The next quarterly IPY Science Day, or International Polar Day, will occur on March 12th, 2008, and focus on Changing Earth; Past, Present, and Future.
The polar region are critical archives of polar change. Different techniques and disciplines are used to learn about Earth's history over millions, thousands, and hundreds of years. Observations monitor and explore the Earth today, and models developed from these sciences help predict the future. By learning more about the Earth in the past, and how climates have changed previously, we equip ourselves to better predict and understand changes we are experiencing today, and will experience in the future.
The IPY Science Day on March 12th will focus on change over geological time, especially the glacial and interglacial periods that have occurred during the past million years, and cycles of ocean- atmosphere interactions that give rise to regional climate variations on scales of decades to centuries. Understanding these processes, and the science projects that investigate them, is critical in order to put recent human- induced climate change into context.
During the next few weeks we are coordinating a number of events, activities, and resources around the theme of Changing Earth. This includes
background information about the science
contacts and information about relevant IPY projects and scientists
multi-lingual educational activities
community 'virtual balloon launch'
live web- and video-conferences
stories from the Arctic and Antarctic
Please contact Rhian Salmon (email@example.com) if you would like to get involved in this event, or share a resource, activity, or area of expertise.
Please also circulate this information around your networks, and encourage wide involvement in this event across a range of educators, communicators, and media.
