ISLAMABAD (APP): Pakistan Meteorological Department (PMD), in a recent monsoon rainfall distribution analysis, assessed that climate change has rendered a 100-km spatial shift towards west in the overall monsoon pattern in the country.
Rainfall distribution patterns have not only shifted spatially but also seasonally. The analysis shows that summer monsoon rainfalls have shifted towards late season; similarly winter rain and snowfall have also shifted towards late February and March.
Changing patterns results as emergence of new vulnerable areas to floods which include Khyber Pakhunkhwa, South Eastern Punjab and Central Sindh, an official of Ministry of Climate Change told APP on Friday.
It further revealed that most of the northern areas (upper KP and GB) remain in the same old pattern except in the post monsoon period.
While the central and southern half suffers throughout the year in terms of high rainfall variability, he informed.
It is also observed that more snowfall is received in the month of February as compared to January over recent years.
He further stated that the Ministry of Climate Change in association with Un Habitat, Capital Development Authority and Islamabad Capital Territory Administration undertook a study entitled "Climate Change Vulnerability Assessment of Islamabad".
The study reveals that the city of Islamabad and its surrounding capital territory areas exposed to a host of factors accelerating climate change impacts such as erratic behavior and marked changes in the intensity, frequency and variability of temperature, precipitation, floods, droughts, cyclones etc.
Extreme weather events recorded so far in Islamabad include highest maximum temperature of 46.6oC on June 24, 2005 and lowest at - 4.3 C on December 25, 1984. In 2001 heaviest rainfall of 621mm was recorded in 10 hours.
The main findings of the assessment reveal starling facts regarding erratic behavior and marked changes in the intensity, frequency and variability of temperature, precipitation, floods, droughts, cyclones etc.
The study proposes well though out planning interventions to make Islamabad a climate resilient city, the official informed APP.
The study also makes recommendations of utilizing the present institutional arrangements for a well coordinated effective implementation of suggested plans in Islamabad.
The ministry official further informed that a Second National Communication (SNC) Preparation of Pakistan's Second National Communication (SNC) on Greenhouse Gases (GHG) emissions has also been initiated.
"This will be a three-year study leading to stocktaking of all GHG emissions in Pakistan with options of mitigation and adaptation actions", he informed.
