Confirmation of AGW

[Procrustes Stretched]

In the end most of the deniers of science will come around and acknowledge real science with the caveat that it isn't all human fault and it isn't as bad as some have claimed. Which will beg the question (among others): Why did they have to deny the science rather than argue the merits of policy?

In the end, climate science is going to implode upon itself and maybe something akin to real science will start happening after the implosion.

You just posted a claim that the earth is warmer now than it has been in the past 11,300 years. We know beyond question from literally hundreds of studies that the holocene maximum about 6000 years ago was most certainly warmer than the present. We also know that both the Roman and Medieval warm periods were both warmer than the present and global in nature. Again, dozens upon dozens of studies bear this out.

The claim that the present is warmer than not only the roman and medieval warm periods, but the holocene maximum is simply idiocy at its best.

see? you are doing it now.

Global temperatures are close to 11,000-year peak : Nature News & Comment

Global average temperatures are now higher than they have been for about 75% of the past 11,300 years, a study suggests. And if climate models are any indication, by the end of this century they will be the highest ever since the end of the most recent ice age.

Instrumental records of climate extend back to only the late nineteenth century. Beyond that, scientists depend on analyses of natural chronicles such as tree rings and isotope ratios in cave formations.

But even these archives have their limits: many detailed reconstructions of climate, particularly of temperature, apply to only limited regions or extend back at most a couple of millennia, says Shaun Marcott, a climate scientist at Oregon State University in Corvallis.

Marcott and his colleagues set about reconstructing global climate trends all the way back to 11,300 years ago, when the Northern Hemisphere was emerging from the most recent ice age. To do so, they collected and analysed data gathered by other teams. The 73 overlapping climate records that they considered included sediment cores drilled from lake bottoms and sea floors around the world, along with a handful of ice cores collected in Antarctica and Greenland.

More confirmation of the unnatural nature of the recent global warming.

Dammit! If we could have gotten rid of those SUVs, evil corporations, coal producing plants and the like, 11,000 years ago, we'd not be in this mess today!

see? you are doing it now.

Doing what, pointing out the obvious flaw in your claims? Someone needs to since you obviously can't see it. The holocen maximum, the roman and medieval warm periods are well documented to have been both warmer than the present and global in nature and yet, you claim that the present is warmer than those well documented warm periods.

Scientists: Earth is warmer today than any time in the past 11,300 Years

Earth is getting warmer.

Science Recorder | Delila James | Saturday, March 09, 2013

It’s a significant finding in the world of climate science.

Comprehensive new research into global climate change finds that our planet is warmer today than at any time during the last 11,300 years. The study, published in the journal Science, examined variations in temperature over the past 15,000 years, during the relatively warm Holocene period, which began at the close of the last great ice age and continues to the present day.

Researchers from Oregon State University and Harvard used core samples from 73 ice and sediment core monitoring sites around the globe to reconstruct global temperature change by studying fossils of marine microorganisms.

...

That said, the study is likely to be met with skepticism from individuals questioning whether human action is behind warming trends, and whether warming trends are actually occurring. The Science study comes just weeks after researchers in Norway announced findings that seem to support the notion that global warming is less severe than previously predicted by the United Nations climate authority. The study also found that meeting targets for minimizing global warming may be more achievable than previously thought.

In the end most of the deniers of science will come around and acknowledge real science with the caveat that it isn't all human fault and it isn't as bad as some have claimed.

the deniers will have to come around, and watch them switch gears/move the goal posts:

Previous climate histories have mainly focused on changes over the past 2,000 years, but the new data puts today’s climate change into a much broader and long-term context, according to lead author on the study, OSU paleoclimatologist Shaun Marcott.

Earlier studies have relied primarily on analysis of tree rings, lake sediment cores and isotope ratios in cave formations. Although such studies can provide detailed reconstructions of climatic change, they typically apply only to limited geographical regions and do not extend back more than a couple of thousand years, says Marcott. Marcott’s study, on the other hand, fills in the crucial post-ice age time during early human civilization.

In addition, the study represents one of the first attempts to build a set of data from sites around the world

Green fatigue sets in: the world cools on global warming - Climate Change - Environment - The Independent


Nobody cares s0n........as we will soon see when Climate Legislation goes down in flames in the Congress. Of course, the environemntal OC's might miss the news......not to worry. I'll be on here the very same day to announce it via tons of gay MSPAINT Photobucket Classics.


And the next day, the dickheads will be right back to telling us about "YOU DENIERS!!!"


