Putting the Hockey Stick in a Proper Context

Climate Change In Perspective

If you’ve been living under a rock, then you probably haven’t heard of the (now famous) “hockey stick graph.”

OriginalStick

‘Hockey Stick’ was coined by the climatologist Jerry Mahlman, to describe the pattern shown by the Mann, Bradley & Hughes (MBH99) reconstruction, creating a graph that is relatively flat with a downward trend to 1900 which looks like an ice hockey stick’s “shaft” followed by a sharp, steady increase corresponding to the “blade” portion.  The hockey stick graphs have featured in the IPCC reports as evidence of Anthropogenic Global Warming, or AGW.

Note that the time frame of this graph is for 1000 years. That’s barely the blink of an eye in terms of the Earth’s 4.5 billion year existence. Also note that everything prior to 1855, the start point of the red line in the graph above, is not actual direct measurement of temperature, but inferred by proxy.

Greenland Ice Core Proxies

The compacted snow in Greenland Ice Cores above the 1855 level is too recent and not compacted enough to be usable in ice core proxies. But everything prior to that is usable, and goes back nearly 52,000 years.  Greenland ice core data doesn’t go back any farther than that. Temperature estimates are determined by analysing the ratio of Heavy Oxygen and Heavy Hydrogen to normal O and H in the samples of ice.
“Oxygen and hydrogen isotopes in the ice are analyzed to determine hemispheric temperatures because heavy water (water with deuterium instead of 1H), as well as heavy oxygen water, (water with 18O instead of 16O), have higher boiling points than regular water, and more heavy water gets into the atmosphere when global temperatures are high. The warmer the earth, the more heavy isotopes wind up in the ice. This has nothing to do with the temperature of the ice, it has to do with the temperatures at the evaporation sites.” [The evaporation sites from which the ice originated, which for this hockey stick graph are primarily from locations all over the Northern Hemisphere.] – scroll down to ‘Modern Warming’ at this link for a more detailed explanation of Greenland Ice Core Proxy derivations.

The Hockey Stick In Context

If you were startled or alarmed at the original Hockey Stick graph above then you may be even more shocked at what I will show you now! The graphs below will show you this ‘hockey stick’ in a proper context to human and geological history:

Original Hockey Stick (proxy data of Temperature) Graph 1 – 1400AD to 1855AD

The Red arrow points to the blade of the ‘stick.’  The ‘blade’ starts at about 1780.  Coal was only just beginning to be used in industrial applications: it was 1781 when James Watt patented his first continuous motion steam engine.  But not until 1804 when the first railway using a steam engine in Wales took place. 

Graph 2 – looking back to 800AD

hockey2j

Here we see the Medieval Warm Period Circa 1000AD, when the Vikings settled Greenland, and the Little Ice Age, late 1300’s to late 1700’s.

Graph 3 – going back to 2700 BC

hockey3j

1400 BC was even warmer than Roman Warm Period and the Medieval Warm Period. And look what has happened to the ‘hockey stick!’

Graph 4 – Back to 11,000 BC, the last full-on Ice Age

hockey5j

You should be starting to get the picture by now, but we have two more graphs to go:

Graph 5 – 50,000 Years Ago

hockey6j

Here you can see that the ice-age is punctuated by a wildly fluctuating climate pattern with extreme swings between very cold and not so cold periods. You can bet on it that many violent weather events occurred that dwarf anything of the Holocene, which is roughly the last 1/5th of the graph above.

Graph 6 – 425,000 Years Ago [The Last Four Major Glacial Epochs]  Reconstructed global temperature over the past 420,000 years based on the Vostok ice core from the Antarctica (Petit et al. 2001).

The ‘Hockey Stick’ is now an invisible blip in that little red outlined rectangle on the right, which is our current interglacial period. Previous interglacials(Red Spikes) were all warmer than our current one. 

The clock is ticking…

“A model of future climate based on the observed orbital-climate relationships, but ignoring anthropogenic effects, predicts that the long-term trend over the next seven thousand years is toward extensive Northern Hemisphere glaciation.”

And this model is probably correct in ignoring anthropogenic effects because they really don’t amount to much in the long run. And I haven’t even touched on the effects from possible future volcanism which are known to have worldwide repercussions.

Popular Delusions… and Climate Alarmism

In 1841 Charles Mackay first published ‘Memoirs of Historical Popular Delusions.’

