The US is only about 15% of the global warming cause. So even if we went to zero the problem would still remain. I can see tweaking the US economy to be more environmentally friendly, but I can't see anything as stupid as the "Green New Deal" as being practical. The pain isn't worth the gain.
First of all remember that there is still no solid evidence that any climate change is a result of anything human...it's just a hunch at best.
And yes.....let's assume that we are impacting the climate....you would be correct according to the Warmists numbers....we account for a very small part of that so called theoretical impact. If we stopped producing all co2 tomorrow even exhaling into co2 capture bags...it wouldn't make a spit's worth of difference to anthropocentric co2 contributions.
