1. During the early Mediaeval Period, the world underwent a period of global warming. This resulted in the melting of the Arctic Ice, a fact recorded by the Imperial Chinese Navy whose fleet sailed around the Arctic Ocean without ever encountering any ice at all.
The Polar bears survived that, and indeed thrived. As we know, the penguins in the Antarctic survived too. It was a time of great and increasing prosperity. Wheat was grown in Greenland and even Scotland hosted its own rich vineyards.
2. It is claimed that we humans are producing too much carbon emissions and that carbon dioxide a known greenhouse gas is locking in the Sun’s heat which is going to devastate the planet.
When Sherlock Holmes or Monsieur Poirot are trying to identify a villain, they do not pick on someone who looks like they might be a villain. They do not ignore any obvious facts but keep an open mind until the evidence points clearly to the real villain. Finding someone standing at the scene of a murder holding a smoking gun in their hand may be all of the evidence that many would need. But it is not proof conclusive of guilt.
3. If we are not guilty of producing greenhouse gases when it seems blindingly obvious that we do do so, who on earth is guilty?
This is a little easier to explain than first it might seem. When we watch television and see a report of some volcano erupting we may be forgiven for feeling that here is one of those rare disasters.
And yet, volcanoes are much more common than we may think. On top of all the world famous volcanoes such as Mt.Etna, Krakatoa and others, the world is literally covered with them. For example, in Alaska alone there are over 80 volcanoes. Volcanoes appear all around the world. Most of them are unseen, lying in the depths of the world’s oceans bubbling away constantly.
When a volcano blows it will send up into the atmosphere a heady cocktail of greenhouse gases, including some real nasty ones too. When this output is measured it is found that the output in one day is equivalent to the entire emissions which are calculated to be output by human activity in a full year. In just one week, that volcano will add to the greenhouse gas supply the equivalent of what would take us humans seven long years to produce. But ... this is only one volcano’s output and there are hundreds of them bubbling away every day.
If our tiny output of carbon gases was to double it still would not register against nature’s own output.
4. But carbon gases are causing the greenhouse effect and we produce carbon gases so wouldn’t it be more sensible to cut down on them anyway? Yes, I do understand that if we do this it will lead to the world’s poor becoming even poorer but that is a price which we should be prepared to pay, even if the poor starve and we in the rich world become poor too.
It is true that there is a correlation between carbon gases and global warming. It is a matter of public scientific record. When failed politicians take to the stage with their large graphs displaying this fact, what they do not do is show us a scale time line with their graph.
By this trick all that the viewer sees is carbon gases up, global temperatures up and vice versa. Were they not, in their religious enthusiasm for their cause, allowing themselves to be misled they would observe that the global warming effect does not follow the global carbon gases increase, but in fact that the correlation is the other way around. Every time we have had global warming it has been followed within a few years by an increase in carbon gases in the atmosphere. Even then they still represent a very tiny fraction of gases in our atmosphere.
