Pakistan’s annual average temperature increasing by 0.5°C


ISLAMABAD: Over the last five decades, Pakistan’s annual average temperature has increased by roughly 0.5°C, which raised the number of heat wave days per year nearly fivefold during the last three decades.

According to the Climate Change Profile of Pakistan report, published by the Asian Development Bank, precipitation has shown high variability but has slightly increased in the last 50 years.

Sea level along the Karachi coast has risen approximately 10 centimeters in the last century, devouring thousands of hectares of coastal lands, according to the report.

The report further warns that the annual temperature in Pakistan is expected to rise by 3°C to 5°C due to a central global emissions scenario, while higher global emissions may yield a rise of 4°C to 6°C.

Predicting the future scenario of the sea-level rise, the report said that the sea-level will to go up by a further 60 centimeters by the end of the century and affect the low-lying coastal areas south of Karachi toward Keti Bander and the Indus River delta.

According to the report, Pakistan is expected to experience increased variability of river flows due to increased variability of precipitation and the melting of glaciers.

The report findings highlighted that climatic changes might potentially bear various negative effects on the country’s farm productivity and water availability, increase coastal erosion and seawater incursion and frequency and intensity of extreme weather events.
