Scientists find evidence of planetary carbon release valve
New Haven, Conn. (UPI) Jul 26, 2016
New evidence suggests the carbon cycle has a natural release valve - a built-in upper limit to the concentration of CO2 in the atmosphere. Some 56 million years ago, millions of tons of carbon were dumped into the air and ocean during what's known as the Paleocene-Eocene Thermal Maximum. Scientists believe it's the closest natural precedent for current global warming. But the ancient warming didn't last forever. That's because the geologic and atmospheric cycles that dictate Earth's cli ... read more
