Dangerous climate feedback loops are increasing global warming and 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 temperatures cause 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.
For example, planet-warming pollution released by thawing permafrost – the frozen layer of soil that blankets the Arctic and other parts of the planet’s far north – increases global temperatures, which in turn helps create the hotter, drier conditions that make wildfires spread faster and burn more intensely. Wildfires release planet-heating pollution, further raising temperatures, and so on.
