The hypothesis is that global warming will add more water vapor into the atmosphere and thus more energy into the atmosphere. More energy = more extreme.

The hypothesis, however, is only a hypothesis. Last hurricane season was one of the mildest in decades. The deadliest hurricanes to hit the US were in 1928 and 1900. Katrina only ranked 3rd because of the levies being in disrepair. The fourth and fifth most deadly hurricanes occurred, BOTH occurred in 1893.

In 7 years, the US has 3 of its top 5 most deadly hurricanes and this had absolutely nothing to do with CO2.

So before falling for the hypothesis with talks of Katrina, ask for a statistical analysis that show that the frequency of whatever disaster has increased in a statistically significant fashion.

Stubby,

I do not watch any Youtube videos. I find they are mostly crap. BUT, I make no distinction between Youtube videos that "warmers" or "skeptics" use as a reference. I don't view either. Think of this, what you will.

Graphicc,

Thanks for letting me know. I expect an ad hominem attack given his statement was basically that all who disagree with him are close-minded.

And speaking of the last Youtube video I watch by Bill Nye, where he so botched an experiment and so misrepresented the theory of global warming as to given me a headache,..., I think I am going to put on a lab coat. Then eveything I say must be believed.

Graphicc,

What are you doing? You are linking to a study that shows warming leads to less storm activity? Soon we are going to hear how there will be no storms and thus no rain and thus droughts everywhere and the end of life as we know it.

It all has to do with energy.

Basically, energy and/or heat drive most of the weather on this planet. Heat causes water to evaporate from the ocean and other bodies of water, and then cooler high-altitude air causes the water to re-condense and fall as rain or snow. Differences in temperature drive air circulation patterns (water circulation is also driven by differences in salinity). Warm and cold air currents meeting in the right way is how you get things like tornadoes and hurricanes. And so on.

So, changing the amount and/or distribution of heat on the planet, which global warming does, will change weather patterns. Some of those changes may not be more "extreme", but they will tend to be *unexpected*. Which can, effectively, make them more extreme for those living in the area. If several feet of snow falls in a place that regularly gets 15 feet of snow a year, they'll be prepared. There will be snow plows, people will have food reserves in case they get snowed in, roofs will be built with snow in mind, and so on. But if a foot of snow falls in a place that usually gets an inch or less of snow a year, no one will be prepared and things will be damaged and people will get hurt.

The same is the case for things like drought and flooding. An amount of annual rain that would cause severe flooding here in Phoenix would be a severe drought somewhere like Seattle.

We're not sure what effect warming has had or will have on somewhat more complicated weather systems, like hurricanes. Warming may lead to more frequent hurricanes, less frequent but more intense hurricanes, or some other result entirely. The same goes for tornadoes and other "extreme" weather events.

I don't think it does. The weather was more extreme in the (cooler) Little Ice Age than it is now.

@Stubby: I managed to watch the first 15 minutes. The main thrust of the argument seems to be that global warming sceptics are related to evolution deniers and the pro-smoking lobby. This is a form of "ad hominem" argument that was known to be fallacious by Aristotle many years ago. (These people are silly, these people assocate with them so they must be silly as well.) So, good try but no cigar!

EDIT: Have a link to many papers that suggest that cooler means more extreme weather. http://hockeyschtick.blogspot.co.uk/sear...

So, in practice, more energy means less extreme weather.

I think it is the sun, The solar magnetic AP index (which is very low at this time) effects earths magnetic field and causes disruption of the atmosphere especially in the polar regions, which is why the jet streams meander and come south, causing all kinds of anomaly's

It doesn't.

Quote by Will Happer, Princeton University physicist, former Director of Energy Research at the Department of Energy: “I had the privilege of being fired by Al Gore, since I refused to go along with his alarmism....I have spent a long research career studying physics that is closely related to the greenhouse effect....Fears about man-made global warming are unwarranted and are not based on good science. The earth's climate is changing now, as it always has. There is no evidence that the changes differ in any qualitative way from those of the past.”

The press will just lead you to believe that this is unusual.

Quote by Charles Alexander, Time Magazine science editor: “I would freely admit that on [global warming] we have crossed the boundary from news reporting to advocacy.”

According to the IPCC, there has been no increase in extreme weather activities. They assign low probabilities to possibilities of future extreme weather and tipping points.

No and if anybody says it does has no evidence .

Usually its liberal newscasters says it does .

Besides the planet stopped warming in 1998 .

"The idea that any of the weather we are seeing is in any significant way due to humanity’s greenhouse gas emissions verges on irrationality." http://www.drroyspencer.com/2014/02/how-...

Warming is less stable

More temp, more evaporation, more rain and snow

Deniers have closed minds and will not watch this video
