Medieval Warming Period Cools Climate Change Alarmism
Posted 03/27/2012 06:58 PM ET
Environment: Climate change alarmists
either ignore the existence of the Medieval Warm Period or say that it
was regional rather than global. A new report, however, shows that the
warming was worldwide.
The Medieval Warm Period is a profound problem for those who claim
that man's 20th- and 21st-century carbon dioxide emissions are warming
the earth.
If an era as warm or warmer than today did indeed exist 500 to 1,000
years ago, before man had invented the CO2-emitting internal combustion
engine, then it weakens their claim that any warming occurring now is
due to human activity. The reality of such a period is a strong sign
that climate change is both natural and cyclical, not moved by man's
modern habits.
In fact, confirmation of the Medieval Warm Period not only dilutes the alarmists' argument, it virtually kills it. [The Minoan and Roman Warm Periods also do their share!]
So rather than deal with it, they act as if it never happened. They
want to try to make it, as one message among the Climate-gate emails
suggested, "go away."
Or they insist that it was confined to Europe and maybe North
America, and therefore is of little relevance. This is the position of
the United Nations' Intergovernmental Panel on Climate Change, which is
supported by America's Environmental Protection Agency that says the
"geographical extent, magnitude and timing of the warmth during this
period is uncertain." [That is an out-and-out
lie. Not only have a number of studies since the year 2000 shown that
the Medieval Warm Period was global in extent (in addition to the one that is the subject of this editorial), they are absolutely
certain that the magnitude was such that Greenland was "green" and that
the Vikings settled and farmed areas there that are just now being
uncovered by receding glaciers, while the waters of northern Canada were so ice-free in the summers that explorers searched for the "fabled" Northwest Passage!]
It's also the position of Al Gore, the former vice president who set off most of the global warming hysteria.
He has maligned the Medieval Warm Period as a "tiny" blip on the
temperature chart of history that he imagines proves the nonsense that
he's been disgorging for years.[Al Gore is an
idiot who got Cs and Ds in Science classes and flunked out of Vanderbilt
Divinity, and yet there are people who actually believe the cretin?]
Scientists
from Syracuse University, however, have found evidence that strongly
affirms that the Medieval Warm Period was no myth but rather a global
event, affecting even Antarctica.
Their study, published in the April issue of Earth and Planetary
Science Letters, carries the academic title of "An Ikaite record of late
Holocene climate at the Antarctic Peninsula."
Journalists shouldn't let the wonkish title stop them from reporting on the study. And they probably won't.
Instead, the bulk of the mainstream media will conveniently miss the
study for another reason: It doesn't fit their
man-is-causing-the-earth-to-warm narrative.
There's nothing new there, though.
It's an old habit for the media to either ignore or poorly cover evidence that doesn't support global warming alarmism.[They can't help themselves - the great majority of the media are, after all, liberal Democrats!]
A rather cursory look at just three websites — former meteorologist
Anthony Watts' blog, junkscience.com and the home of the Science and
Environmental Policy Project — reveals the media have passed on at
least 25 studies, reports and articles that punch holes in the global
warming claim.
From a study that found tree-ring data, used extensively in the
hockey stick chart that allegedly proves global warming, are an
unreliable proxy of past temperatures; to an account of growing sea ice
in the Arctic and in Antarctica; to a report about researchers finding a
new ocean current, there is a lot of contrary evidence to disclose.
And that's looking back only a month. How much more evidence is out
there contradicting the scientific "consensus" that man is warming his
planet, but is being disregarded by an agenda-driven mainstream media?
Don't expect the media-enviro-alarmist complex to give up its
campaign because research has yet again shown that its case against
humanity continues to wilt under scrutiny.
It's too heavily invested in its story and the goal — stronger
government, weaker capitalism and diminished liberty — that it's been
zealously working toward.
But it has suffered another small cut, and the minor wounds keep
adding up as the facts continue to roll out and the effects of climate
change that we have been warned about never develop. Its golden age will
have been pushed closer to its conclusion by a warm period.
In addition to the Medieval Warm Period there have been two other
periods over the past 5,000 years when earth was as warm, or warmer,
than the late 20th century, the Minoan and Roman Warm Periods. AGW
alarmists totally ignore them because there was no "man-made" CO2 to
blame the warming on - only natural climate cycles! And yet the Obama
EPA just issued a ruling that will require future generating plants to
reduce their emissions of CO2, considered by the EPA to be a "greenhouse
gas," a ruling which will make it uneconomical to build new coal-fired
plants, thus wasting one of our most abundant energy sources!























