For monitoring global temperature change, thousands of thermometers would likely be a better resource than thousands of penguin chicks. Those thermometers disagree with you...and your chicks. Again, what's with the chick thing?

You are correct about Antarctic sea ice being at record levels. Sea ice extent around Antarctica has been at record or near-record lows since 2016.

Sea level (not "sea water") is trending higher at about 3.4 mm/yr. This increase, just as with temperature rise, is not monotonic. The short-term variations from that trend are caused by internal variability. The long-term trend is the result of that global warming that you oddly assert is not happening. It's that whole ice melting/thermal expansion thing.
