It is a gross exaggeration to claim that 99 per cent of scientists agree that human changes have caused climate change, as suggested in a recent DA story.

The Geological Society of Australia, Australia’s peak body of earth scientists, is just one example of scientists who continue to debate climate change theories.
In fact their society has found it “too divisive” to come to an academic agreement on climate change.
The Green Left Weekly, in urging support for last week’s People’s Climate March, was counting on the 99 per cent of green leaning activists, as well as the usual suspects that attend leftist rallies.
The UN’s planned $100 billion fund to “compensate” developing nations via carbon taxes and emissions certificates would have their support. To the marchers, climate change is an avenue to political change.
The climate change question is more complex than carbon dioxide abatement. CO2 has increased by 25 per cent in the past 16 years, but world temperatures have stabilised, meaning other factors are at work.
Meanwhile, the weather bureau has become so distracted by the lack of recent increases in world temperatures, that they have resorted to adjusting Australia’s weather records to prove their point.
“Homogenisation” is a process of applying a computer formula to historical records, comparing them to neighbouring areas, and smoothing out apparent “records” that were, well, inconvenient.
The result has been that records which showed a slight cooling now show a warming trend.
Temperature records in Britain, the USA and NZ have had similar treatment. Remember the “Climategate” leaked emails scandal several years back?
Climate activists revealed they were despairing for evidence of climate change, but had worked out ways to make the records appear to give a different result.
Dr Jennifer Marohasy, best known for her work on the Murray River, has been investigating anomalies in the new revised records.
At Bourke, for example, historic high records such as the 51.7 degrees recorded on January 3, 1909, were removed from the record because it was assumed that there had been a clerical error.
Bourke’s old records showed a 1.7 degree cooling but the new adjusted records show a slight warming.
Dr Marohasy points out that all the data for Bourke before 1910 has been discarded from the record, removing some particularly hot times from the record books. When the weather bureau needs to alter raw data to prove that warming is occurring, we should all smell a rat.
Perhaps too we need to listen to astrophysicists who have been studying sun spot activity.
They have been warning that declining activity of the sun could indicate that the Earth is heading for significant cooling during the next three decades.
The Little Ice Age had a similar sunspot pattern, with crop failures and famine. Let’s look beyond carbon dioxide for a solution.
