LIFE/CULTURE
Buying Property in Spain?: If so, here's a must-read on the key ways to do this successfully.
Crossing The Road: I continue to be confused about what the law say about how drivers should respond to a flashing amber traffic light. I'd assumed that, when the pedestrian figure is red, the driver has the right of way, but not when it's green. The confusion arises because a good percentage of drivers stop for me when the light's on red. Especially if I'm standing on an island in the middle of the road. Even if I'm obviously reading a magazine or book and waiting for the light to change. But I'm not knocking this, of course.
Teaching English: Years ago, the PSOE President Zapatero (laughably) promised to bring 120,000 native English speakers to Spain, to improve the quality of teaching here. Yesterday, I learned that this policy had actually been put into practice, to some extent at least, and that Spain is now awash with auxiliares de conversación, who work 12 hours a week in public schools during the mornings and then try to teach privately later in the day. This probably explains why the hourly rate, here in Pontevedra at least, has been stuck at €15 an hour for at least 15 years. This being Spain, these assistants are now classified as students rather than employees, which means no social security payments have to be made in their regard. And there's some doubt about how qualified to teach they actually are. Just claiming to speak English might well be enough.
THE AGE WE LIVE IN
It's claimed that social media has brought us down to the post-truth age. And that, as with Russia's vast disinformation program, the aim is to disabuse us of the notion that there's any such thing as 'truth'. With the result that we believe no one. Not even the good people. Which will reap benefits for the baddies. If you're worried about this, here and here is BBC advice on how to check of the accuracy of social media reports. It might also be relevant for the so-called MSM.
AGW
I'm one of those who accepts there is global warming but - notwithstanding the scientific 'consensus' - wonders just how much is due to man and just how much we should be prepared to spend to do something about it. Especially as some say it's too late and spending vast amounts will only achieve very little. And particularly as the developing world will welch on its theoretical obligations. Reader David yesterday sent me the article at the end of the post. It's certainly thought-provoking.

ARTICLE
Former President Of
Greenpeace Scientifically Rips Climate Change To Shreds
TN Note: The following
is a lecture delivered by Patrick Moore, formerly President of
Greenpeace Int’l, to the Institution of Mechanical Engineers in
London. He is a vocal critic of faulty science that supports
climate-change caused by humans. Since he was a legend in the
eco-movement, his current assessment is credible and authoritative.
Should We Celebrate
Carbon Dioxide?
Thank you for the
opportunity to set out my views on climate change. As I have stated
publicly on many occasions, there is no definitive scientific proof,
through real-world observation, that carbon dioxide is responsible
for any of the slight warming of the global climate that has occurred
during the past 300 years, since the peak of the Little Ice Age. If
there were such a proof through testing and replication it would have
been written down for all to see.
The contention that
human emissions are now the dominant influence on climate is simply a
hypothesis, rather than a universally accepted scientific theory. It
is therefore correct, indeed verging on compulsory in the scientific
tradition, to be skeptical of those who express certainty that “the
science is settled” and “the debate is over”.
But there is certainty
beyond any doubt that CO2 is the building block for all life on Earth
and that without its presence in the global atmosphere at a
sufficient concentration this would be a dead planet. Yet today our
children and our publics are taught that CO2 is a toxic pollutant
that will destroy life and bring civilization to its knees. Tonight I
hope to turn this dangerous human-caused propaganda on its head.
Tonight I will demonstrate that human emissions of CO2 have already
saved life on our planet from a very untimely end. That in the
absence of our emitting some of the carbon back into the atmosphere
from whence it came in the first place, most or perhaps all life on
Earth would begin to die less than two million years from today.
But first a bit of
background.
