Study Shows Men's Negative Impact on Climate
Human beings cause the climate to change 170 times faster than natural forces, according to a study by an international team published today.
In order to prove this hypothesis, they applied a mathematical formula to describe the impact of human activity on the Earth system, known as the Anthropocene equation.
According to the authors in The Anthropocene Review, during the past 4.5 million years, astronomical and geophysical factors dominated the leading influences of the Earth system.
But during the last six decades, human forces operated exceptionally fast rates of change in our planet's system, providing the period known as Anthropocene, they acknowledged.
That is why Will Steffen, of the Australian National University (ANU) and his colleague, Owen Gaffney, of the Stockholm Resilience Center, managed to elaborate the Anthropocene Equation, which determines the impact of human activities in this period.
In explaining this formula, Gaffney asserted that it was developed by locating it in the rate of change of the life support system on Earth.
Referring to Steffen, we are not saying that the astronomical forces of our solar system have disappeared, but in terms of their impact in such a short period of time they are now insignificant compared to our own influence.
If we fail to reduce the importance of climate change could trigger a collapse of societies, concluded Steffen and Gaffney.
