have you seen credible evidence that American efforts to reduce CO2 emissions will reverse that change?
We don't really have a way of knowing for sure to what extent humanity is capable of mitigating the problem. It's possible that it'll all be in vain, or maybe humanity will surprise itself with its own ingenuity as it often does when things get complicated.
It is one thing to track climate patterns, and quite another to suggest we must trade our prosperity for reduced CO2 emissions. It makes far more sense to me to continue on the path we're on - that is, economic growth - and spend our money instead on ameliorating the impact of climate change, if and when such impact should occur. Better to build a prosperous economy with the capacity to ameliorate climate change, than ruin the economy in a vain effort to reverse it.
I think there is a lot that can be done to advance green energy in a healthy way without damaging ourselves. I've said before that subsidizing inferior solar panels so they can "compete" is insanity. We need to be funding research that will give us better panels that can compete with fossil fuels without government subsidies. I think it's only a matter of time until getting energy from direct sunlight outpaces getting it from fossil fuels. Research and development!
AOC is an idealist that doesn't understand the issue and all of the challenges involved in overcoming that issue as well as she should for how much she runs her mouth about it.
