Two dire studies show the world is on the brink of locking in dangerous levels of climate change.

In separate reports published Monday, researchers found that only a short window of opportunity remains to prevent widespread, irreversible planetary-scale impacts.

The two studies reveal that factoring in current emissions, as well as a wide range of future trends, we may have already locked in a temperature rise surpassing the universally agreed-upon global warming target of 1.5 to 2 degrees Celsius — which the 2015 Paris accord sought to set as an upper limit.

If all the world’s human-derived sources of greenhouse gases stopped today (which obviously will not happen), by 2100 global temperatures would stabilize somewhere between a temp slightly cooler than the current average and about 2.3 degrees higher than preindustrial levels, according to the first study.
