In July of 2009, Climate Central senior research scientist Heidi Cullen traveled to Greenland with a production team from StormCenter Communications to visit the North Greenland Eemian Ice Drilling Project, or NEEM. Scientists from 14 nations gather together each summer in northern Greenland, where they work to drill a core of solid ice, looking into the past for clues to future climate change.
The NEEM scientists are focused on a period known as the Eemian, which began about 130,000 years ago and lasted about 10,000 years. During the Eemian, temperatures were between 5 and 9 degrees F warmer than today, and global sea level was 13 to 20 feet higher. Under many climate change scenarios, global temperatures are projected to warm a similar amount this century, so understanding the climate of the Eemian could teach us more about the potential effects of warming today.
To study past climate, the scientists rely, in part, on information trapped inside tiny bubbles in the ice. These bubbles…

An international team of climate scientists, working on the NEEM research project, has just completed their first season toward drilling a 1.6-mile deep vertical core of solid ice in Greenland, looking for clues about ancient and future climates. In July of 2009, Dr. Heidi Cullen traveled to Greenland with a production team from StormCenter Communications to visit the team, and discuss their findings.
For a more in-depth look at the NEEM project and its findings, watch Drilling Back to the Future: Climate Clues from Ancient Ice on Greenland, Climate Central's report broadcast on PBS’s The NewsHour.

The Air Force National Guard is a vital part of climate research in the far north of Greenland. Dr. Heidi Cullen, with a production team from StormCenter Communications, met with the pilots of the 109th Airlift Wing to talk about what it’s like to fly in extreme weather conditions, and their dangerous job — getting people and equipment into Greenland's harsh interior and back.

Greenland is covered in so much ice that if it all melted, it would raise sea level around the world by 23 feet. While it's not all melting, scientists say that climate change is turning a lot of that ice to water. But, how do we know?
Two GRACE (Gravity Recovery and Climate Experiment) satellites that orbit the Earth in tandem were launched in March 2002 by NASA. The pair measure the distance separating each other to an accuracy of 1 percent of the width of a human hair — and they orbit as far apart as Washington, DC and Philadelphia. Because each satellite accelerates or decelerates depending on the mass of the area beneath it (for example, a massive mountain range vs. flat lowlands), and because one satellite trails the other at some distance, the record of the shifting distance between them can be read like a giant planetary scale. And since they orbit over the same areas every ten days, the GRACE satellites provide a detailed record of mass changes in time, even tracking the seasonal…
These videos, graphics and animations digest information from countless satellite and submarine measurements, developing a picture of change in the Arctic as it has warmed. See the miles-high view — and what’s happening from underneath, too.
Just think about it… What if you were trapped under something heavy and the mouse was out of your reach? Scary, right? That's exactly why we have these keyboard shortcuts so you can still use Vimeo until the help arrives.
