New Research Shows Global Warming Before Humans Arrived


New research is showing that global warming was here long before humans came unto the scene. University of Adelaide Professor Alan Cooper found that “extinction events” matched up with quick and fast warming events, temperatures fluctuated between 4ºC(39ºF) and 16ºC(60ºF) causing changes to the earths rainfall and vegetation. The animals of the time had a difficult time coping with the change and died out or spread out and thinned. This caused many species to go missing from Europe and North America, or Alaska and the Yukon, northwest Canada. These quick and fast warming trends happened some 12,000-60,000 years ago right before humans showed up on earth.

“But it was climate change that had done all the damage, reduced the populations down to small sizes and in many cases wiped out the species from most of the planet, even before humans turned up,” Professor Cooper said, speaking from Wyoming, US, on fossil dig at Natural Trap Cave.


That’s not to say that humans don’t have an impact on global warming or climate change, it’s just common sense that we all have an affect on our environment. But we do know now that global warming and climate change are nothing new to the earth and it’s very possible that through our advancement in technology and growth as a species, we’re affecting the earth far more than normal.

“Humans are having their impacts by interrupting that process and stopping areas that have become vacant for climatic reasons from being filled back up. That way these vacant areas can start getting bigger and bigger and start causing whole ecosystem changes.”
