Anyway, this hurricane season has been rediculous, it is already at K for Christ's sake.  Global warming is not the only reason, though. a very active year was already predicted, and we are supposed to be entering an active phase of a multi-decadal cycle. But add global warming to the mix and it doesn't look good.  |
Well, I don't consider myself an idiot - I tend to listen to those that know something about their works. In current case meterologists, and when they claim that their statistics says that there isn't more hurricanes than previously, well, I belive what they say. Of course they could be lying, but with both critical press and greenpeace hunting them, I seriously doubt that such lies will survive for long.

The Medieval Warm Period and Little Ice Age mainly affected Europe, Eastern North America, and the north Atlantic. And the Greenlard argument is moot, it was BARELY habitable when they settled it, it didn't take much cooling to drive the settlement into oblivion. It is already warmer as a global average than the MWP, and it is getting pretty close to Altithermal (warmest part of the current interglacial 8000 years ago) levels. |
As far as I know, it's highly discussed wether the climate that allowed settlements in greenland was local or not.
You say that it was a boarderline case if the greenland settlements could survive, and maybe it was, but you forget one thing. Current climate in that area demands a very serious change to allow a similiar settlement. Ciurrently it is impossible to do what those vikings did.
I don't doubt for a minute that climate are changing, I just doubt that feeble human activities can compete with nature - especially in those areas where we still haven't a clue about what is going on.

The warmth of the MWP and the cold of the little ice age was centered on the North Atlantic, the impact on the rest of the world was much less, indeed, many scientists don't think they were global at all.
The geological record shows that over millions of years climate goes in step with changes in CO2. at the end of the Eocene epoch there was a massive cooling of the climate that ussered in our modern Ice-House world. the change was concurrent with CO2 being absorbed by the weathering of the newly formed Himalayas. No intelligent person can deny that we are the cause of the rise of CO2 levels today, it started at the same time as the industrial revolution, and if CO2 level changes were the cause of climate shifts in the past, using the principle of Uniformitarianism, they will be the cause now.

Uhm, no, as far as I know, it was not a local "heatwave" that allowed settlements in greenland. I know that i'ts a loved claim of the hockey stick theory that it was local, but it isn't. The rest of the world had similiar rises in that period.
I don't deny that human activity is the cause of growth in CO2, I just question if that is the cause of climate variances. Latest theories even claim that it's the start of growing rice that has prevented northern europe from being covered in ice. I'm quite sceptic to this theory.

How many causualties were there in the Galveston hurricane in the early 1900s?
Isn't that the record for hurricane deaths? With better construction, prediction, evacuation, etc, New Orleans will fare far better than that. But it's still not pretty to think about when it will make landfall...

SOME meterologists. 
Nearly all climatologists say the current bout of climate change is caused by humans. So you are calling all those 1500+ highly respected scientists on the Intergovermental Panel on Climate Change (IPCC) fanatics? Tools of the eco-nut political agenda? 
Scientists have been concerned about global warming as far back as the late 50's, long before the eco-nuts jumped on it for thier own political agenda in the 80's.
A war-like situation.
