The Real Climate Hurricane Effect

Nine years ago, a few weeks before the last major hurricane to hit the US, Real Climate said that global warming was going to cause more category 5 hurricanes.

September 11, 2005

“The available scientific evidence indicates that it is likely that global warming will make – and possibly already is making – those hurricanes that form more destructive than they otherwise would have been,” declares an analysis by five climate scientists at

Hurricanes derive their power in part from warm water, and so forecasting models show future hurricanes becoming more severe as sea surface temperatures rise. One summary of 1,200 simulations published in the Journal of Climate last year showed that rising levels of greenhouse gases could triple the number of Category 5 hurricanes. (A link to this study and others appear below this column.)

Moreover, there’s empirical evidence that hurricanes have already become more intense (but not more frequent). Nature magazine this summer reported a new study by Kerry Emanuel, a hurricane guru at M.I.T., indicating that by one measure hurricanes have almost doubled in intensity over the last 30 years.

That reflects natural cycles as well. But Professor Emanuel writes: “The large upswing in the last decade is unprecedented, and probably reflects the effect of global warming.”

A few weeks later Wilma hit, and since then the US has had a record nine years without a major hurricane strike.

    Do you think Gavin gets a bit depressed about how his career choices have worked out? Do they regret their alarmism at all?

    “Better to remain silent and be thought a fool than to speak out and remove all doubt.”

    Real Climate denizens have very selective memories and also great imaginations. They are the equivalent of a children’s theme park based on the movie “Attack of the Killer Tomatoes”, frightening children but making adults laugh. RC strategy is to pretend they never made flawed predictions of doom and then double down on modelled disaster propaganda. RC must be feeling some pressure because Gavin Schmidt tweeted that he wants a moratorium on people frightened by climate change exaggerations not to be called “hysterical”. I suggested to Gavin that might happen right after those suffering from climate hysteria enact a moratorium on the use of “denier”. 😉

    Anxiously awaiting the NYT story speaking about the “large downswing over the last decade”.

    Contrast causes storms. Warming of the poles leads to placid weather.
