Pakistan Faces Relentless Climate Extremes: From Heatwaves to Floods

From July 1 to August 1, 2024, Pakistan was hit by monsoon flash floods, leading to the destruction of 550 homes, 108 fatalities, and 216 injuries. The floods also severely damaged roads, bridges, and other infrastructure, causing major disruptions on national highways. More recently, on August 4, a cloudburst unleashed severe rains across several low-lying areas in Sindh and Balochistan provinces, resulting in 22 deaths, 32 injuries, damage to 263 homes, and the destruction of 312 acres of crops. This disaster has exacerbated issues of mass displacement, food insecurity, unemployment, and the risk of waterborne diseases, drowning, and malnutrition across the nation. Earlier, in June 2024, Pakistan faced an extreme heatwave with temperatures soaring above 50°C, resulting in over 500 deaths within just six days.

Researchers have found that extreme weather events are increasingly caused by unusual weather patterns interacting with each other. La Niña, a climate phenomenon in the Pacific Ocean, strengthens easterly winds over Northern India and alters tropical rainfall patterns extending from Indonesia to the west coast of South America. Additionally, Arctic warming amplifies La Niña’s effects, highlighting the connection between Arctic changes and mid-latitude weather. Over the years, stronger southerly winds from the Arabian Sea have also played a crucial role. A unique interaction between northerly winds from Europe and the southerly monsoon winds from the Arabian Sea further influences precipitation patterns. This convergence of factors results in unprecedented downpours, demonstrating the complex interplay of global weather systems influenced by climate change.

According to the Global Climate Risk Index 2021, Pakistan ranks as the fifth most vulnerable country to climate change. The ongoing trends of annual flooding and heatwaves suggest that, without significant climate mitigation efforts, the nation will face increasingly severe extreme weather events in the future. Vulnerable countries like Pakistan are on the brink of widespread devastation from climate change-induced extreme weather, underscoring the urgent need for financial and institutional support from high-income countries and a rapid phase-out of fossil fuels.
