Drilling Back to the Future: Climate Clues from Ancient Ice on Greenland
Just before the last Ice Age, temperatures were 5 to 9 degrees F warmer than today, and global sea level was 13 to 20 feet higher. In July 2009, Climate Central traveled to Greenland to visit scientists drilling into ancient ice for clues about this chapter of the past, and what it might say about the potential effects of global warming this century.
Greenland: Ice Cores and Climate
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.
Georgia: Coal and Carbon
Coal generates carbon dioxide when combusted, which is causing the world to warm. In Georgia, a state that gets over 60 percent of its electricity from coal, some coastal residents are connecting the dots between coal and changes in the local ecology and economy attributed to global warming. Recognizing the need to reduce carbon dioxide emissions, engineers are exploring "clean coal" technology. What is this technology? Will it work?
