Easterbrook on the magnitude of Greenland GISP2 ice core data

Watts Up With That? ^ | January 24, 2011 | Anthony Watts

None of these changes could have been caused by changes in atmospheric CO2 because they predate the large CO2 emissions that began about 1945.

So what do the Global Warming huts have to say now?

[TigersEye]

Unless all of those ice cores and the way they are interpreted is completely and utterly wrong this is proof positive that there is no AWG and CO2 has no effect on the climate.

But then ice cores are far from the only proof of these historical temperature swings.

The GISP2 Greenland ice core has proven to be a great source of climatic data from the geologic past. Ancient temperatures can be measured using oxygen isotopes in the ice and ages can be determined from annual dust accumulation layers in the ice... The age of each sample is accurately known from annual dust layers in the ice core. The top of the core is 1987. The d18O data clearly show remarkable swings in climate over the past 100,000 years. In just the past 500 years, Greenland warming/cooling temperatures fluctuated back and forth about 40 times, with changes every 25-30 years (27 years on the average). None of these changes could have been caused by changes in atmospheric CO2 because they predate the large CO2 emissions that began about 1945. Nor can the warming of 1915 to 1945 be related to CO2, because it pre-dates the soaring emissions after 1945. Thirty years of global cooling (1945 to 1977) occurred during the big post-1945 increase in CO2.

...If CO2 is indeed the cause of global warming, then global temperatures should mirror the rise in CO2...

Well, one would think. I have reached the very sad conclusion that many of today's so-called "scientists" (and I also include many medical researchers here) cannot discern the difference between coincidence and correlation.

I, of course, have absolutely no proof for this theory.

Could you imagine the headlines back in those days?

"Temperatures drop unexpectedly.

[Marine_Uncle]

The flow of information coming forth in easy to read form should further help US Rep Daryl Issa and his staff formulate solid arguments as to why the EPA must stop any restrictions related to carbon dioxide emissions.
Then they can start to go after the NASA GISS gang. Public relations is important. They must make it a point to inform the L/MSM and public via. various means as to why the CO2 issue should finally be put to rest, forever. And why Carbon Trading Exchanges are simply schemes to cripple industry as well as our over all economic condition from really getting totally out of whack.

The data looks correct, and seems to jive with the Vostok Ice core data.

Is there global warming? Yes.
Is it man made? Hell no.

The same cycles have repeated over and over for the last 1.2 million years or so.

And the chart says it best: on the left, it says we are in the “Holocene interglacial”

We are right now in the “interglacial maximum”. It’s gonna get colder, folks. Much colder. Cold enough that all the ideas and dreams about “Well, I’ll just grow a few tomato plants...” well, thats pretty much a fantasy.
Not yet, maybe, but in the next 5-15 thousand years.

[aruanan]

Not yet, maybe, but in the next 5-15 thousand years.

If in the next 5-15 thousand years, it'll be delayed between about 50-150% of the length of the typical interglacial of the last five (including this one, that is the longest and coolest of them)

[listenhillary]

“Not yet, maybe, but in the next 5-15 thousand years.”

You are making it really hard to scare people into modifying their behavior saying things like that. (/sarcasm off)

[ElkGroveDan]

This data is totally unreliable. It hasn't been “adjusted” yet. </sarcasm>

[SouthTexas]

Several years ago, someone produced data that showed pre-historic O2/CO2 levels. Data was retrieved from bubbles in amber.

Wonder if they can extract that from the ice cores?

[ForGod'sSake]

I’m like, you know, totally mortified; sortof. Why, this Watts guy doesn’t even have a PhD!!! The horror! And this Easterbrook fellow is obviously out of his element. What can a man credentialed with a PhD in geology possibly know about global war..., er, climate change. He just HAS to have rocks in his head. What’s he doing digging around in iceholes anyway? Looking for more rocks; har??? I’m just horrified that anyone would pay attention to these two Neandertahls who obviously have a hidden agenda. I mean really, anyone wanting to kill algore’s cash cow must be a fruitcake, or dimwitted or worse. Maybe TEA Partiers or something. They might be pursuing real science which will not allow the glob.., er, proper infrastructure to be put in place. They just don’t understand that without global governance to mitigate the coming climate change, whichever way it goes, we could all just, well, never mind...

[The Comedian]

OK, so answer the following question:

Are we all gonna die?

[] Yes

[] No

[] Maybe

[] There isn't even enough time left to choose any of the above answers

Frowning takes 68 muscles.
Smiling takes 6.
Pulling this trigger takes 2.
I'm lazy.

A few months ago I engaged in an extended email debate on a college alumni board with some alarmists. I laid out all the ice core data and other scientific arguments against AGW. Over and over. It was like talking to a wall. All I got back was "science" and "settled" and it's been warming since 1850, the world began industrializing about that time, therefore human industrialization causes global warming. Q.E.D.

I finally gave up and left them with my benediction, post hoc ergo propter hoc.
