Topography and Microclimate Shape Tree Ring Growth
Wizened bristlecone pines in California reveal past climate trends, and new research shows how slight variations in landscape position drive different growth patterns in trees’ annual rings.
Penguin Poop Keeps a Record of Antarctic Glaciation
Scientists are digging up Adélie penguin guano to study millennia of Antarctica’s history.
Neanderthals Likely Ate Rotten Meat
Neanderthals have long been painted as meat-eating machines. But could a new look at a dietary proxy and how it changes when meat rots uncover insights into what these extinct hominids really ate?
Using Microbes to Predict the Flow of Arctic Rivers
Bacterial DNA provides a good estimate of river discharge.
Radiocarbon in the Oceans
Offsets in radiocarbon concentration within the ocean or between the ocean and the atmosphere are particularly useful proxies for a variety of studies.
Tree Rings Tell a Tale of Wartime Privations
In occupied Norway during World War II, the German navy deployed thick chemical fog to protect a precious battleship. The effects are still detectable in trees.

Five Weird Archives That Scientists Use to Study Past Climates
When tree rings, ice cores, and cave formations can’t cut it, try your luck with whale earwax or bat poop.
One of World’s Oldest Animals Records Ocean Climate Change
Researchers probe millennia-old deep-ocean sponges for links between ocean nutrients and climate.
