Billionaire Sea Level Hype

Guest Post by Willis Eschenbach

Here’s how climate hype works. Bill Gates says:

“All cities will be affected by climate change, but coastal cities will have the worst problems. Hundreds of millions of people could be forced from their homes as sea levels rise and storm surges get worse. By the middle of this century, the cost of climate change to all coastal cities could exceed $1 trillion . . . each year.”

Really? Let’s take a look.

Sea level rise has been at about 2 mm (0.08 inches) per year for a century or so. There MAY have been a slight rise in that in the last couple of decades, although the data is entirely unconvincing. I wrote about this in a post called “Inside The Acceleration Factory“.

But let’s suppose that sea-level rise was to double by 2050. Highly doubtful, of course, but let’s pretend it could happen. That would mean that over the period until 2050, the average rise would be 3 mm (0.12 inches) per year.

It’s 29 years until 2050. So even with this very high estimate, that means that the sea level would only rise by about 9 centimeters (3.4 inches) by 2050.

So I ask you—how is a 3.4 inch (9 cm) rise in sea level going to cost coastal cities a trillion dollars? The smallest waves are that large. And how will that slight rise force “hundreds of millions of people” from their homes?

Obviously, it won’t. That’s just more climate hysteria. In most cities the tidal range is on the order of six feet or so (a couple of meters) from top to bottom … so unless you had an accurate tide gauge, you would never even notice the difference.

But heck, it’s Bill Gates, and he’s rich, so well-meaning fools believe him.
As I’ve mentioned before … math. Don’t leave home without it.

And let me add a second rule—don’t trust billionaires. Guess what? They just might not have your best interests at heart …
