Professor Michael Asten from Monash University looks at the trends in tempeature across the globe.
"Global temperatures have not increased in a statistically significant sense in the past 15 years.
A pause of 10 years in the upward trend of the past 40 years would be unsurprising from existing models. A pause of 20 years would definitely surprise. Changes across the next five years will be watched closely… but with one eye on history and one on current observations, I see no reason for pessimism about our climate".