I was born and raised
in the tiny floating village of Winter Harbour on the northwest tip
of Vancouver Island, in the rainforest by the Pacific. There was no
road to my village so for eight years myself and a few other children
were taken by boat each day to a one-room schoolhouse in the nearby
fishing village. I didn’t realize how lucky I was playing on the
tide flats by the salmon-spawning streams in the rainforest, until I
was sent off to boarding school in Vancouver where I excelled in
science. I did my undergraduate studies at the University of British
Columbia, gravitating to the life sciences – biology, biochemistry,
genetics, and forestry – the environment and the industry my family
has been in for more than 100 years. Then, before the word was known
to the general public, I discovered the science of ecology, the
science of how all living things are inter-related, and how we are
related to them. At the height of the Cold War, the Vietnam War, the
threat of all-out nuclear war and the newly emerging consciousness of
the environment I was transformed into a radical environmental
activist. While doing my PhD in ecology in 1971 I joined a group of
activists who had begun to meet in the basement of the Unitarian
Church, to plan a protest voyage against US hydrogen bomb testing in
Alaska.
We proved that a
somewhat rag-tag looking group of activists could sail an old fishing
boat across the north Pacific ocean and help change the course of
history. We created a focal point for the media to report on public
opposition to the tests.
When that H-bomb
exploded in November 1971, it was the last hydrogen bomb the United
States ever detonated. Even though there were four more tests planned
in the series, President Nixon canceled them due to the public
opposition we had helped to create. That was the birth of Greenpeace.
Flushed with victory,
on our way home from Alaska we were made brothers of the Namgis
Nation in their Big House at Alert Bay near my northern Vancouver
Island home. For Greenpeace this began the tradition of the Warriors
of the Rainbow, after a Cree Indian legend that predicted the coming
together of all races and creeds to save the Earth from destruction.
We named our ship the Rainbow Warrior and I spent the next fifteen
years in the top committee of Greenpeace, on the front lines of the
environmental movement as we evolved from that church basement into
the world’s largest environmental activist organization.
Next we took on French
atmospheric nuclear testing in the South Pacific. They proved a bit
more difficult than the US nuclear tests. It took years to eventually
drive these tests underground at Mururoa Atoll in French Polynesia.
In 1985, under direct orders from President Mitterrand, French
commandos bombed and sank the Rainbow Warrior in Auckland Harbour,
killing our photographer. Those protests continued until long after I
left Greenpeace. It wasn’t until the mid-1990s that nuclear testing
finally ended in the South Pacific, and it most other parts of the
world as well.
Going back to 1975,
Greenpeace set out to save the whales from extinction at the hands of
huge factory whaling fleets. We confronted the Soviet factory
whaling fleet in the North Pacific, putting ourselves in front of
their harpoons in our little rubber boats to protect the fleeing
whales. This was broadcast on television news around the world,
bringing the Save the Whales movement into everyone’s living rooms
for the first time. After four years of voyages, in 1979 factory
whaling was finally banned in the North Pacific, and by 1981 in all
the world’s oceans.
In 1978 I sat on a baby
seal off the East Coast of Canada to protect it from the hunter’s
club. I was arrested and hauled off to jail, the seal was clubbed and
skinned, but a photo of me being arrested while sitting on the baby
seal appeared in more than 3000 newspapers around the world the next
morning. We won the hearts and minds of millions of people who saw
the baby seal slaughter as outdated, cruel, and unnecessary.
Why then did I leave
Greenpeace after 15 years in the leadership? When Greenpeace began we
had a strong humanitarian orientation, to save civilization from
destruction by all-out nuclear war. Over the years the “peace” in
Greenpeace was gradually lost and my organization, along with much of
the environmental movement, drifted into a belief that humans are the
enemies of the earth. I believe in a humanitarian environmentalism
because we are part of nature, not separate from it. The first
principle of ecology is that we are all part of the same ecosystem,
as Barbara Ward put it, “One human family on spaceship Earth”,
and to preach otherwise teaches that the world would be better off
without us. As we shall see later in the presentation there is very
good reason to see humans as essential to the survival of life on
this planet.
In the mid 1980s I
found myself the only director of Greenpeace International with a
formal education in science. My fellow directors proposed a campaign
to “ban chlorine worldwide”, naming it “The Devil’s Element”.
I pointed out that chlorine is one of the elements in the Periodic
Table, one of the building blocks of the Universe and the 11th most
common element in the Earth’s crust. I argued the fact that
chlorine is the most important element for public health and
medicine. Adding chlorine to drinking water was the biggest advance
in the history of public health and the majority of our synthetic
medicines are based on chlorine chemistry. This fell on deaf ears,
and for me this was the final straw. I had to leave.
