KHRONOSTAT includes various statistical tests. These tests are specific behavioral change of the variable in the time series. such as rainfall, temperature...

First, you need to do an analysis of the recent changes of temperature and precipitation, and probably of extreme climatic events, to understand what have happened and why. Then you can choose an impact model to simulate the impact of the past change in climate on, say, agriculture or water resources in the concerned area. You may need to use the model to simulate future impact of the projected climate on agriculture or water resources. With those, you could design a set of adaptation measures for the area. A problem is the uncertainty of the projection of future climate generally obtained by applying climate models.

Thank you Rajiv Pandey, the papers are so helpful.

I have my own aproach, others quite diverge from it

Thank you Dimis Poulos that was quite informative

I have added some notes too on the solar cycles, sun spots etc and their 11 and 256 year periodicities and some critics on modern popular data presentations
