A dozen different species in interstellar dust particles that formed the solar system have evolved to more than 4500 species today. Previous work from…

NASA sees first Atlantic hurricane fizzling in cool waters

Sea surface temperatures play a big role in keeping a tropical cyclone alive. They need warm seas of at least 300 Kelvin (80 Fahrenheit/26.8 Celsius) to…

Significant sea-level rise in a 2-degree warming world

Even if global warming is limited to 2 degrees Celsius, global-mean sea level could continue to rise, reaching between 1.5 and 4 metres above present-day…

Elephant seals help uncover slower-than-expected Antarctic melting

A team of scientists have drilled holes through an Antarctic ice shelf, the Fimbul Ice Shelf, to gather the first direct measurements regarding melting of the…

Remote Siberian Lake Holds Clues to Arctic–and Antarctic–Climate Change
