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

'continue to investigate the situation' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.

'thus temperature wavers' is the wordplay.
'wavers' indicates anagramming the letters (I've seen 'wavering' mean this).
'thus'+'temperature'='thustemperature'
'thustemperature' anagrammed gives 'PURSUE THE MATTER'.
