CO2 did increase a lot. The ratio of CO2 in our atmosphere got up by more than 40% since 2 centuries ago. And that's despite effects which slow down the CO2 increase, like absorption by the ocean.

It hasn't tripled; we've gone from about 280 ppm to about 420 ppm. That graph's y-axis doesn't start at zero. (That isn't to say that 420 ppm isn't really bad.)

  You're right. My tired brain bugged when seeing 30% lower than today.

  That's what's so striking. For most other global warming phenomena, the actual change recorded to date isn't that big. But for CO2, it's huge.
