As global temperatures rise, proper hydration is crucial. Sweating is a key cooling mechanism, and thirst is not always a reliable indicator of water loss. Drinking water regularly can prevent dehydration, with severe consequences including impaired cognitive function, physical performance, and even life-threatening effects.
A study linking 11,862 koala hospitalisations in NSW to weather records from 2000-2022 found koala hospitalisations/death rates increased 1.5-3.5 times when 7-day average temps exceeded 30°C, with inland populations most vulnerable due to hotter conditions, exacerbated by climate change, habitat fragmentation, and disease.
Britain is set for a dramatic temperature rise, with highs of 26°C predicted for Friday after a cold May. The Met Office forecasts settled sunshine and warmer weather for the bank holiday weekend, particularly in England and Wales.
Environmental think-tank Envirocatalyst's satellite analysis of 247 Delhi municipal wards from 2015-2026 shows the city's mean land surface temperature rose from 29.1°C to 32°C, a 2.8-degree increase. March 2026 marks the first time in the 11-year record that all 247 wards simultaneously crossed the 26°C moderate heat stress threshold, leaving no ward at thermal rest. Sangam Vihar A recorded the steepest increase at 6.1 degrees, while some wards saw minimal rise of just 0.6 degrees.
