You cited specifically an article stating we went over 400ppm as the reason it made sense.
I just don't follow that at all. We're going over unrecoverable limits so don't do anything?
China is certainly causing a lot of pollution building products for the US, but they did sign the treaty and they are also trying to move to renewable energy.
400 ppm CO2 is not an "unrecoverable limit." That's a scare tactic. CO2 has been in the thousands of ppm in the past during periods of glacier growth. Compared to water vapor, it's greenhouse effect is negligible, in addition to water vapor being far more plentiful in the atmosphere than it. This renders any warming effect from rising CO2 several orders of magnitude lower than that of water vapor, meaning it doesn't actually impact temperature or the climate in any measurable way.
No that's not what I am saying though having that happen means there is already a big impact done and dealt with and Obama had a chance to join in this treaty and would be really hard for Trump to back out of but didnt. Yea I know China is and I have been helping promote a new product the Smog Tower that can potentially help out if used efficiently. This deal will harm us more than help. Germany has already went through a deal similar and is did little to nothing to help. And just using solar hurted them with no backup generator, to much at once or to little with selling the rest to nothing in return. We need something that benefits the US equally not have us be the hero in every case.
