A cosmic indian summer

Is the average temperature on earth higher today than it was a century ago when industrialisation expanded throughout the globe to meet the needs of a rapidly growing population? It is actually not as easy as you might expect to find the answer amongst the plethora of press releases from the climate alarmists. From all the micro data that the climate alarmists are extracting, analysing and dispensing, why is it so hard to find a simple list of actual seasonal temperature recordings over the last one hundred year period in any given location? Instead we get charts of variations of temperature from the norm (although rationalising what ‘the norm’ is and when the norm supposedly happened seems to be just ignored). They provide charts of ‘moving averages over years’ with the years selected to ‘prove’ a trend entirely at the writer’s discretion. And while the internet is absolutely overwhelmed with alarmist headlines, basic, actual temperature data over 100 years, separated by season is very, very hard to find. But I eventually did find one. It was from Britain. Have a look at these actual seasonal temperatures over the last hundred years in the country that birthed and led the industrial revolution and tell me where you see any temperature trends that would alarm you.

So as a brief scan, in Central England in 1912, the year the Titanic sank and the coal miners went on strike, the average winter temperature was 5.36, spring 8.53, summer 17.55 and autumn 10.39.

At the start of the ‘Boomer’ generation in 1948, winter was 5.13, spring 8.75, summer 17.50 and autumn 11.15.

In swinging 1965, the year Gen. X was born, winter was 3.28, spring 8.43, summer 15.71 and autumn 10.40

In 1981 the year the ‘Millennials’ arrived on earth, winter was 4.33, spring 9.17, summer 15.06 and autumn 10.12

And at the dawn of the 21st century winter was 5.35, spring 9.49, summer 16.45 and autumn 11.57.

I could take three summers spread over this period of 2000, 1948 and 1912, draw a connecting line and claim that the climate has since cooled by 1 degree over the century.  I would not do that of course, three points over a 90 year span does not make a valid data base. Yet the alarmists fill the media and internet with no more than micro data snippets to make their claims. So just look over the above 100 year chart as a total group or a random handful and just ask yourself, do these temperatures alarm me? 

According to the best astrophysics information we have, our temperatures are, unsurprisingly, linked with the natural orbit of the earth around the sun, which is a changing environment and by no means a perfect circle as we might have assumed. Milutin Milankovic, a contemporary of other mathematics and physics geniuses Einstein, Minkowski and Tesla, demonstrated the way our solar system works. Milankovic’s calculations remain valid today having been constantly reviewed with all the computing support to which modern astrophysicists have access. 

In brief, there are three cycles contained in the way earth orbits the sun: tilt, precession and elliptic; and the elliptical plane changes quite dramatically every 100,000 years. Not surprisingly, the glaciation of our planet also works on this 100,000 year cycle. 

During a glacial period the planet cools as the heat of the sun moves further away, the air dries out and water levels fall as liquid is transformed to ice. Land bridges start to become available and islands appear where before they were part of the sea bed.

If we just look back 400,000 years we have scientific consensus from both sides of the climate debate on the temperature cycles as per the chart below. And all agree that the cycle started to cool down again about 6,000 years ago. What we don’t have consensus on is ‘where to from here?’ As below, the alarmists little arrows project, with no mathematical base that I can see, that the temperature heads rapidly due north towards a hell on earth scenario. They state that the cooling of the planet over the previous 6,000 years suddenly u-turned just 100 or so years ago when industrialisation, motorised transport, steam ships and smoke belching trains started to take hold around the globe.

They ignore, of course that even today, with a population passing 7.5 billion compared to 2.5 billion in 1950, human generated C02 represents only 3% of total C02 which was confirmed in this EPA document (click to enlarge). 

As a brief history of our climate in this current ‘inter glacial’ period, when the last glacial episode officially ended Canada was still under 2+ kilometres of ice and it was possible to walk across the Bering straight from Eastern Europe to North America. Aborigines could also island hop from South East Asia to Australia as could the Celts cross from Europe to Britain. Our planet had been in that ice age for the previous 100,000 years. Over the first 6,000 years of this inter-glacial phase the ice mountains melted  and the oceans rose dramatically, submerging islands and causeways and possibly even a small continent if the legend of Atlantis has any basis in fact. The sea height has levelled out since then. 

Basing projections on historical patterns, which are linked to the orbit of the earth around the sun, we are in fact right now coming towards the end of a cosmic Indian Summer and we will gradually move back towards a much cooler planet and in about 90,000 years we will again have Canada, Northern Asia and Europe all underneath kilometres of ice sheet.

The reason for the heightened anxiety of the alarmists is that today our scientists are micromanaging data and constantly tweeting bite size doomsday headlines that simply are not supported by the bigger picture trends. The climate works in tens of thousands of years, not in months. The last time humans went through this climate cycle they were blissfully unaware of the fact that there even was a cycle; it was a pleasant and warm time and they probably just enjoyed it; a few hundred generations later the climate was comparatively much colder, but they did not know it was colder because they had no records to analyse; it just was what it was. Too much micro analysis of climate data on a month by month basis is just creating hyper anxiety and panic.

But ‘getting it wrong’ is not the reason I speak up against the climate alarmists. It is because they have the right problem for the wrong reason and that makes them counter productive to solving our environmental challenges. It is because, even as they march on their Friday strikes and fly around the globe in their thousands to attend conferences and draft resolutions, they are just plucking temperature levels and deadlines out of the air about when we may reach the point of no return which target seems to be a  shifting landscape. In 2008 the tipping point was predicted to be 1 August 2016; in 2016, following the Paris Agreement which set 2 degrees as the tipping point, IIASA (science institute) policy brief said we had until to Dec 31 2020 to keep warming under 2 degrees; as that date approaches the 2019 climate summit in September says we can still get under the 2 degree tipping point within 12 years so that takes us out to 2031. Prince Charles is a little more optimistic and thinks we have until 2050. And now there is another big pre Christmas conference in Madrid, delegates from 200 countries, they apparently need to tidy up some details from the 2015 Paris Christmas party, oops I mean conference, and maybe review the next tipping point date.

Fossil fuel over-use is not a problem of climate, it is a problem of health. Instead of talking about the ‘invisible demon’ C02 and the inevitable ‘Mad Max’ scenario, all because of the industrial sins of our forefathers, we need to be talking about investing in better technology to reduce lung-damaging air pollution in our cities. We need new technology to prevent pollution of our farming soils and our waterways that poison our food and water sources. When we get rid of the climate doomsday message and focus on health solutions then we might start making some progress. Right now the climate alarmists are only creating a climate of doom and hopelessness. And that carries the risk of being a self-fulfilling prophesy.
