Some time ago Eli pointed to a paper by Steven Sherwood and Matthew Huber which described the the limit of human survival on this planet because if wet bulb temperatures go beyond 35 C, humans simply fall over and die of heat stroke. Given our behavior, death, doom and disaster are saddling up and while they might not arrive across the entire planet before a couple of hundred years as an Anonymouse said, local excursions could wipe out large, well populated, nuclear armed regions, and those people would vote with their feet and their weapons.
As with much of climate change information, people just don't want to hear doom and gloom. Coby Beck, from whom Eli "borrows" this video, has found the proper way of explaining
The video has a useful disclaimer
Justin is expressing what scientists discuss around the very, very worst case scenarios for climate change. He is in no way suggesting that these things are 100% definitely going to happen, merely pointing out that these are legitimate possibilities that scientists seriously discuss.
The purpose of this video is to provoke discussion and engagement through highlighting aspects of the scientific discussion that are often glossed over for fear of disengaging a weary public. We believe its important for the community to realise exactly what the worst case scenarios considered are, because after all, the decision to act is ultimately in their hands.Eli, OTOH, thinks that much of this will happen locally in some exceedingly inconvenient places within the next 10-15 years.
