Moyhu hiatus

I'll need to be away from my computer for a few months, so I won't be blogging much. In particular, the latest data page will probably be irregularly updated, if at all. Sorry about that, it will resume.

GISS June global temperature up by 0.06°C from May.

The GISS V4 land/ocean temperature anomaly was 0.85°C in June 2021, up from 0.79°C in May. This small rise is similar to the 0.01°C increase (now 0.03°C) reported for TempLS. Jim Hansen's report is here.

As usual here, I will compare the GISS and earlier TempLS plots below the jump.

June global surface TempLS up 0.01°C from May.

The TempLS mesh anomaly (1961-90 base) was 0.671°C in June, up from 0.661°C in May. It was the fifth warmest June in the record. The NCEP/NCAR reanalysis base index fell by a lot - 0.21°C, making June about as cold as February. This was not reflected in the TempLS result.

The most prominent feature is the warmth right through Europe to the Urals, extending through the Middle East and Africa. Also warm in China and the N America, except for SE USA and the Hudson Bay area. The main cold spot was Antarctica; also India and W Siberia.

Here is the temperature map, using the LOESS-based map of anomalies.

GISS May global temperature up by 0.04°C from April.

The GISS V4 land/ocean temperature anomaly was 0.80°C in May 2021, up from 0.76°C in April. This small rise is similar to the 0.012°C increase reported for TempLS. Jim Hansen's report is here.

As usual here, I will compare the GISS and earlier TempLS plots below the jump.

May global surface TempLS up 0.012°C from April.

The TempLS mesh anomaly (1961-90 base) was 0.67°C in May, up from 0.658°C in April. It was cool relative to recent Mays, although 2018 and 2015 were a little cooler.. The NCEP/NCAR reanalysis base index rose more - 0.089°C. However, it did not rise much in April, when TempLS did.

Cold patches in W Europe and Eastern US have been talked about. Also cold in India and N Canada. But it was warm in central Russia and much of the Arctic. Also in N Africa and the Middle East.

GISS April global temperature down by 0.14°C from March.

The GISS V4 land/ocean temperature anomaly was 0.74°C in April 2021, down from 0.88°C in March. This is similar to the 0.165°C decrease (now 0.134) reported for TempLS. Jim Hansen's report is here.

April global surface TempLS down 0.165°C from March.

The TempLS mesh anomaly (1961-90 base) was 0.608°C in April, down from 0.773°C in March. That takes away much of the rise in March, and goes back to about the level in Dec/Jan, though warmer than February. It was the coolest April since 2013. The NCEP/NCAR reanalysis base index did not rise as much in March, and so did not fall in April, rising just 0.016°C. Again, April was about the level of Dec/Jan.

Many Moyhu readers will have experienced the cold patches, which were in Eastern US (also Alaska and NW Canada), Europe and most of Australia. There was also a cold band through Afghanistan/China. N Africa, S America, NE Canada and NW Siberia (and much of Arctic) were warm; Antarctica was cold.
