What REALLY Caused Hurricane Katrina?

....according to more and more scientists, it was global warming.

So, unless this world begins to conserve its natural resources and we begin to find energy alternatives to fossil fuels, we should be expecting to experience more Katrinas.

Maybe now those Americans who have been resistant to alternative energy resources and conservation will begin to change their tune?

If not, no one should be surprised or upset when Katrinas happen.

We are being forewarned by scientists.

Our future depends on whether we want to listen or not.

Experts: Brace for More Katrinas
AFP


Sept. 1, 2005 — As rescuers race to reach stranded survivors of Hurricane Katrina, scientists warn that the big storm will not be a unique event. Global warming appears to be pumping up the power of Atlantic hurricanes.

The death toll may reach into the hundreds from Monday's storm, and damages may top $15 billion, figures that put 2005 on track as the worst-ever year for hurricanes, according to experts measuring ocean temperatures and trade winds — the two big factors that breed these storms in the Caribbean and tropical North Atlantic.

Earlier this month, Tropical Storm Risk, a London-based consortium of experts, predicted that the region would see 22 tropical storms during the six-month June-November season, the most ever recorded and more than twice the average annual tally since records began in 1851.

Bush administration officials activated a new national emergency plan and announced they would tap strategic reserves of U.S. oil to ease fears of global shortages.


Seven of these storms would strike the United States, of which three would be hurricanes, it said.

Already, 2004 and 2003 were exceptional years: they marked the highest two-year totals ever recorded for overall hurricane activity in the North Atlantic.

This increase has also coincided with a big rise in Earth's surface temperature in recent years, driven by greenhouse gases that cause the sun's heat to be stored in the sea, land and air rather than radiate back out to space.

But experts are cautious, also noting that hurricane numbers seem to undergo swings, over decades.

About 90 tropical storms — a term that includes hurricanes and their Asian counterparts, typhoons — occur each year.

The global total seems to be stable, although regional tallies vary a lot, and in particular seem to be influenced by the El Nino weather pattern in the Western Pacific.

"(Atlantic) cyclones have been increasing in numbers since 1995, but one can't say with certainty that there is a link to global warming," said Patrick Galois with the French weather service Meteo-France.

"There have been other high-frequency periods for storms, such as in the 1950s and '60s, and it could be that what we are seeing now is simply part of a cycle, with highs and lows."

On the other hand, more and more scientists estimate that global warming, while not necessarily making hurricanes more frequent or likelier to make landfall, is making them more vicious.

Hurricanes derive from clusters of thunderstorms over tropical waters that are warmer than 27.2 degrees C (81 degrees F).

A key factor in ferocity is the temperature differential between the sea surface and the air above the storm. The warmer the sea, the bigger the differential and the bigger the potential to "pump up" the storm.

Just a tiny increase in surface temperature can have an extraordinary effect, said researcher Kerry Emanuel of the Massachusetts Institute of Technology (MIT).

I dont understand complacency when talking abut the environment and it's future.

Sorry, but how do you explain all these hurricanes? Obviously global warming wasn't a factor. I think its just a way to try and support an agenda.

Top 10 Most Intense Hurricanes in U.S. History:

1. Florida Keys 1935
2. Hurricane Camille 1969
3. Hurricane Andrew 1992
4. Florida and Texas 1919
5. Lake Okeechobee 1928
6. Hurricane Donna 1960
7. Galveston, Texas 1900
7. Grand Isle Hurricane 1909
7. Louisiana 1915
7. Hurricane Carla 1961

Yeah, to say that global warming "caused" Katrina is kind of misleading. Is it possible that global warming may have played a factor in making it worse than it needed to be? Maybe. But it's not as if we had passed a few more environment-protection bills this wouldn't have happened. Let's not jump to conclusions. Natural disasters happen. Simple as that.

yes, continue to ignore global warming. it's just a theory, like evolution. there's a agenda in place, you must be right.

it's not the fact that the temperature in the Gulf of Mexico is a degree warmer than it was last year. it's not the fact that these storms are fueled by warm water, so while warming oceans might not create more hurricanes they do much to increase the intensity of the storm and to slow it down so that it creates more damage as it passes over land.

Yes, and you go ahead and continue to ignore my point, Irvine...

No there was a point there, really. Look a little harder..Okay I'll tell you. Global warming was not the cause of the intensity of Katrina. Not unless you can explain away the majority of the 10 most intense hurricanes in history. Your use of sarcasm to discredit the facts is pretty weak.

Who cares about intensity? The point is MORE of them are coming. This is obviously because of global warming. We can't ignor it forever...

Well, it's not a secret that the intense heat of the Gulf of Mexico created Katrina. It was just a Category 1 storm when it hit Florida, and the 90 degree waters of the Gulf of Mexico made the storm explode.

Global warming probably played a role in the strength of Katrina, but something that will make hurricanes more deadly and costly this this is population. Look at the population of costal communities now compared to 25 years ago. There is a huge increase. The more things we build in a potential hurricance path, the more damage there's going to be. If we had more trees and less homes, less people would die and it would be less expensive.

Nothing from before the industrial revolution?

(btw, according to your source, the list you posted were the top-10 deadliest not the top-10 most intense, though the lists are similar)
