Data from the tiny fossil shells, and data from new climate model runs, show that high latitude (~ 65 ° S) sea temperatures were in excess of 20 °C. (phys.org)
These results can not be used to create new climate models. (sciencedaily.com)
New climate modeling tools are incorporating observational data with climate variables to simulate future climate changes and improved approaches for observing carbon release and uptake. (pnnl.gov)
