UAH's lower troposphere for April: 4th warmest April, 46 warmest month (of a total of 497). The linear trend now rounds to 0.14°C/decade.
Ocean heat content for the first three months of 2020 set a record for both the 0-700 m region and the 0-2000 m region. Last year the 0-100 m region also set a record (it's only calculated once per year), finally surpassing the El Nino year of 2016).
The Hadley Central England Temperature, a measurement of about 1 cm3 of air, saw its 5th warmest April in 361 years of record-keeping. Caveat: Many of the early decades of this record aren't considered robust.
"Robust" is science slang -- it basically means good, in all the ways that a model/experiment and its data can be good: accurate, precise, reproducible, smells good, trims its nails, etc. We should trust it and like it (until a better model/experiment and data comes along).
Finally, the South Pole -- also presumably measuring about a cc of air -- had its 6th warmest April, with records there starting in 1957. The data aren't very linear, so I'm gonna be good for once and resist providing a linear trend.
