Besides, if we don't blow ourselves up, it's a virtual certainty that there will be another completely different geologic event in the next 100 years. And some completely different one on the following 100 years.

Hell, many of the changes from the current event are not even coherent with each other.

IMO, some people are just way too intent on pushing futurology around. (On something similar, people started pushing some grand event that would mark the end of the 20th century at the 80s. Of course, they pushed lots of different ones.)
