The phrases "global warming" and "climate change" are technically different, but the way most people use them - including lots of climate scientists - they mean pretty much the same thing.
When scientists look at climate variations in the past, they don't see anything like today's warming.
It's why global warming is happening, and why scientists are so worried about rising levels of carbon dioxide and other gases generated by agriculture, transportation and industry
Just before the last Ice Age, temperatures were 5 to 9° 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.
Accompanied by a production team from StormCenter Communications, Dr. Heidi Cullen spent some time with an international team of scientists that just wrapped up their first season toward drilling a 1.6-mile core of solid ice in Greenland to find out what life is like in this remote place.
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.
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.
Wildfires are on the rise in the State of Washington, as they are in much of the American West and climate change looks at least partly responsible.
