Hi Emiley and everyone,

I have few  questions please : why don't we have ENSO records dating to years before 73 years . any explanation/reason .

Can we rely on reconstructed thermal records / or have anyone used reconstructed thermal records and other parameters to predict past ENSO states for at least the last 600 years . i appreciate your help. 

Finally, the current tripple dipped laninas have followed nearly similar pattern to that occurred during 1974-1975 with great similarity ( not identical but similar in general ). I realize it is not sufficient data to extrapolate information based on one or two seasons , but have you kindly checked the pattern ( evolution of summer  and autumn 1975 and winter then the advent into winter 1976) on global scale ,  the patterns of thermal anomalies show striking similarity . have you kindly tried to re-analyze the years 1975-1976 more indepth and contrast with 2022-2021 . I realize also  other climatic factors are into play and surprises might happen . 

Warmest regards

Mohamad Alkhateeb
