Story summary

UC Riverside researchers warn global warming could trigger an ice age through carbon-cycle mechanisms, in a Science study.
Biological carbon burial may outpace rock weathering, driving substantial cooling and reducing atmospheric CO2.
Simulations show temperature drops exceeding 6°C, potentially creating ice age conditions.
Global warming remains the main concern for the coming centuries globally.
