Lottie Peppers on 22 Jan 15An "excuse me" might be nice. Researchers have found that Earth belches a potent greenhouse gas known as tetrafluoromethane (CF4) during earthquakes and other tectonic events. The emissions likely aren't making a significant contribution to global warming, but the findings could change the way scientists model future climate scenarios. They also complicate the use of CF4 as a way to measure how the continents and climate have changed over millennia.
