Core libraries store a treasure trove of data about the planet’s past. What will it take to sustain their future?
paleoclimatology & paleoceanography
An Ancient Meltwater Pulse Raised Sea Levels by 18 Meters
Meltwater pulse 1A, a period of rapid sea level rise after the last deglaciation, was powered by melting ice from North America and Scandinavia, according to new research.
Carbonate Standards Ensure Better Paleothermometers
A community effort finds that carbonate standards eliminate the interlaboratory differences plaguing carbonate clumped-isotope thermometry studies.
Narwhal Tusks Record Changes in the Marine Arctic
This new paleorecord can help scientists better understand how climate change and human activity are changing marine mammals’ environments and habits.
Timing of Earth’s Oxygenation May Need a 100-Million-Year Revision
A new study revises estimates for when oxygen became a permanent part of the atmosphere and solves a puzzle about glaciation during the Paleoproterozoic era.
An Unbroken Record of Climate During the Age of Dinosaurs
A scientific drilling project in China has retrieved a continuous history of conditions from Earth’s most recent “greenhouse” period that may offer insights about future climate scenarios.
New Spherical Cap Field Model for Europe and Direct Environs
New data on ancient burnt structures is integrated into a superior spherical cap field model for Europe.
South Pole Ice Core Reveals History of Antarctic Sea Ice
Every summer, most of the sea ice near Antarctica melts away, but its saltiness leaves a permanent record that scientists can trace back for millennia.
Holy Water: Miracle Accounts and Proxy Data Tell a Climate Story
In 6th century Italy, saints were said to perform an unusual number of water miracles. Paleoclimatological data from a stalagmite may reveal why.
Chicxulub Impact Changed Tropical Rain Forest Biodiversity Forever
Sixty-six million years ago, an asteroid reset most of life on Earth. But without this catastrophic event, the composition of neotropical rain forests wouldn’t be the same.
