Climate Change Deniers are Almost Extinct

Kinda like the Medieval Warming Period, huh?

Oh, wait -- that really happened. Never know it from AGW "science", though.

Reconstructing the climate of medieval Europe | Ars Technica

To try and understand the temperature variations, the researchers then examined correlations between their climate reconstruction and known volcanic activity and solar activity. They found at least one cold year in the following three years after major volcanic eruptions. Generally, warm years coincided with years of high solar activity, and vice versa. The one exception was at the end of the medieval warm period; the researchers speculate that deforestation in Europe may have increased the local albedo enough to compensate for the solar activity.

With all that established, what of the medieval warm period? Well, the weather was certainly warmer in Northern Europe and in the North Atlantic, but it was colder and more variable in Southern Europe. After roughly 1400 CE, the less stable weather expanded to Northern Europe and both areas cooled.

The little ice age, on the other hand, was common to most of the continent. The point is that if one used just Northern Europe's tree ring data, the medieval warm period would look very strong, while Southern European proxies would show no warm period. Only by combining data from throughout Europe can one see just how local the medieval warm period actually was.

This is pretty much what climatologists had concluded already—at least as far as the medieval warm period goes. What's important in the new way is that the temperature reconstruction drawn from the proxies resulted in what seems to be a more accurate temperature reconstruction. Because the calibration was internal, the different proxy data sets could be more accurately combined with each other and used to draw much stronger conclusions than previously.

Proxy-based reconstructions of hemispheric and global surface temperature variations over the past two millennia

Following the suggestions of a recent National Research Council report [NRC (National Research Council) (2006) Surface Temperature Reconstructions for the Last 2,000 Years (Natl Acad Press, Washington, DC).], we reconstruct surface temperature at hemispheric and global scale for much of the last 2,000 years using a greatly expanded set of proxy data for decadal-to-centennial climate changes, recently updated instrumental data, and complementary methods that have been thoroughly tested and validated with model simulation experiments. Our results extend previous conclusions that recent Northern Hemisphere surface temperature increases are likely anomalous in a long-term context. Recent warmth appears anomalous for at least the past 1,300 years whether or not tree-ring data are used. If tree-ring data are used, the conclusion can be extended to at least the past 1,700 years, but with additional strong caveats. The reconstructed amplitude of change over past centuries is greater than hitherto reported, with somewhat greater Medieval warmth in the Northern Hemisphere, albeit still not reaching recent levels.

There are dozens of "educational" programs on TV today that give credible evidence for "Bigfoot" and "para-normal sightings". The same phony pseudo-science and fudged data and biased crazy hype is used by the international left to promote the phony crisis of "global-warming" as an extortion scheme to bring America to it's knees in a time of economic unrest.

Oh my, another dumb fuck equating silly programs on TV to articles in peer reviewed scientific journals. But then, if one only watchs such programs, and never reads such journals, what can you expect of them

The above chart shows the correlation between the Obama and FDR Administrations and Midwest droughts. Pretend for a moment, using Michael's Mann substitution of Data method that instead of 0-1000, the numbers at the bottom range from 1920-2010, the assume that the range on the left is the relative Progressiveness of the Presidential Administration, finally the purple lines are US Presidents and the black line is Midwest droughts.

As you can see there is as perfect correlation between severe drought and the Administrations of FDR and Obama.

Progressives create droughts. Clearly, the science is settled.

I have peer-reviewed this post, and can find no fault with its conclusions.

Not so fast FauxdiRocks.. You're quoting one Hockey Stick era study that was there to confirm the flatness of the previous surface temp record.. The REAL SCORECARD is below...

Note the number of studies that show the MWP to be significant and EXCEEDING the common era warming. I'm supposing that your effort to save Mann's silly ass exceeds your conscience to even CONSIDER the majority report on the topic..

So you are relying on MINORITY consensus to make the case that something this significant DID NOT HAPPEN.. In fact -- I HATE tree rings and mud sediments, but there is AMPLE evidence for a GLOBAL impact of the MWP.

