Global temperature rise and extreme weather events

Global temperatures are rising, with predictions suggesting a high of +1.7°C this year, an increase from +1.2°C five years prior. This warming is being compounded by a record El Niño event, with Pacific waters reaching temperatures nearly 3°C above normal. This phenomenon is expected to peak between August and October 2026.

These conditions have triggered extreme weather patterns globally. Regions such as Africa, Central Asia, and Southern Europe have faced torrential rains and flooding, while the Indian subcontinent, Central America, the Caribbean, and Southern Australia have experienced severe droughts. Other notable events include the first hurricane to strike Hawaii in 34 years and widespread fires across the Mediterranean. These extremes have resulted in thousands of excess deaths.

Research has also identified physiological impacts of these temperature increases. A study from Zhejiang University suggests that heat wave exposure and thermal stress may disrupt metabolic homeostasis, potentially accelerating biological aging and increasing risks for chronic diseases and mortality.

Socially, there is a noted shift in climate change denialism, where some individuals are moving toward a position of resignation, arguing the situation is too late to rectify.
