Hurricane Katrina

Mr Gore ascribed Hurricane Katrina to global warming, but there was "insufficient evidence to show that"

 

TRANSCRIPT

 

Now I'm going to show you, recently released, the actual ocean temperature. Of course when the oceans get warmer, that causes stronger storms. We have seen in the last couple of years, a lot of big hurricanes. Hurricanes Jean, Francis and Ivan were among them. In the same year we had that string of big hurricanes; we also set an all time record for tornadoes in the United States. Japan again didn't get as much attention in our news media, but they set an all time record for typhoons. The previous record was seven. Here are all ten of the ones they had in 2004. The science textbooks that have to be re-written because they say it is impossible to have a hurricane in the South Atlantic. It was the same year that the first one that ever hit Brazil. The summer of 2005 is one for the books. The first one was Emily that socked into Yucatan. Then Hurricane Dennis came along and it did a lot of damage, including to the oil industry. This is the largest oil platform in the world after Dennis went through. This one was driven into the bridge at Mobile. And then of course came Katrina. It is worth remembering that when it hit Florida it was a Category 1, but it killed a lot of people and caused billions of dollars worth of damage. And then, what happened? Before it hit New Orleans, it went over warmer water. As the water temperature increases, the wind velocity increases and the moisture content increases. And you'll see Hurricane Katrina form over Florida. And then as it comes into the Gulf over warm water it becomes stronger and stronger and stronger. Look at that Hurricane's eye. And of course the consequences were so horrendous; there are no words to describe it.

 

Sirens, background music, Mayor Ray Nagin. The water is up to my neck. I don't think I'm going to make it.

 

How in god's name could that happen here? There had been warnings that hurricanes would get stronger. There were warnings that this hurricane, days before it hit, would breach the levies and cause the kind of damage that it ultimately did cause. And one question that we, as a people, need to decide is how we react when we hear warnings from the leading scientists in the world.

 

There was another storm in the 1930's of a different kind, a horrible unprecedented storm in continental Europe. Winston Churchill warned the people of England that it was different from anything that had ever happened before, and they had to get ready for it. A lot of people did not want to believe it and he got real impatient with all the dithering. He said this:

"The era of procrastination, of half measures, of soothing, and baffling expedience of delays is coming to its close. In its place we are entering a period of consequences."

 

Making mistakes in generations and centuries past would have consequences that we could overcome. We don't have that luxury anymore. We didn't ask for it, but here it is.

 

 

RULING

 

 

7. Hurricane Katrina.

In scene 12 Hurricane Katrina and the consequent devastation in New Orleans is ascribed to global warming. It is common ground that there is insufficient evidence to show that.

 

William:

 

3. There is insufficient evidence to establish clearly that particular one-off weather events, such as Hurricane Katrina, are attributable to climate change. However, the IPCC concludes that it is likely that there has been an increase in intense tropical cyclone activity in some regions and more likely than not that humans have contributed to this

 

I agree with all that.

 

mt:

 

           Gore seems to me to make no such claim. He is making the obvious analogy to missed warnings, and pointing out the relationship of storm strength to water temperatures, both valid points I think.
