Science has no idea if climate change is causing more (or fewer) powerful hurricanes.

The Hockey Stick Slayer:

, in partnership with Steve McIntyre, blew the fake MBH98 Hockey Stick graph out of the arena.

Ross now enters the discussion of the Hurricane Harvey, Irma debate.

In the Washington Examiner, Ross writes, Under the title:

Despite Hurricanes Harvey and Irma, science has no idea if climate change is causing more (or fewer) powerful hurricanes

After Hurricane Harvey hit Texas, it didn't take long for climate alarmists to claim they knew all along it would happen. Politico's Eric Holthaus declared "We knew this would happen, decades ago." Naomi Klein stated "these events have long been predicted by climate scientists." Joe Romm at ThinkProgress wrote, "the fact is that Harvey is exactly the kind of off-the-charts hurricane we can expect to see more often because of climate change." 
According to these and other authors, rising greenhouse gas levels are at least partly to blame for the occurrence and severity of Harvey, and probably for Hurricane Irma as well. 
But after-the-fact guesswork is not science. 
Ross goes on to state that even the best meteorologists in the world
weren't able to predict the development and track of Hurricane Harvey until a few days before it hit.
Yep! The idiotic idea that "climate science is settled" has been busted.

A settled theory makes specific predictions that can, in principle, be tested against observed data. A theory that only yields vague, untestable predictions is, at best, a work in progress.  
After Hurricane Katrina hit New Orleans in 2005, some climate modelers predicted such storms would be more frequent in a warmer world, while others predicted the opposite, and still others said there was no connection between warming and hurricanes.

What ensued was an historically unprecedented 12-year absence of major (category 3 or higher) hurricanes making landfall in the United States, until Harvey.
And Ross exposes the commentariat when he closes with:
....when opinion writers tacitly assume all good weather is natural and GHGs only cause bad weather, or claim to be able to predict future storms, but only after they have already occurred, I reserve the right to call their science unsettled.
