In some state districts, annual temperatures may increase by 0.83°C by 2040, alongside shifting rainfall patterns marked by significant changes in precipitation and dry spells.
Several districts, including Jorhat and Majuli, are projected to experience high wet bulb temperatures exceeding 31 degrees, posing health risks during heatwaves. Nagaon is expected to see a 1.95 degree Celsius increase in annual wet bulb temperature, leading to more heat-related health challenges, as per Azim Premji University’s projections released in Bangaluru by scientist Santonu Goswami.
Tinsukia, Dhemaji, and Dibrugarh are expected to have the highest mean annual temperature rise with Tinsukia at 0.83 degrees, Dhemaji at 0.76 degrees, and Dibrugarh at 0.74 degrees. These districts will also experience an increase in mean summer maximum temperature, with Tinsukia rising by 0.52 degrees and both Dhemaji and Dibrugarh by 0.44 degrees.
In winters, temperatures in South Salmara-Mankachar, Udalguri, and Chirang will rise by 1.4 to 1.6 degrees, potentially affecting agriculture, biodiversity, and energy needs, according to Goswami.
Darrang may face a 7.54 per cent rise in dry spells during the Northeast monsoon, with a potential 68.12 days without rain. Meanwhile, South Salmara could experience up to 46.88 days of heavy rainfall in the Southeast Monsoon. Hojai might see a reduction of heavy rainfall days by 11.08 percent during the Northeast Monsoon. Most Assam districts are expected to receive up to 15 per cent less rainfall during the Northeast monsoon. These changes are predicted to worsen water shortages, affecting irrigation and drinking water supply. Altered rainfall patterns could disrupt agricultural cycles, posing challenges for Assam’s economy. The study, based on IPCC’s Shared Socio-economic Pathways, suggests potential impacts of climate change and highlights the importance of moderate emissions reduction and adaptation efforts.
