Could you build this?
Partial The interactive HTML5 canvas visualization is straightforward, but downloading, parsing, aligning, and compressing 41 years of global NetCDF/HDF satellite climate datasets requires specialized data engineering.
What it would actually take: The pipeline requires pulling multi-terabyte sea surface temperature datasets from NOAA/Copernicus, regridding and normalizing anomalies using Python (Xarray, rasterio, NumPy), and packing the spatio-temporal data into quantized tile textures or binary blobs. The frontend uses WebGL/Canvas to decode and stream these time-series textures with custom color maps and interactive playback.

Concerns raised: Scientific claims presented as indisputable fact without acknowledging uncertainty, Sulfur aerosol reduction unintentionally worsened climate by removing cooling effect, Ocean acidification problem exists independent of temperature concerns, Difficulty in deciding between air pollution vs. climate change tradeoffs, Interpretation of data (isotopes, tree rings) requires assumptions about methodology
