Global warming is the center of attention for every country. Global warming is a phenomenon in which the temperature of the earth rises with time. The rise in temperature occurs due to greenhouse gasses that are emitted on regular bases, the burning of fossil fuels, smoke discharge from the factories etc.
The effects of global warming are on that layer of the earth that is protecting us from various radiations and temperature rise. What happens when the earth temperature rises?
When the temperature of the earth rises it brings floods and different climatically changes. It is the key player in melting the polar icecaps and the glaciers. From the melting of glaciers, the sea level rises which bring floods and other catastrophic events.
According to NASA, carbon dioxide is highest in the air in 650,000 years, 1.8oF has risen since 1880, 13.2 % decrease in Arctic ice has occurred, Ice sheets are decreasing by 413.0 gigatons per year and the sea level is rising by 3.2 millimeters per year. These statistics give a clear picture of how global warming is affecting the world and is at its peak.
Pakistan has faced many catastrophic floods and cyclones incidents in recent years. A lot of damage has occurred to the infrastructure as well. The flood that occurred in 2010 killed nearly 1600 people and caused a damage of almost $6 billion and the heat wave in Karachi in 2015 gave death to 1200 people.
The NCCP (National Climate Change Policy) of 2012 is a guideline for documenting the policies for Pakistan. They have identified some major climate threats that will occur due to climate change; the Irregular pattern of rain, melting of glaciers of Hindukush-Karakoram-Himalaya (HKH), fouling of dams due to floods, reduction in agriculture activity, decrease in forest shed and an increase in health risk. These problems will be faced if the climate changes continue to increase.
To decrease the effect of climate change it is important to make changes in policies and to adopt greener production methods and increase the ratio of plants in the country to reduce carbon emission.
To counter climate threats, NCCP developed some other policies; to sustain economic growth by addressing the climate changes, to ensure productivity of food which is affected by climate changes, to mitigate flood problems that are rising due to climate changes –report by ADB (Asian Development Bank)
Pakistan is a country which is already facing many economic problems. Floods and droughts have been the fate of the country for long. Now, it is the time to change the fate.
