This is a great data-driven short documentary by Neil Halloran about how smallpox was eradicated from the face of the Earth. And what it took was humanity, through the use of science & humanitarianism, answering its own plea for something to be done about it.
Some philosophers believe there was a secondary humanitarian revolution that followed the scientific revolution. And I note this because the eradication of smallpox also had these two phases. The scientific breakthroughs of inoculation and the vaccine allowed many countries to become virtually smallpox-free — but not all countries. In fact, those 300 to 500 million deaths in the 20th century? They came well after the vaccine had been discovered. So clearly, for much of the world, something more was needed than medical innovation. And fortunately there’s reason to think that these two types of progress might be connected.
Part of being a human is contemplating why some of us get so sick. It’s a practical question and it’s more than that. As we learned about disease, the theory goes that we began to think a little differently about those who fell ill — to see that their suffering truly wasn’t meant to be. We stepped away from thinking it was up to a higher power and into the belief that, well, it was up to us.
In his latest impeccably produced video, Neil Halloran looks at the science of climate change and uncertainty both in science and in the public’s trust of science.
Degrees of Uncertainty is an animated documentary about climate science, uncertainty, and knowing when to trust the experts. Using cinematic visualizations, the film travels through 20,000 years of natural temperature changes before highlighting the rapid warming of the last half century.
The vast majority of climate scientists seem pretty sure that human use of fossil fuels has warmed the Earth and that warming is increasingly having an impact on both nature and society. But how do we, as members of the public with a relatively poor understanding of science, evaluate how certain we should be?
FYI: This video includes some interactive elements that only work if you watch it on Halloran’s website.
Neil Halloran, creator of the excellent Fallen of World War II interactive visualization of the casualties of WWII, is working on a similar visualization about the possible effects of a global nuclear conflict. He recently uploaded an in-progress video of the project with a special 2016 election message at the end. Amazing and scary to see how much of a difference WWII made in the global death rate and how minuscule that would be in comparison to a global nuclear war.
