'Proof' humans cause global warming
Courier Mail ^ | 10/20/09 | From correspondents in Washington

Posted on 10/26/2009 1:08:59 PM PDT by NormsRevenge

SEDIMENT cores from a small Arctic lake in Canada stretching back 200,000 years show unprecedented gains in global warming since 1950, indicating human activity is the likely cause.

"The past few decades have been unique in the past 200,000 years in terms of the changes we see in the biology and chemistry recorded in the cores,'' University of Colorado glaciologist Yarrow Axford said.

"We see clear evidence for warming in one of the most remote places on Earth at a time when the Arctic should be cooling because of natural processes."

Mr Axford is the chief author of the study published in the Proceedings of the National Academy of Sciences.

For thousands of years, environmental changes in a remote lake on Canada's Baffin Island closely matched natural, cyclical climate changes such as those caused by the Earth's periodic wobble as it swings around the sun, the researchers said.

However, lake sediment cores dating from 1950 show that expected climate cooling was overridden by human activity like greenhouse gas emissions.

Researchers were able to reconstruct the local climate over the past 200,000 years by analysing algae, insect fossils and geochemical traces in sediment cores extracted from the 40ha lake.

The cores stretch back 80,000 years further than existing Greenland ice cores, revealing environmental conditions prevalent during two earlier Ice Ages and three interglacial periods.

Researchers found that several types of mosquito-like midges that for many thousands of years thrived in cold climate surrounding the lake suddenly began declining at around 1950; two midge species adapted to the coldest weather disappeared altogether.

Midges starting to disappear around the same time that Canada is increasing its’ wheat production and use of pesticides. Who is this clown and is his office next door to Ward Churchills?

The key words are ‘likely’. Which is not definitive. they don't know for sure other wise they would say so. So just more dribble from so called scientists.

Researchers found that several types of mosquito-like midges that for many thousands of years thrived in cold climate surrounding the lake suddenly began declining at around 1950; two midge species adapted to the coldest weather disappeared altogether.

So these midges flourished through the Medieval Warm Period? And survived the Global Warming scare of the 1930s? Only to fall victim to AGW in 1950. Too bad they couldn't have held on to the Coming Ice Age of the 1970s!

Is it just me or are the champions of AGW getting nuttier and nuttier?

Despite every Tom, Dick, Harry coming out with their own study, the public is beginning to see this global warming for the fraud that it is.

Something smells very funny here. I believe Baffin was completely glaciated during the last ice age - so how did lake sediments older than 18,000 years survive?

Let’s don’t call it Global warming.

Let’s call it an “ Interglacial Period “
since we’ve had several already, and now another.

No, we're still warming from the last glacial period. Plus, we're still warming from the Little Ice Age.

Researchers were able to reconstruct the local climate over the past 200,000 years by analyzing algae, insect fossils and geochemical traces in sediment cores extracted from the 40ha lake. The cores stretch back 80,000 years further than existing Greenland ice cores,

200,000 years is 80,000 longer than Greenland??? The Greenland cores actually go back more than 400,000 years and through four cycles. Is this guy lying or is he that ignorant?

In the 1970s they were doing their best to scare us all about the coming ice age. Looks like we saved ourselves from freezing to death with all of our human activity.

Or were they wrong about the ice age? Or are they wrong about human activity causing climate change?

Personally, I think they need a diaper change. It's clear they have nothing but sh1t for brains and they've pooped themselves all the way to imbecility.

If you just sample 200000 years you might conclude that, but the earth and the solar system work on a much different time scale. It is clear from the Vostok 420000 year ice core sample that there is a recurring pattern of about a 120,000 years. http://en.wikipedia.org/wiki/Ice_core I wonder how much human activity contributed to it 120,000, 240,000, 360,000 years ago? None!!!!

It is interesting that other planets have in our solar system have gone through the same warming cycle, and they have no humans on them. Hmm....could it be the sun?!!

Also for those who understand basic science, CO2 is a regulating cooling gas that absorbs long wavelength radiation. What happens to a gas that warms? It rises and pulls the heat AWAY from the surface to the upper atmosphere. At night when there is no sun the CO2 cools and falls back to earth to be absorbed by plants, the oceans, etc.

You want to save the planet, plant a tree.

But the sun always makes me sneeze. It’s a neurological phenomenon that doctors can’t really explain. I think it’s a natural reaction to keep one from staring at the sun. Or maybe it’s limited to people with light eyes.

