Changing trends of thermal extremes in Pakistan
- States heat waves are thought to be more pronounced now in most parts of the world, and especially in South Asia, but doubts remain
- Aims to calculate the frequency and intensity of heat waves in South Asia, focusing on Pakistan and identifying the regions within Pakistan that are most vulnerable to heat waves
- Performs analyses both at provincial and country levels from 1961 to 2009
- Finds a positive trends for heat waves of magnitudes ≥40°C and ≥45°C for 5 and 7 consecutive days
- Finds an increase in the frequency of 5 and 7 consecutive days heat waves at all defined temperature thresholds in a countrywide analysis
- Anticipates that with a long term rise in temperatures around the globe, heat waves will become more frequent and intense in all parts of the world, including Pakistan
