Meteorologists are warning of a potential “super” El Niño event, possibly the strongest on record, that could impact the global climate in the upcoming months. Looking back to 1877, when sea surface temperatures in the east-central Pacific rose by an estimated 2.7 degrees Celsius, the resulting super El Niño devastated crops in India, China, Brazil, Australia, and parts of Africa, leading to a worldwide drought and famine that claimed millions of lives. Today, such a catastrophic event could affect a minimum of 250 million people, given the current global population.
In the modern era, the world faces the question of how a super El Niño could affect global conditions and if we are at risk of a similar or even more severe outcome. Unlike the late 1870s, where colonial powers disrupted indigenous food systems, today we have the advantage of early warnings.
Following the 1982-83 El Niño event, significant improvements were made in ocean monitoring, with over 4,000 instruments now continuously measuring air pressure, wind patterns, and salt levels in the Pacific Ocean. However, the downside is that the world is now experiencing higher temperatures compared to the 1980s, potentially leading to more extreme weather events associated with El Niño.
For Bangladesh, a severe El Niño could result in reduced monsoon rainfall, leading to poor Aman rice harvests and subsequent food price hikes. To mitigate the impacts, the government, NGOs, aid agencies, and local communities must take proactive measures to prepare for the effects of El Niño. This includes developing early warning systems, conducting surveys of water resources, establishing food security buffers, promoting agricultural resilience practices, and exploring international collaborations for essential resources.
As the effects of El Niño can have global repercussions, it is crucial for authorities to plan ahead and secure alternative supply chains to mitigate potential shortages. By focusing on preparation rather than panic, countries can better navigate the challenges posed by extreme weather events and ensure a more resilient response to future disasters.
