme heat warnings, Joe Biden’s Justice Department filed its most recent motion to dismiss a landmark climate case by arguing that nothing in the Constitution guarantees the right to a secure climate.
I did not say that the US government does not provide protections beyond what the Constitution says, nor does any of the included things prove that it can not provide protections to freedom of expression, etc, inside of its own borders.
You suggested that to enforce a right to a stable climate would depend on the government’s ability to provide the framework of a stable climate worldwide. While global protections would certainly be ideal, a right to a stable climate could and would likely be construed as an obligation to provide the framework for climate friendly policies within its own borders. Whether the right exists or no (and it probably doesn’t,) its existence does not hinge on it being possible to apply it globally.
Though a technicality, the 1st amendment DOES apply globally. The U.S. government can’t restrict your speech because you happen to be in, say, Canada. They are under no obligation to protect you from Canada’s government or Canada’s laws, but they are obligated to refrain from restricting your speech themselves.
The difference between negative rights (government refrains from interfering and prevents other from interfering) and positive rights (government is required to provide something) is important.
