I firmly believe in climate change and global warming.

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.

If you try looking at the actual numbers or sketching rough tangent lines, you'll see that your "eyeballing" is misleading you. The graph is not at all linear -- the slope in recent decades is several times steeper than at the beginning of the time interval, as the accompanying caption says.

Perhaps you're looking at the graph on a phone screen, which compresses the scale and de-exaggerates the changes?

Zoom in and pan around. You'll notice it is not linear.

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?
