The research, published today in the scientific journal
BioScience, is not peer reviewed, but is a continuation of the 2019
climate emergency declaration, which was endorsed by over 11,000 scientists.
That number now sits at over 14,000 scientists from 158 countries.
The scientists involved chose 31 indicators that correspond to the effects of human activities on the climate, environment, and society, in an attempt to broaden discussions of climate change beyond global surface temperatures.
These indicators, which they call Earth's "vital signs", include things like human population, meat production, tree cover loss, carbon dioxide emissions, national declarations of climate emergency, and sea-level change.
The COVID-19 pandemic disrupted many of these "vital signs", but also provided insights into how a major shift in human activity can impact climate change, according to report author Thomas Newsome from the University of Sydney.
"Even with that decline in air transport and the general slowdown in human movement, it generally didn't have an overall impact on greenhouse gas emissions," Dr Newsome said.
