Same way that 0.028% CO2 warmed the atmosphere before mankind was ever in the picture. And then there were the ice ages where the world cooled, then the CO2 dropped, then the world cooled some more. If you look carefully at the lag you see it is not just lag but overlap. There is no dispute that warming causes more CO2. But it only causes a little (5-10 ppm per degree C of warming). There is also no scientific dispute that CO2 causes warming. Run any simple line-by-line atmospheric column with and without CO2 and the column is much cooler without it.
The only dispute is whether an increase in CO2 from present levels will cause serious warming. The answer is no. The main reason is that the models are wrong, they presume that the warming is always amplified by increased water vapor. But water vapor is a function of the planetary weather, not temperature.

Psssst- warming happened FIRST- then CO2 rose (and it was much more than 0.028%- CO2 was 1200 ppm, ad there was still cooling and warming during those periods)
[[If you look carefully at the lag you see it is not just lag but overlap]]
I’ve looked at the ice core sample results nd there is no lag- the samples are clear- CO2 rose well after temps rose
[[There is also no scientific dispute that CO2 causes warming.]]
Sure none among the government sponsored LIARS- but there is PLENTY of scientific dispute about CO2 in the amounts present In the atmosphere being capable of causing warming- There is NOT enough of it to capture enough heat, and back radiate it to earth to do ANYTHING regarding global temperatures- Temps rose ALL on their own- then CO2 rose, while temps were still on an upward trend-
[[The only dispute is whether an increase in CO2 from present levels will cause serious warming.]]
Nonsense- there is still the dispute that CO2 in our atmosphere at such small amounts is the cause of climate change
You sound like the LIARS who claim “The issue is settled” (because we say it is so DESPITE the myriad of evidence against it being settled)

Oh really?
from your own type of website, NASA no less:
[[Water Vapor Confirmed as Major Player in Climate Change
Water vapor is known to be Earth’s most abundant greenhouse gas, but the extent of its contribution to global warming has been debated. Using recent NASA satellite data, researchers have estimated more precisely than ever the heat-trapping effect of water in the air, validating the role of the gas as a critical component of climate change.]]

[[I’ll ask one more time- How can 0.0037% of our atmosphere capture enough heat and then back radiate a fraction of that captured heat to cause global climate change?
Same way that 0.028% CO2 warmed the atmosphere before mankind was ever in the picture.]]
You really can’t answer the question, can you? As mentioned several times now, warming happens first, THEN CO2 rises- putting the lie to the claim that CO2 causes warming- by stating ‘the same way 0.028% did way back when’ you are continuing to perpetuate the lie that CO2 causes warming even In the face of the facts which show just the opposite- Can you not see that?