Previous natural climate changes *prove* that our influence on the climate, which is now very large, is going to cause massive global warming and all the associated chaos of drought, storms, floods, heatwaves and so on.
Soils annually contribute between 76.5 & 80.4 gigatons of carbon to the atmosphere (Raich & Potter, 1995; Raich et al., 2002), dwarfing the 7.823 gigatons of carbon emission attributed to the combustion of fossil fuels (IPCC, 2007). According to Schlesinger (1991), the carbon reservoir represented by photosynthesising biota is around 560 gigatons. Deforestation to the tune of 156 gigatons since 1850 (Haughton & Hackler, 2002) represents a total deforestation of 22%. Although current photosynthesising biota account for 120 gigatons of atmospheric carbon sequestration (Bowes, 1991), this figure would be closer to 154 gigatons of carbon sequ...

Although current photosynthesising biota account for 120 gigatons of atmospheric carbon sequestration (Bowes, 1991), this figure would be closer to 154 gigatons of carbon sequestration back in 1850 given the impact of deforestation on photosynthesizing biota. The total accumulated loss of atmospheric carbon sequestration since 1850 is currently more than 38 gigatons (Casey, 2008); greater than four times the amount of carbon released by fossil fuel combustion to the atmosphere.
In other words, man-made CO2 is within the 'statistical noise' of naturally occurring CO2 in the atmosphere, as the statistics I quoted above (from the IPCC, by the way!) don't include outgassing from the oceans, which is one of the largest contributors to atmospheric CO2! Inasmuch as Earth has been warming out of the Little Ice Age and "Dickens Winters" since the mid-19th century, and inasmuch as warmer water cannot hold as much CO2 as cold water (check your warm beer for this factoid!), outgassing from the oceans has been on the increase!
Carbon dioxide is produced by many natural sources including volcanoes, animals, and plants when aspiring at night. Carbon dioxide has been as high as 7000ppm and back in the Devonian, corals evolved when carbon dioxide levels were more than seven times the present concentration. Forests first appeared in force during the Carboniferous when carbon dioxide levels were at least 1000ppm. The horticultural benefits of high carbon dioxide levels are well known (Sylvan, 1992). In fact, it has been widely and repeatedly found both through historical (IE tree ring studies of year to year growth) and experimental studies of plant growth with reference to annual atmospheric carbon dioxide concentrations, that higher carbon dioxide levels lead to much greater plant growth (eg. Kimball, 1983; Cure & Acock, 1986; Mortensen, 1987, Lawler & Mitchell, 1991; Drake & Leadley, 1991; Gifford, 1992; Poorter, 1993, Kimball et al., 2007).
In fact, both terrestrial (McNaughton, 1989) and aquatic (Cyr & Face, 1993) animal life have prospered due to increased plant growth resulting from rising carbon dioxide levels, proving that of all industrial emissions, carbon dioxide is not a pollutant but is in f...

Carbon dioxide is produced by many natural sources including volcanoes, animals, and plants when aspiring at night. Carbon dioxide has been as high as 7000ppm and back in the Devonian, corals evolved when carbon dioxide levels were more than seven times the present concentration. Forests first appeared in force during the Carboniferous when carbon dioxide levels were at least 1000ppm. The horticultural benefits of high carbon dioxide levels are well known (Sylvan, 1992).

