New numerical method 170 times faster than natural forces

Scientists in Australia and Sweden have created the equation, which evaluates the impact of human activity on the climate and match it up to events such as volcanic eruptions and amendments to the planet’s orbit.

Professor Will Steffen, a climate scientist from the Australian National University (ANU), said no natural events draw closer to the impacts humans have made.

He further added,” Over the last century or so, we can see that the impact of humans — through fossil fuels, through forest clearing, through all sorts of changes to the biosphere — have become more important than these other forces”.

Professor Steffen’s formula, produced with scientists from Sweden’s Stockholm Resilience Centre, bring into play variety of dimensions of the natural world.

“This uses things like changes in solar intensity, changes in the Earth’s orbit around the sun, massive volcanic eruptions, perhaps a meteorite strike like the one that knocked out the dinosaurs,” he added.

“These sorts of things are traditionally the forces that change the state of the entire Earth over long periods of time.”
