Climate change is a bitter part of our lives now. Weather patterns are getting wild. Stormy weathers have become more frequent. Mother Nature is unleashing fury more often now. Sea levels are rising and glaciers are melting swiftly. And consequently, lives of millions of people are at risk around the world. “We will respond to the threat of climate change “, US President Barack Obama once remarked. While it is obvious that the far sighted countries around the world are developing new strategies to take on this new challenge, Pakistan still lags behind in adaptation with climate extremes and suffers from inadequate financial and technical capacity to deal with climate change. Moreover, Pakistan is among the most vulnerable countries to climatic changes which have cost in billions so far, yet less measures are being taken as per international recommendations to minimise the havoc it is wreaking upon the country as some of the recent events in the past are testimony to this fact. However, it is a high time that Pakistan may take into account future impacts of climate change more seriously and adopt required measures to tackle this challenge.According to government estimates, adverse and increasing effects of climate change have cost Pakistan $20 billion in a detailed report submitted before the National Assembly by the government which admitted that Pakistan is among the countries which are most vulnerable to climate change. Earlier in July last year, a heavy downpour created flash floods and glacial lake bursts in Chitral valley, leaving a trail of destruction across the district. Unusual weather patterns of this sort are becoming more and more frequent, and almost always hit the mountainous areas the hardest. Today, we are hearing warnings that Pakistan is on the front lines of climate change, and it sits in the shadow of the most seismically active fault lines in the world. Similarly, 1,200 people died in Karachi last Ramadan owing to unusual heat waves. Climate warming at global level presents a more horrifying picture. According to the Climate Risk Index 2015 prepared by German watch between 1994 and 2013, more than 530,000 people have died worldwide and losses worth $2.17 trillion were inflicted as a direct result of over 15,000 extreme weather events. Likewise, as per one estimates, average monthly temperature for 2014 was 14.6 degree Celsius compared to 14.1 in 1991. These facts reflect some unusual changes in global climate which is causing some of unfathomable damages to human beings. For instance, spread of dengue disease, zika virus spread, 2004 Indian Ocean tsunami and 2008 Cyclone Nargis in Myanmar are some manifestations of the perfect storm of this climate change.Provided the grave challenge climate change presents, time and again world leaders come together to hold conferences to cope with global warming. In this regard, the most recent conference was held in Paris in 2015 called UN COP21. A total of 195 countries adopted the first-ever universal, legally binding global climate deal. The ambitious and balanced agreement, the first major multilateral deal of the 21st century, sets out a global action plan to put the world on track to avoid dangerous climate change by limiting global warming to well below 2…C compared to pre-industrial levels. As already have been said, Pakistan has received incalculable losses due to global warming. In the last two decades, climate changes have brought some unprecedented devastation upon the economically strained nation. Moreover, these impacts of climate changes are so deep and obvious particularly in the context of Pakistan that anyone can narrate her observations about the climate changes which has been caused in the last two decades. Being a Pakistani, I have made following observations which I will like to share in my article here. In the last few years, parts of Punjab and Khyber Pakhtunkhwa have seen unprecedented increase in fatalities due to dengue virus. As the average temperature rises up, atmosphere becomes more favourable for mosquitoes growth and breeding which spread this virus with higher rates. Similarly, zika virus and some other diseases were not known among common populace until the effects of climate change were began to feel around the globe.Climate change has direct connection with the security of food, water and energy. Global warming is causing the ice melt down which forces the dams to rupture resulting in floods. These floods not only devastate human villages but also cause serious destruction to agriculture. Besides, it also contributes in fuelling energy crisis because infrastructure is destroyed and government funds. Karachi has never known such severe weather conditions, but thanks to human industrial activities which has enhanced carbon emission many folds without giving any regard to keeping average temperature rise below 1.5 degree Celsius.
