REALITY CHECK NEEDED BY CLIMATE DISCIPLES
Cosmic Cycles Control Climate
by Viv Forbes, Science writer
Those who think a war on carbon energy will lower Earth’s temperature need to study climate history.
Temperatures on Earth dance to a cyclical rhythm every hour, every day, every month, every season, every year, and to every beat of the sun-spot and glacial cycles.
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 even sillier for people who cannot accurately forecast next weekend’s weather to claim they can regulate the temperature of the 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 revealed by ice cores 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 warm cycle, high levels of CO2 in the atmosphere were unable to prevent Earth from cooling into the next cycle of ice.
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. These show that today’s warm Greenhouse Earth is probably nearing its end. It will be followed by Icehouse Earth.
There is no evidence in the climate records 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 lucky.
Viv Forbes is a qualified geologist who has spent much of his life studying geological and climate history as written in the rocks. He has also spent several years in formal and private study of climatology and meteorology. He is the Founder of the Carbon Sense Coalition and a non-executive director of a small Australian company developing a coking coal mine.
By far the best reference book I have read on the above subjects is:
“The Inconvenient Skeptic” by John Kehr. This book is written in plain language, but full of sound science, well researched and referenced. I highly recommend it for those wishing to understand what drives our climate. (Hint: It is NOT carbon Dioxide.)
Another well-researched and easy-reading book on the long term cycles of ice ages and volcanism is:
“Not by Fire, but by Ice” by Robert Felix:
Original Research on Sunspots and Rainfall Cycles – Prof Will Alexander:
The Holocene Warmth as revealed by the Greenland Ice Cores:
The Eemian Warm Period was warmer than today:
