It seemed hotter when I was a kid, says climate sceptic
AN Australian scientist has told a Copenhagen audience that humans are not damaging the climate - and the weather seemed hotter to him as a child.
Well-known geologist and author Ian Plimer travelled to the scene of the UN climate conference to question whether the world was warming.
"It's been freezing in Perth and bucketing down," Professor Plimer said after his lecture.
The UN's weather body, the World Meteorological Organisation, yesterday announced the last decade was likely to be the hottest on record.
Australia has had three heatwaves this year and is on track to record its third-hottest year ever.
But Prof Plimer, author of the recent best-selling book, Heaven and Earth, which questioned human-induced climate change, said: "One swallow doesn't make a summer."
The University of Adelaide professor did not make it inside the official climate conference venue, instead giving his speech to a rival conference organised by a US lobby group in central Copenhagen.
"Heretics are not allowed," he said of the UN conference.
He told the rival conference he remembered summers when he was a child being much warmer and said at the moment it was freezing in Perth and bucketing down.
Prof Plimer said he was in Copenhagen to try to stop the world engaging in the "global collective madness" of reducing greenhouse gas emissions by clamping down on economic development.
He said the climate had always changed and it was erroneous to blame emissions from people.
Other factors, like the sun, the earth's orbit and extraterrestrial factors, could be responsible.
Major ice ages had happened when carbon dioxide levels were high and there had been very warm periods before the industrial age began, he said.