It has been re-published many times since, and the title changed to “Extraordinary Popular Delusions and the Madness of Crowds.”
Here is an excerpt from the Foreward:

All economic movements, by their very nature, are motivated by crowd psychology. Graphs and business ratios are, of course, indespensable in our groping efforts to find dependable rules to guide us in our present world of alarms.   Yet I never see a brilliant economic thesis expounding, as though they were geometrical theorems, the mathematics of price movements, that I do not recall Schiller’s dictum: ” Anyone taken as an individual, is tolerably sensible and reasonable–as a member of a crowd, he at once becomes a blockhead,” …

Were this book written today, a whole chapter would have to be added that would be devoted to climate alarmism. And most specifically to the recent (late 20thC to now)  alarmism of the Global Warming variety. Though, to be fair and honest the 20th C. saw from time to time, alarmism of both the Warming, and Cooling varieties, of late, it is the Global Warming variety that has captured the fancy of the crowd much more so than the idea that Earth could be just around the corner from some prolonged cooling event. Indeed, Global Warming/AGW[anthropogenic global warming] terms have been replaced by the current popular term of ‘Climate Change’, which would seem to be a catch-all for whichever way the climate may swing.

Now, you may be thinking that climate change isn’t an economic movement, but you will have a tough time reconciliing that with President Obama’s war on Coal and his statement that electricity rates will necessarily skyrocket under his plan. If Obama actually cared about the economically disadvantaged , he would not be engaged in such an endeavor as a war on coal, or petroleum, or natural gas.  In addition to hurting the poor, Obama’s policy has had the unpleasant side effect of further politicizing science.  Frederick Colbourne has written a guest post at the Ice-Age Now blog that puts the magnifying glass to this more recent Popular Delusion of  Climate Alarmism.

Climate Alarmism an Extraordinary Popular Delusion

by Frederick Colbourne

In my opinion, climate alarmism would be just another example of “Extraordinary Popular Delusions and the Madness of Crowds” rather than a ‘hustle’.  Except that climate alarmism is supported by governments that have aligned on the side of the promoters of the delusion and in so doing have politicized the science. State power is what makes climate alarmism a ‘hustle’, corrupting science in the process.Recently, the US lent its immense power to a global climate treaty intended to reverse global economic development by reducing access to cheap energy. The EU and Britain have signed on to promote and enforce what seems to me a cultish form of Luddism. While there have been Luddite movements since the early days of the Agricultural and Industrial Revolutions, these movements were never popular in America, until now.

The nostalgia for pristine Nature that inspired Thoreau’s Walden and now inspires an influential minority of Americans was not popular in the past, but has become a pillar of the modern cult and delusion. The cult of Nature as Mother Earth is about as remote from Earth science as it is possible to get, which probably accounts for the number of Hollywood celebrities who act as acolytes.  The root of the delusion is that Nature is benign. Three days in the wild without the products of agriculture and industry would convince most True Believers that Nature is hostile, when in reality, Nature is indifferent to Mankind. (Perhaps Thoreau was able…  Continue reading

Mantle Subsidence – backtracking from an article in The Daily Mail

trimble

I saw this article today In the UK’s The Daily Mail. Being a Geology buff, I decided to see what it was about. Knowing that some deride the Daily Mail as a not-credible Conservative tabloid, I decided to see for myself whether this story was overblown sensationalist tabloid fluff, or whether it had any merit on its own.

Anyone familiar with the geomorphology of the Southeastern United States, knows that the Appalachian Mountains are old eroded fold created mountains and that the area to the South and East of the Ohio River valley generally slopes towards sea-level with Florida being very flat and mostly only just meters or less above sea level.  This is indicative of a general subsidence, or lowering of land mass over millions of years. To be fair to the Mail, they did acknowledge this long time frame in the article. So the ‘big one’ is not going to happen tomorrow, it’s already been happening and for millions of years.

Underside of North American Plate Peeling Off- and sinking into Asthenosphere:

The source of the Daily Mail’s article backtracked to this article by Science Daily, posted May 3rd, 2016.  Lending credibility to the Mail’s article with it’s somewhat sensationalist headline “Giant Chunks of Earth’s Mantle Falling Off…”
“According to Biryol, pieces of the mantle have most likely been breaking off from underneath the plate since at least 65 million years ago. Because the researchers found fragments of hard rocks at shallow depths, this process is still ongoing and likely to continue into the future, potentially leading to more earthquakes in the region, he said.” Biryol is the lead researcher of the study:

C. Berk Biryol, Lara S. Wagner, Karen M. Fischer, Robert B. Hawman.Relationship Between Observed Upper Mantle Structures and Recent Tectonic Activity Across the Southeastern United States.Journal of Geophysical Research: Solid Earth, 2016; DOI:10.1002/2015JB012698

Also posted May 3rd at UNC Chapel Hill is this essentially same summation of the immediate above article.

