The Paris Accords are proof positive that there is no environmental catastrophe in the works; that climate change isn't a big deal.
All the people, like Joe, who tell us we've got to drastically change our country--by eliminating the oil and gas industries for example-- also support the Paris Accords.
But the Paris Accords allow China to drastically increase its CO2 production. Given that China already produces more CO2 each year than the US and the EU combined that means that under the Paris Accords any cuts by the US won't do anything.
But Joe doesn't care. Hence either Joe is intentionally rearranging deck chairs on the Titanic and he's ok with us all dying or he's lying about there being a climate crisis. He can't think we're facing doom from too much CO2 and still allow China, the largest CO2 producer on the planet, to drastically increase its CO2 production.
On the other hand the US constraining itself by the Paris Accords will make the US less economically competitive, especially since China is producing lots of cheap energy, which is good for China. No wonder China's paid the Biden family tens of millions of dollars.
What's more amazing is that under Trump US CO2 emissions have gone down more than most Paris Accord signatories have. But that's occurred because fracking allowed dirty coal power plants to be replaced with much cleaner natural gas power plants. So when Joe bans fracking he's going to increase US CO2 production.
The only value of the Paris Accords is to make people like Joe and his base feel good about themselves.
Oh one last thing; because "green" energy is much more expensive than fossil fuel energy our energy prices are going to go up. It's no accident that Californians already pay much more for power than people in states which aren't going all in for "green" power--and despite the higher costs Californians still face rolling blackouts like people in third world countries.
But it turns out that poor people spend a much higher fraction of their money on energy than do the middle class or the rich which means that Joe's driving up energy costs by eliminating the oil and gas industries is effectively a huge regressive tax on the poor.
