There is no scientific proof of man-made global warming and a hotter earth would be ‘beneficial for humans and the majority of other species’, according to a founding member of environmental campaign group Greenpeace.
The assertion was made by Canadian ecologist Patrick Moore, a member of Greenpeace from 1971 to 1986, to U.S senators on Tuesday.
He told The Senate Environment and Public Works Committee: ‘There is no scientific proof that human emissions of carbon dioxide (CO2) are the dominant cause of the minor warming of the Earth’s atmosphere over the past 100 years. If there were such a proof it would be written down for all to see. No actual proof, as it is understood in science, exists.’
Moore pointed out that there was an Ice Age 450million years ago when CO2 was 10 times higher.
He said: ‘There is some correlation, but little evidence, to support a direct causal relationship between CO2 and global temperature through the millennia. The fact that we had both higher temperatures and an ice age at a time when CO2 emissions were 10 times higher than they are today fundamentally contradicts the certainty that human-caused CO2 emissions are the main cause of global warming.’
Even if the earth does warm up, Moore claims that it will be to the advantage of humans and other forms of life, as ‘humans are a tropical species’.
He said: ‘It is extremely likely that a warmer temperature than today’s would be far better than a cooler one.’
Humans, he added, just aren’t capable of predicting global temperature changes.
Moore said that he left Greenpeace because it ‘took a sharp turn to the political left’.
Dr Doug Parr, Chief Scientist at Greenpeace UK, told MailOnline: ‘On climate science, Greenpeace accepts the consensus view put forward by 97 per cent of climate scientists, every national and international scientific institute and every government in the world – climate change is happening, it’s caused mainly by human activity, and it’s highly dangerous for the future well-being of people on this planet.’
Moore has made several other assertions over the years that have been at odds with Greenpeace’s views. He has advocated logging, claiming it actually causes reforestation, and attacked campaigners for fear-mongering over nuclear energy.
His latest comments came as two of the world’s leading scientific organisations warned that man-made global warming is worsening and will disrupt both the natural world and human society.
The U.S. National Academy of Sciences and the Royal Society, which is the national scientific academy of the United Kingdom, are releasing an unusual plain language report on climate change that addressed 20 issues in a question-and-answer format.
‘People do have persistent questions all about climate change,’ said study author Ben Santer of the Lawrence Livermore National Lab in California. ‘This is a one-stop shop for many of those questions.’
The report, released on Thursday, addresses new issues such as the recent slowing in the increase of world temperatures and how heat-trapping gases are connected to extreme weather. Increases in extreme weather, melting glaciers, rising seas and oceans getting more acidic are already happening, the 36-page report said.
And those changes ‘are expected to increase greater warming and will threaten food production, freshwater supplies, coastal infrastructure and especially the welfare of the huge population currently living in low-lying areas,’ the report said.
The report said that while the rate of warming is slower in the 2000s than it was in the 1990s it doesn’t negate the 150 years of observations that show the world is warming. The report also says that more the 90 percent of the heat trapped by greenhouse gases lately has been absorbed into the oceans’ deep water, which for a while slows surface warming but not the long-term trend.
There is enough evidence on the science to warrant action, Sir Paul Nurse, president of the Royal Society, said in a news release.
‘We’ve changed the chemical composition of the atmosphere; that’s not a belief system. We know that beyond a shadow of a doubt,’ Santer said in an interview. ‘We ignore this at our peril.’