When I left Greenpeace
I vowed to develop an environmental policy that was based on science
and logic rather than sensationalism, misinformation, anti-humanism
and fear. In a classic example, a recent protest led by Greenpeace in
the Philippines used the skull and crossbones to associate Golden
Rice with death, when in fact Golden Rice has the potential to help
save 2 million children from death due to vitamin A deficiency every
year.
The Keeling curve of
CO2 concentration in the Earth’s atmosphere since 1959 is the
supposed smoking gun of catastrophic climate change. We presume CO2
was at 280 ppm at the beginning of the Industrial Revolution, before
human activity could have caused a significant impact. I accept that
most of the rise from 280 to 400 ppm is caused by human CO2 emissions
with the possibility that some of it is due to outgassing from
warming of the oceans.
NASA tells us that
“Carbon Dioxide Controls Earth’s Temperature” in child-like
denial of the many other factors involved in climate change. This is
reminiscent of NASA’s contention that there might be life on Mars.
Decades after it was demonstrated that there was no life on Mars,
NASA continues to use it as a hook to raise public funding for more
expeditions to the Red Planet. The promulgation of fear of Climate
Change now serves the same purpose. As Bob Dylan prophetically
pointed out, “Money doesn’t talk, it swears”, even in one of
the most admired science organizations in the world.
On the political front
the leaders of the G7 plan to “end extreme poverty and hunger” by
phasing out 85% of the world’s energy supply including 98% of the
energy used to transport people and goods, including food. The
Emperors of the world appear clothed in the photo taken at the close
of the meeting but it was obviously Photo-shopped. They should be
required to stand naked for making such a foolish statement.
The world’s top
climate body, the Intergovernmental Panel on Climate change, is
hopelessly conflicted by its makeup and it mandate. The Panel is
composed solely of the World Meteorological Organization, weather
forecasters, and the United Nations Environment Program,
environmentalists. Both these organizations are focused primarily on
short-term timescales, days to maybe a century or two. But the most
significant conflict is with the Panel’s mandate from the United
Nations. They are required only to focus on “a change of climate
which is attributed directly or indirectly to human activity that
alters the composition of the atmosphere, and which is in addition to
natural climate variability.”
So if the IPCC found that climate
change was not being affected by human alteration of the atmosphere
or that it is not “dangerous” there would be no need for them to
exist. They are virtually mandated to find on the side of apocalypse.
Scientific certainty,
political pandering, a hopelessly conflicted IPCC, and now the Pope,
spiritual leader of the Catholic Church, in a bold move to reinforce
the concept of original sin, says the Earth looks like “an immense
pile of filth” and we must go back to pre-industrial bliss, or is
that squalor?
And then there is the
actual immense pile of filth fed to us more than three times daily by
the green-media nexus, a seething cauldron of imminent doom, like we
are already condemned to Damnation in Hell and there is little chance
of Redemption. I fear for the end of the Enlightenment. I fear an
intellectual Gulag with Greenpeace as my prison guards.
Let’s begin with our
knowledge of the long-term history of the Earth’s temperature and
of CO2 in the Earth’s atmosphere. Our best inference from various
proxies back indicate that CO2 was higher for the first 4 billion
years of Earth’s history than it has been since the Cambrian Period
until today. I will focus on the past 540 million years since modern
life forms evolved. It is glaringly obvious that temperature and CO2
are in an inverse correlation at least as often as they are in any
semblance of correlation. Two clear examples of reverse correlation
occurred 150 million years and 50 million years ago. At the end of
the Jurassic temperature fell dramatically while CO2 spiked. During
the Eocene Thermal Maximum, temperature was likely higher than any
time in the past 550 million years while CO2 had been on a downward
track for 100 million years. This evidence alone sufficient to
warrant deep speculation of any claimed lock-step causal relationship
between CO2 and temperature.
