ascendancy

I'm a little stuck... Click here to teach me more about this clue!

'dominance' is the definition.
(I know that dominance can be written as ascendancy)

'rise up against an extremely chilly' is the wordplay.
'rise up' becomes 'ascend' (synonyms. I am not sure about the 'up' bit.).
'against' is a charade indicator (letters next to each other).
'extremely' means to remove the middle letters (only the extremes of the word are used).
'chilly' with its middle taken out is 'cy'.
'ascend'+'an'+'cy'='ASCENDANCY'

Can you help me to learn more?

(Other definitions for ascendancy that I've seen before include "Condition of being dominant" , "Domination" , "Candy canes (anag.)" , "sway" , "Dominating influence (A, not E)" .)

I've seen this clue in The Irish Times.
