 Dear colleagues,
 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'
 press releases
 resources
 live web- and video-conferences
 stories from the Arctic and Antarctic
 Please contact Rhian Salmon (ipy.ras@gmail.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.
 To stay in touch with updates and activities, please subscribe to the  IPY open discussion space and announcements at:
  best wishes
 Rhian
