For your weekend viewing pleasure: Media-based developer and data scientist Neil Halloran has just released a documentary about understanding scientists’ claims about climate change, three years in the making.

The animated documentary, “Degrees of Uncertainty,” debuted last week — aptly, on Earth Day — and dives into how society has come to learn about climate change and the processes scientists have taken to learn it themselves. The 24-minute documentary explores how journalists and the public learn and talk about climate change and takes a stab at the question, “How sure are climate scientists?”

Halloran previously released a series called “The Shadow Peace,” exploring nuclear war and peace, the sequel to his viral “The Fallen of World War II.”

Halloran also previously owned and worked on a film company, Higher Media, along with his brother Mark, but now works through his own company. Halloran said he receives help from remote researchers and London-based musician Andy Dollerson.

“I also make a point to get lots of feedback through the process, which was especially important for a topic as thorny as this,” Halloran told

The docs are created by hand using custom software, he said — “I suppose it’s a mix of filmmaking and creative coding which [is] a very laborious process.”

This film in particular took three years to make, and Halloran said he plans to work more with outside animators for future projects so that he can produce films more frequently.