The Devonian Period
beginning 400 million years ago marked the culmination of the
invasion of life onto the land. Plants evolved to produce lignin,
which in combination with cellulose, created wood which in turn for
the first time allowed plants to grow tall, in competition with each
other for sunlight. As vast forests spread across the land living
biomass increased by orders of magnitude, pulling down carbon as CO2
from the atmosphere to make wood. Lignin is very difficult to break
down and no decomposer species possessed the enzymes to digest it.
Trees died atop one another until they were 100 metres or more in
depth. This was the making of the great coal beds around the world as
this huge store of sequestered carbon continued to build for 90
million years. Then, fortunately for the future of life, white rot
fungi evolved to produce the enzymes that can digest lignin and
coincident with that the coal-making era came to an end.
There was no guarantee
that fungi or any other decomposer species would develop the complex
of enzymes required to digest lignin. If they had not, CO2, which had
already been drawn down for the first time in Earth’s history to
levels similar to todays, would have continued to decline as trees
continued to grow and die. That is until CO2 approached the threshold
of 150 ppm below which plants begin first to starve, then stop
growing altogether, and then die. Not just woody plants but all
plants. This would bring about the extinction of most, if not all,
terrestrial species, as animals, insects, and other invertebrates
starved for lack of food. And that would be that. The human species
would never have existed. This was only the first time that there was
a distinct possibility that life would come close to extinguishing
itself, due to a shortage of CO2, which is essential for life on
Earth.
A well-documented
record of global temperature over the past 65 million years shows
that we have been in a major cooling period since the Eocene Thermal
Maximum 50 million years ago. The Earth was an average 16C warmer
then, with most of the increased warmth at the higher latitudes. The
entire planet, including the Arctic and Antarctica were ice-free and
the land there was covered in forest. The ancestors of every species
on Earth today survived through what may have been the warmest time
in the history of life. It makes one wonder about dire predictions
that even a 2C rise in temperature from pre-industrial times would
cause mass extinctions and the destruction of civilization. Glaciers
began to form in Antarctica 30 million years ago and in the northern
hemisphere 3 million years ago. Today, even in this interglacial
period of the Pleistocene Ice Age, we are experiencing one of the
coldest climates in the Earth’s history.
Coming closer to the
present we have learned from Antarctic ice cores that for the past
800,000 years there have been regular periods of major glaciation
followed by interglacial periods in 100,000 year-cycles. These cycles
coincide with the Milankovitch cycles that are tied to the
eccentricity of the Earth’s orbit and its axial tilt. It is highly
plausible that these cycles are related to solar intensity and the
seasonal distribution of solar heat on the Earth’s surface. There
is a strong correlation between temperature and the level of
atmospheric CO2 during these successive glaciations, indicating a
possible cause-effect relationship between the two. CO2 lags
temperature by an average of 800 years during the most recent
400,000-year period, indicating that temperature is the cause, as the
cause never comes after the effect.
Looking at the past
50,000 years of temperature and CO2 we can see that changes in CO2
follow changes in temperature. This is as one could expect, as the
Milankovitch cycles are far more likely to cause a change in
temperature than a change in CO2. And a change in the temperature is
far more likely to cause a change in CO2 due to outgassing of CO2
from the oceans during warmer times and an ingassing (absorption) of
CO2 during colder periods. Yet climate alarmists persist in insisting
that CO2 is causing the change in temperature, despite the illogical
nature of that assertion.
It is sobering to
consider the magnitude of climate change during the past 20,000
years, since the peak of the last major glaciation. At that time
there were 3.3 kilometres of ice on top of what is today the city of
Montreal, a city of more than 3 million people. 95% of Canada was
covered in a sheet of ice. Even as far south as Chicago there was
nearly a kilometre of ice. If the Milankovitch cycle continues to
prevail, and there is little reason aside from our CO2 emissions to
think otherwise, this will happen gradually again during the next
80,000 years. Will our CO2 emissions stave off another glaciation as
James Lovelock has suggested? There doesn’t seem to be much hope of
that so far, as despite 1/3 of all our CO2 emissions being released
during the past 18 years the UK Met Office contends there has been no
statistically significant warming during this century.
