The Earth has entered "uncharted territory" and life is "under siege." The public has failed to heed this message and now "time is up," warns a recent report from Oxford Academics' BioScience.

The authors of the report say the catalyst behind the dire warnings is escalating concentrations of carbon dioxide (CO2).

To salvage what remains, the authors say a much faster phase-out of oil, coal, and other fossil fuels is necessary. Failure could cause water and food shortages, plus extreme heat, for a third to half of the world's population.

The message is similar to that of the United Nations (U.N.), President Joe Biden, the World Economic Forum, and countless government leaders: CO2 concentrations are too high, and the continued burning of fossil fuels, which release CO2, will cause people to die.
