Jacobabad in Pakistan, which is infamous for its unforgiving summer, recorded its maximum temperature of 49 degrees Celsius on April 30, 2022. Situated along the Tropic of Cancer, with the sun nearly overhead during the summer, the city struggles against extreme heat every year.
Climate change has made things worse for people here. Relentless carbon emissions across the world are increasing the number of hot days for the city. In fact, a 2020 study pointed out that temperatures are expected to rise further in the near future, as this region of Pakistan, like the Indus Valley, would be particularly vulnerable to climate change. He added that the city has officially exceeded the temperature threshold that human beings can withstand.
Across the border, India recorded its hottest March and April in 122 years in 2022. Northwest and central India saw average maximum temperatures reaching 35 .9 and 37.78 degrees Celsius in April. The rainfall deficit reached 72% in India. Similarly, in March, northwest India experienced an 89% rainfall deficit. The weather bureau attributed the high temperatures to low rainfall, the buildup of greenhouse gases in the atmosphere and local weather conditions, among other things.
Meanwhile, Hong Kong recorded its coldest May day in over a century on May 2. Seawater temperatures were also below normal. It comes just a year after Hong Kong announced its hottest year on record in 2021, recording a daily minimum temperature of 28 degrees Celsius on average. According to the city’s meteorologist, the “cold May” is the result of an upper-level disturbance and the northeast monsoon. However, there was no conclusive evidence to indicate that recent weather fluctuations were caused by global warming.
Similarly, in Bangkok, the temperature fell to 21 degrees Celsius, about 4 notches below normal. The northern and central regions of the country are also experiencing a cold month of May. This is rare as May was one of the hottest months in the country. According to the weather service, the low temperatures are due to an “unusually strong high pressure system from China”.
Factors such as increased concretion, deforestation and changes in land use are rapidly altering weather patterns across Asia, experts say.
