Sediments Offer an Extended History of Fast Ice
Scientists used sediments to create a millennia-long archive of Antarctic fast ice. Along the way, they discovered that the freezing and thawing of this enigmatic ice appear to be linked to solar cycles.
How the Spring Thaw Influences Arsenic Levels in Lakes
Four lakes near Yellowknife, Canada, show that there’s no one-size-fits-all answer.
Hundreds of Scientists “Vehemently Oppose” U.S. Effort to Purchase Greenland
More than 200 scientists scientists have signed a letter condemning U.S. President Donald Trump’s efforts to acquire Greenland.
Successful Liquid Lake Conditions in a Cold Martian Paleoclimate
Simulations from a new lake model explain how liquid water could have been maintained over Mars in a cold climate, thus resolving a critical scientific gap in our understanding of Mars’ early history.
Could Future Mars Habitats Be Made of Ice?
Models suggest that clear ice, sourced and distilled on Mars, could offer a feasible alternative for building stable off-world structures.
Changing Winters Leave Indigenous Alaskans on Thin Ice
Researchers are blending Indigenous Knowledges with climate models to describe shifts in snow and ice.
New Lessons from Old Ice: How We Understand Past (and Future) Heating
Fragments of blue ice up to 6 million years old—the oldest ever found—offer key insights into Earth’s warming cycles. Researchers are using these ancient data to refine models of our future climate.
Maybe That’s Not Liquid Water on Mars After All
A “very large roll” of a radar instrument offers new insight into a highly reflective area near the Martian south pole.
