Dispelling Delusions: Human-Caused Climate Change and Carbon “Pollution” Mythology

By Dr G LeBlanc Smith, PhD, AIG, AAPG

As a retired CSIRO Principal Research Scientist (geosciences - sedimentology), I make this observation and comment on Minister Wong�s statement, (and Professor Garnaut’s commentary): �Climate change threatens icons like the Great Barrier Reef, the Kakadu wetlands and the multi billion dollar tourism industries they support.� Knowing and understanding the past is a vital key to the future, and earth scientists can present much of this information in a context that can assist in exposing the truth and misrepresentations of the current “Climate Change” debate. It is fact that the vast bulk of the Great Barrier Reef area was exposed land and above sea level, prior to 10,000 years ago, when sea levels were over 70m lower than present. There was no great coral reef there until recently, and Kakadu was probably not a swampy wetland then either.

I suggest that statements from Ms Wong and Professor Garnaut should be challenged for veracity by all responsible Government advisors and the CSIRO at the very least, and by any observant scientist to test their logic against evidence.

The evidence can be seen from the history of sea level variations mapped as a time-curve derived from joining dots of observed and dated sea levels that track the natural melt-out of the last glaciation ice sheets. Sea level has risen about 130m in the 10,000 years between 17,000 and 7,000 years ago; with a maximum observed level ~8m above present sea level in marine deposits dated ~ 6000 years old in perched Antarctic lakes. It has subsequently fallen in steps as the planet has cooled to our present level. This is in the published science literature and much can be readily “Googled”.

More solid facts from the past: It is established fact that the ice core data from both Greenland and Antarctica show information that carbon dioxide variation lags behind temperature variation, throughout the nearly half a million year record contained in the ice cores.

In summary, I have yet to see credible proof of carbon dioxide driving climate change, yet alone man-made CO2 driving it. The atmospheric hot-spot is missing and the ice core data refute this. When will we collectively awake from this deceptive delusion? I contend that those professional scientists and advisors that are knowingly complicit in climate science fraud and all that is derived from it, will continue to be exposed by the science itself. There is no atmospheric hot-spot from “greenhouse CO2” despite over 20 years of serious looking for it (read Dr Evans and Dr Spencer’s recent media and US Senate evidence statements). Occam’s razor would point to the sun as the driver of climate change of significance. Human generated carbon dioxide is arguably around 3% of the total carbon dioxide budget, and in the light of the above, we are effectively irrelevant to the natural climate change continuum.

There was a strong El Nino in 98 that was responsible for a large portion of the infamous 20th century warming period.The fact is that global temps have been flat from 02 to 07 and dropped so much in 08 that all of the warming of the modern warm period (75 to 02)has been wiped out. So Technically, there has been no net warming since 75.The past year marks the change to cold phase of the PDO. Get ready for 30 year of cooling. The PDO cycle is approximately 30 years of warm followed by 30 year of cool. Nothing new here, just more natural cycles.
The Solar influence has NOT been debunked and is indeed the dominent driver for the ocean cycles that actually drive climate.
CO2 plays a very small roll in warming and is only pushed by the multibillion dollar AGW industry to shame the ignorant into forking over their money.
