Climate and the Opal Artisans of the Sea
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…

3 Reports Bring a Wake-Up Call: Change the Conversation
Three scientific reports echo the message that climate change and its impacts are here and now, with more to come. So how to change the conversation to reach beyond the already informed and connect to a much larger population?

Diminishing Ice Intensifies Spotlight on Arctic
As the arctic region loses ice in a changing climate, the economic and social tradeoffs are unclear. How will we balance economic, social and environmental functions? The Center on Global Energy Policy and the Consulate General of Canada in New York will examine these questions in a discussion on March 26: “Understanding the Arctic Resource…

Explore the Arctic Ocean With ‘IceTracker’
This week, we are launching a test of “IceTracker”—a tool that allows users to see the trajectories of Arctic sea ice forward or backward from any day between 1981 and 2012, as well as sea-ice speed, air temperature, water depth and the age of the sea ice.

The Arctic’s Secret Garden
Lamont-Doherty Earth Observatory marine biologists Craig Aumack and Andy Juhl spend a month each spring in Barrow studying the algae dwelling in and under the sea ice. Their goal is to learn more about the different species of algae that compose these communities and their role in the Arctic marine food web.

Strange Bedfellows in the Climate Change Saga: Taiga to Tundra
In the nine-hour drive on the great Dalton Highway to Toolik Field Station one starts out in the boreal forest, which is also called the “taiga,” but the forest eventually disappears. More accurately, trees disappear. Leaving Fairbanks, one drives through beautiful stands of spruce, birch, and aspen trees, but as one gets closer and closer…

Strange Bedfellows in the Climate Change Saga: The Quest for the Arctic Wolf
When you travel northbound on Alaska’s famous Dalton Highway heading toward the Arctic Sea, the northern edge of the world, you carry a radio to communicate with the enormous rigs that roar along the road, the giant trucks made famous by the History Channel’s Ice Road Truckers. Radio messages between truckers and non-truckers are simple…
