I understand that this is ragebait, but even then, these are not mutually exclusive claims. There being a significant contributor doesn't mean it was the dominant contributor, and you being told things by some people doesn't mean you're choosing your sources well / the same as others.

Mutual exclusivity not applying so much so, that the article you're commenting on downright puts these events into the following hierarchy: groundwater pumping -> climate change -> sea level change. So it'd be a subset of the total effect of it on a theoretical pie chart: literally no conflict in the rhetoric.
