Glaciers: A Chronology of Climate Change is a CRPA project that seeks to explain the historical cycling of glaciers in the context of climate change. By using chemical isotopes (Beryllium 10), the age of rocks that have been covered with glacier ice and exposed to sunlight later can be determined fairly accurately. Through this method, the glaciation cycles have been determined for the last 70,000 years. In collaboration between the Lamont-Doherty Earth Observatory at Columbia University and the American Museum of Natural History (AMNH), this project is designed to impact adult audiences, youth in grades 6th-12th, and teachers writ large.The research results shall be expressed via an eight-minute high definition film for large screen viewing in the "Science Bulletins" section of the AMNH and the affiliated museums. A rigorous front-end evaluation will be used to inform the presentation and assess audience impact. Subsequent formative evaluations are designed to measure the learning impact of the film and the retention of longer term concepts.It is anticipated that more than 700,000 individuals will have access to current, scientifically accurate data and related information on glaciation cycles and climate change through the educational film and website. Materials will be easily accessible to teachers and the film will be closed captioned in both English and Spanish.

《冰川：气候变化年表》是CRPA的一个项目，旨在解释气候变化背景下冰川的历史循环。通过使用化学同位素（B10），可以相当准确地确定被冰川冰覆盖并随后暴露在阳光下的岩石的年龄。通过这种方法，已经确定了过去70，000年的冰川周期。该项目由哥伦比亚大学的拉蒙特-多尔蒂地球观测站和美国自然历史博物馆（AMNH）合作，旨在影响成年观众、6 - 12年级的青少年和广大教师。研究结果将通过AMNH和附属博物馆的“科学通报”部分的大屏幕观看的8分钟高清电影来表达。将使用严格的前端评估为演示文稿提供信息，并评估受众影响。随后的形成性评价旨在衡量电影的学习影响和长期概念的保留情况，预计70多万人将通过教育电影和网站获得关于冰川周期和气候变化的最新、科学上准确的数据和相关信息。教师将很容易获得材料，电影将有英文和西班牙文字幕。