And I'll be laughing my balls off.


Every time I pop in here, I feel like I'm busting up a session in group navel contemplation.

Global temperature rise is fastest in at least 11,000 years, study says - CSMonitor.com

"To our knowledge, based on this reconstruction, the rate of change today is unprecedented" in the Holocene, says Shaun Marcott, an atmospheric scientist at Oregon State University who led a team formally reporting the results in Friday's issue of the journal Science. Indeed, it may be unprecedented in the past 22,000 years, he adds, when previous paleoclimate research he and his colleagues have conducted is taken into account.

Other researchers have focused on the Holocene as well, notably Michael Mann, a Penn State University climatologist, and his colleagues. But their reconstructions have taken the record back only about 1,500 years.

The new work, using different thermometer stand-ins, or proxies, not only reaches results similar to these previous efforts covering the recent past. It also accounts for natural variations in climate over longer time scales in ways that suggest rising temperatures will exceed the range of natural fluctuations. The long-term variations would include changes in Earth’s orbit, for instance.

Based on the reconstructed temperatures records, natural variability over the study's time span accounts for roughly 1 degree C from coldest to warmest compared with the current climate, observes David Anderson, branch chief for the Paleoclimate Program in at the National Oceanic and Atmospheric Administration's National Climatic Data Center office in Boulder, Colo.

"If you go grab the mount of warming expected just within the next 80 years, that's more like 3 degrees," says Dr. Anderson, who was not a member of the study team – three times the change one would expect from natural variability alone, and all in the warm direction.

I`ll go back after I post this and click on the thank you button of your post, because you brought up another typical, if not thee most typical flaw in "climatology"...which is linking every climate event in the past to CO2 ....while deliberately ignoring all the other recorded factors that are known to have triggered most of the events the study you quoted names.

NASA - Explosions in Space May Have Initiated Ancient Extinction on Earth

With the ozone layer damaged for up to five years, harmful ultraviolet radiation from the Sun would kill smaller life-forms and disrupt the food chain. Scientists say that a gamma-ray burst might have caused the Ordovician extinction 450 million years ago, some 200 million years before dinosaurs. I
"A gamma-ray burst originating within 6,000 light years from Earth would have a devastating effect on life," said Dr. Adrian Melott of the Department of Physics and Astronomy at the University of Kansas. "We don't know exactly when one came, but we're rather sure it did come -- and left its mark. What's most surprising is that just a 10-second burst can cause years of devastating ozone damage."

In the new work, the team used detailed computer models to calculate the effects of a nearby gamma-ray burst on the atmosphere and the consequences for life.

Thomas, with Dr. Charles Jackman of NASA's Goddard Space Flight Center in Greenbelt, Md., calculated the effect of a nearby gamma-ray burst on the Earth's atmosphere. Gamma rays, a high-energy form of light, can break molecular nitrogen (N2) into nitrogen atoms, which react with molecular oxygen (O2) to form nitric oxide (NO). NO will destroy ozone (O3) and produce nitrogen dioxide (NO2). NO2 will then react with atomic oxygen to reform NO. More NO means more ozone destruction. Computer models show that up to half the ozone layer is destroyed within weeks. Five years on, at least 10 percent is still destroyed.

I did post a correlation in the thread that the usual trolls bury with their copy-paste & post entire screen page over sized fat print minutes after anyone posts some facts they can`t handle.
Here is a reality check.
Physicists that study the effects of solar flares and gamma bursts can show you a r^2 correlation better than 75 % with observed temperatures...while climatology has a problem, even with the "adjusted data set" to get a r-correlation of ~ 20 %
Alone from 2000 to 2012 we have observed 8 such intense gamma ray bursts. While studies like the one you quote have been attributing everything under the sun to CO2 and have you believe that none of that has happened during the last 22 000 years :
One Of Brightest Gamma-Ray Bursts Ever Seen

Apr. 3, 2009 — Europe's Integral satellite has captured one of the brightest gamma-ray bursts ever seen.

It has been confirmed by fossil records decades ago that earth has had several direct hits that were at an extinction level magnitude down to precisely the depth that lethal UV light can penetrate water when the ozone layer was nuked by gamma rays.

