Reply With Quoteso it was hotter 1310 years ago......hmmmmmmmmm
Another week, another study showing Earth is warming up - with a twist.
This time researchers say there's firmer confirmation for their theory that the past decade has been warmer than anything in the previous 1,300 years. In fact, that might stretch to 1,700 years, they say - depending on whether they rely on the controversial evidence of tree rings showing fast and slow growth as the climate varied centuries ago.
The new study, headed by chief researcher Michael Mann of Penn State University, shows what many previous models have shown. Today's climate is about 0.9 degrees warmer than the long-term average for a period of more than 1,000 years.
The model shows a medieval warm period, not quite as warm as today, from about 700 AD until possibly as late as 1500, followed by a cooler "Little Ice Age" for several centuries. The temperature has warmed up since 1900, with a dip around 1940 to 1970.
But Mann says the real discovery lies in ironing out uncertainties that have plagued climate research.
"It's easy to produce a reconstruction" of past climates, he said in an interview. "But to actually show that it's likely to be meaningful requires a lot more work."
Climate scientists use "proxy data" to show what the world was like centuries ago. These are physical features that still exist today, and which show what the climate was like before thermometers.
Tree rings are a common tool. When a tree grows faster the rings are farther apart, and scientists often infer this means the weather was warm. But this method has carried what scientists call a "curse."
Now, he says, his team has been able to scan through enough other physical features that it doesn't need tree rings alone. In fact, he adds, the new picture confirms the shakier one that came from tree rings.
Evidence now includes coral, which seals in different forms of chemicals depending on whether the weather was rainy enough to dilute salt in the oceans, or dry. In certain areas this points to warmer or cooler conditions.
On land, they use ice cores in glaciers, or sediments in lakes, or stalactites. Each of these can be separated into layers laid down at different time periods.
"We were able to show you can get a reconstruction back more than 1,000 years without tree ring data at all, and you still come to that conclusion" that today's climate is the warmest, he said. "We feel we've removed the asterisk," or the mark of doubt beside earlier models of past climates.

I think the next superhero film Hollywood should do is Captain Planet... maybe then people can get into their thick skulls that we can have an effect on climate change
Though it can't be too controversial.. Wall-E clearly was too overt in showing that it was a film made at the behest of leftist propagandists...... NOT!
so it was hotter 1310 years ago......hmmmmmmmmm

I say let the corporate dickheads burn the Goddamn planet to the ground and to flaming hell with all of us for allowing them to do so. Maybe they'll be able to throw lawyers and pundits at extinction? I'll enjoy watching them shit themselves when they finally push us past the tipping point and start trying to blame chicken-little liberals for the mess. It won't matter by then, and they can buy all the ad time they want to make their case. It'll all be over and done with, and God can go about the business of holding them accountable for the mass extinction of the human race.
I wonder if hell will be hotter than this shithole will be in the end?

As a pragmatist, I see the value in both smelling the roses as I go through life, and in taking a sniff of the milk before dumping it on my cereal in the morning.
A tad more informative then yours?And your contribution to this thread is???
I want to know who was to blame for the global cooling 1310 years ago!
white males that run large corporations. damn those honkies!
and their politician friends. which means more white males.
Budweiser is to beer what McDonalds is to hamburgers
Here's the problem...even if GW is caused by humans, the only way to stop or reverse it is to enforce a massive change in lifestyle. No one (including liberals) wants to do that, so...
"A Liberal is a person who will give away everything they don't own."
Funny, I changed my lifestyle and it was easy, and I save money.
And for the billionth time, yes, we do have an effect on our thin atmosphere, where do you think all our pollutants go anyway?
noone can do it unless its at the end of a rifle. people of all walks of life and political affiliation are comfortable riding around in large vehicles that arent needed (i dont care if they drive them but if you own a truck, its a utility vehicle and if you dont use it as one then you're just a ****ing moron who likes to pay for more gas) going through the drive thru instead of parking their vehicle, not carpooling but instead driving one person per car clogging up traffic slowing it down meaning more gas is being used and more pollutants being put into the air...
in order to truly slow down halt or reverse the processes it would require a major, planet wide change in the way the vast majority of people live, not just america or just china but the entire globe. people are just too damn happy with instant gratification/convenience and too damn complacent to make any kind of changes, even small ones to do anything for the environment, oil prices, anything that impacts a large part of the earth or the human population.
in short people dont give a damn. whether global is real or imagined (i'll leave it up to everyone to decide what to believe in this) there's just no reason for us to be as wasteful as we are. being less wasteful would help this but again...noone wants to make a sacrifice, they just demand more resources.

