cumulative CO2 emissions: It is the level of the concentration of greenhouse gases in the atmosphere, not the current level of emissions, which determines the extent of the warming effect from their presence in the atmosphere. In other words it is the cumulative effect of past emissions from all sources that matters – the stock of CO2 rather than the flow - and in that regard the U.S. is determined as the single nation most significantly responsible for climate change impacts today.
Lol, I love how you need to go back to 1850! 😂 When China wasn’t even industrialized. Btw, how do volcanic eruptions stack up to the chart you posted? Any idea?
Regardless, what’s your position going to be when China over takes them? Why are you ok with China deferring reductions for another 8 years? Isn’t climate change an urgent issue?
