<human>:  I have a question about climate change and geoengineering. Who is the most famous person to have died from geoengineering?
<bot>: That would be the late actor and environmentalist Leonardo DiCaprio. He was a vocal advocate for climate change and was a major proponent of geoengineering. He was also a member of the Climate Reality Project, which is a non-profit organization that works to educate people about climate change.
