EPA chief on Irma: The time to talk climate change isn't now

Right. And he left out Galveston's hurricane in 1900, which killed as many as 12,000 people.

So what's up with the weather? Making matters worse, two more hurricanes - Jose, a category five-mega storm, and Katia - are expected to follow close on Irma's heels. The agricultural industry, which is very important to our region, can not help but think about what the future holds as the climate changes. Their motto: "I don't care what science says".

"The short version is, climate change makes these very bad storms worse", said Sean Sublette, a meteorologist with Climate Central, a nonprofit group that studies climate change.

Allan said: "While weather explains the formation and track of these tropical beasts, additional heating due to emissions of greenhouse gases from human activities will inevitably make them more deadly".

But - convincing as they may be - these remain "it stands to reason" arguments, not direct measurements of the major tropical storms known variously around the world as hurricanes, cyclones and typhoons.

Answer: While Irma was without question nasty, it wasn't globally record-setting.

A major hurricane is one ranked as a Category 3 or higher, meaning it has a maximum wind speed of at least 111 miles per hour. It made landfall in Texas eight days later. But instead, together they are authoring a new national security doctrine - one that says when faced with a low-probability, high-impact event like North Korea, the USA should spend any amount of money, and if the threat doesn't materialize, well, we'll have a lot of Army surplus and scrap metal. Indeed, Hurricane Harvey went down in storm annals for having more rainfall than any other hurricane in the continental United States. However, this does demonstrate the accuracy of our long-term seasonal hurricane predictions as this year was predicted to be an above-average hurricane year. This was a major variation and seemed to suggest a big swing and a miss by the experts using the existing technology. How much more strain can be put on the National Flood Insurance Program-already $24 billion in the red from Hurricane Katrina? The difference is the coverage of tropical cyclones (via 24/7 news and social media) that brings tropical storm activity much more into public attention. Warm upper ocean water provides the most vital hurricane fodder-energy and water. For example, "wind shear", the variations in wind speed and direction with height, can also cause storms under certain circumstances to weaken or to intensify.

Sublette and Hayhoe said they are all too familiar with the arguments of climate-change deniers. This water vapour then forms clouds, which makes a circular formation, and sucks up the warm air and moisture from the ocean below, adding to their size.

Aside from cuts to scientific research elsewhere, Mr. Trump proposed to end a National Oceanic and Atmospheric Administration program to build better prediction models for tornadoes in the South, and $11 million from a tsunami-warning program for the West Coast.

The impact of global warming on the intensity and scope of hurricanes is an ever-evolving field of study, and the evidence thus far paints a unsafe picture.

Q: What types of weather are we experiencing a spike in?

Katharine Hayhoe, director of the Climate Science Center at Texas Tech University, agreed that now is not the time to lecture hard-hit Florida and Texas residents about hurricane preparedness or how their energy consumption might impact the planet.

However, there have been a lot of major hurricanes recently, which are Category 3, 4 and 5. By changing the environment from the Florida marshlands (e.g., Everglades) to massive urban and suburban landscapes, humans have dramatically increased the damages associated with hurricanes. Given that hurricanes rely on mass bodies of water for their power, it's far from unreasonable to predict that the ever-warming seas will drastically alter the current storm status quo, potentially within millennials' lifetimes.

In addition, the leveling and paving of roads and housing developments doesn't allow the rains to run off as they would in natural marshlands. Really. In Oklahoma, as attorney general, he spent years suing the Environmental Protection Agency.
