No I am not. "worst of the worst" was intentionally vague. We are dealing with probabilities. There is a small chance We could hit a tipping point tomorrow and things could spiral out of control. Or a dampening effect could emerge that we did not account for that could delay things for a while. It is hard to overstate just how uncertain things are. Predicting the future is hard. But drastic sea level rise is almost certainly a few decades away, most models predict it won't get really bad till the end of the century. And things like heat stress or hurricane frequency are all likely to increase, but it will be a few decades before they make certain areas uninhabitable.

And for the record, I don't think we are taking this issue seriously enough. Even if the most likely outcome is a slow "boiling the frog" type of scenario, if there is even a 1% chance that a series of tipping points could result in cataclysmic climate catastrophe (which I believe to be the case), then we should absolutely be prioritizing this issue.
