Pakistan on the Brink: Climate Change Threatens the Nation's Economy, Health, and Existence

Strategic Insights -

Pakistan's vulnerability to climate change is undeniable, with the country bearing the brunt of rising global temperatures despite contributing less than 1% to greenhouse gas emissions. The cumulative cost of environmental degradation, melting glaciers, and erratic weather patterns has been estimated at nearly $100 billion over the past two decades, equivalent to its total external debt of approximately $130 billion. The consequences of inaction are dire, with climate-related disasters and shifts poised to exacerbate poverty, displacement, and health crises.

Key Takeaways:

  • Over the past two decades, Pakistan has suffered economic losses estimated at nearly $100 billion due to climate-related disasters and shifts, accounting for approximately 70% of its external debt.
  • The country has experienced catastrophic floods in 2010, 2012, 2014, 2020, and 2022, displacing millions and claiming thousands of lives, with damages pegged at around $30 billion in 2022 alone.
  • The soaring temperature levels in provinces like Sindh and southern Punjab have overwhelmed the national power grid, leading to frequent electricity shortages and heat-related illnesses, particularly among vulnerable populations.
  • Climate change has devastating effects on Pakistan's agriculture, with erratic rainfall patterns, droughts, and increased temperatures threatening crop yields and food security, potentially driving inflation and increased reliance on imports.
  • Glaciers in the Himalayan region are melting at an accelerated pace, threatening the availability of freshwater, and raising the risk of glacial lake outburst floods (GLOFs) and landslides.
  • Climate change impacts approximately 8% of Pakistan's Gross Domestic Product (GDP) currently, but could balloon to 30% by 2050 without decisive action.
  • Water storage and management infrastructure are inadequate, resulting in the loss of 35-40 million acre-feet of annually, with the potential for harnessing 10 million acre-feet to generate 15,000 to 20,000 megawatts of clean, renewable electricity.
  • Pakistan's climate crisis is an existential threat to national security, economic stability, and social cohesion, with a rapidly closing window to act.
