You are not wrong that it isn’t a near term concern but I witnessed the lack of progress on global warming in the 1980s and 1990s and do not completely trust experts to make progress by themselves without a larger awareness at the societal level that there is an issue. In many ways the problem isn’t experts but at some point you need politicians involved and they only really react when the voters care. And thus you need the average joe to care so that polticians care and act.

I think that this is the global warming-like issue of the next 3 decades.

The author of this piece basically concluding that there was no issue. She didn’t conclude that it wasn’t a concern for the average joe but that there wasn’t an issue. That is wrong.
