Climate change is a major theme that TED has been focusing on since 2020 as part of the TED Countdown, and it is a topic that has been discussed by the TEDx community around the world. Ideas on this theme are provided as video content. This time, we plan to conduct a 2-day hackathon on the theme of “Climate Change” to identify specific issues in this part of Hokkaido where we live, and come up with solutions to these issues, including software, ideas, plans, and proposals. We will then have an opportunity to present these results at a later date.
