Of course we should. This item nicely addresses our pertinent geological history over the past several millions of years.
Patrick Moore deftly attacks the scientific illiteracy of our so called radical eco movement types which is better described as eco ignorance.
He is a trained scientist while the movement itself has clearly been hijacked simple activists lacking any scientific credentials.
Patrick Moore: 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 am honoured to have been chosen to deliver your annual lecture.
Thank you for listening to me this evening.
