Climate change research using oldest ice records featured in TVO series
Research by Biology Professor Sapna Sharma was featured in TVO’s Climate Watch Shorts in the video “The Record Keepers.”
In 2016, Sharma published a study in Nature Scientific Reports that used centuries-old ice data to reveal increasing trends towards later ice-cover formation and earlier spring thaw since the start of the Industrial Revolution. These data date back to the 1400s in Japan, where Shinto priests in Japan began keeping records of the freeze dates of a nearby lake, and to the 1600s in Finland, where merchants started recording breakup dates on a local river. Together they create the oldest inland water ice records in human history and mark the first inklings of climate change.
“The Record Keepers” explores the story behind the data from Japan and how Sharma used them to study climate change. To watch the video, visit http://tvo.org/article/current-affairs/climate-watch/climate-watch-shorts-how-an-unpredictable-climate-is-changing-life-in-ontario