Solar Changes and the Climate
By Joseph D’Aleo
The IPCC AR4 discussed at length the varied research on the direct solar irradiance variance and the uncertainties related to indirect solar influences through variance through the solar cycles of ultraviolet and solar wind/geomagnetic activity. They admit that ultraviolet radiation by warming through ozone chemistry and geomagnetic activity through the reduction of cosmic rays and through that low clouds could have an effect on climate but in the end chose to ignore the indirect effect
For the total solar forcing, in the end the AR4 chose to ignore the considerable recent peer review in favor of Wang et al. (2005) who used an untested flux transport model with variable meridional flow hypothesis and reduced the net long term variance of direct solar irradiance since the mini-ice age around 1750 by up to a factor of 7. This may ultimately prove to be AR4’s version of the AR3’s “hockey stick” debacle.
Richard Willson, principal investigator of NASA’s ACRIM experiments though in the GRL in 2003 was able to find specific errors in the dataset used by Lean and Froelich used to bridge the gap between the ACRIM satellites and when the more accurate data set was used a trend of 0.05% per decade was seen which could account for warming since 1979
Two other recent studies that have drawn clear connections between solar changes and the Earth’s climate are Soon (2005) and Kärner (2004). Soon (2005 GRL) showed how the arctic temperatures (the arctic of course has no urbanization contamination) correlated with solar irradiance far better than with the greenhouse gases over the last century (see Figure 3). For the 10 year running mean of total solar irradiance (TSI) vs Arctic-wide air temperature anomalies (Polyokov), he found a strong correlation of (r-squared of 0.79) compared to a correlation vs greenhouse gases of just 0.22.
Figure

And that deals only with what our sun has been dishing out, never mind the gamma ray bursts that have been at extinction level magnitude since life existed on earth.
These have been so well documented that even pro "AGW" TV channels like National Geographic, The discovery Channel etc were running several documentaries on that subject since about 5 years. The only way anyone interested in climate history could miss it if they had their head buried in "skepticalscience.com" blogs and the like, day in day out all day long for 5 years.

I claim nothing. I linked to and quoted what scientists have said.

Of course you do. By posting that article as support for your position, you implicitly make the claim and use the article as support for your cliam.

It just turns out that your claim is wrong and literaly hundreds of peer reviewed publishedp papers support my claim that your claim is false.

If the earth is a few degrees warmer we'll all be just fine.

What a load of horse shit. Because temperatures seem unnatural to you that it must be proof of man made global warming. This is by far the dumbest post I've ever read to date on the subject of the Great Climate Change Hoax... And I've read quite a lot of them. Bravo Old Rocks!!! you've managed to lower the bar of the AGW stupidity even further.

Me to. These guys go on and on about impending disaster but I haven't seen the first shred of proof that the earth is presently at its optimum temperature for life. Personally, I think a degree or two warmer would be a good thing...longer growing seasons...more of the earth in prime growing zones...etc. Not to mention lower heating bills etc.

So instead of a few sets of unconfirmable, implied data, they collected a whole BUNCH of sets of unconfirmable, implied data.

At least it's data. Deniers only argument is that data is not worth looking at.

Let me guess, you think computer models are "data" too don't you?

 

[westwall]

You said confirmation of AGW. You haven't even confirmed that present temperatures are the highest ever (not even close by the way)...where is the proof there, or even strongly compelling evidence that man is the cause for the present temperatures?

By the way, I looked for some indication of where either of those "studies" had been published. No mention of publishing or peer review. Self published opinion is what they looked like and about as much credential as they can claim.

Recent Heat Spike Unlike Anything in 11,000 Years - SKYE on AOL


Research released Thursday in the journal Science uses fossils of tiny marine organisms to reconstruct global temperatures back to the end of the last ice age. It shows how the globe for several thousands of years was cooling until an unprecedented reversal in the 20th century.

The temperatures of the planet have always changed. I am 99% convinced that some of this change is man-made. The validity of the argument for global warming, however, has been trashed by 'watermelons' - those who use the climate for political gain. Those people are the real villains. Take the politics out of the environment.

"The validity of the argument for global warming" is established by the actual science, not by your idiotic and partisan analysis of the politics. The political side of this is being primarily driven by the rightwingnuts like yourself. If we take the politics out of the environmental debates, all that's left is the science and the science is very clear that the Earth is warming rapidly due to mankind's activities and that this warming will increasingly affect and disrupt the Earth's climate patterns to the detriment of our human civilization.

Old Rocks- I know that in the past I have told you that you cannot splice the thermometer record on to paleo reconstructions because they are different types of data. the resolution is much coarser in proxy data therefore the variation is reduced. here is a good primer on what our temp record would look like at something like the resolution of Marcott's curve.

the little red line at the end. not very newsworthy if you ask me.
