I love to think about the fact that the graph for CO2 is like this
And we are literally in uncharted territory for how fucked shit will get and how quickly it will go, these types of carbon jumps usually take hundreds or thousands of years, not decades. At present we are about 1.3°C above the baseline 1850, and this will only continue to accelerate until we hit about 3-4°. We have triggered a feedback loop, which at this point seems to be irreversible. More carbon, more methane are inevitable even if we stop all output of these harmful gases at this very moment.
How was the data shown in this graph aggregated? How do you measure CO2 emission 500 000 years back?
Its ice core data, this nature article describes it if you can access it somehow. “Air bubbles in ancient ice cores” is what NASA says
Maybe spend a few minutes googling this stuff because it’s been answered many times over and it just looks like you’re deliberately trying to poke holes in what is ultimately very well established scientific fact.
To give you a TLDR though it’s ice cores. You look at the air trapped in ice cores, the deeper you drill the further back in time you go because the ice and therefore the air trapped inside is older.
When ice forms, it traps small airpockets in it, so we take samples of ice from the polar circles kilometres deep, date it, crush it to release the air pockets and measure the air contents. Then we can see how different the CO2 amounts were to now.
Source: there’s a fuck ton of different articles that talk about this, and this is the first one I found of Google, search yourself for more.
so far
It certainly was moist