At the height of the
last glaciation the sea level was about 120 metres lower than it is
today. By 7,000 years ago all the low-altitude, mid-latitude glaciers
had melted. There is no consensus about the variation in sea level
since then although many scientists have concluded that the sea level
was higher than today during the Holocene Thermal optimum from 9,000
to 5,000 years ago when the Sahara was green. The sea level may also
have been higher than today during the Medieval Warm Period.
Hundred of islands near
the Equator in Papua, Indonesia, have been undercut by the sea in a
manner that gives credence to the hypothesis that there has been
little net change in sea level in the past thousands of years. It
takes a long time for so much erosion to occur from gentle wave
action in a tropical sea.
Coming back to the
relationship between temperature and CO2 in the modern era we can see
that temperature has risen at a steady slow rate in Central England
since 1700 while human CO2 emissions were not relevant until 1850 and
then began an exponential rise after 1950. This is not indicative of
a direct causal relationship between the two. After freezing over
regularly during the Little Ice Age the River Thames froze for the
last time in 1814, as the Earth moved into what might be called the
Modern Warm Period.
The IPCC states it is
“extremely likely” that human emissions have been the dominant
cause of global warming “since the mid-20th century”, that is
since 1950. They claim that “extremely” means 95% certain, even
though the number 95 was simply plucked from the air like an act of
magic. And “likely” is not a scientific word but rather
indicative of a judgment, another word for an opinion.
There was a 30-year
period of warming from 1910-1940, then a cooling from 1940 to 1970,
just as CO2 emissions began to rise exponentially, and then a 30-year
warming from 1970-2000 that was very similar in duration and
temperature rise to the rise from 1910-1940. One may then ask “what
caused the increase in temperature from 1910-1940 if it was not human
emissions? And if it was natural factors how do we know that the same
natural factors were not responsible for the rise between 1970-2000.”
You don’t need to go back millions of years to find the logical
fallacy in the IPCC’s certainty that we are the villains in the
piece.
Water is by far the
most important greenhouse gas, and is the only molecule that is
present in the atmosphere in all three states, gas, liquid, and
solid. As a gas, water vapour is a greenhouse gas, but as a liquid
and solid it is not. As a liquid water forms clouds, which send solar
radiation back into space during the day and hold heat in at night.
There is no possibility that computer models can predict the net
effect of atmospheric water in a higher CO2 atmosphere. Yet warmists
postulate that higher CO2 will result in positive feedback from
water, thus magnifying the effect of CO2 alone by 2-3 times. Other
scientists believe that water may have a neutral or negative feedback
on CO2. The observational evidence from the early years of this
century tends to reinforce the latter hypothesis.
How many politicians or
members of the media or the public are aware of this statement about
climate change from the IPCC in 2007?
“we should recognise
that we are dealing with a coupled nonlinear chaotic system, and
therefore that the long-term prediction of future climate states is
not possible.”
There is a graph
showing that the climate models have grossly exaggerated the rate of
warming that confirms the IPCC statement. The only trends the
computer models seem able to predict accurately are ones that have
already occurred.
Coming to the core of
my presentation, CO2 is the currency of life and the most important
building block for all life on Earth. All life is carbon-based,
including our own. Surely the carbon cycle and its central role in
the creation of life should be taught to our children rather than the
demonization of CO2, that “carbon” is a “pollutant” that
threatens the continuation of life. We know for a fact that CO2 is
essential for life and that it must be at a certain level in the
atmosphere for the survival of plants, which are the primary food for
all the other species alive today. Should we not encourage our
citizens, students, teachers, politicians, scientists, and other
leaders to celebrate CO2 as the giver of life that it is?
It is a proven fact
that plants, including trees and all our food crops, are capable of
growing much faster at higher levels of CO2 than present in the
atmosphere today. Even at the today’s concentration of 400 ppm
plants are relatively starved for nutrition. The optimum level of CO2
for plant growth is about 5 times higher, 2000 ppm, yet the alarmists
warn it is already too high. They must be challenged every day by
every person who knows the truth in this matter. CO2 is the giver of
life and we should celebrate CO2 rather than denigrate it as is the
fashion today.
