NSW Environment Minister Robyn Parker has not met the state's climate change council - a group set up to advise the government - for more than a year, despite repeated pleas during the recent heatwaves and floods.

Departmental staff said the delay was a symptom of ''paralysis'' afflicting the government over its climate change policies, with key studies delayed or shelved. The council - comprising top business, emergency services and science leaders - has written to Ms Parker, seeking her response to its ''request for engagement''.

After Fairfax Media contacted the government this week, the minister indicated she would start consulting the council again.

In its letter to Ms Parker the council said ''current and future NSW governments may find that extreme events exceed their capacity to respond effectively with serious economic, societal and political consequences''.