Contemplating future maps of North America would only serve to confuse the issue, not only because of the great time scale involved with this kind of long term change, but because of countless other factors that would affect the design of such a map: Subsidence/Uplift, Ice accumulation/Ice melt, Erosion/Deposition,  the dynamics and changeability of tectonic plate motions.

But the idea of sections of the North American plate breaking off from below and thinning the area under the Southeastern states does explain how there came to be a few volcanoes in the vicinity of what is now Virginia:

“Instead, the team proposes that magma reached the surface as pieces of the thick crust beneath Virginia peeled away like sloughing skin — a process called delamination. Afterward, magma seeped through the newly thinned crust, reaching the surface through pre-existing cracks in the overlying rock. In this model, the Virginia lava is the chemical cousin of eastern Atlantic volcanoes, because their sources are both deeply buried leftovers from the breakup of Pangaea, the supercontinent. “– See more at: East Coast Youngest Volcanoes

And from the same live Science link immediately above:
The shedding crust under Virginia could underlie topographic changes in the Appalachians, such as their recent face-lift. The mountains are more rugged than they should be, given their age and the tectonic quiescence of the East Coast.

Another Big Win For The Environment

Nice to see some sanity prevail!

Real Science

I testified at my first Congressional hearing in support of wilderness almost 45 years ago. It was a very hot May day in Utah, and we had to push the van through sand dunes with the A/C turned off, to keep the engine from overheating.

Here is some good news. The communities of Churchover/Cotesbach near Rugby, England have just won a battle against the great environment wreckers who were trying to bribe landowners, using taxpayer money, to destroy the environment. I’m proud to have played a small part in that battle.

Congratulations to the Churchover/Cotesbach community who have finally won their battle against subsidised wind turbines in the Upper SwiftValley.

Looking Beyond the El Nino Hype

With the Sun continuing its descent into a Grand Minimum, we can expect global cooling to continue. El Nino is a manifestation of this cooling where warmer ocean waters give up their heat to the atmosphere. The wild swings in the jetstream(Meridional Flow pattern, as opposed to the more benign Zonal[W. to E.] flow) help to take that additional atmospheric warmth to the polar regions where the excess heat is more readily radiated away to outer space.

Meridional flow also leads to more extremes in weather patterns which is the direct opposite of the claims of the Global Warming/Climate Change alarmists. If it were my choice to make, I would take Global warming any day over global cooling, as it: 1. makes the planet as a whole more livable, 2. makes for better crop yields through, a) more dependable rainfall, and b) more vigorous plant growth via increased atmospheric CO2, and c) is characterized by the dominance of the jetstream’s Zonal flow component which lends itself to a reduced frequency of weather extremes.

The general cooling trend is expected to continue to around 2050 or longer and as a result, we can expect more droughts and floods, i.e.: a continued increase in weather extremes, more crop failures, more cows getting snowed over and freezing to death. And whatever any government entities decide we should do about dreaded ‘Climate Change’, it will have little to no effect on what mother nature has in store for us.
So, like the article says, don’t get too used to El Nino.
“Additionally, the Northern United States has more frequently observed brutally cold and snowy winters during La Niña events than El Niño ones.”

MICRO-CRITTERS RULE!

Another great post from Caleb. Brinicles!

Sunrise's Swansong

Sometimes, as my mind’s eye wanders over the Arctic Ocean, I am drawn ashore to contemplate wonders of the Tundra. I try to avoid politics, as the wonders are more wonderful when simply appreciated in the light of Truth, but Climate Alarmism is a sort of whirlpool that sucks you in, even when it is basically a comical shtick.

For example, along the coast of the Northwest Territories are the “Smoking Hills” of Franklin Bay, which appear over and over in Facebook images sent by sailors attempting the Northwest Passage. The sailors always seem jarred by the sight (and scent). Often they have been cluttering their log with editorial comments about how beautiful the arctic is, and what cads humans are to destroy the pristine beauty of nature with Global Warming caused by burning coal. Then they come across a stretch of coast that is in essence Mother Nature’s Strip…

An Example of Short Period Glacial Activity

Landslide at Mt. Steele

An avalanche/landslide has occurred at Mt. Steele, Yukon, CAN
http://earthobservatory.nasa.gov/IOTD/view.php?id=86826&eocn=home&eoci=iotd_title

here is another map of the area for comparison:
http://mapcarta.com/24511312

While most Glacial activity is at a slow snail-like pace, material transport, undercutting, and ice accumulation often leads to unstable slopes:

There was no earthquake or other obvious trigger for the avalanche. 
“Very large landslides like this often have very ambiguous triggers,”
said Stark. “Failure takes place because of a long-term accumulation 
of stress within the rock slope and a long-term weakening of the 
rock. A hair-trigger is often all that is needed.”
