so far
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 some random sites say.
It certainly was moist
