Artists for Climate

Artists for Climate is an open call for digital illustrations, graphic design, lettering art and typography by TED Countdown, in collaboration with Fine Acts. The initiative sought awe-inspiring designs that depict a hopeful future around climate change, or have a clear message around the urgency for actionable change.



DearTomorrow is an award-winning climate storytelling project where people write messages to loved ones living in the future. Messages are shared at deartomorrow.org and through social media, public talks, community events, and public art to inspire deep thinking and bold action on climate.
