Cosmic Cycles, not Carbon Dioxide, Control Climate.

Those who think the political war on carbon will lower Earth’s temperature or keep climate stable need to study climate history.

Temperatures on Earth dance to a cyclic rhythm every hour, every day, every month, every season, every year, and to every beat of the sun-spot and glacial cycles.

The daily solar cycle causes continual changes in temperature for every spot on Earth.

It produces the frosts at dawn, the mid-day heat and the cooling at sunset. It is regulated by rotation of the Earth.

Superimposed on the daily solar cycle is the monthly lunar cycle, driven by the orbit of the Moon around the Earth. These two cycles interact to produce variations in atmospheric pressure and tides, and currents in the oceans and the atmosphere.

These are the daily weather makers.

The yearly seasonal cycle is caused as the tilted axis of Earth’s rotation affects the intensity of solar energy received by each hemisphere. This produces spring, summer, autumn and winter for every spot on Earth.

Then there is the 22 year sun-spot cycle, which correlates with cycles of floods and droughts. Sunspot cycles are indicators of solar activity which causes periods of global warming and cooling.

Variations on the sun also affect the intensity of cosmic rays reaching Earth’s surface – cosmic rays create nuclei for low level cloud formation, and the shading from such clouds reduces surface temperatures.

Earth’s climate is also disrupted periodically by the effects of changing winds, ocean hot spots and submarine volcanism that produce the El Nino Southern Oscillation.

The least recognised but most dangerous climate cycle is the glacial cycle. We are fortunate to live in the Holocene Epoch, the latest warm phase of the Pleistocene Ice Age.

The climate history of the Holocene, and its predecessor the Eemian, are well documented in ice core logs and other records in the rocks. Each cycle consists of a glacial age of about 80,000 years followed by a warmer age of about 20,000 years, with the peak warming occurring over about 12,000 years.

Our modern warm era commenced 12,000 years ago and peaked during the Medieval Warming, so it is probably nearing its end.

The Holocene Warmth as revealed by the Greenland Ice Cores.

The Eemian Warm Period was warmer than today.

There have been eight warm eras separated by long glacial winters over the last 800,000 years of the Pleistocene.

In every beat of this cycle, the vast ice sheets melt, sea levels rise dramatically, coral reefs and coastal settlements are drowned, and forests and animals re-colonise the higher land released from the ice.

Warm climate animals such as hippos, water buffaloes and elephants got as far north as Germany in the last warm era.

Then suddenly the ice returned, covering the northern hemisphere as far south as Chicago and London, destroying the forests, lowering the seas, stranding the relocated coral reefs and eliminating unprepared species. (Some dopey grizzly bears got stranded in the Arctic Ice and the most enterprising of them survived to evolve into white grizzlies now called polar bears.)

This regular repetition of natural climate change is partially explained by the Milankovitch cycles relating to changes in Earth’s precession, orbit and tilt.

These drive variations in solar energy received by Earth and have the greatest temperature effect on the large land masses of the Northern Hemisphere.

On an even longer time scale, oscillation of the solar system through the plane of the Galaxy seems to trigger magnetic reversals and violent spasms of volcanism, crustal movements, glaciation and species extinction. Earth is never still for long.

These cycles interact to produce a wide range of ever-changing temperatures.

Even at the same moment, temperatures vary dramatically from the equator to the poles and from the surface to the stratosphere.

For would-be climate “managers” to claim they can calculate a mythical “global temperature” with precision greater than thermometers can measure is statistical nonsense.

It is a wonder of the modern era that people who cannot accurately forecast next weekend’s weather claim they can regulate the temperature of the whole globe by bashing industry and taxing carbon.

What is the role of carbon dioxide in climate?

Al Gore did a great job to dramatise the recurring glacial cycles in his widely acclaimed work of science fiction.

But he missed two inconvenient truths.

First, ice cores show that in the glacial spring-time the temperature rose BEFORE the CO2 levels rose.

Therefore the rising CO2 cannot be a CAUSE of the warming – it is a RESULT of CO2 being expelled from the warming oceans.

Second, at the top of every summer-time in the glacial cycle, the high levels of CO2 in the atmosphere were unable to prevent the cooling into the next cycle of ice.

We are already in the autumn of the current glacial cycle and nothing man can do will change that.

Global temperatures today are lower than they were in Roman and Medieval times.

They will still fluctuate with the effects of daily, lunar, yearly and sun-spot cycles, but the long-term trend of maximum and minimum temperatures will continue drifting downwards.

Once summer temperatures in places like Siberia are unable to melt last winter’s snow, the already growing glaciers will join to form ice sheets and Earth will once again be gripped by another long Glacial Winter.

The transition from Greenhouse Earth to Icehouse Earth always occurs suddenly. Once our verdant greenhouse is gone, life on Earth will never be the same again.

Greenhouse Earth will surely come around again, but many of today’s species will probably not survive to welcome the return of the warmth.

The warm days, seasons, years and epochs have never been a deadly threat to life on Earth. Frost, snow, hail and ice are the killers.

If our descendants do not have the energy, resources and wisdom to keep their people warm and fed through the coming glacial epoch, humans may follow our Neanderthal cousins who perished in the last glacial winter, just 20,000 years ago.

There is NO evidence in climate history that carbon dioxide has a detectable effect on global temperatures.

However if our continued use of cheap reliable hydro-carbon energy does slightly delay the onset of the next glacial winter, we and all life on Earth should count ourselves extremely lucky.
