Working as an Antarctic field scientist, I witnessed the destruction provoked by a rapidly warming planet. But I also found inspiration.

Scientists have spotted mature jellyfish under the Arctic sea ice, where they aren’t supposed to be.

The Arctic is warming twice as fast as the rest of the planet, and scientists are seeing the effects across ice and ecosystems. The average annual air temperature over Arctic land is now 3.5°C (6.5°F) warmer than it was 1900, Greenland is experiencing longer melting seasons, and this year’s spring snow cover extent set a record low in the North American Arctic, according to the National Oceanic and Atmospheric Administration’s newly released 2016 Arctic Report Card.

The Gordon and Betty Moore Foundation announced a $3.7 million grant to Columbia University's Lamont-Doherty Earth Observatory to support research that couples state-of-the-art geophysical observations from unmanned aerial systems with a community-engaged research approach to bridge scientific and indigenous understanding of sea ice change in the Alaskan Arctic.

Antarctic sea ice is constantly on the move as powerful winds blow it away from the coast and out toward the open ocean. A new study shows how that ice migration may be more important for the global ocean circulation than anyone realized.

A snapshot of the changing climate of the West Antarctica Peninsula, where the impact of fast-rising temperatures provides clues about future ecosystem changes elsewhere.

Climate change has become fertile ground for both scientists and artists, with its potential to reshape landscapes as well as human civilization itself.
Two women investigating climate change from different perspectives—Christine McCarthy, a geophysicist at Lamont-Doherty Earth Observatory, and Denise Iris, a multimedia artist from Brooklyn—had a chance to spend several days together recently. In the Rock Mechanics Lab at Lamont, where McCarthy works, and a nearby “cold room” chilled to the climate of an industrial freezer, they exchanged notes on two ways of looking at ice.

Tiny one-celled organisms called radiolaria are ubiquitous in the oceans, but various species prefer distinct habitats. Thus it aroused considerable intrigue in 2012 when protozoa specialist O. Roger Anderson and colleagues published a study showing that radiolaria normally found near the equator were suddenly floating around in arctic waters above Norway. Was this a sign that global climate change was bringing an invasion of warm-weather plankton?

Scientists still puzzle over how Earth emerged from its last ice age, an event that ushered in a warmer climate and the birth of human civilization. In the geological blink of an eye, ice sheets in the northern hemisphere began to collapse and warming spread quickly to the south. Most scientists say that the trigger...
