Central Asia Endures Record-Breaking March Heatwave Attributed to Climate Change
Central Asia experienced an unprecedented heatwave in March 2025, with temperatures soaring to levels typically seen in late spring or summer. According to a new study by World Weather Attribution (WWA), cities across Uzbekistan, Kazakhstan, Kyrgyzstan, and Turkmenistan recorded daytime highs near or above 30°C, far above the seasonal norm. In Kyrgyzstan's Jalalabad, the temperature peaked at 30.8°C, while Uzbekistan's Namangan and Fergana registered 29.4°C and 29.1°C, respectively. Kazakhstan’s Shahdara witnessed a nighttime low of 18.3°C, the hottest March night ever recorded in the country. Researchers from the Netherlands, Sweden, Denmark, the United States, and the United Kingdom examined the five hottest days and nights in March across the region. Their findings indicate that human-induced climate change made the heatwave approximately 4°C hotter and nearly three times more likely. They also noted that climate models tend to underestimate early-season heat, particularly in March. Economic and Agricultural Risks The timing of the heatwave posed serious challenges for agriculture. In Kazakhstan, the spike in temperatures coincided with the start of spring wheat planting, while in neighboring countries, fruit trees were already in bloom, raising concerns about yield losses. Agriculture remains a critical sector in the region, employing up to 50% of the workforce in some countries and contributing between 5% and 24% to GDP. The region also depends heavily on glacier-fed irrigation systems. Unseasonably warm weather can accelerate snowmelt, depleting water reserves needed during peak agricultural demand later in the season. In response to declining glacier volumes, seven artificial glaciers were built in southern Kyrgyzstan's Batken region in late autumn 2024 to support future water needs. A Warming Future The WWA study warns that without significant emissions reductions, such heatwaves will become increasingly frequent and intense. If global warming reaches 2.6°C, events like March 2025 could become far more common. Governments in Central Asia are beginning to take action. Kazakhstan and Tajikistan, for example, have integrated heat-related risks into their national climate adaptation plans. Still, experts urge a broader, more coordinated regional response, calling for the use of heat-tolerant crops, enhanced early warning systems, and climate-conscious urban planning.
