Evidence of cooler Earth but nature follows its own path

THE letter by Duncan of Elanora (GCB 17/7) cannot go unchallenged.

I am a former medical scientist employed by both the Australian Government and with extensive experience seconded to the World Health Organisation under the United Nations.

The planet Earth is currently much cooler now than in earlier periods where the tropical disease malaria was endemic in England and other areas far from the equator, but much too cold for that now.

Grain was a major crop in Greenland but is now too cold for this crop. Earth core samples taken deep down through the planet’s layers are considered to be a reliable guide to past history, so, such samples taken across wide areas of Northern Europe have shown seeds of tropical plants, but too cold now.

There are many examples that confirm that Earth is now much colder than earlier periods of history.

But Emeritus Professor Plimer, professor of Earth Sciences and Geology (he has published more than 130 scientific papers and edited the Encyclopedia of

Geology) has this to say ... “There are more than 200 volcanoes and if we look at just one eruption, in Iceland, the volcanic ash emitted in just four days was sufficient to negate every single effort to reduce carbon to date.

“Likewise, Mt Pinatubo in the Philippines in 1991, spewed out more greenhouse gases in that one year into the atmosphere than the entire human race had emitted in all its years on Earth.

“Even seemingly innocent events such as the regular bushfires in California and parts of Australia, will in a single year alone be enough to negate any efforts to reduce carbon for the next two to three years, and it happens every year ...

“In this period of pushing the global warming fable, the Earth has actually cooled by 0.7 degrees ...”

It is obvious nature will follow its own laws regardless. DR GRAHAM SAYER, GOLD COAST
