Just because we had a below average hurricane season, that does not discount the mountain of evidence that proves global warming is a man-caused phenomenon.
CO2 is 30% higher than it has been for 650,000 years. Methane is 130% greater. These are two of the main pollutants humans put into the atmosphere in excess, and they are two of the primary greenhouse gases.
Look at the 'hockeystick', which shows a dramatic warming since 1950 after a fairly stable climate for 1000 years. In fact, the 10 hottest years in recorded history have all happened since 1990, with 2005 being the hottest, and 2006 is shaping up to maybe break that record.
(see links below)
How's that for proof of man's fault in this? There is ample proof, any real scientist will tell you that.
There has NEVER been an article doubting man's influence on global warming published in a peer-reviewed journal. A recent study of almost 1000 proved that.
Yes, the earth naturally heats and cools, but the rate and amount we are warming now is unprecedented in the recent geologic past. We are doing this, and we must stop it. This is not some political statement or rhetoric. This is science trying to educate a crass, ignorant public of the damage they are doing. The magnitude of temperature increase ALREADY is about 10x that of the 'little ice age' of the middle ages, and rate and amount are only going up.
Just to be clear, glacial and interglacial cycles are mainly controlled by astronomical fluctuations, but we have a detailed record of the last 7 cycles, and what the climate and CO2 is doing now is way different and extreme. The rate of increase is much higher than in the past AND the value itself is much higher.

I have actually, and most of these so-called environmentalists don't have a response. But the answer is rather easy when the data shows ocean waters are cooler than in the past 10-12 years and thus limit the energy that can be absorbed by these hurricanes.
Many scientists may point out, however, that it does not mean global warming is not occuring, because a large fluctuation in major events such as a hurricane is part of the process of climate change. I don't know for certain, but if there is a large increase in the amount of cold water (ice melt) coming into the ocean belt from the poles this might induce colder tropical surface waters, as well as deep water.
In defense of the alarmists, however, I will cede that in the past 10-15 years we have seen a large spike in the occurrence and power of hurricanes, which runs consistent with many global warming theories. I feel this fact is often ignored by both sides of the spectrum.

There were NO hurricanes this season. Not just "less than predicted". Northern Ice Pack is thinning, glaciers on Greenland are getting thicker. Surface temperatures of the worlds oceans are down a degree or two when the melt should sink to the bottom pushing up warm water, not cooling surface temps. Temperature extremes the past few years still do not match what occurred in the 1930's.
Lots of anomolies here.
Does Man pollute?
Yes we do.
Is it causing damage?
Yes it is.
Should we do something about it?
Yes we should.
Do we need scare tactics with Al Gore trying to recapture his 15 minutes of fame.
No, we don't. It is insulting.
We need good, solid science, with good, viable solutions. Too many fame seekers out there.

Agree with "QFL 24-7".
By the way,the hurricanes season has been decided,in some ways,as starting officially in June and ending at the end of November(Atlantic,north Pacific),but hurricanes can strike in other periods of time too.Depends from the season,El Nino,La Nina,water temperature etc.Difficult to foresee .
I hope it will not happen this year,of course.
I'm not an "enthusiast of global warming",but,this is the evidence.It's happening.
Bye.

The under active hurricane season is from (or so I have heard) the development of La Nina - which is a slight warming of the ocean waters in the Pacific - or off the coast of Africa. I'm not quite sure of the location but it affects all ocean waters which in turn affects our weather. Besides...even if there was not a La Nina at this time no one can truly predict what is going to happen in the future.

Although I believe that the global warming predictions are based more on emotion than science, there is a multidecade periodicity to huricanes. We were in a low occurence period for the last decade not including last year so it is likely that we will be getting more hurricanes in the next few years but this is not related to so called global warming. I think we were probably just lucky this year.

Has anyone asked Global Warming doubters why Artic Glaciers are melting at 4x the normal rate?

One has nothing to so with the other. The polar ice caps are melting. I'm in FL & thinking about buying property in Alabama right now.

normal weather variations still occur, it's the long term trend you should worry about.
that includes higher sea level and some extreme weather events.
