Dangerous climate feedback loops areincreasing global warmingand risk causing a permanent shift away from the Earth’s current climate, according to a new study.

Climate feedback loops are cyclical chain reactions that happen when one change triggers further changes, in a process that keeps on repeating itself. Some of these feedback loops drive down warming, but others amplify it.

Take Arctic ice, for example. Warming temperaturescause sea ice to melt, revealing the dark ocean water beneath. As dark surfaces absorb more heat than reflective surfaces like ice, the ocean warms and more ice melts.
