At the moment. But CO2 remains for hundreds of years so it's the cumulative amount that accounts for the current situation. Cumulatively the US has put about the same as China.
Speaking of "colder winter"... seems to be the case in Colorado this year. Not brutally cold, but colder than recent years. Unfortunately, it's been a "dry" cold... lower temperatures but not accompanied by needed snow/moisture. According to the government, the western US has been in an "ever increasing drought condition" since 2001... with Lake Powell and Lake Mead filling only to about 40% of capacity". We out west would like more moisture, or water use restrictions will be in our near future. And before the Lefty "Climate Change" fuckhead zealots can chime in on this thread with their "see, I told you so"... let me remind that the Anasazis were driven out of the southwest 1,000 years ago... likely by prolonged drought... long before there was any thought of "AGW". Most probably it's all been because of "natural earth cycles and the sun"... now, just as then.
You poor dumb bastard, this is exactly why you climate cultists will never be taken seriously. If "they don't", whatever we do will be irrelevant. Further, the United States has been "leading" for 6 fucking decades while the big three polluters, China, Russia and India have done little to nothing. Beyond that there is zero conclusive evidence than man made emissions have any substantive impact on the overall climate that changes, has changed, and will continue to change regardless of what we do, or if human being even exist. Again, first you must explain in detail the why and how all climate shifts happened before industrialization or long before humans ever walked the earth, many of those shifts much more dramatic than we are now experiencing. And when you're done with all that then you can explain how taxing the U.S. into a third world shithole will help anything, anything at all.
Amazing, you still don't know what a greenhouse gas is. Just amazing. Zero evidence? lol Your ignorance is astounding. And you must shit in the streets. No publishing climate scientist on earth denies man made global warming. CO2 is greenhouse gas. Why do you have trouble understanding this simple cause and effect relationship ?
So what? What are we supposed to do? Are we supposed to build a time machine and go back and undo the Industrial Revolution?
So no comment Capt? Do you understand now? Or do I have to keep repeating the obvious common sense science over and over to you?
it's simple CapN.. it's because OrangeManBad, BlackLivesMatter, MeToo and so much more... throw in a HEAVY dose of pathological science and you live in a 'iffin we don't act now, in XX years everything will (insert cataclysmic projection which has NEVER EVER COME TRUE here)... At least we won't have to hear about hashtag AOC by 2031....
