I want to know in detail about global shift in climate regimes around the 1970s to 1980. Can you provide me some proofs/ source/ publications in support of such shift?
Based on the applied material, it is possible to trace the dynamics of air temperature at the high – altitude levels of the Eastern Caucasus -flat, low-mountain, mid-mountain and high- mountain.
If I understand your question right, you are looking for material about global policy cooperation in climate change phenomena. For example, you can try to look at the chapter Article The History of the Global Climate Change Regime
Dear Subharthi Sarkar , you are welcome. If these tips are useful for you, you can use keywords as "the history of the UNEP", "the history of the UNDP". I hope that you will find more information about the history of climate regimes.
Climate shift in mid 1970s and some associated reasons for it are proposed in
B. Giese, S. Urizar, N. Fuckar, Southern hemisphere origins of the 1976 climate shift, Geophys. Res. Lett. 29 (2002).

We also worked on the changes during the regimes shift. If interested you may look into the below paper as well
