A sharp plunge in ocean calcium levels may be the missing link in Earth’s long transition from a hot, dinosaur-era greenhouse ...

Scientists have uncovered a surprising mechanism that may explain how Earth cooled dramatically after the age of dinosaurs.

Evidence from fossil shells suggests that falling seawater calcium helped lock away carbon dioxide and helped cool Earth after the dinosaurs.

A 66 million-year-old mystery behind how our planet transformed from a tropical greenhouse to the ice-capped world of today has been unraveled by scientists. Their new study has revealed that Earth's ...

A research team has shown that methanogens, micro-organisms ubiquitous in low-oxygen environments like aquifers, soil and even permafrost, can propel their growth by dissolving calcium carbonate, one ...

Undertake a design project to construct, test, and modify a device that either releases or absorbs thermal energy by chemical processes. In Chapter 5, students learned how the process of dissolving ...

A University of Nebraska–Lincoln research team has identified new microscopic players in the global carbon cycle, a discovery that paints a clearer picture of carbon flow through the environment and ...
