Should We Celebrate Carbon Dioxide?

My Lords and Ladies, Ladies and Gentlemen:

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 ‚Äì biology, biochemistry, genetics, and forestry ‚Äì 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 Ph.D. 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 are 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 Photoshopped. 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 its 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.”‚Ä®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 the 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 indicates 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, the 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 today’s, 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 in-gassing (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.
