With climate change causing temperatures to rise across the globe, extreme heat is becoming more and more of a health threat. The human body is resilient, but it can only handle so much. So what is the highest temperature people can endure? The answer is straightforward: a wet-bulb temperature of 95 degrees Fahrenheit (35 degrees Celsius), according to a 2020 study in the journal Science Advances . Wet-bulb temperature is not the same as the air temperature you might see reported by your local forecaster or favorite weather app. Rather, a wet-bulb temperature is measured by a thermometer covered in a water-soaked cloth, and it takes into account both heat and humidity. The latter is important because with more water in the air, it's harder for sweat to evaporate off the body and cool a person down. If the humidity is low but the temperature is high, or vice versa, the wet-bulb temperature probably won't near the human body's tipping point, said Colin Raymond, a … [Read more...] about What’s the hottest temperature the human body can endure?

Between November 1936 and November 1937, H.G. Wells gave a series of lectures in Great Britain, France, and the US about the world’s impending problems and how to solve them.

MIT Press has just issued a compendium of these lectures , along with related material Wells presented as magazine articles and radio addresses. The collection also includes a foreword by the science fiction writer Bruce Sterling and an introduction by Joseph Reagle, an associate professor of communication studies at Northeastern who writes and teaches about popular culture , digital communication , and online communities .

During a summer of deadly heatwaves, Democratic senators are pressing for a bigger federal response to the danger posed by extreme heat. Senators Ed Markey (D-MA), Alex Padilla (D-CA), and Cory Booker (D-NJ) reintroduced the Preventing Heat Illness and Deaths Act today. Representative Charlie Crist (D-FL) will introduce similar legislation in the US House of Representatives. They are pushing for its measures to be included in either the bipartisan infrastructure or budget reconciliation package that Democrats are scrambling to advance. “We’ve heard that extreme heat is among the White House priorities in the climate space, and I am fighting to include provisions of my bill,” Markey said in an email to The Verge . The bill would create the first federal financial assistance program to fund community-based projects that are specifically focused on extreme heat, according to Markey. It would also formalize and expand the National Integrated Heat Health Information System … [Read more...] about Extreme heat is on Democrats’ infrastructure agenda