In fact, both terrestrial (McNaughton, 1989) and aquatic (Cyr & Face, 1993) animal life have prospered due to increased plant growth resulting from rising carbon dioxide levels, proving that of all industrial emissions, carbon dioxide is not a pollutant but is in fact a natural aerial fertiliser. The fact that carbon pooling as a result of plant growth, accelerates in response to rising carbon dioxide levels strongly suggests that currently increasing carbon dioxide levels have more to do with loss of photosynthesising carbon sinks than existing sources of atmospheric carbon such as fossil fuel combustion.
Soils annually contribute between 76.5 & 80.4 gigatons of carbon to the atmosphere (Raich & Potter, 1995; Raich et al., 2002),dwarfing the 7.823 gigatons of carbon emission attributed to the combustion of fossil fuels (IPCC, 2007). The IPCC's figure of 2.38 gigatons of annual carbon emission to the atmosphere from deforestation roughly corresponds to results from the studies of Melillo et al. (1996) and Haughton & Hackler (2002). As we shall see, it is the balance of much larger sources and sinks of carbon dioxide that will play the greatest role in determining atmospheric carbon dioxide levels.
While the origin of much of the modern atmospheric carbon dioxide is speculated to be industrial, carbon dioxide levels vary substantially on a seasonal basis and correlate inversely with smaller seasonal variations in atmospheric oxygen concentrations (Keeling et al., 1996). However, the relationship between atmospheric carbon dioxide and oxygen concentration curves reflects decreasing photosynthesis, which Lyons (2007) documents as the almost exclusive producer of oxygen.
While we are busily distracted with the assumption that fossil fuel combustion is the main cause of the rise observed in atmospheric carbon dioxide, we forget to consider the role of decreasing photosynthesis consequent to deforestation. According to Schlesinger (1991), the carbon reservoir represented by photosynthesising biota is around 560 gigatons. Deforestation to the tune of 156 gigatons since 1850 (Haughton & Hackler, 2002) represents a total deforestation of 22%. Although current photosynthesising biota account for 120 gigatons of atmospheric carbon sequestration (Bowes, 1991), this figure would be closer to 154 gigatons of carbon sequestration back in 1850 given the impact of deforestation on photosynthesizing biota.
The total accumulated loss of atmospheric carbon sequestration since 1850 is currently more than 38 gigatons (Casey, 2008); greater than four times the amount of carbon released by fossil fuel combustion to the atmosphere. The dominant human activity contributing to the rise of atmospheric carbon dioxide is not fossil fuel combustion but the deficit in photosynthesis accumulated over more than 150 years of deforestation.
Ice core data shows that atmospheric CO₂ was stable at around 280 ±5 ppm for the last 10,000 years. In the last 250 years it has suddenly shot up to 390ppm.
However, if *all* of the 1.2 trillion tons of CO₂ we've emitted since the start of the Industrial Revolution was still in the atmosphere, it would be at 440ppm (because 1ppm of CO₂ is 7.82 billion tons).
The difference of ~50 ppm has been absorbed by the natural world - i.e. nature so far has been a net absorber of CO₂, not an emitter.
In other words, none of the net increase in atmospheric CO₂ can *possibly* come from natural sources.
Water vapor accounts for approximately 95% of the total “greenhouse effect” of our atmosphere. CO2 and other gases account for the remaining 5%. “Natural sources,” e.g. outgassing of CO2 from the oceans, and CO2 from vegetation, account for ~ 150 gigatons of CO2 per year, while the burning of fossil fuels (“man-made CO2") accounts for ~ 5 gigatons per year. So man’s contribution to the total greenhouse effect of all atmospheric CO2 is ~ 3.22% [5/155 X 100], which in turn accounts for < 5% of the total greenhouse effect (after subtracting methane and other gases in the atmosphere). This leaves us with a total contribution by man-made CO2 to the greenhouse effect of less than.1611%! Note that these figures are taken from IPCC data!
This means that, according to the IPCC’s own data, the total contribution of man-made CO2 to the greenhouse effect is less than 2/10ths of one percent (.20%) of the total effect!

"In other words, none of the net increase in atmospheric CO₂ can *possibly* come from natural sources. Wrong! Earth has been warming out of the Little Ice Age and Maunder Minimum since the mid-19th century - as the oceans warm CO2 becomes less soluble in water and "outgasses," increasing the concentration in the atmosphere.
"In other words, none of the net increase in atmospheric CO₂ can *possibly* come from natural sources."
You don't think that increase might just coincide with earth's warming out of the Little Ice Age and Maunder Minimum over that 250 year period, with the oceans warming and outgassing CO2?

We need all thee CO2 to help our forests grow nice big trees.
Trees the finest renewable resource in the world.
Just remember they give us back as they grow that wonderful stuff called oxygen.
We have a huge battle ahead with "the greater good" being claimed superior to our Right to Life. We are Ruled by a fella who apparently has no birth certificate. We are $16 trillion in debt. That's real, and matters much more.
Gore flunked out of divinity school and the libs listen to him?
