Bangladesh is once again confronting a familiar, but increasingly dangerous climate threat. The return of El Niño, combined with unprecedented global warming, is amplifying the risks of extreme heat, erratic rainfall, drought, and agricultural disruption. And not to mention, we are already witnessing it.
Although climatologists have suggested that Bangladesh may not experience the most severe impacts since this El Niño developed later in the year, but the warning signs are already evident�"and there is no room for complacency.
However, scientists have repeatedly stressed that every El Niño is different. What makes this one particularly alarming is that it is unfolding on a planet that is already warmer than ever before. Global temperatures have broken records in recent years, several European countries are manifestly bearing the brunt, and a large number of climate researchers now project that 2027 could become the hottest year ever recorded.
For Bangladesh, one of the world's most climate-vulnerable nations, this means higher temperatures, more frequent heatwaves, unpredictable monsoon rainfall, and growing pressure on water, food, and public health.
We acknowledge the fact that the effects are already being felt. Extended periods of intense heat have disrupted daily life, increased heat-related illnesses while reduced labour productivity. Throughout the country, rainfall has become increasingly erratic, threatening crop yields and exposing farmers to greater uncertainty. Lower river flows are also triggeringgrowing salinity in the coastal belt, endangering freshwater supplies and agriculture. These challenges are already adding up to the country's existing vulnerabilities, including cyclones, river erosion, flooding, and rising sea levels.
Much to its credit, Bangladesh has taken several precautionary measures. The government has strengthened heatwave warning systems through the Bangladesh Meteorological Department, expanded climate-resilient agriculture by promoting drought-tolerant crop varieties, improved irrigation management, and encouraged water conservation in drought-prone regions. In addition, local authorities have also introduced public awareness campaigns on heat-related health risks, while disaster preparedness programmes continue to integrate climate adaptation into national planning. Investments in embankments, cyclone shelters, and early warning systems have further strengthened resilience against multiple climate hazards.
We believe, yet much more remains to be done. Urban areas urgently need heat action plans, expanded green spaces, and better access to safe drinking water during prolonged heatwaves. Farmers require timely weather information, affordable crop insurance, and wider access to climate-smart technologies. And it is high time for the government to give top priority to long-term investments in renewable energy, sustainable water management and climate resilient infrastructures
To finish with, El Niño is not merely a seasonal weather event, rather it is a stark reminder that climate change is intensifying natural variability into recurring crises. Although Bangladesh has shown remarkable resilience in the face of climate adversity, but resilience alone is no longer enough.
Preparing today�"through science-based policies, stronger institutions and collective actions�"are the only way to protect lives, livelihoods, and the nation's future from a fast-warming world.
