World temperature could rise rapidly by 2020, modelling suggests
Professor Ben Hankamer

Global warming could occur more quickly than expected, according to a new model by University of Queensland and Griffith University researchers.

The model is the first to include ' use per person' as a predictive factor rather than focusing solely on economies or populations.

It forecasts that population and economic growth combined with rising energy use per person could significantly increase and CO2 emissions, causing world to rise by 1.5 degrees as early as 2020.

The model was developed by Professor Ben Hankamer from UQ's Institute for Molecular Bioscience (IMB) and Dr Liam Wagner of Griffith University.

"Nations at the 2015 UN Conference on Climate Change agreed to keep the rise in below 2 degrees Celsius, preferably limiting it to 1.5 degrees to protect island states," Professor Hankamer said.

"Our model shows we may have less time left than expected to prevent world temperature from rising above these thresholds.

"World population is forecast to increase to over 9 billion people by 2050, which, together with international 'pro-growth' strategies, will lead to continually increasing energy demand.

Professor Hankamer said it was vital to move from CO2-emitting fossil fuels and tap into renewable resources to accommodate these increases while controlling temperature.

"The sun is by far the largest renewable energy source," he said.

"In just two hours it delivers enough solar energy to the Earth's surface to power the entire global economy for a year – and now is the time to make the switch.

"A cost-neutral strategy that governments should consider to fast track this transition is diverting the $500 billion used to subsidise the fossil fuel industry internationally to assist the global renewable sector."

Dr Wagner said the model challenged the assumption that increases in energy efficiency and conversion would offset increases in demand.

"We have successfully applied our model to world from 1950-2010 and demonstrated that increases in energy efficiency alone don't offset the surge in in energy use per person," he said.

"Simply put, as we get more efficient at manufacturing, goods get cheaper and we buy more.

Dr Wagner said massive increases in energy consumption would be necessary to alleviate poverty for the nearly 50 per cent of the world's population who live on less than $2.50 a day.

"We have a choice: leave people in poverty and speed towards dangerous through the increased use of fossil fuels, or transition rapidly to renewables.

"As 80 per cent of world energy is used as fuels and only 20 per cent as electricity, renewable fuels in particular will be critical."

Dr Ian Ross from IMB and Professor John Foster from UQ's School of Economics were integral in developing the . The work is published in the journal PLOS ONE.

Dyson says the models used to predict the climate are fatally flawed.

Dyson knows diddly-squat about climate sciences. It's about as good an argument as saying: Pee-wee Herman says the climate models are flawed.

When Dyson says your maths are rubbish, they likely are.

At least learn to cite Dyson correctly. At no point does he say the math is rubbish. He is just unsure that all relevant factors are accounted for. But that is just a "god of the gaps argument". At no point does he say AGW isn't happening, BTW. He's just not sure.

In the end it's sort if bizarre. All we ever hear the anti-AGW crowd saying is: "I have no clue how science works - so it must be wrong because I'm a genius"

If you think that line of argument is particularly good, think again. Genius.
