Sir: Environmental experts have claimed that Pakistan is among the top ten most vulnerable countries to climate change, and where weather patterns were marking a major environmental impact. They have further stated that the situation might deteriorate in the coming years if a national policy is not designed to cope with the situation. Due to massive tree cutting and rapid urbanisation, temperatures in the federal capital and other cities have regularly started to cross 44 degrees Celsius in the summers. Furthermore, the country has experienced flooding every year since 2010 that has caused enormous devastation of life. As the impact of global warming continues to grow, perhaps the biggest security threat facing the country is the possibility of climate change and environmental factors destabilising Karachi, which is regarded Pakistan’s economic backbone. It is worth mentioning that the ministry of climate change has conducted studies on climate change, climate extreme and impact of climate change on water resources and agriculture. Climate change projection made at the Global Change Impact Studies Centre indicates that the average temperature over Pakistan will increase in coming decades at a pace faster than that of the global mean temperature. It may exceed by about 1oC by the end of this century resulting in the increase in the probability of extreme climate events such as floods and droughts. Given the above, government of Pakistan must prioritise its response to climate change in order to mitigate environmental threats and prevent further calamities. Also, the federal and provincial governments need to take active measures to reduce their vulnerability and boost their adaptability against climate risks. KHAN FARAZ Peshawar
