Can We Determine Antarctica's Average Temperature? Yes, We Can.

The claim that it's "impossible" is false. Scientists routinely calculate Antarctica's average temperature using robust methods:

Data Sources

• Staffed Research Stations: ~70 year-round bases (McMurdo, Amundsen-Scott, Vostok, Halley, etc.) with continuous meteorological records (some 60+ years).
• Automatic Weather Stations (AWS): ~100+ remote units on ice sheet, coast, mountains. Solar-powered, satellite-telemetered.
• Satellite Remote Sensing: IR/Microwave sounders (AIRS, AMSU, MODIS) retrieve skin & air temps continent-wide since 1979.
• Reanalysis Models: ERA5, JRA-55, MERRA-2 assimilate all observations into physically consistent gridded datasets.

Results

• Continental Annual Mean: ~−57°C (−70°F) [varies by dataset/period].
• Coastal Mean: ~−10°C to −15°C.
• Interior (Plateau) Mean: ~−50°C to −60°C.
• Record Low: −89.2°C (−128.6°F) at Vostok (1983); satellite suggests −98°C in hollows.

Challenges ≠ Impossibility

Sparse coverage (vast interior), extreme conditions (sensor drift, power), and complex topography require careful statistics—but not impossibility. Uncertainty is quantified. Trends (warming peninsula, stable/cooling interior) are well-established.
