Humid heat is related to heat stress, occurring when environmental conditions overwhelm the body's ability to cool itself. Severe heat stress leads to an increase in the core body temperature of 3°C or more and can cause confusion, seizures, and loss of consciousness. If not treated promptly, severe heat stress can lead to muscle damage, major organ failure, and death.

Lead author of the study Dr. Lawrence Jackson, a Research Fellow in the School of Earth and Environment, said, "With climate change driving more frequent and intense humid heat events, particularly in tropical and subtropical regions, the risks to vulnerable populations and outdoor workers are increasing.

Co-author John Marsham, a Professor of Atmospheric Science in the School of Earth and Environment, added, "Our results focus on the daily timescale for these heat waves. An obvious next step would be to extend our analysis to hourly time scales which might allow us to work towards near real-time predictions with all the benefits that it would bring to vulnerable communities."

• Recently, Bangladesh successfully developed lotus silk — a biodegradable luxury fabric — using lotus stems, merging ancient tradition with modern sustainability science.
• Unlike conventional textiles, lotus silk is produced without water, chemicals or fossil fuels — making it one of the most eco-friendly fabrics in the world today.
• With high prices, lotus silk is attracting top fashion houses internationally, giving Bangladesh an opportunity to gain a premium place in the ethical fashion market.
• In some villages, lotus silk is creating new jobs for women who are now skilled in producing this high-value, global product; it’s reviving Bangladesh’s artisanal legacy.

• A resident population of blue whales has for many years lived in the coastal waters of Sri Lanka, but in recent years sightings of the animals have declined rapidly.
• With multiple pressures on these massive creatures — from ship traffic on one of the world’s busiest shipping lanes, to disturbance from whale tourism, pollution and surface sea temperature rise and climate change — there are several possible factors for the disappearance of the whales.
• Sri Lanka’s leading marine researchers agree that increasing sea temperatures in the North Indian Ocean, warming at the fastest rate of any of the world’s oceans, have likely pushed the whales to new waters.

• In southeastern Brazil’s Jequitinhonha Valley, a region that is home to up to 85% of the country’s known lithium deposits, residents say the arrival of the mining company Sigma Lithium brought new community conflicts and issues with their water supply.
• Some researchers say decisions concerning where and how to mine, as well as the types of consultation practices companies use, result in different levels of impact, but that there’s no way governments can ensure corporate responsibility.
• Local communities in the Jequitinhonha Valley have a blueprint on how companies can improve relations and mitigate impacts.
• Sigma Lithium did not respond to Mongabay’s request for a comment, but its website states its mission is to support the growth of the electric vehicle industry as a producer of sustainable lithium.
