Unprecedented Heat Waves and Rains in Sindh are worrying

Atmospheric abnormalities especially in the Sindh province of Pakistan are a cause of great concern.

What’s happening in Jacobabad is a part of a greater chain of events that have been bewildering the climate community for years. It is safe to say that the Sindh province is at the forefront of the climate crisis.

Taking the example of Jacobabad, it first recorded 50+°C in 1919 and since then all its 50°C have occurred post-2000. It is not even the hottest city in Pakistan as other towns/cities like Larkana or Moen-Jo-Daro and towns in Balochistan province have reported much higher temperatures in past years.

2011’s floods transformed a desert into an ocean!

When it comes to precipitation, with only 11.2 mm monthly average in September, Jacobabad recorded 481 mm in only 5 days in 2012 (highest ever). Another strange fact is what happened in 2011, rain in excess of 1000+ mm fell in south-eastern Sindh in only 2 months. The annual rainfall is just 50 to 150 mm.

Let’s not forget about the provincial capital of Karachi. August of 2020 recorded more rain (500+ mm) than in any previous year. While the heatwave of 2015 caused temperatures to reach above 40+°C for one whole week, which has never been observed in the past.

We are destroying the ecosystem of our country

Pakistan must realize that companies like Nestle are sucking the groundwater of the country. This is impacting the ecosystem and leading to intense heat waves along with water scarcity. The country is facing water scarcity despite a wetter winter and normal monsoon of 2021. Every catastrophic event cannot be attributed to climate change, foreign water companies are draining the moist land dry & this impacts evapotranspiration & increases the likelihood of severe heatwave.

When water companies like Nestle, Pepsi, and Coca-Cola drain groundwater, it impacts evapotranspiration which in turn increases the likelihood of a severe heat wave as the soil is not able to release moisture when the temperature rises.
