The Facts

A World Meteorological Organization (WMO) report released Wednesday found that Asia's 2025 mean temperature was 0.96°C above the 1991–2020 average, ranking between the second- and fourth-warmest years on record. The region has warmed nearly twice as fast during 1991–2025 as it did during 1961–1990.

Japan, China and South Korea each recorded their hottest summer on record in 2025, while Kazakhstan saw temperatures up to 14°C above normal and Bahrain logged ten consecutive days above 40°C (104°F). Hot, dry and windy conditions fueled the largest wildfires ever recorded in South Korea.

Monsoon flooding in Pakistan killed more than 1,000 people and left over three million people requiring assistance in 2025. In Vietnam, flooding linked to multiple weather systems caused at least 200 deaths and an estimated $1.9 billion in economic losses.

Tropical Cyclone Ditwah delivered roughly 10% of Sri Lanka's typical annual rainfall within 24 hours, resulting in more than 640 deaths, displacing over 200,000 people and causing economic losses estimated at around 4% of gross domestic product (GDP).

All 23 monitored glaciers in High Mountain Asia lost mass during the 2025 glaciological year due to above-average temperatures and below-average winter snow. The region, centered on the Tibetan Plateau, holds the largest ice volume outside the polar regions, covering approximately 100,000 square kilometers (38,610 square miles).

Ocean heat content across Asia reached a new record in 2025, as marine heatwaves affected more than 10 million square kilometers between July and September. Sea levels in the region also reached their highest level since satellite monitoring began in 1999, with rates along the Indian coast reaching about 4.9 mm per year.

Climate-concerned narrative

Asia's climate crisis is accelerating at a terrifying pace — every single monitored glacier in High Mountain Asia lost mass, ocean heat hit record levels. Japan, China and South Korea all logged their hottest summers ever, while Pakistan's flooding killed over 1,000 people. The data is undeniable: warming is outpacing preparedness across the entire region.

Climate-skeptic narrative

Alarm over Asia's heat and sea levels ignores the fact that El Niño is a natural, ancient cycle of ocean heat redistribution. Seas have been rising since glaciers melted 12,000 years ago, and current rates are a modest 8-9 inches (20-23 cm) per century. Treating routine natural variability as an unprecedented crisis fuels needless panic rather than evidence-based policy.
