I interpreted "20ft" as humorous hyperbole here (a serious prediction wouldn't omit a date, naturally).

The recent studies I've explored predict around 50-130cm by 2100. However, I have seen discussions of ~20ft by 2200 and 26ft by 2300 (https://www.theatlantic.com/science/archive/2019/01/sea-leve...), alongside more alarming figures (https://www.annualreviews.org/doi/10.1146/annurev-environ-10...).

On the other hand, in the 70s all the studies predicted the "coming Ice Age", which not only didn't come out to be, but turned to the opposite (the global warming).

“By the 1970s, scientists were becoming increasingly aware that estimates of global temperatures showed cooling since 1945, as well as the possibility of large scale warming due to emissions of greenhouse gases. In the scientific papers which considered climate trends of the 21st century, less than 10% inclined towards future cooling, while most papers predicted future warming.”

This is false.

Excerpt: "There was no scientific consensus in the 1970s that the Earth was headed into an imminent ice age. Indeed, the possibility of anthropogenic warming dominated the peer-reviewed literature even then."
