Looking back at that bygone warm period in Earth's history could offer help in forecasting the impact of human-spurred climate change, researchers said of a review of hundreds of studies of ancient climate records published in the journal Science. Quickly acidifying seawater eats away at coral reefs, which provide habitat for other animals and plants, and makes it harder for mussels and oysters to form protective shells.

As Japanese officials consider whether and when to reactivate most of the country's 54 nuclear plants, a year after the Fukushima reactor disaster, they continue to face challenges to public confidence in the nuclear industry and its regulator.
