Wet Bulb Global Temperatures Resources

Why are Wet Bulb Global Temperatures important? Heat stress and human safety Body's cooling mechanism : The body cools itself by sweating & evaporating that sweat. The wet bulb temperature is the key factor in how effective this process is. ☆ Dangerous conditions : When the wet bulb temperature gets too high, around 35°C or 95° F, it can be fatal because the body can no longer cool itself through sweating, even in the shade. ☆ Vulnerable populations : The elderly, young children, outdoor workers, homeless, and people with underlying health conditions are particularly at risk from high wet bulb temperatures.  ☆You Can Assess Your Risk with simple Low-Cost Tools Wet Bulb Temperature tools for everyday use, for everyone.  For under £30, a small battery-powered digital thermometer/datalogger with Bluetooth and a smartphone app can provide relative humidity in % & temperature in Degrees Celsius or Fahrenheit. The app can provide graphical output.  ...

Proff Hayley Fowler, National Emergency Briefing: Brief mention of Wet Bulb Temperatures in Pakistant, without using the term Wet Bulb Global Temperatures #nebriefing

Proff Hayley Fowler, National Emergency Briefing:  Severe weather is the new normal driven by Fossil Fuels use.  But mentioning Wet Bulb Temperature in Pakistan and suggesting that they will eventually get to us is not very honest.  Wet Bulb  Temperatures are a clear and present heatwave risk.

XReadiness Fails To Address Wet Bulb Temperatures (WBT) A Major Risk to Human Life

The Original XReadiness Document can be  downloaded here Emergency planning documents like this require guidance and leadership because they are being fed into a culture which doesn’t have any survival skills experience, and the current leadership within XR and the associated groups like Just Stop Oil, Climate Majority Project and the Green Party lack the expertise and experience to provide that leadership or understanding survivalism in depth. Preparedness coupled with survival skills sadly has a poor reputation for being dominated by right wing climate deniers stacking up their tinned food reserves and weapons while voting Reform and grifting on YouTube. XReadiness document should have been advertised as a cooperatively produced document, so that a wider group of more survival skilled and experienced activists could contribute and make it more relevant to the Climate Emergency and families wanting understand adaptation and climate risk. The XReadiness document starts from the pre...

The Wet Bulb Global Temperature Human Survival Threshold is NOT 35°C

Image
Why is the 35°C threshold being revised Health studies show lower limits : Experiments with healthy young adults have found that severe heat stress can occur at wet-bulb temperatures as low as 31.5°C. Experimental findings : In controlled experiments, critical wet-bulb temperatures for healthy young adults ranged from 25°C to 28°C in hot-dry environments and 30°Cto 31 °C in warm-humid environments. Lower limits for vulnerable groups : Research suggests that older adults have even lower survival limits, ranging from 21.9°C to 27.8°C Uncompensable heat stress : The point at which the body can no longer cool itself through sweating is reached at a lower wet-bulb temperature than the theoretical 35°C. Real-world events : Recent heatwaves have seen wet-bulb temperatures in the 31°C to 33.6°C range, demonstrating that these lower thresholds are being reached in the real world. Britain is surprisingly humid. Anyone who suspects that the above Wet Bulb Global Temperature Chart is o...

What are Wet Bulb Temperatures & Why They Are Climate Survival Essential Knowledge

  What are Wet Bulb Temperatures? Wet bulb temperature  measures the combined effect of heat and humidity, representing the lowest temperature achievable by evaporating water into the air .  It is measured using a thermometer with a water-soaked cloth over its bulb, and it always reads lower than or equal to the dry bulb temperature. A higher wet bulb temperature indicates higher humidity, which hinders evaporation and reduces the body's ability to cool itself through sweating. This makes it a critical metric for assessing heat stress on humans and is often higher than the commonly reported heat index. Why Wet Bulb Temperatures are important Humidity and Evaporation :  The wet bulb temperature is essentially a measure of how well water can evaporate into the air. Human Cooling : Our bodies cool through the evaporation of sweat. High wet bulb temperatures mean less evaporation, making it harder to cool down and leading to dangerous heat stress.   H...
