Once again, following the “Peace in our time” success of Paris three years ago, “Climate Change” has been adopted as the theme for this year’s global bureaucratic Christmas party with Poland, of all places, the host.
Never mind the carbon footprint of the twenty thousand plus people who travelled from all over the globe to have a ‘conversation about climate change”. Never mind the irony that it was being held in the heartland of Europe’s largest coal-producing region. The important thing is who hosted the best party of the week?
Once again we are told that the high priests had a resoundingly successful conference as the chairman was able to announce at the Grand Galah dinner that sacrifices have been made and the gods of the climate have been appeased. A signed charter will save the planet from global warming. As if we had not heard that all before. Those who believe climate change is a process of nature, including the most powerful people in the most industrialised countries, just ignore them; the hand wringers say it is far too little, far too late, we are all going to fry.
Here’s an interesting climate change fact: The study of the chemical structure of polar ice cores, sea bed sediment and fossilised planet matter tells our scientists that C02 levels have absolutely zero correlation with temperature. I have no idea how the alarmists managed to convince everyone that our C02 levels are causing our climate change, but the climate scientists own published research tracking the earth’s climate over hundreds of millions of years show conclusively that C02 change has no connection with temperature change.
As you can see, (click image to enlarge) the earth itself, and life on it, have survived both temperature and C02 levels significantly higher than anything we are currently experiencing. The temperature has only been as low as it is now at the coldest point of three of the previous four ice ages.
C02 levels at the beginning of the chart (600+ million years ago) were seriously high. They dropped and bounced around for two hundred million years before coming right down and then again the levels bounced around quite a bit for another 360 million years before settling and stabilising over the last two million years to the level we hominids know as normal.
The temperature also bounces around an awful lot but if, as the high priests of climate change claim, the temperature changes are in sync with the dance moves of Carbon Dioxide, it is very hard to identify exactly what dance they are doing.
At the start of the chart the planet is in the depths of an ice age while the C02 levels are at extremely high levels. The correlation between the two is non-existent. And while there are two apparently matching spike and falls, on one of them it is the temperature that leads and the C02 that follows and on both occasions the movements are millions of years apart, not the 200 years that today’s ’cause/effect’ scientists are claiming.
But look at 440 million years ago and see the temperature plummet to ice age levels while C02 levels spike. Then 320 million years ago the reverse happens C02 levels fall dramatically while the temperature soars to the hottest levels in earth’s record. Exactly the opposite of what today’s hand-wringers claim is proven fact.
Again have a look at the above chart at the line of 200 million years ago. There you see a big spike in C02 levels having no effect on temperature. 146 million years ago we see the anomaly of a massive temperature drop at the same time as a massive increase in C02 levels. Then as the C02 levels drop dramatically over subsequent millennia, the temperature begins to rise even more dramatically, quite against the theory that there is a correlation between the two. Then around 50 million years ago, between the Paleocene and Eocene epochs, we see one of the most dramatic global warming periods in earth’s history at a time when C02 levels were falling significantly.
So I am not a ‘climate change denier’. The point I raise from the above chart is not whether there is climate change, but in fact why would we ever think that climate change, the warming and cooling of the planet and the raising and lowering of C02 levels, are anything other than normal natural processes that have continued throughout the eons.
The issue for us is that our ancestor, homo erectus, evolved about 2 million years and our sapiens species is only 200,000 years young; so an ice age with low C02 levels is the only climatic condition our species has ever known. So let’s not be barraged into accepting a doomsday panic and giving the ‘end of the world is nigh’ high priests a blank chequebook to fund global conferences for their ‘conversations’. Let us only consider what impact the current climate observations and speculations might practically have on the lifestyle of our ice age species.
When I say climate change, what do you think that means? The scientists work, of course, off average mean temperatures when they get into this global warming issue. You might be surprised to know (I was) that the global mean temperature today is about 14-15 degrees celsius. That, for reference, is the average mean temperature of Wellington, New Zealand or Milan, Italy. When they talk about the global warming over the past 30-40 years, they are talking about a rise of 1 degree celsius. Back in the Miocene epoch at the last major global warming spike, the global mean temperature was another 4-5 degrees celsius higher than today, or an average of around 20 degrees C (or the current mean temperature of Brisbane Australia, but much cooler than Montego Bay, Jamaica which now averages 27 C).
And there is the misleading result of talking about ‘averages.’ A region that has a summer average of 40 degrees followed by an autumn average of 15 degrees, a winter average of minus 10 degrees and Spring of 15 degrees actually has an annual average of 15 degrees which sounds pleasant enough but in reality has 3 months of blistering heatwaves and 3 months of sub zero conditions which is a dreadful climate. And while our climate scientists at Paris and Poland go on about the C02 emissions creating a greenhouse effect which warms the planet, the reality is quite different. We have regions experiencing exceptionally hot summers at the same time as they are experiencing record breaking cold temperatures in winter across Europe, Asia and the USA. What we are experiencing is not a gradual warming from C02 gas in the atmosphere like we are living in a glasshouse, but in fact the weather become more extreme at both ends of the temperature gauge. And those extremes are not explained by C02.
In fact if we look at the period of the last 10,000 years we can see temperatures rise and fall quite notably even within the ice age condition, while C02 levels remain very stable throughout. So over this whole period, within the reasonably modern era of homo sapiens, temperatures rose and fell with no change in the C02 levels.
It just puts a little perspective into the debate and perspective is what the current climate hand-wringers seem to be ignoring. Man has been through these climate changes before with C02 having no part to play. Life goes on in those climates. Yes we would probably want to improve our air conditioning systems and some of us may end up with a beachfront property where once we had a main road between us and the sea, but we can adapt.
Having emerged from the forests 200,000 years ago, we have built our great cities and civilisations because of the ‘sapiens’ gene. We have done so through notable periods of climate change with ice caps expanding and retracting, sea levels rising and falling. We have had the imagination to adapt to our ever-changing conditions and challenges to improve our experience of life on earth.
We now need to focus our energies on more intelligent and imaginative use of resources, recycling and re-engineering to meet the climate challenges that nature and our own activities present us today. Yes we need less air polluting sources of power than fossil fuels and less ground polluting sources than nuclear power. Yes we need to regenerate forests and natural habitats. Yes we need to prepare for higher seas and more extreme temperatures, both hot and cold.
Let’s get on with it and stop wasting time with King Canute conferences that just clog up the process with hand-wringing, progress-stalling bureaucracy. And stop blaming humans as though we created carbon dioxide. For whatever caused the high levels of C02 in the atmosphere in the eons before 1800 ad, we are reasonably sure it wasn’t humans and engines. And the evidence is pretty convincing that there is no direct correlation between C02 levels and temperature.
