Confusing to my logical study of global warming etc (11)
I believe the answer is:
climatology
'study of global warming etc' is the definition.
(climatologists study the world's climate)
'confusing to my logical' is the wordplay.
'confusing' indicates an anagram.
'to'+'my'+'logical'='tomylogical'
'tomylogical' is an anagram of 'CLIMATOLOGY'.
(Other definitions for climatology that I've seen before include "Study of conditions" , "Study of long-term weather" .)