We are witnessing the
“Greening of the Earth” as higher levels of CO2, due to human
emissions from the use of fossil fuels, promote increased growth of
plants around the world. This has been confirmed by scientists with
CSIRO in Australia, in Germany, and in North America. Only half of
the CO2 we are emitting from the use of fossil fuels is showing up in
the atmosphere. The balance is going somewhere else and the best
science says most of it is going into an increase in global plant
biomass. And what could be wrong with that, as forests and
agricultural crops become more productive?
All the CO2 in the
atmosphere has been created by outgassing from the Earth’s core
during massive volcanic eruptions. This was much more prevalent in
the early history of the Earth when the core was hotter than it is
today. During the past 150 million years there has not been enough
addition of CO2 to the atmosphere to offset the gradual losses due to
burial in sediments.
Let’s look at where
all the carbon is in the world, and how it is moving around.
Today, at just over 400
ppm, there are 850 billion tons of carbon as CO2 in the atmosphere.
By comparison, when modern life-forms evolved over 500 million years
ago there was nearly 15,000 billion tons of carbon in the atmosphere,
17 times today’s level. Plants and soils combined contain more than
2,000 billion tons of carbon, more that twice as much as the entire
global atmosphere. The oceans contain 38,000 billion tons of carbon,
as dissolved CO2, 45 times as much as in the atmosphere. Fossil
fuels, which are made from plants that pulled CO2 from the atmosphere
account for 5,000 – 10,000 billion tons of carbon, 6 – 12 times
as much carbon as is in the atmosphere.
But the truly stunning
number is the amount of carbon that has been sequestered from the
atmosphere and turned into carbonaceous rocks. 100,000,000 billion
tons, that’s one quadrillion tons of carbon, have been turned into
stone by marine species that learned to make armour-plating for
themselves by combining calcium and carbon into calcium carbonate.
Limestone, chalk, and marble are all of life origin and amount to
99.9% of all the carbon ever present in the global atmosphere. The
white cliffs of Dover are made of the calcium carbonate skeletons of
coccolithophores, tiny marine phytoplankton.
The vast majority of
the carbon dioxide that originated in the atmosphere has been
sequestered and stored quite permanently in carbonaceous rocks where
it cannot be used as food by plants.
Beginning 540 million
years ago at the beginning of the Cambrian Period many marine species
of invertebrates evolved the ability to control calcification and to
build armour plating to protect their soft bodies. Shellfish such as
clams and snails, corals, coccolithofores (phytoplankton) and
foraminifera (zooplankton) began to combine carbon dioxide with
calcium and thus to remove carbon from the life cycle as the shells
sank into sediments; 100,000,000 billion tons of carbonaceous
sediment. It is ironic that life itself, by devising a protective
suit of armour, determined its own eventual demise by continuously
removing CO2 from the atmosphere. This is carbon sequestration and
storage writ large. These are the carbonaceous sediments that form
the shale deposits from which we are fracking gas and oil today. And
I add my support to those who say, “OK UK, get fracking”.
The past 150 million
years has seen a steady drawing down of CO2 from the atmosphere.
There are many components to this but what matters is the net effect,
a removal on average of 37,000 tons of carbon from the atmosphere
every year for 150 million years. The amount of CO2 in the atmosphere
was reduced by about 90% during this period. This means that volcanic
emissions of CO2 have been outweighed by the loss of carbon to
calcium carbonate sediments on a multi-million year basis.
If this trend continues
CO2 will inevitably fall to levels that threaten the survival of
plants, which require a minimum of 150 ppm to survive. If plants die
all the animals, insects, and other invertebrates that depend on
plants for their survival will also die.
How long will it be at
the present level of CO2 depletion until most or all of life on Earth
is threatened with extinction by lack of CO2 in the atmosphere?
During this Pleistocene
Ice Age, CO2 tends to reach a minimum level when the successive
glaciations reach their peak. During the last glaciation, which
peaked 18,000 years ago, CO2 bottomed out at 180 ppm, extremely
likely the lowest level CO2 has been in the history of the Earth.
This is only 30 ppm above the level that plants begin to die.