Medieval Warm Period - Wikipedia, the free encyclopedia

The 2009 Mann et al. study found warmth exceeding 1961–1990 levels in Southern Greenland and parts of North America during the Medieval climate anomaly (defined for this purpose as 950 to 1250) with warmth in some regions exceeding temperatures of the 1990–2010 period. Much of the Northern hemisphere showed significant cooling during the Little Ice Age (defined for the purpose as 1400 to 1700) but Labrador and isolated parts of the United States appeared to be approximately as warm as during the 1961–1990 period.[8]

The Vikings took advantage of ice-free seas to colonize Greenland and other outlying lands of the far north.[21] A settlement was found and excavated at L'Anse aux Meadows by Helge Ingstad, for example. Around 1000AD the climate was sufficiently warm for the north of Newfoundland to support a Viking colony and led to the descriptor "Vinland". The MWP was followed by the Little Ice Age, a period of cooling that lasted until the 19th century, and the Viking settlements vanished from history



The MWP has been noted in Chile in a 1500-year lake bed sediment core . [33]

Adhikari and Kumon (2001), whilst investigating sediments in Lake Nakatsuna in central Japan, finding a warm period from AD 900 to 1200 that corresponded to the Medieval Warm Period and three cool phases, of which two could be related to the Little Ice Age.[34] Another research in northeastern Japan shows that there is one warm/humid interval from AD 750 to 1200, and two cold/dry intervals from AD 1 to 750 and 1200 to present.[7] Ge et al. studied temperatures in China during the past 2000 years; they found high uncertainty prior to the 16th century but good consistency over the last 500 years, highlighted by the two cold periods 1620s–1710s and 1800s–1860s, and the warming during the 20th century. They also found that the warming during the 10–14th centuries in some regions might be comparable in magnitude to the warming of the last few decades of the 20th century which was unprecedented within the past 500 years.[35]

A 1979 study from the University of Waikato found that "Temperatures derived from an 18O/16O profile through a stalagmite found in a New Zealand cave (40.67°S, 172.43°E) suggested the Medieval Warm Period to have occurred between AD 1050 and 1400 and to have been 0.75 °C warmer than the Current Warm Period."[36] The MWP has also been evidenced in New Zealand by an 1100-year tree-ring record.[37]

A reconstruction based on ice cores found the Medieval Warm Period could be distinguished in tropical South America from about 1050 to 1300, followed in the 15th century by the Little Ice Age. Peak temperatures did not rise as high as those from the late 20th century, which were unprecedented in the area during the study period going back around 1600 years

I love the opening paragraph....Interesting how a colony that existed for 500 years (longer than most of the countries of the Earth have been around) is considered "short lived", that the colony involved consisted of between 5,000 and 13,000 individuals, and that as a percentage that equals between 5 and 10 percent of the ENTIRE Viking population. Clearly they are both history and logic challenged.


"One of the uncertainties in climate science is figuring out how global climate trends translate into local predictions and reconstructions, and vice versa. A classic example of this is the medieval warm period, the time when Vikings roamed the North Sea and North Atlantic in shallow-draft open boats. They settled Greenland and made periodic visits to North America to get timber, placing some short-lived settlements there. "

But when you're whoring out propaganda little things like facts don't matter....do they olfraud. You're a classic example of that.

Not so fast FauxdiRocks.. You're quoting one Hockey Stick era study that was there to confirm the flatness of the previous surface temp record.. The REAL SCORECARD is below...

Note the number of studies that show the MWP to be significant and EXCEEDING the common era warming. I'm supposing that your effort to save Mann's silly ass exceeds your conscience to even CONSIDER the majority report on the topic..

So you are relying on MINORITY consensus to make the case that something this significant DID NOT HAPPEN.. In fact -- I HATE tree rings and mud sediments, but there is AMPLE evidence for a GLOBAL impact of the MWP.

