नेपाल सम्वत् ११४५ तछलाथ्वः ४ (जेठ १६, २०८२ ) मे ३०, २०२५ ,शुक्रबार, बाँपीझ्याला । From May 2024 to May 2025, nearly half of the world's population—around 4 billion people—experienced at least one additional month of extreme heat attributed to human-caused climate change. According to an analysis by World Weather Attribution, Climate Central, and the Red Cross, this surge in high temperatures led to illness, death, agricultural losses, and overwhelmed energy and healthcare systems. While floods and storms often capture media attention, the report emphasized that heat is the deadliest form of extreme weather, often underreported due to misclassification as other health issues like heart or kidney failure.

Caribbean nations, particularly Puerto Rico, were disproportionately affected, enduring far more extreme heat days than would have occurred in a world without climate change. Residents faced serious disruptions to daily life, with outdoor activities becoming unsafe and power outages worsening the situation. Charlotte Gossett Navarro from the Hispanic Federation shared personal experiences of heat-related illness and challenges caused by Puerto Rico’s unreliable power grid. For those with medical conditions, the intense heat without adequate cooling options becomes life-threatening.

Experts like Friederike Otto from Imperial College London warn that heat waves are "silent killers," often claiming lives quietly in homes or hospitals, especially among low-income populations, the elderly, and those with chronic health conditions. The report identified specific extreme heat events in Central Asia, South Sudan, and the Mediterranean that would not have been possible without climate change. In Morocco, for instance, at least 21 deaths occurred after temperatures soared to 118°F (48°C). Many people recognize the heat but remain unaware of its direct connection to climate change, according to Roop Singh from the Red Cross Red Crescent Climate Centre.

In response, cities around the world are beginning to implement strategies to mitigate extreme heat, such as heat action plans, tree-planting programs, and improved urban infrastructure. A notable example is Marseille, France, where city planners aim to expand shaded areas through reforestation. Despite these efforts, scientists stress that such adaptations alone are not enough. Without a global commitment to phase out fossil fuels, the frequency and intensity of heat waves will continue to rise, eventually outpacing the effectiveness of even the best-prepared heat resilience strategies.
