I was just parrotting the interview I listened to but after looking into it it's not false to say that shark incidents are definitely increasing in frequency from using information from https://dlnr.hawaii.gov/sharks/shark-incidents/incident-grap...

Just eyeballing here there was 6 shark atacks from 1980-1985 to about 50 in the last 5 years. Seams like that backs up his claim that there has been a dramatic increase.
