The ice storm beginning Friday evening created treacherous driving conditions across Iowa and eastern Nebraska Friday and into Saturday and prompted temporary closures of Interstate 80 after numerous cars and trucks slid off the road. In upstate New York, more than 33 inches (84 centimeters) was reported near Orchard Park, which is often a landing point for lake-effect snow.

Iran's capital and outlying provinces have faced rolling power blackouts for weeks in October and November, with electricity cuts disrupting people's lives and businesses. And while several factors are likely involved, some suspect cryptocurrency mining has played a role in the outages.

U.S. wildlife officials announced a decision Tuesday to extend federal protections to monarch butterflies after years of warnings from environmentalists that populations are shrinking and the beloved pollinator may not survive climate change.

For the third straight year, efforts to fight climate change haven't lowered projections for how hot the world is likely to get — even as countries gather for another round of talks to curb warming, according to an analysis Thursday.

At the United Nations climate talks, hosted in Baku, Azerbaijan, nations are trying to set new targets to cut emissions of heat-trapping gases and figure out how much rich nations will pay to help the world with that task.
