|Not close to perfect
Note that I'm not even perfect on-average. (I was told that once, right before she slammed the door.)
And then my guess for GISS's May anomaly is +0.54°C, which would be the 7th-warmest May in their 133-yr record of Mays.
It definitely seems like things are heating up now that the La Nina is over. Or maybe that's just confirmation bias.
