That sort of happened. The IPCC was founded in 1988 for example. The issue is that it so far has not worked. Going smaller scale to develop some stronger treaties might help though. Especially if it includes some enforcement mechanism and punishments for countries, that do not go along. Like say carbon tairffs for example.
This should have been happening 40 years ago, but now is better than never
