'The Antarctic ice-mass is increasing. It is at near record highs.'
That is not inconsistent with a warming planet. Warmer air and a weaker vortex allows moist air to blow over East Antarctica and fall as snow.
The Zwally study you are probably referencing (https://www.nasa.gov/feature/goddard/nasa-study-mass-gains-of-antarctic-ice-sheet-greater-than-losses) has issues highlighted by the author which are often lost in the noise. Zwally's data only covers part of Antarctica and it only goes up to 2008. Zwally found that ice was accumulating in East Antarctica as predicted, but Zwally also pointed out that loss of ice in the West and the Peninsula was accelerating and would outstrip accumulation within the next two decades.
Zwally's study also conflicts with other NASA data from the GRACE satellite which measures the mass of Antarctica. That shows a clear trend of mass loss at a rate of 125Gta. So far, Zwally is an outlier in the data which suggests Antarctica is net losing mass.
'Polar bear numbers are increasing.'
Possibly, but it's probably due to the cessation of hunting of polar bears rather than purely natural causes. Even the people who study polar bears admit there are huge uncertainties over their numbers and the health of populations:
