In April, 2020, the Northern Hemisphere experienced its 2nd largest 2-month drop in temperature in the 497-month satellite record.

The Version 6.0 global average lower tropospheric temperature (LT) anomaly for April, 2020 was +0.38 deg. C, down from the March, 2020 value of +0.48 deg. C.

The Northern Hemisphere extratropical temperature anomaly fell from +1.04 deg. C to 0.41 deg. C from February to April, a 0.63 deg. C drop which is tied (with January 1997) for the 2nd largest 2-month drop in the 497-month satellite record. The largest 2-month drop was -0.77 deg. C from December 1987 to February 1988.

The linear warming trend since January, 1979 has now increased to +0.14 C/decade (but remains statistically unchanged at +0.12 C/decade over the global-averaged oceans, and +0.18 C/decade over global-averaged land).
