A mathematical equation for calculating the impact of human activity on global climate change has been published by researchers at Australia's National University.
The equation has allowed researchers to estimate that climate change is occurring 170 times faster than natural forces would explain.
Scientists have understood human activity to be the primary factor driving global climate change, but the effects have never been definitively established with mathematical precision.
Professor Will Steffen headed the research team that developed the equation.He's a researcher at the Australian National University and an expert on climate change.The paper he and his colleagues put together on their research has been published in Anthropocene Review.
The authors of the study say geophysical and astronomical factors have dominated the "Earth system" for the past 4.5 billion years.By "Earth system," they mean the upper lithosphere, cyrosphere, hydrosphere, and the biosphere.
They write that the past six decades have seen human forces drive "exponentially rapid rates of change in the Earth system," which has yielded the period now dubbed the Anthropocene.
"Human activities now rival the great forces of nature in driving changes to the Earth system," they wrote.The equation around which the paper is built is now referred to by the research team as the "Anthropocene Equation," measuring human impact.[메디컬리포트=Maricor Zapata 기자]
