Nexus between environmental degradation and climate change during the times of global conflict: Evidence from CS-ARDL model

Abstract

There has been a substantial amount of research done on air pollution, both in terms of its history and its state at the present time. On the other hand, the ever–changing influence of climatic variables such as sun hour, air pressure, and wind speed has gotten just a small portion of the attention. This divide becomes even more apparent when one considers the ongoing conflicts that are taking place between Russia and Ukraine as well as the current state of the environment's response to climate change. In order to bridge this research gap, the goal of this study is to explore the ways in which climatological factors impact air quality, especially levels of PM2.5 and ozone, in a range of cities situated in India, during 2020–2021. Studies conducted over brief and extended periods of time have made it abundantly evident that sun hour, wind speed, and humidity have an impact on ozone levels. The study also sheds light on prospective policies that may be implemented in the future, such as those relating to carbon emission and particulate pollution such as PM2.5, in order to successfully battle the negative impacts that these variables have on the environment.
