Here is the critical (click here) information and projections on climate change as outlined by ‘The Physical Science Basis’ of the IPCC’s Fifth Assessment on climate change.....
I am fairly confident 'ice fires' have to be more difficult to fight because so much of the water is taken out of the effort by the temperature.
I can't imagine the hoses being easy to handle. I would think fire hydrants might be issues as well.
Ice is considered a rock in scientific circles. Fighting rocks to put out a fire won't really work, will it?
Perhaps the fire fighting science of 'ice fires' needs evaluation to find a safety margin for the responders and an effective way to USE ice to smother the fire.
Rocks don't breath.
