I'd be much more receptive to these "the Paris Agreement wasn't even that strong to begin with" if an alternative was being proposed. But the alternative that the Trump administration is choosing is to attack scientists and deny the problem in the first place.
It’s a deal that’s been hijacked by business interests; just like the Cali proposition written by Uber that’s “for drivers”.
You will never get a hundred countries to voluntarily agree to prioritising climate change over prioritising business interests.