Paleontological research has demonstrated that even at 180 ppm there
was a severe restriction of growth as plants began to starve. With
the onset of the warmer interglacial period CO2 rebounded to 280
ppm. But even today, with human emissions causing CO2 to reach
400 ppm plants are still restricted in their growth rate, which would
be much higher if CO2 were at 1000-2000 ppm.
Here is the shocking
news. If humans had not begun to unlock some of the carbon stored as
fossil fuels, all of which had been in the atmosphere as CO2 before
sequestration by plants and animals, life on Earth would have soon
been starved of this essential nutrient and would begin to die. Given
the present trends of glaciations and interglacial periods this would
likely have occurred less than 2 million years from today, a blink in
nature’s eye, 0.05% of the 3.5 billion-year history of life.
No other species could
have accomplished the task of putting some of the carbon back into
the atmosphere that was taken out and locked in the Earth’s crust
by plants and animals over the millennia. This is why I honour James
Lovelock in my lecture this evening. Jim was for many years of the
belief that humans are the one-and-only rogue species on Gaia,
destined to cause catastrophic global warming. I enjoy the Gaia
hypothesis but I am not religious about it and for me this was too
much like original sin. It was as if humans were the only evil
species on the Earth.
But James Lovelock has
seen the light and realized that humans may be part of Gaia’s plan,
and he has good reason to do so. And I honour him because it takes
courage to change your mind after investing so much of your
reputation on the opposite opinion. Rather than seeing humans as the
enemies of Gaia, Lovelock now sees that we may be working with Gaia
to “stave of another ice age”, or major glaciation. This is much
more plausible than the climate doom-and gloom scenario because our
release of CO2 back into the atmosphere has definitely reversed the
steady downward slide of this essential food for life, and hopefully
may reduce the chance that the climate will slide into another period
of major glaciation. We can be certain that higher levels of CO2 will
result in increased plant growth and biomass. We really don’t know
whether or not higher levels of CO2 will prevent or reduce the
eventual slide into another major glaciation. Personally I am not
hopeful for this because the long-term history just doesn’t support
a strong correlation between CO2 and temperature.
It does boggle the mind
in the face of our knowledge that the level of CO2 has been steadily
falling that human CO2 emissions are not universally acclaimed as a
miracle of salvation. From direct observation we already know that
the extreme predictions of CO2’s impact on global temperature are
highly unlikely given that about one-third of all our CO2 emissions
have been discharged during the past 18 years and there has been no
statistically significant warming. And even if there were some
additional warming that would surely be preferable to the
extermination of all or most species on the planet.
You heard it here.
“Human emissions of carbon dioxide have saved life on Earth from
inevitable starvation and extinction due to lack of CO2”. To use
the analogy of the Atomic Clock, if the Earth were 24 hours old we
were at 38 seconds to midnight when we reversed the trend towards the
End Times. If that isn’t good news I don’t know what is. You
don’t get to stave off Armageddon every day.
I issue a challenge to
anyone to provide a compelling argument that counters my analysis of
the historical record and the prediction of CO2 starvation based on
the 150 million year trend. Ad hominem arguments about “deniers”
need not apply. I submit that much of society has been collectively
misled into believing that global CO2 and temperature are too high
when the opposite is true for both. Does anyone deny that below 150
ppm CO2 that plants will die? Does anyone deny that the Earth has
been in a 50 million-year cooling period and that this Pleistocene
Ice Age is one of the coldest periods in the history of the planet?
If we assume human
emissions have to date added some 200 billion tons of CO2 to the
atmosphere, even if we ceased using fossil fuels today we have
already bought another 5 million years for life on earth. But we will
not stop using fossil fuels to power our civilization so it is likely
that we can forestall plant starvation for lack of CO2 by at least 65
million years. Even when the fossil fuels have become scarce we have
the quadrillion tons of carbon in carbonaceous rocks, which we can
transform into lime and CO2 for the manufacture of cement. And we
already know how to do that with solar energy or nuclear energy. This
alone, regardless of fossil fuel consumption, will more than offset
the loss of CO2 due to calcium carbonate burial in marine sediments.
