Understanding Climate is the theme of NASA’s Earth Science Week 2009 (ESW09), October 11-18, focusing on the connection between climate change and our oceans. A series of five short educational videos, entitled “Tides of Change”, focuses on the ocean-climate connection. Each educational video features a specific aspect of this connection, such as the water cycle or life in the ocean, and includes custom animation, data visualization and expert interviews. Watch the videos. NASA’s Global Climate Change website hosts a wealth of ESW09 content, including the interactive 3-D Eyes on Earth. This application allows users to fly around the planet on the wings of a satellite, observing the planet’s vital signs from space. The Climate site is also a one-stop shop for all of NASA’s best Earth science education resources related to the understanding of climate. One of the highlights of Earth Science Week is alive educational webcast on October 14 at 1:00 p.m. EDT. Classrooms around the country will participate in this live event focused on Earth science discoveries and careers. NASA oceanographers will discuss their careers, illustrate NASA’s unique view of the oceans from space, and answer questions submitted by participants.