Nuttier by the hour.

I wonder how many thousands of things beside Al Gore's global warming could have been responsible for the demise of the midges?

It's certainly not limited to people with light eyes - my eyes are quite dark and sunlight triggers sneezes in me. I seem to recall it being referred to as a "photic sneeze" (triggered by light).

I've read some speculation that it's a holdover response to first seeing the sun after emerging from a dark cave. The sneeze would supposedly clear the nose of accumulated junk from being in the cave.

Two things.

1.) How do they determine "GLOBAL" trends from the experience of one isolated place. They always said you can't tell how hot it's getting whenever there's a cold snap.

2.)They have 200,000 years of sediment cores they have taken. There is no way they can devine a 60 year trend in that. 1,000 years maybe, 10,000 years probably, yet they only have the current records going back 60 years.

People see what they want to see.

I’ve always thought it might be that the sensors or nerves for the sinuses and the eyes are so close together that sometimes the signals get “crossed”. And an eye irritant (the bright sun) sometimes gets picked up as nasal irritation. I often will look at a ceiling light to get out a hesitant sneeze to give it an extra “push”!

From now until the Copenhagen conference is over, we can expect these "scheduled" stories to come out one at a time and all of which have already been discredited.

They have had this stuff a planned out for quite a while now.

They should have planned the meeting for summer months because we are due for some cold weather that will fly in the face of their theories.

Did anyone else note the glaring peculiarity of this information?

That is, the headline is about *geology*, sediment samples, and suddenly there is a segue right into *biology*, about midges.

This sounds suspiciously like looking for data to support the conclusions they have already reached. So let’s look further.

They say that they have data in the sediment going back 200,000 years, and yet the last 60 years have been markedly different. Since they did this with a core sample, how much of that core sample is the last 60 years?

1/3,333th and a third of however large that core sample. 200,000 divided by 60. So how big is that core sample?

For the sake of argument, let’s assume it is a really big one, 10 meters in length. That’s about 32.8 feet. About 1/3rd the length of a football field. Even at that scale, the last 60 years is about 3 millimeters in thickness.

And that 3 millimeters, of an improbably long core sample, is the *last* 3 millimeters, far less affected by compression than a sample, say, 7 meters down.

But how about them midges, huh?

"We see clear evidence for warming in one of the most remote places on Earth at a time when the Arctic should be cooling because of natural processes."

Mr Axford is the chief author of the study published in the Proceedings of the National Academy of Sciences.

For thousands of years, environmental changes in a remote lake on Canada's Baffin Island closely matched natural, cyclical climate changes such as those caused by the Earth's periodic wobble as it swings around the sun, the researchers said.

However, lake sediment cores dating from 1950 show that expected climate cooling was overridden by human activity like greenhouse gas emissions.

Researchers were able to reconstruct the local climate over the past 200,000 years by analysing algae, insect fossils and geochemical traces in sediment cores extracted from the 40ha lake.

Interesting.

At the Institute we have been vocal about putting any faith in the Global Climate Models for many reasons - all modeling assumes one knows all the angles and all the pathways; and that is total hubris, especially as far as Earth's climatic variation. In the philosophical sense modelling is hardly science at all, but to a degree humanistic fantasy, like movies or Christmas train gardens.

In this report however if it is legitimate, and one can't dismiss PNAS, there is evidence something is recently environmentally out of whack with Earth's precessional (wobble) period. If one looks at 200,000 years of reliable periodic association then sees something incongruent, then there is apparently something unique happening.

But this statement:

However, lake sediment cores dating from 1950 show that expected climate cooling was overridden by human activity like greenhouse gas emissions.

is really ignorant and quite annoying; hopefully it wasn't the scientists who made it. It exposes the bigotry associated with the whole anthropogenic claim. There is little reason whatsoever to associate the incongruent happening to anthropogenic causes when such dramatic variations have occurred during other era's when SUV's did not exist - if of course such incongruent happenings did indeed occur when SUV's did not exist.

Which means to make any argument at all for "human activity like greenhouse gas emissions," a greater geological perspective is needed to rule out non-anthropogenic causes. That is to say no one is denying global warming occurs or that it has occurred during humanity's industrialization; but to say that industrialization is the cause of global warming is bogus until proven; and given that CO2 has been significantly higher in the geological past with its subsequent reduction and while life on Earth prospered, there is no reason to react unscientifically (as so many politicians routinely do).
