A team of scientists has successfully flown from the Arctic to the Antarctic this month, the first step in a three-year project to make the most extensive airborne measurements of carbon dioxide and other greenhouse gases to date.

While there has been much attention focused on the question of whether climate change influences hurricanes, scientists are also interested in whether the reverse holds true: do hurricanes significantly impact global climate?

New research by NCAR scientists uses atmospheric general circulation model experiments to explore how projected losses in Arctic sea ice may affect climate.

Researchers are working toward predictions of climate change impacts in specific regions and even metropolitan areas. But are local and regional decision makers taking advantage of this science to begin to prepare for the impacts of global warming?

Contrary to earlier projections, few developing countries will be able to afford more efficient technologies to reduce greenhouse gas emissions in the next few decades, new research concludes.
