In a scientific first, researchers have developed a mathematical equation to capture mankind’s impact on Earth — finding that humans are causing the climate to change 170 times faster than natural forces.
The Australian National University announced the discovery on Sunday, claiming evidence shows human-caused greenhouse gas emission during the past 45 years has increased the rate of temperature rise to 1.7 degree Celsius per century, “dwarfing the natural background rate,” according to Will Steffen, a climate change expert and ANU professor.
“Over the past 7,000 years the primary forces driving change have been astronomical — changes in solar intensity and subtle changes in orbital parameters, along with a few volcanoes,” Steffen said in a news release announcing the equation. “They have driven a rate of change of 0.01 degrees Celsius per century.”
