UAH Global Temperature Update for June, 2017: +0.21 deg. C
by Roy W. Spencer, Ph. D.
Lowest global temperature anomaly in last 2 years (since July, 2015)
The Version 6.0 global average lower tropospheric temperature (LT) anomaly for June, 2017 was +0.21 deg. C, down from the May, 2017 value of +0.44 deg. C (click for full size version):
Global area-averaged lower tropospheric temperature anomalies (departures from 30-year calendar monthly means, 1981-2010). The 13-month centered average is meant to give an indication of the lower frequency variations in the data; the choice of 13 months is somewhat arbitrary… an odd number of months allows centered plotting on months with no time lag between the two plotted time series. The inclusion of two of the same calendar months on the ends of the 13 month averaging period causes no issues with interpretation because the seasonal temperature cycle has been removed as has the distinction between calendar months.
The global, hemispheric, and tropical LT anomalies from the 30-year (1981-2010) average for the last 18 months are:

NOTE: We have added the Metop-B satellite to the processing stream, with data since mid-2013. The Metop-B satellite has its orbit actively maintained, so the AMSU data from it does not require corrections from orbit decay or diurnal drift. As a result of adding this satellite, most of the monthly anomalies since mid-2013 have changed, by typically a few hundredths of a degree C. The 1979-2017 linear trend remains at +0.12 C/decade.
The UAH LT global anomaly image for June, 2017 should be available in the next few days here.

Any decent Meteorologist could verify the June Global surface cooling. Give me 2,000-years of Satellite Data. The short POR makes the data rather meaningless except for the
fact that there is obviously no runaway warming/ cooling whatever. We simply seem to be measuring minor undulations in ENSO.
Re: Surface “data” – is there any other branch of science where past data are constantly changing like this?
History of North Korea.
Not strictly “science” but otherwise the comparison is worryingly accurate. . .

“With the current low rebound only of Pacific temps plus the pleading slowdown in PIOMAS loss I am expecting a very sharp fall in UAHv6.”
Two good reasons, rarely rewarded thus.
The anomaly for a single month can scarcely be taken as an indication of climatic cooling (or warming). As long as the yearly global average is positive and greater than ~0.25, the climate is obviously still in a warm phase.

no
it has been globally cooling for quite some time now, on average,
but you guys and indeed the powers that be
don’t even know how to take a globally representative sample
never mind how to look at that sample [of weather stations] getting the minimum amount of error
henry p:
Since you have no idea of the methodology I employ, your claims are presumptuous prattle.
True enough
no
I have no idea how you – presumably and hopefully from your own results – came to the conclusion that earth is still warming [up]
since you have not shared your results with me.
I do know from my own results that earth is cooling.
the sun will be making its mark soon.
Game over for anyone still believing AGW exists.

less polar solar field strengths =>
more of the most energetic particles released =>
Sun feels hotter =>
earth is defending =>
more ozone, peroxides and N-oxides formed TOA => (check!)
less UV coming into the oceans => (check!)
globally cooling.
