Have you read the article?
Cory's write-up shouldn't have used the term "climate change insurance," because that suggests that there is a specific policy insuring against climate change problems.
What is happening is that insurance companies are taking the increased risks of bad weather, flooding, etcetera, into account when pricing existing flood insurance, homeowner's policies, and so on.
Analogy: If geologists found a new, giant fault under your town in California, and jacked up earthquake insurance rates for residence, and announced the rate change, you wouldn't accuse them of trying to "make money off suckers."
Well, not unless you didn't believe in earthquakes, or thought that scientists were in cahoots with insurance companies.