Without a doubt the human species has made it possible to prolong the
survival of life on Earth for more than 100 million years. We are not
the enemy of nature but its salvation.
As a postscript I would
like to make a few comments about the other side of the alleged
dangerous climate change coin, our energy policy, in particular the
much maligned fossil fuels; coal, oil, and natural gas.
Depending how it’s
tallied, fossil fuels account for between 85-88% of global energy
consumption and more than 95% of energy for the transport of people
and goods, including our food.
Earlier this year the
leaders of the G7 countries agreed that fossil fuels should be phased
out by 2100, a most bizarre development to say the least. Of course
no intelligent person really believes this will happen but it is a
testament to the power of the elites that have converged around the
catastrophic human-caused climate change that so many alleged world
leaders must participate in the charade. How might we convince them
to celebrate CO2 rather than to denigrate it?
A lot of nasty things
are said about fossil fuels even though they are largely responsible
for our longevity, our prosperity, and our comfortable lifestyles.
Hydrocarbons, the
energy components of fossil fuels, are 100% organic, as in organic
chemistry. They were produced by solar energy in ancient seas and
forests. When they are burned for energy the main products are water
and CO2, the two most essential foods for life. And fossil fuels are
by far the largest storage battery of direct solar energy on Earth.
Nothing else comes close except nuclear fuel, which is also solar in
the sense that it was produced in dying stars.
Today, Greenpeace
protests Russian and American oil rigs with 3000 HP diesel-powered
ships and uses 200 HP outboard motors to board the rigs and hang
anti-oil plastic banners made with fossil fuels. Then they issue a
media release telling us we must “end our addiction to oil”. I
wouldn’t mind so much if Greenpeace rode bicycles to their sailing
ships and rowed their little boats into the rigs to hang organic
cotton banners. We didn’t have an H-bomb on board the boat that
sailed on the first Greenpeace campaign against nuclear testing.
Some of the world’s
oil comes from my native country in the Canadian oil sands of
northern Alberta. I had never worked with fossil fuel interests until
I became incensed with the lies being spread about my country’s oil
production in the capitals of our allies around the world. I visited
the oil sands operations to find out for myself what was happening
there.
It is true it’s not a
pretty sight when the land is stripped bare to get at the sand so the
oil can be removed from it. Canada is actually cleaning up the
biggest natural oil spill in history, and making a profit from it.
The oil was brought to the surface when the Rocky Mountains were
thrust up by the colliding Pacific Plate. When the sand is returned
back to the land 99% of the so-called “toxic oil” has been
removed from it.
Anti-oil activists say
the oil-sands operations are destroying the boreal forest of Canada.
Canada’s boreal forest accounts for 10% of all the world’s
forests and the oil-sands area is like a pimple on an elephant by
comparison. By law, every square inch of land disturbed by oil-sands
extraction must be returned to native boreal forest. When will cities
like London, Brussels, and New York that have laid waste to the
natural environment be returned to their native ecosystems?
The art and science of
ecological restoration, or reclamation as it is called in the mining
industry, is a well-established practice. The land is re-contoured,
the original soil is put back, and native species of plants and trees
are established. It is possible, by creating depressions where the
land was flat, to increase biodiversity by making ponds and lakes
where wetland plants, insects, and waterfowl can become established
in the reclaimed landscape.
The tailings ponds
where the cleaned sand is returned look ugly for a few years but are
eventually reclaimed into grasslands. The Fort McKay First Nation is
under contract to manage a herd of bison on a reclaimed tailings
pond. Every tailings pond will be reclaimed in a similar manner when
operations have been completed.
As an ecologist and
environmentalist for more than 45 years this is good enough for me.
The land is disturbed for a blink of an eye in geological time and is
then returned to a sustainable boreal forest ecosystem with cleaner
sand. And as a bonus we get the fuel to power our weed-eaters,
scooters, motorcycles, cars, trucks, buses, trains, and aircraft.
To conclude, carbon
dioxide from burning fossil fuels is the stuff of life, the staff of
life, the currency of life, indeed the backbone of life on Earth.
I hope you have seen
CO2 from a new perspective and will join with me to Celebrate CO2!
