the determinants of climate change are the alteration in the conditions from normal. we can sence a rise in temparature, a more infrequent rains and monsoons, temperature variations in winter as well as summers. apart from climatic variations, the other indicators are variations in the vegetation, shifting of productive zones towards north hemisphere. receeding glaciers also tells the same story. so, the indicators can be found within our own periphery, sometimes affecting us moderately and othertime severely.

I recommend that you read the Intergovernmental Panel on Climate Change(IPCC) reports published at the UN. Although they are not perfect, they present major factors such as green house gases and earth's surface changes which can impact the earth's climate. One of my previous researches also deals with some of your questions. FYI, Article Land Cover Change Effects on the Climate of the La Plata Basin

HiOsmani,

The determinants are listed in Table 2

CO2 & other GHGs and temperature are the most considered determinants of Climate Change.

Thank you Firoz Ahmad

Dear Dr Osmani

Great issue to be discussed. We have to first define climate change (a statistically significantly differentiated climatic parameter (say temperature) between two time periods generally 30 years or more). If identified, the other climatic parameters may be considered as rainfall, humidity and number of hot days, cold days, extreme events. Even I say you can combine these all by suitable means and define a new parameter.

Regards

Dear Rajiv Pandey, Thank you very much.

You have said that you can combine climatic parameters all by suitable means and define a new parameter. Is there any index or formula to define new parameter?

For climate change the determinate can be both qualitative as well as quantitative. as said climatic parameters you can have in numeric form , GHG emissions, carbon etc quantitative. But biological parameters can be both biodiversity, species loss, migration, productivity etc. Similarly socioeconomic can be both numeric/ non numeric . Further a said by @Dr. Pandey new parameters or derived parameters, indexes can be worked out.The thing is that parameters to be arranged and weightage to be given on the basis impact on climate change.

Thank you Dr. Manmohan J.R. Dobriyal if I understand your comment, then it can be said that firstly, quantify the impact of each factor on climate change, secondly, give weight to each accordingly and then construct an index...........
