Where is the skeptic community’s model or theory whereby CO2 does not affect the temperature? Where is the evidence of some other natural forcing, like the Milankovich cycles that controlled the ice ages (a fine historical example of a dramatic and regular climate cycle that can be read in the ice core records taken both in Greenland and in the Antarctic)?
The burden of proof lies with those making the claim. There's a difference between saying 'prove C02 raises temps' and 'C02 does not raise temps'... i maybe mistaken in the particular context of this conversion but in the wider scheme i think skeptics generally take the first statement. If the second, then you would be correct to ask for evidence. Skepticism... the lazy man's science but without it you wouldn't be sh*t
Global warming is not an output of computer models; it is a conclusion based on observations of a great many global indicators. By far the most straightforward evidence is the actual surface temperature record. While there are places — in England, for example — that have records going back several centuries, the two major global temperature analyses can only go back around 150 years due to their requirements for both quantity and distribution of temperature recording stations.
These are the two most reputable globally and seasonally averaged temperature trend analyses:
NASA GISS direct surface temperature analysis
CRU direct surface temperature analysis
Both trends are definitely and significantly up. In addition to direct measurements of surface temperature, there are many other measurements and indicators that support the general direction and magnitude of the change the earth is currently undergoing. The following diverse empirical observations lead to the same unequivocal conclusion that the earth is warming:
Glacial melt observations
Sea ice melt
Sea level rise
There is simply no room for doubt: the Earth is undergoing a rapid and large warming trend. And it has been scientifically proven that industrial, man-made carbon emissions are the cause.
This debate shouldn’t be positioned as red pilled vs woke, or denier vs believer. It is simply dumb as sh*t vs educated.
