Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.
As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades:
How much each change to the atmosphere has warmed the world:
Recommended actions to cut greenhouse gas emissions in the near future:
Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

by focusing on a smaller numerical range, the slope of a linear graph will become steeper. if the graph went from 0 to 420, the entire range of this graph would have to be compressed into about 1/4 the space, so its y range proportional to x will be only 1/4, and since that is what determines the slope, that will be substantially flatter.
I'm not attempting to dismiss or minimise what is shown on the graph, I just think that it needs the added context of what earlier CO2 levels were.
Of course selecting a range that shows the variation makes the variation more visible, but that doesn't mean it's exaggerated. There's nothing about 0 making it the natural point of comparison - some CO2 in the atmosphere is normal. What is important is the shape of the slope - the continued linear growth.
The graph does not give us enough information to substantially interpret what an increase of 100 PPM CO2 in the atmosphere actually means in the greater scheme of things, but that's hardly a fault of the graph - answering that would be a much bigger question. What it does show is that growth has not halted since the 1980s.
I guess it's also worth mentioning that this doesn't mean our efforts have come to naught - for all we know the growth would have been exponential, and we successfully made it merely linear. What's safe to say based on the graph is, however, that what we have been doing is probably not enough.
Also, it's kind of unfair to be equating each of those items because not all of them were actual actions taken to address the problem, and the actions are not equivalent or involve every country. The most substantial actions have only been taken recently, and no one promised that this train could be stopped in a few years.
But it shows us that these big climate summits don't really do anything, apart from generate even more pollution from private jets... They are just a big show to create the illusion of governments giving a shit.
Another interesting factoid, is that the USA does not include it's military emissions in its annual emissions reports, as that would reveal "classified information"..... The military industrial complex must fall, but that's most of the US government lol.
It's not just the numerical range, it's also the time scale. What I'm getting from the graph is that they wanted to convey instances of humanity saying "this is a problem and we should do something." Meanwhile the problem just compounded. Expanding the time and count scales would show the start of the rapid upswing that came with the Industrial Revolution, for instance. This is useful for context (and has been done many times over), but leaves no room to pick out the events noted.
