Here are some excerpts from Moore's speech:
'When modern life evolved over 500 million years ago, CO2 was more than 10 times higher than today, yet life flourished at this time. Then an Ice Age occurred 450 million years ago when CO2 was 10 times higher
than today.
'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.
'The IPCC states that humans are the dominant cause of warming “since the mid-20th century”, which is 1950. From 1910 to 1940 there was an increase in global average temperature of 0.5C over that 30-year period. Then there was a 30-year “pause” until 1970.
'This was followed by an increase of 0.57C during the 30-year period from 1970 to 2000. Since then there has been no increase, perhaps a slight decrease, in average global temperature. This in itself tends to negate the validity of the computer models, as CO2 emissions have continued to accelerate during this time.
'The increase in temperature between 1910-1940 was virtually identical to the increase between 1970-2000. Yet the IPCC does not attribute the increase from 1910-1940 to “human influence.”'
