The World Meteorological Organization warned that the world will likely experience its worst heat on record within the next five years [1].

This projection signals a critical escalation in climate instability, as the planet surpasses internationally recognized safety limits and faces unprecedented regional heat risks.

According to the WMO, there is an 86% probability that at least one year between 2025 and 2029 will have a higher temperature than 2024 [1]. The year 2024 was the hottest on record [1]. Regional forecasts are even more severe, with a 92% probability that East Asia will exceed 2024 temperatures during this five-year window [1]. South Korea faces a 68% probability of surpassing those same record levels [1].

The organization reported that the global average temperature is now 1.55 °C above pre-industrial levels [1]. This means the 1.5 °C safety threshold has been breached [1].

Certain regions are warming significantly faster than the global average. The Arctic is warming 3.5 times faster [1]. On the Korean Peninsula, temperatures have risen 1.48 °C, which is about twice the global rate of warming [1].

These trends are further complicated by cyclical weather patterns. The WMO noted that an El Niño was expected by the end of 2024 [1].

"The World Meteorological Organization, WMO, predicted that the worst heat in history will hit within the next five years," a YTN anchor said [1].

“The global average temperature is now 1.55 °C above pre‑industrial levels.”

The breach of the 1.5 °C threshold marks a transition from theoretical climate warnings to an active breach of a global safety benchmark. The disparity in warming rates, particularly in the Arctic and the Korean Peninsula, suggests that regional ecosystems and infrastructure will face stress far more rapidly than global averages imply, increasing the urgency for localized adaptation strategies.
