Bridge Collapse Amid Heat Wave in Pakistan Raises Fears of Massive Glacier Melt Flooding

Record-high temperatures in Pakistan caused Shisper glacier to melt rapidly, triggering the collapse of the Hassanabad Bridge along the Karakoram Highway last week. With 7,253 known glaciers, Pakistan is home to more glacial ice than any other country on earth outside the polar regions. If these start melting in increasingly severe heat waves, there could be massive flooding in the country. Pakistan is among the most vulnerable to climate change.

India and Pakistan have been hit by a severe heat wave very early this summer. Jacobabad, a city in Sindh province, hit 122ºF (50ºC) in April, one of the highest April temperatures recorded in the world. Dadu, another city in Sindh, recorded 117ºF (47ºC). "This is the first time in decades that Pakistan is experiencing what many call a 'spring-less year," Pakistan's Minister of Climate Change, Sherry Rehman said in a statement. The consequences of rising temperatures in South Asia could be very severe, ranging from crop losses, food shortages and floods.

Pakistan's contribution to global carbon emissions is less than 1% but it is still ranked among countries most vulnerable to climate change. The energy-hungry nation needs help to finance climate-friendly development of clean energy sources and climate-resilient infrastructure. Last year at COP26 conference in Glasgow, Pakistan provided its NDCs 2021 (national determined contribution 2021) to the United Nations ahead. Some of Pakistan's NDC targets are voluntary while others are contingent upon the receipt of financial assistance from the rich nations most responsible for the climate crisis. Some of Pakistan's solution are nature-based such as its Billion Tree Afforestation Project (BTAP) while others require significant increase in low-carbon energy from wind, solar, hydro and nuclear.

Malik Amin Aslam, former Prime Minister Imran Khan's special assistant on climate change, said in an interview with CNN that his country is seeking to change its energy mix to favor green. He said Pakistan's 60% renewable energy target would be based on solar, wind and hydro power projects, and 40% would come from hydrocarbon and nuclear which is also low-carbon. “Nuclear power has to be part of the country’s energy mix for future as a zero energy emission source for clean and green future,” he concluded. Here are the key points Aslam made to Becky Anderson of CNN:

1. Pakistan wants to be a part of the solution even though it accounts for less than 1% of global carbon emissions. . Extreme weather events are costing Pakistan significant losses of lives and property.

2. Pakistan is among the countries most vulnerable to the effects of climate change.

3. Pakistan is moving towards renewable energy by converting 60% of its energy mix to renewable by 2030. Electric vehicle (EV) transition is also beginning in his country.

4. Aslam said: “We are one of the world leaders on nature based solutions. However, the World Bank (WB) in its Report yesterday came up with really good numbers in a comparison done of countries who are shifting their mainstream development towards environment friendly policies and Pakistan came atop among them,” the SAPM explained.

COP26: Climate Change, Modi, Methane and Cow Burps/Farts

India's largest cow herd in the world makes it the third biggest global methane emitter. Methane is a potent greenhouse gas with a global warming potential (GWP) 84 times greater than CO2. At COP26 in Glasgow, 104 nations agreed to cut methane emissions by 30% by 2030. India, represented by Prime Minister Narendra Modi, refused to join this agreement, as did the top two emitters China and Russia. Pakistan, the 8th largest methane emitter, did make the methane cut pledge.

Cattle Emissions:

Cow burps and farts are major contributors to global warming. The digestive processes of ruminants, including buffalos and cows, produce methane, a greenhouse gas which is 84 times more potent than carbon dioxide in warming the planet. India has over 300 million ruminants, about one-third of the global cattle herd population. Pakistan has about 100 million buffalos and cows.

Methane Emissions From Fossil Fuels.

Industrial Emissions:

Majority of the methane emissions in the industrialized world come from fossil fuels, including natural gas, oil and coal. In India, about 30% of the methane comes from industrial processes while 70% is contributed by livestock. In Pakistan, industrial and domestic consumption of natural gas contributes 40% of methane emission while the rest come from agriculture. There is strong correlation between industrial emissions and GDP intensity. The regions with the highest GDP per kilometer have the highest levels of industrial emissions of CO2 and methane.

Solutions:

Both industrial and agriculture sources of methane emissions need to be managed to achieve 30% cut by 2030 pledged by 105 nations. Industrial emissions will require plugging leaks in the production, transmission and distribution networks of natural gas.

There are a number of ideas being pursued to reduce emissions from buffalos and cows. These range from animal feed additives to produce less gas to the use of face masks.

A sensor in the animal face mask detects the percentage of methane that is expelled when the cow exhales. When methane levels exceed a certain limit, the mask channels the gas towards an oxidation mechanism inside, which contains a catalyst that converts methane into CO2 and water, and expels it from the device.

Summary:

Burps and farts from ruminants like buffalos and cows are a major source of global warming. These emissions contain methane gas which is 84 times more potent than CO2 in causing global warming. In addition, there are significant methane emissions from industrial and domestic use of fossil fuels like natural gas, oil and coal. At COP26 in Glasgow, 104 nations agreed to cut methane emissions by 30% by 2030. India refused to join this agreement. Pakistan, the 8th largest methane emitter, did make the methane cut pledge.
