Idk man, honeslty looks likebthere is a warming trend over the whole graph. Human emissions really didnt kick off until the 1950s. Id say this support the hypothosis that the warm period were in isnt entirely manmade.

So yes, the earth was already warming before co2 concentrations rose? Looks like youre agreeing with me.

And what makes 320 the dividing line in that graph beyond looking nice

Look at the graph again. CO2 (thick black line) is rising from the start of the graph.

320 ppm is used because that was the concentration in 1965 when scientists began reporting on this phenomenon more formally.

That’s also my take. I think man made pollution is harming the climate. But the Earth goes in natural cycles of warming and cooling. It’s really hard to distinguish what amount is human caused or natural with the little data we have.

It's actually not difficult to differentiate, it is just a rather long and boring explanation. If you really are interested in the topic I can only recommend 'Climate Change is a Nightmare' by UpIsNotJump. It is not highly scientific and does a good job at explaining the topic in a rather short, easy to access format. It also debunks statements like 'we are just in a warmer part of the cycle' etc.

Thanks for the video. It was interesting. The carbon and temperature correlation is quite strong. From the same video though, the Earth tilts between 22-24 degrees. 24 being when the earth is warming and has the most CO2 and 22 when it’s the coldest and least CO2. If the Earth is currently at 23.5 degrees, doesn’t that mean the earth is currently in a natural warming cycle as well? Again I’m not arguing that global warming isn’t real. I am saying this is a combination of natural and manmade processes.

It has been a bit since I watched the video, but I think it stated our 23.5 degress were decreasing in the sense that we have reached the 24 some time ago and it is now decreasing again which would mean we would naturally begin cooling again.
