Climate Change Exacerbates Extreme Monsoon Rains in Pakistan

Pakistani farmers are already struggling to cope with the unpredictable and damaging rainfall during the summer monsoon. Recent extreme monsoon rains have caused widespread flooding in the country, with devastating consequences for communities and the environment. As part of a region that is experiencing intense climate change, Pakistan is particularly vulnerable to the impacts of rising temperatures and changing precipitation patterns. The effects of climate change are far-reaching, affecting ecosystems, human populations, and the physical environment.

Key Takeaways:

• The 2025 summer monsoon has brought record-breaking flooding to Pakistan, with water and mud destroying ancient towns and streets in Karachi, a vital port city.
• Pakistan has suffered from a range of climate-related disasters, including lethal heat waves and flash flooding, with a total of 27 million people affected in 2022.
• The country's glaciers are melting at an alarming rate, with the Andes mountain range, where Pakistan's glaciers are located, experiencing rapid warming.
• Glacial lake outburst floods, such as the one that occurred on Aug. 22, 2025, in Pakistan's northern Gilgit-Baltistan region, pose a significant threat to communities downstream.
• The loss of reflective snow and ice cover contributes to further warming, with temperatures increasing by 0.18 degrees Fahrenheit (0.10 Celsius) per decade in the early 20th century to rising at about 0.58 F (0.32 C) per decade by the early 21st century.
• Deforestation and the building of homes in flood plains exacerbate the risk of flooding, with Pakistan losing about 8% of its tree cover, primarily to logging.
• Pakistan ranks out of 192 countries in terms of being ready to deal with disasters, despite being one of the countries that has been most affected by climate-related disasters over the past two decades.

Statistics:

• Since 1980, Pakistan's population has grown from 112 million to over 250 million people.
• The Indus River Basin's lower reaches are particularly prone to flooding, with the country's floods often triggered by heat waves.
• Pakistan's tree cover loss stands at approximately 8% since 2003.
• The country has seen a total of 27 million people affected by climate-related disasters in 2022.
• The Pakistan National Disaster Management Authority has reported a total of 14,972 relief camps established in response to the recent flood.
