I do wish articles would link to these studies instead of just talking about them.
I do have a question though. The graph presented starts in 1880 and rises linearly from then, with no correlation to a graph of CO2 levels, which had far more exponential growth between 1880 - 2010s, until recently.
As I understand it, the mini-ice age finished in the 1800s. And started in the 14th century.
So, is this actual evidence? There doesn't seem to be any visible acceleration from what was always happening pre-global warming. And can be blamed on the mini-ice age finishing.
Most worryingly is that page, from scientists, doesn't even address that obvious objection. It briefly mentions sea levels have risen from the 1880s, but doesn't at all address that eyeballing the graph it seems quite obviously linear.
Even more misleading is the graph someone else has linked which starts in the 1990s and doesn't show the rest of the data.
Perhaps you're looking at the graph on a phone screen, which compresses the scale and de-exaggerates the changes?
Look at the slope of 1900 to 1950. Then look at the slope of 1970 to 2020. Are you telling me that's the same slope?
On geological scales we are at or near a high point [2] after the previous ice age

The ice age had a big impact on sea levels, estimates of 100m lower than it is today
What's scary to me is that the carbon content of the very air we breathe has increased by a third since the time when my mother was a child. That's hardly a small thing.
I've been worried about smog, didn't think to track carbon penetration over the last few decades...
Here's a link to global CO2 levels [0]. As I understand it, it's live data from satellites.
You can see it's lower (redder) where forests and plankton are growing, and higher (whiter) elsewhere. You'll also notice that it's pretty much the same everywhere - the range is only 400 - 450 ppm.
