Pct of Earth with Warmest and Coldest Decade

Here's an interesting result from climatologist Brian Brettschneider -- the percentage of Earth with the warmest and coldest decade since 1900:

BTW, GISS found 2019 was the 2nd warmest year for the globe in their records. Easily the warmest ENSO-neutral year. And it was the warmest year in the southern hemisphere. Northern hemisphere and land-only were the 2nd warmest year. This is the 5th year in a row that the land-only anomaly was > 1°C -- for 2019 it was 1.3°C (2.3°F). For Dec-19 it was a high 1.52°C (2.74°F) -- the 3rd warmest month ever (viz. third highest anomaly).
