You can see the change here:

To make it even more scary, it is accelerating. It has increased 75 ppm in 30 years and it was 40 ppm in the first 30 years.
I mean, just the fact that we increased the ppm by ~100, or 1/3rd what it was, in just 60 years is terrifying. Let alone that it’s accelerating. And CO2 isn’t even the worst climate change gas. And there are many positive feedback loops getting exacerbated by the effects…
Good times
Show me a truncated graph and my inner statistician goes:
eugh
I see this sentiment quite often, is it field-specific? Cause in physics and chemistry, starting at 0 is really not required…
In this case, the zero value is really not relevant (since no-one would ever have it anyway). It would just hide the signifcant drift over time. A good scaling here would be based on some clinically relevant interval I guess.
I agree that showing the zero level may be useful here, but… I cannot find a scientific source that shows it differently, so it’s not intentionally misleading at least. The bigger issue IMO is that it doesn’t show enough historic context (ice core data). The original article has it, or nature.org or co2science.org (though it doesn’t show the latest measurements).
This graph is from wikipedia. Feel free to fix it.
Isn’t this the opposite of truncated? They drill down each year’s cycle and show like 80 years of cycles.
The y axis doesn’t start at 0, making it look like the change has been a lot more drastic than it actually was (even though it’s still very bad). I think that’s what they’re referring to