Medieval Warm Period - Wikipedia, the free encyclopedia

The 2009 Mann et al. study found warmth exceeding 1961–1990 levels in Southern Greenland and parts of North America during the Medieval climate anomaly (defined for this purpose as 950 to 1250) with warmth in some regions exceeding temperatures of the 1990–2010 period. Much of the Northern hemisphere showed significant cooling during the Little Ice Age (defined for the purpose as 1400 to 1700) but Labrador and isolated parts of the United States appeared to be approximately as warm as during the 1961–1990 period.[8]

The Vikings took advantage of ice-free seas to colonize Greenland and other outlying lands of the far north.[21] A settlement was found and excavated at L'Anse aux Meadows by Helge Ingstad, for example. Around 1000AD the climate was sufficiently warm for the north of Newfoundland to support a Viking colony and led to the descriptor "Vinland". The MWP was followed by the Little Ice Age, a period of cooling that lasted until the 19th century, and the Viking settlements vanished from history



The MWP has been noted in Chile in a 1500-year lake bed sediment core . [33]

Adhikari and Kumon (2001), whilst investigating sediments in Lake Nakatsuna in central Japan, finding a warm period from AD 900 to 1200 that corresponded to the Medieval Warm Period and three cool phases, of which two could be related to the Little Ice Age.[34] Another research in northeastern Japan shows that there is one warm/humid interval from AD 750 to 1200, and two cold/dry intervals from AD 1 to 750 and 1200 to present.[7] Ge et al. studied temperatures in China during the past 2000 years; they found high uncertainty prior to the 16th century but good consistency over the last 500 years, highlighted by the two cold periods 1620s–1710s and 1800s–1860s, and the warming during the 20th century. They also found that the warming during the 10–14th centuries in some regions might be comparable in magnitude to the warming of the last few decades of the 20th century which was unprecedented within the past 500 years.[35]

A 1979 study from the University of Waikato found that "Temperatures derived from an 18O/16O profile through a stalagmite found in a New Zealand cave (40.67°S, 172.43°E) suggested the Medieval Warm Period to have occurred between AD 1050 and 1400 and to have been 0.75 °C warmer than the Current Warm Period."[36] The MWP has also been evidenced in New Zealand by an 1100-year tree-ring record.[37]

A reconstruction based on ice cores found the Medieval Warm Period could be distinguished in tropical South America from about 1050 to 1300, followed in the 15th century by the Little Ice Age. Peak temperatures did not rise as high as those from the late 20th century, which were unprecedented in the area during the study period going back around 1600 years

Ice cores, and sediments and tree rings --- Oh MY! Ice cores and sediments and tree rings -- OH MY !!!!

Oh my, a crap post quoting a crap site. Of course Flatulance, Walleyes and the rest of the cadre of willfull ignorance would put more credance in that than a PNAS publication. After, what do those damned scientists know?

Climate Change Deniers are Almost Extinct

Kinda like the Medieval Warming Period, huh?

Oh, wait -- that really happened. Never know it from AGW "science", though.

Another ignoramous chimes in on what he knows nothing of.

Reconstructing the climate of medieval Europe | Ars Technica

To try and understand the temperature variations, the researchers then examined correlations between their climate reconstruction and known volcanic activity and solar activity. They found at least one cold year in the following three years after major volcanic eruptions. Generally, warm years coincided with years of high solar activity, and vice versa. The one exception was at the end of the medieval warm period; the researchers speculate that deforestation in Europe may have increased the local albedo enough to compensate for the solar activity.

With all that established, what of the medieval warm period? Well, the weather was certainly warmer in Northern Europe and in the North Atlantic, but it was colder and more variable in Southern Europe. After roughly 1400 CE, the less stable weather expanded to Northern Europe and both areas cooled.

The little ice age, on the other hand, was common to most of the continent. The point is that if one used just Northern Europe's tree ring data, the medieval warm period would look very strong, while Southern European proxies would show no warm period. Only by combining data from throughout Europe can one see just how local the medieval warm period actually was.

This is pretty much what climatologists had concluded already—at least as far as the medieval warm period goes. What's important in the new way is that the temperature reconstruction drawn from the proxies resulted in what seems to be a more accurate temperature reconstruction. Because the calibration was internal, the different proxy data sets could be more accurately combined with each other and used to draw much stronger conclusions than previously.

