The concerns were raised during a session titled 'Obstacles to Karachi's Natural Waterways and Potential Threats' held at the Karachi Press Club. Urban planner Muhammad Toheed said climate change was now an undeniable reality and stressed that while other countries had upgraded their drainage and infrastructure, Karachi remained far behind. 'Despite Pakistan being among the most vulnerable countries to climate change, the issue is still not treated with the urgency it deserves.' He also condemned the Karachi Water and Sewerage Corporation for discharging sewage into stormwater drains. Climate activist Yasir Darya warned that climate change had made weather patterns increasingly unpredictable.
