The climatic conditions of Pakistan:
According to the books of Pakistan studies, the significant location of Pakistan experiences four major climatic conditions of Pakistan, shaped by its diverse geography, seasonal wind systems, and varying temperature patterns.
- Cold Climate (Northern Highlands): The northern mountainous regions, including Gilgit-Baltistan, Chitral, Swat, and Kaghan, experience prolonged winters with heavy snowfall and short, mild summers. Altitude is the dominant factor here, with temperatures dropping below –10°C in winter and rising to 20–25°C in summer. This region feeds the Indus River system through melting glaciers.
- Hot Desert Climate (South west and Thar region): Areas such as Thar, Cholistan, and parts of Balochistan fall under the hot desert climate. Summers are extremely hot and dry, reaching 45–50°C, with minimal rainfall. Vegetation is sparse, and water scarcity is a persistent concern, affecting agriculture, livestock, and livelihoods.
- Topical/ Subtropical climate (Plain of Punjab and Sindh): Central and southern plains experience long, hot summers and short winters. Monsoon winds bring rainfall between July–September, which is crucial for agriculture. Temperatures can exceed 40°C in summer, while winters remain relatively mild, ranging from 5 to –15°C.
- Arid Mountain climate (western and northwestern Balochistan): These regions are dry, windy, and cold due to high altitude and significant distance from moisture sources. Rainfall is scarce throughout the year, and temperature swings between day and night are steep.
What Do We Mean by Change of Climatic Conditions of Pakistan?
The climate of Pakistan hasn’t been the same for a long time. Over the past years, every climatic zone has experienced harsh weather conditions affecting lifestyle, livestock, and livelihood negatively.
Climate change refers to long-term alterations in temperature, precipitation patterns, and weather extremes across regions. Unlike weather, which changes daily, climate trends unfold over decades. Due to increased greenhouse gases like carbon dioxide, methane, and nitrous oxide, the global climate system is warming, intensifying extreme events such as droughts, floods, heatwaves, and storms
Historical Climate Trends in Pakistan:
According to a study, Pakistan is ranked among the top 10 countries affected by climate change and natural disasters.
The climate trend changed over time with bringing significant effects in:
