A new study has revealed that the production of greenhouse gases was not limited to the modern age.
When we think of global warming we tend to think of factories churning out greenhouse gases in to the atmosphere, but now it seems that the production of such gases was prevalent long before industrialization and long before anyone knew anything about climate change. The ancient Roman and Chinese empires would have been prime contributers, burning large amounts of plant matter and releasing millions of tons of methane gas in to the atmosphere.
"The quantities are much smaller, because there were fewer people on Earth," said study leader Celia Sapart. "But the amount of methane emitted per person was significant."
"Sapart's conclusions were based on an analysis of ice core samples from Greenland."