ThePrankMonkeyI absolutely agree with the necessity for individuals, and nations as well, to assume their own responsibility in monitoring their own ecological habits the best they are able, but seriously, the US attitude concerning this is woefully behind most Western European nations.Noone can do it unless its at the end of a rifle. people of all walks of life and political affiliation are comfortable riding around in large vehicles that arent needed (i dont care if they drive them but if you own a truck, its a utility vehicle and if you dont use it as one then you're just a ****ing moron who likes to pay for more gas) going through the drive thru instead of parking their vehicle, not carpooling but instead driving one person per car clogging up traffic slowing it down meaning more gas is being used and more pollutants being put into the air...

The reason for that has largely been the pervasive "trickle-down" attitude, especially coming from our current government leaders, to simply "consume" and not be asked for any personal sacrifice in fighting "the war on terror".

The Framework

The only thing that the masses pay attention to is having to pay more for something. Gas prices going up has resulted in a big drop in miles driven. 1.4 Billion less miles in April 2008 than 2007. As long as the price stays up there will be a corresponding response by consumers. Even the Chinese and Indians will have to cut back on harmful energy consumption if they find it too exorbitant.
Frankly I look forward to the day carbon energy sources are depleted enough for the world to respond, but I'll be long gone, and the world will be in a situation that will take centuries to reverse....which of course will lead to a huge drop in population, which is a good thing, nature will have the last say.
Who was the head honky in 700AD?!?! Al Gore demands his head!!!
Political correctness is a doctrine fostered by a delusional illogical minority and promoted by a mainstream media which holds forth the proposition that it is entirely possible to pick up a turd by the clean end.

I'm ALWAYS looking for a way to save money. In the winter, I keep my thermostat down to 50 when I'm not there and 66 to 68 when I am. Other than demolition and rebuilding, there probably isn't much I can do beyond that. Anything else would be a major change in lifestyle. I don't really feel like wearing a winter coat in the house.
If the corporations that make all the trinkets that Americans buy were limited in the amount of energy they consume, it might lead to a shortage of trinkets...a change in lifestyle. I don't know many companies that waste energy uncessarily...because it costs them money. Money is their god.
Yes, yes, I know...'there's no room for debate'.
"A Liberal is a person who will give away everything they don't own."
Heretic!! You can't let people make up their own minds. That just isn't right!!
This, I completely agree with.
"A Liberal is a person who will give away everything they don't own."
Wait....Mann? Is he still trying to sell that snake oil? I'll assume it's being attempted the same way as last time, 'getting rid' of the MWP.
Here's a 2000 year global temperature reconstruction, and discussion.

WCR is published and funded by the Western Fuels Association , next time try to find a source that is not in bed and giggling with the fossil fuel industry
Living our values doesn’t make us weaker, it makes us safer and it makes us stronger.
Oh noes! Big oil! I see you're staying true to form, and ruthlessly attacking your straw men.
Are they .. or are they not .. funded by western fuels ?
An honest question .. can you answer one of those ?
Be a big mouse
Living our values doesn’t make us weaker, it makes us safer and it makes us stronger.
It's not The Corporations that are causing global warming, it's The Reptilians. They've been slowly destroying our planet for decades. Their goal is to terraform the planet Earth in order to make it more habitable for themselves. They'll stop at nothing to achieve their diabolical goal!
This is the greatest threat mankind has ever faced.

Can you, or can you not argue the data?