Proxy-based reconstructions of hemispheric and global surface temperature variations over the past two millennia

Following the suggestions of a recent National Research Council report [NRC (National Research Council) (2006) Surface Temperature Reconstructions for the Last 2,000 Years (Natl Acad Press, Washington, DC).], we reconstruct surface temperature at hemispheric and global scale for much of the last 2,000 years using a greatly expanded set of proxy data for decadal-to-centennial climate changes, recently updated instrumental data, and complementary methods that have been thoroughly tested and validated with model simulation experiments. Our results extend previous conclusions that recent Northern Hemisphere surface temperature increases are likely anomalous in a long-term context. Recent warmth appears anomalous for at least the past 1,300 years whether or not tree-ring data are used. If tree-ring data are used, the conclusion can be extended to at least the past 1,700 years, but with additional strong caveats. The reconstructed amplitude of change over past centuries is greater than hitherto reported, with somewhat greater Medieval warmth in the Northern Hemisphere, albeit still not reaching recent levels.

Sure, if your sole gauge for what constitutes a scientist is "how much he parrots AGW orthodoxy".

The tree ring data is horseshit.

McIntyre noticed a few problems with the way Briffa chose the sampling of Russian trees, and he wrote to Briffa requesting the data Briffa used in a published tree-ring paper. Briffa declined. And so began a four-year saga involving multiple peer-reviewed journals, behind-the-scenes maneuvering by Briffa and his closest confidants, and a Freedom of Information Act request on the part of McIntyre that appears to be on the verge of being granted. Even without the final set of data, however, McIntyre has shown beyond the shadow of doubt that Briffa may have committed one of the worst sins, if not the worst, in climatology — that of cherry-picking data — when he assembled his data sample, which his clique of like-minded and very powerful peers have also used in paper after paper.

It was already known that the Yamal series contained a preposterously small amount of data. This by itself raised many questions: Why did Briffa include only half the number of cores covering the balmy interval known as the Medieval Warm Period that another scientist, one with whom he was acquainted, had reported for Yamal? And why were there so few cores in Briffa’s 20th century? By 1988, there were only twelve cores used in a year, an amazingly small number from the period that should have provided the easiest data. By 1990, the count was only ten, and it dropped to just five in 1995. Without an explanation of how the strange sampling of the available data had been performed, the suspicion of cherry-picking became overwhelming, particularly since the sharp 20th-century uptick in the series was almost entirely due to a single tree.

--

But the ruse has now been shot to pieces, by the recent decision from the U.K.’s information commissioner that Briffa can no longer withhold the list of sites he used in his suppressed regional record for the Yamal area. The disclosure of these sites has allowed McIntyre to calculate what the broad series would have looked like if Briffa had chosen to publish it. He has shown that it has no hint of the hockey-stick shape that Briffa’s cherry-picked data indicated. Briffa’s decision to publish an alarming but unreliable version of the Yamal series — instead of a more reliable and thoroughly unremarkable one — has been the talk of the climate blogosphere, with many prominent commentators openly speaking of dishonesty.​

You've been lied to. But you love the lies so you believe them.

Moron.

The above chart shows the correlation between the Obama and FDR Administrations and Midwest droughts. Pretend for a moment, using Michael's Mann substitution of Data method that instead of 0-1000, the numbers at the bottom range from 1920-2010, the assume that the range on the left is the relative Progressiveness of the Presidential Administration, finally the purple lines are US Presidents and the black line is Midwest droughts.

As you can see there is as perfect correlation between severe drought and the Administrations of FDR and Obama.

Progressives create droughts. Clearly, the science is settled.

I have peer-reviewed this post, and can find no fault with its conclusions.

For sure, you and Frankie Boy are peer level.

Not sure about Frank, but I finished college. You?

Government funded "researchers" will come up with any skewed data results that keep the government grant money flowing. That's a political axiom you can hang your hat on. We don't have time for this extortion racket while the US is coping with unemployment and the freaking world is coping with civil unrest. Let's table the global warming issue for ten or twenty years while we get our economic situation together.

That will be too long! The world will catch fire from all the heat generated by CO2. But at least the fires will be put out by the rising oceans.
