This article attempts to review the 2022 flash flood effects in the context of climate change and heat waves. Temperature increases accelerate the hydrological cycle by accumulating a large amount of water vapors in the atmosphere. According to the UN report, in 2022, around three hundred glaciers will have turned into lakes. 33 glaciers have been declared dangerous. The process of melting glaciers and mixing them with rainwater is linked to climate change impacts. Due to the combined effects of flash rain and glacier melt, the amount and flow of water have increased rapidly. In comparison to 2010, the flood of 2022 was larger in volume. The flow of the 2010 flood was 175 thousand cusecs, while the flow of the 2022 flood was 247 thousand cusecs. It is worth mentioning here that after the 2010 floods, protective nets were constructed on both sides of the Swat River from Madayan to Batkhila, due to which many villages along the river bank were saved. However, the buildings built on the banks of the Swat River in the upper hilly areas obstructed the way for water, which increased the volume of water and started flowing into the populated areas. This intensified the damage further. As per the government estimate, Pakistan faced financial losses worth 14900 million USD. Pakistan is highly vulnerable to such floods in the future and needs to work out its long-term strategy in light of the climate change policy of 2022 and the River Protection Act of 2012.
