The authors estimate that about 200,000 temperature-related deaths could happen in the U.S. every year under an extreme but possible climate scenario.
large cities, the authors created models for what could happen to temperature-related deaths in the U.S. under a variety of different climate projections. They focused primarily on a future where global average warming reached 3 degrees Celsius above pre-industrial levels by 2100: a not-quite-worst-caseto meet without aggressive actions to limit greenhouse gas emissions or other drastic solutions.In the U.S.
climate change will dramatically alter the way that many cities experience the seasons. In southern states where summer temperatures are already very high, many areas have plenty of infrastructure to help people cool off, such as air-conditioning. But as these same temperatures become commonplace in the Northern U.S., poorly prepared cities are expected to see many more deaths, the authors say.

First US study of nest temperature impacts on leatherback hatchlingsOne of the most unique of all sea turtle species, the leatherback (Dermochelys coriacea), is distinguished by its smooth, 'leathery' looking carapace or shell. Listed as vulnerable, this species is experiencing population declines from natural and anthropogenic threats—including climate change.

First U.S. study of nest temperature impacts on leatherback hatchlingsA study shows nest temperatures affect leatherback hatchling shape, performance and nest success. Lower temperatures produced longer hatchlings; highest temperatures produced hatchlings with thicker body depths. Hatchlings from the highest nest temperatures had shorter flippers. Righting response (ability to flip over) scores were significantly lower in hatchlings from hotter nests. Hatchlings that were smaller and/or had a larger body depth struggled to right themselves. The leatherback turtle nests in this study also had an overall lower hatching success (45 percent) than loggerhead (73 percent) and green sea turtles (70 percent).
