The eight limits the study looked at were climate, air pollution, phosphorus and nitrogen contamination of water from fertilizer overuse, groundwater supplies, fresh surface water, the unbuilt natural environment and the overall natural and human-built environment. Air pollutionwas the only planetary limit that wasn't quite at the global danger poi...
“We are in a danger zone for most of the Earth system boundaries,” said study co-author Kristie Ebi, a professor of climate and public health at the University of Washington. If planet Earth just got an annual checkup, “our doctor would say that the Earth is really quite sick right now,” Earth Commission co-chair Joyeeta Gupta, a professor of envir...
The team of about 40 scientists created quantifiable boundaries for each environmental category, both what’s safe for the planet and the point at which it becomes harmful for groups of people, which the researchers termed a justice issue. Rockstrom said he thinks of those points as setting up “a safety fence’’ outside of which the risks become high...
The report uses the same boundary of 1.5 degree Celsiusof warming since pre-industrial times that international leaders agreed upon in the 2015 Paris climate agreement. The world has so far warmed about 1.1 degrees Celsius, so it hasn’t crossed that safety fence, Rockstrom and Gupta said, but that doesn’t mean people aren’t being hurt. “What we are...

The latest climate science. Scientists have long warned that 1.5°C is a physical limit, not a political target. Tipping points are critical thresholds beyond which a system reorganises, often abruptly and/or irreversibly, according to the IPCC. Breaching 1.5°C has a domino effect – triggering critical changes in Earth systems that reinforce ...
