Humans are changing the climate 170 times faster than natural forces, according to new research from The Australian National University.
Natural forces include things like the intensity of the sun, volcanoes and changes in Earth's orbit. Those have only increased the global temperature rates by 0.01 degrees Celsius per century.
But human-caused greenhouse gas emissions over the past 45 years have bumped up the rate of the global temperature rise to 1.7 degrees Celsius per century.
Greenhouse gas emissions have implications on ecosystems worldwide. Last year, the Great Barrier Reef experienced its worst coral bleaching ever recorded.
The researchers say the human impact on global warming is so strong that nature's effect is pretty much zero.
