As we go about our daily lives, the carbon-rich soils of the boreal forest and lush rainforests of the tropics are hard at work sucking up carbon dioxide, forming what are known as terrestrial carbon sinks. As a result, every year, land-based ecosystems absorb more CO2 than they emit. From 2007 to 2017, they removed about a third of total anthropogenic emissions<\/a> from the atmosphere. <\/p>\n But three potential tipping points in the terrestrial system \u2014 one in the Arctic, one in the sub-Arctic, and another near the equator \u2014 could force the release of huge amounts of carbon stored within those sinks. Once those thresholds are passed, feedback loops might start spiraling, accelerating climate change and reshaping our planet\u2019s forests and soils. <\/p>\nPermafrost<\/strong><\/h3>\n
