We've had TWENTY EIGHT of these meetings and after each one, CO2 emissions have gone up and fossil fuel uses increased.
So, I have ZERO belief that any of these meetings have any value whatsoever. You can cry wolf 28 times and expect to be taken seriously.
It seems that "leaders" everywhere have failed catastrophically because they prefer to destroy the world to maximize their personal wealthy and power even though that means damning their own grandchildren, who will struggle to survive on a ruined planet.
Frankly, to destroy the planet that you and everyone you love lives on is insane.
