Australian researchers say a global tracker monitoring energy use per person points to 2C warming by 2030

The world is on track to reach dangerous levels of global warming much sooner than expected, according to new Australian research that highlights the alarming implications of rising energy demand.
University of Queensland and Griffith University researchers have developed a “global energy tracker” which predicts average world temperatures could climb 1.5C above pre-industrial levels by 2020.
That forecast, based on new modelling using long-term average projections on economic growth, population growth and energy use per person, points to a 2C rise by 2030.
The UN conference on climate change in Paris last year agreed to a 1.5C rise as the preferred limit to protect vulnerable island states, and a 2C rise as the absolute limit.
The new modelling is the brainchild of Ben Hankamer from UQ’s institute for molecular bioscience and Liam Wagner from Griffith University’s department of accounting, finance and economics, whose work was published in the journal Plos One on Thursday.
It is the first model to include energy use per person – which has more than doubled since 1950 – alongside economic and population growth as a way of predicting carbon emissions and corresponding temperature increases.
The researchers said the earlier than expected advance of global warming revealed by their modelling added a newfound urgency to the switch from fossil fuels to renewables.
Hankamer said:
“The more the economy grows, the more energy you use … the conclusion really is that economists and environmentalists are on the same side and have both come to the same conclusion: we’ve got to act now and we don’t have much time.”
