Core libraries store a treasure trove of data about the planet鈥檚 past. What will it take to sustain their future?

With a changing climate, fires in far northern forests that smolder throughout winter and erupt again in spring could become more common.

"Zombie fires" may sound like something straight out of science fiction, but they're a real phenomenon that is likely to become more common in the area ringing the Arctic, and possibly the Arctic itself, as climate change continues, a new study finds. Merritt Turetsky comments on the study and explains its context.

Food insecurity is a growing threat in many places around the world. This situation is exacerbated by two events that many geoscientists are tasked to study: natural hazards and our changing climate. The February issue of Eos, organized by Ben Zaitchik and Merritt Turetsky, looks at how geoscientists are using their research to help create resilient communities around the world that can always be sure of food in their pantries.

Widespread wildfires in the far north aren鈥檛 just bigger; they鈥檙e different鈥攚ith strong consequences for the global climate鈥攚arn international fire scientists in a commentary published today in Nature Geoscience.

Alaska is getting wetter. A new study spells out what that means for the permafrost that underlies about 85% of the state, and the consequences for Earth鈥檚 global climate.

Merritt Turetsky is quoted in a Washington Post story on the record-setting heat wave across Siberia that is leading to massive wildfires and permafrost melt.

A historic heat wave is occurring in the Arctic, already the fastest-warming place on Earth due to the increasing accumulation of greenhouse gases. Dr. Merritt Turetsky has studied the Arctic for decades. She joins William Brangham on PBS NewsHour to discuss causes and consequences of the Arctic's rising temperatures.
