I BELIEVE Dr Jito Vanualailai’s mathematical approach to climate change (pg.25, FT 30/11/15) is very relevant but in the light of Dr David Evan’s recent research incorrect (Sydney Morning Herald, 3/10/14). Dr Evan’s states the new corrected model finds the climate’s sensitivity to carbon dioxide (CO2) much lower than was thought.

CO2 has an effect but it’s about a fifth or tenth of what the IPPC says it is.

CO2 is not driving the climate and has caused less than 20 per cent of the global warming in the past few decades.

Dr Evans’ solar activity theory “albedo modulation” shows the waxing and waning of reflected radiation from the sun is the likely cause of global warming.

Dr Evans, a former modeller for the Australian Government’s Greenhouse office, has six degrees in applied mathematics, an expert in Fourier analysis and digital signal processing and two degrees from Stanford University including a Masters in Applied Maths from Sydney University.

He predicts global temperatures will begin to cool significantly beginning between 2017 and 2021.

If he turns out to be correct he has proven the theory on carbon dioxide wrong and explained why the doomsday predictions of climate scientists aren’t reflected in actual temperatures.

Just another welcome addition to what may well turn out to be the greatest political scam in history surpassing the Y2K bug of 2000.

I believe climate change conferences are a spectacular farce and funding would be better spent on medical research and scientific pursuit.

I believe the bigger nations are just dirty and need to tidy up their act and set the example for a cleaner world.
