A coalition of former fire chiefs is blasting the federal government as being "asleep at the wheel" when it comes to global warming and its links to the bushfire crisis.

There are now 29 former chiefs in the Emergency Leaders for Climate Action, and the group is calling for a national summit to fill the "leadership vacuum" left by the Morrison government.

"What I'm seeing is an absolute crisis in the leadership that we do not have right now in this country," Former ACT Emergency Services Authority commissioner Peter Dunn told reporters in Sydney.  "Our leadership is asleep at the wheel.  In fact, in some areas, I think it's on life support."

Hashtags like #WhereTheBloodyHellAreYou, #WheresScotty, #MorrisonFires, #NotMyPM, and #HawaiiSmoko started flaring up on social media amid word that Prime Minister Scott Morrison and his family boarded a jet on Monday for a holiday in Hawaii.

"It's shameful the government has not sat down with the fire chiefs," Federal shadow treasurer Jim Chalmers said on Tuesday.  "It is shameful in the extreme that Scott Morrison hasn't taken the views of those senior firies on board."
