I'm not doubting the science, just curious as to what other methods they used to come up with their conclusions besides the obvious measuring of weather patterns.

Humans have been tracking weather patterns for what, a few hundred years at best? The Earth has been around for what, 4.5 billion years? 5% of 4.5 billion is 225 million years. So we have to have tracked the weather pattern for 225 million years and noticed an uptick in temperature before we can say its a trend. How do we know the climate change we are currently experiencing isn't just some sort of random blip?

I think you're getting at a 5% difference being used to determine whether something is statistically significant? 5% is the probability that a difference is real vs. due to random variation, and has nothing to do with the time period. It's based on statistical tests which account for the magnitude of the observed change and the amount of variability in the measurements. Also, the number 5% is fairly arbitrary and not universal - it's about balancing the probabilities of false positives vs. false negatives. Based on the amount of variability in temperature, I think most climate experts say you usually need around 30 years (off the top of my head) to demonstrate a statistically significant trend, but even that would depend on the magnitude of the trend.

Remember how Flash Walken warned all of you about Tinordi baiting you guys into a Global Warming debate?
Well done, morons.

Talking about this disaster without talking about global warming is a bit vapid no?

Sure, except that's not really what this thread was about. You just sort of randomly plucked it in for your own amusement. The thread was about what was going on at the moment, reports and new and discussions about that. An overall Global Warming debate could use it's own thread and probably has several other threads that you could have placed it in. Without derailing this one.

I agree with MMF...Less debating, more stories and pictures.

Well I would very much argue that talking about global warming in the context of this storm isn't derailment. At least, from what I have been saying up until Yen's reply.

Some crazy pics that show the power of a cat1 storm, bad luck resulted actually from a full moon high tide and it combining with an upper low moving down from "us truly" (perfect storm)
Brigantine, New Jersey
Tuckerton, New Jersey
A Virgin Mary statue stands in the Breezy Point neighborhood of Queens, New York, on Tuesday after a fire fed by high winds destroyed at least 80 homes.
A resident walks down a street covered in beach sand due to flooding from Hurricane Sandy in Long Beach, New York on Tuesday.

I agree this one shouldn't be blamed just on global warming but I thought I should respond to your post that lacks much if any facts.
1) Because a large storm didn't make landfall in the USA doesn't mean it didn't happen.
2) Since the recording of "named storms" began in 1851 the average has been 11.7 per year, Sandy was the 19th named storm this year in the Atlantic and 6 hit land somewhere that caused deaths.
3) Since 1995 the average is roughly 35% higher than the previous 140+ years. And this average is about the same for Pacific named storms which kill far more
At this point does it matter if humans are contributing to the oceans/planet warming up? we couldn't cool it in 300 years even if we turned everything off. Question should be... can we slow it down a little or at least adapt to it with education and save peoples lives?
