Extending the analysis to 2024\342\200\2232025 using the same four observational datasets (ERA5, GISTEMP v4, Berkeley Earth, HadCRUT5) and the same Arctic Amplification definition (OLS trend ratio, Arctic 66.5\302\260N\342\200\22390\302\260N vs global mean), we find a multi-dataset mean AA ratio of approximately 3.34 \342\200\224 compared to the paper\'s reported value of 3.8 for the 1979\342\200\2232021 window. The Arctic is still warming roughly 3.3 times faster than the global mean, confirming the direction and qualitative magnitude of the original claim. The reduced ratio reflects the inclusion of more recent years rather than any methodological divergence."

The longer window captures recent years\n   in which the global warming trend has accelerated slightly, reducing the AA ratio. A strict apples-to-apples comparison would require running the same OLS on the same 1979\342\200\2232021 window, which was not done here.\n\n2. GISTEMP Arctic boundary: GISTEMP provides pre-computed zonal means for 64\302\260N\342\200\22390\302\260N, not 66.5\302\260N\342\200\22390\302\260N as defined in the paper. This introduces a small systematic difference for the GISTEMP dataset.\n\n3. ERA5 CDS API version: the ERA5 file was downloaded via CDS API v2, which uses the coordinate name \'valid_time\' instead of \'time\'. The coordinate was renamed\n   before processing; no data values were affected.\n\n4. HadCRUT5 version: HadCRUT.5.0.2.0 was used (latest available). The paper used an earlier version; any updates to the dataset since 2022 are included here.\n\n5. No climate model comparison: the paper\'s finding that models underestimate AA (CMIP5/CMIP6 mean ~2.5\342\200\2232.7 vs observed ~3.8) was not replicated here. This\n   replication covers only the observational component.\n"
