*Authors* Akshay Kumar Sagar & Arun Chakraborty *26 July 2025* *Abstract* A suggested strategy for avoiding the worst effects of climate change is to lower global mean temperatures through solar climate intervention via solar geoengineering. One of the most discussed ways is the stratospheric aerosol injection technique. The assessing responses and impacts of solar climate intervention on earth system along with the stratospheric aerosol injection simulations, are designed to introduce stratospheric aerosol injection using moderate emission scenarios at approximately 20 km height in 2035 and run till 2069 with a feedback or control algorithm keeping the global average temperature near or above 1.5 °C as compared with the pre-industrial value by employing different control algorithms. This study looked at various atmospheric parameters over the Indian landmass region as per the above scenario using UK Earth System Model version 1 and Community Earth System Model version 2 outputs and compared them with the previous historical years using the ERA-5 dataset. The changes of atmospheric variables over seven homogeneous regions; Peninsular India, Northwest India, West Central India, Northeast India, and Central Northeast India, Hilly Kash, and Hilly Himalaya are considered in this study. Greater changes are observed in temperature, Specific humidity, and Relative humidity over the period for all the regions for both models. The temperature at 850 hPa shows moderate to low changes in all the regions except Hilly Kash and Hilly Himalaya regions, where it shows high. The study will help adopt a strategy to overcome the climate change and global warming effect by the geoengineering approach. *Source: SpringerLink* -- You received this message because you are subscribed to the Google Groups "geoengineering" group.
