Abstract

Ever since our earth came into existence, natural processes have been shaping its climate swing it towards warming and cold episodes. Post 1970, greenhouse gas (GHG) emissions were found to be responsible for the recent warming of our climate. The ways how these natural and anthropogenic drivers drive our climate through positive and negative feedbacks is the key to a stable climate. Climate change is a reality that has happened in the past and is inevitable in the future, but its prediction in the short and longer term is crucial for sustaining life and our environment. Our understanding of climate change is based on geological proxies and observed data, which are ridden with uncertainties. The past climate was never in the balance, but improving our understanding of the aspects of climate feedbacks and their interaction with the earth system processes is the key to future climate.
