July, 2016 Hottest Month Ever Recorded

Not merely the hottest July but the hottest month since record keeping began, even with El Niño "losing its grip."

Odd that NASA would ignore their own previously published global temperature data. Perhaps they decided to count only more recent data where they were able to compare months and tossed that older annual (estimated?) data.

Apparently Oregon missed that boat. Only one or two days topping 80 degrees. Was a very pleasant month, sweaters in the morning and late evening and perfect weather the rest of the day. We're only now getting into a week with possible 100 degree temps, about par for the course the last 45 years.

Btw, those temps are higher than the actuals. we have a real problem with heat islands (blacktop surrounding collection points) being the data collection points here in Oregon.

A warming world: July marks 'hottest month on record'


and

What makes this record particularly noteworthy is that this was the warmest month - of any month - since records began in 1880,


So what is wrong with the statement?
Well in the GISS record cited July 2016, is no where near the warmest month ever recorded, or even this year.
http://data.giss.nasa.gov/gistemp/ta...LB.Ts+dSST.txt
It was within the GISS the highest July ever by .1 C, but .48 C lower than February of this year.

You're misunderstanding what temperature anomalies are; a higher monthly anomaly doesn't necessarily mean a higher absolute temperature.

The image on the GISS page linked by the OP's HuffPo article illustrates this nicely. The NH summer is significantly hotter globally (~3 K) than the SH summer , presumably because there's more ocean in the south which reduces seasonal variation. So while January and February clearly have much higher anomalies (they're further above the average for that month), they are not higher absolute temperatures:

So . . . anomalies are the customary climate metric except when absolute temperatures have more propaganda value?

We just had our 30th day where the high was above 110, a new record. Hottest June and July here...and its already damned hot.

GLOBAL Land-Ocean Temperature Index in 0.01 degrees Celsius base period: 1951-1980

So the numbers are all anomalies from the base period.

You've hardly established yourself as any kind of authority on science. We could quibble over whether this fact is best described as science or observation, and whether "Hottest July on record; 10th record-breaking month in a row" would have been a more palatable headline for you. Either way, it's a headline only because there are still some scientifically challenged folk who think that temperatures shouldn't be rising; who even now will still insist that the globe stopped warming in 1997. I suppose outreach to these poor souls could be considered propaganda from a certain angle. Does that make you feel better about the facts?

July 2016 Was The Hottest Month Ever Recorded

This is fantastic news. But we need this sort of record warmth to extend into January. I think if we all work together we can make this the hottest year ever!! Who's with me?

I note that you continue to dodge the non-anomaly anomaly (as it were).

How many "corrections" have there been since 1880?

I'm all for a warmer earth. Though this is far from the warmest July in my area. Sometimes I wonder if it's all a smokescreen.

Except that the GISS data set is already anomaly data, and their anomaly data clearly shows that July 2016 was
not the warmest month ever, it was the warmest July in their record.

So the numbers are all anomalies from the base period.

They're monthly anomalies; that month's anomaly compared to previous months. This is covered under "Basic terminology" in GISS's FAQs:

Data.GISS: GISTEMP -- Frequently Asked Questions
Basic Terminology

Q.*What are temperature*anomalies*(and why prefer them to*absolute*temperatures)?
A.*Temperature anomalies indicate how much warmer or colder it is than*normal*for a particular place and time. For the GISS analysis,*normal*always means the average over the 30-year period 1951-1980 for that place and time of year. This base period is specific to GISS, not universal. But note that trends do not depend on the choice of the base period: If the absolute temperature at a specific location is 2 degrees higher than a year ago, so is the corresponding temperature anomaly, no matter what base period is selected, since the normal temperature used as base point is the same for both years.

Note that regional mean anomalies (in particular global anomalies) are*not*computed from the current absolute mean and the 1951-80 mean for that region, but from station temperature anomalies. Finding absolute regional means encounters significant difficulties that create large uncertainties. This is why the GISS analysis deals with anomalies rather than absolute temperatures. For a more detailed discussion of that topic, please see*"The Elusive Absolute Temperature".

Q.*Is the month with the highest anomaly the warmest month overall?
A:*No. There is a seasonal cycle in global mean temperature which means that on average, July and August are roughly 3.6ºC (6.5ºF) warmer than December and January. The*graph at right*shows how much warmer each month is than the annual global mean (derived from the MERRA2 reanalysis over 1980-2015 with an uncertainty range). An anomaly say of 1°C in December would be exceptionally warm for that month, but it is still not warmer than the average July.​

Global warming is a scam and hoax created by Barack Obama, to use tax payer money on more fake space missions. Ie. Funding nasa, the national assholery scamming association.

Seriously?

No wonder you cannot defend your views adequately. You see no shades of grey. Just binary thinking.

Perhaps it should be pointed out that the station based GISS is the one reporting a record July of any kind.

Perhaps it should be pointed out that Spencer and Christie still haven't published a paper on the methodology for their UAH version 6.x beta (it's almost 18mths now).

RSS have revised their methodology and are working on RSS VERSION 4.0
Unlike Spencer and Christie, Carl Mears and his RSS group published a paper before releasing a new version. They haven't released version 4 of TLT (lower troposphere) yet

The satellite datasets are far from stable yet.
Yale Climate Connections
Satellite or Surface Temps: Which is More Accurate?



In an email with AP, Dr Carl Mears from RSS says satellite data sets have about 5 times the margin of error compared to surface data sets.

Earth's temperature depends on where you put thermometer
"Carl Mears, senior scientist for Remote Sensing Systems, told The Associated Press in an email: "The satellite measurements do not measure the surface warming. They are measurements of the average temperature of thick layers of the atmosphere" about 50,000 feet off the ground."

"For impacts on human society and the environment, the surface data are more important," Mears said. Mears said his analysis of his own satellite data has five times the margin of error of ground measurements. That's because satellites use complex mathematical algorithms and thousands of bits of code to translate wavelength measurements into temperature readings"

 

[Quaestio]

Perhaps it should be pointed out that .....

... that you'll probably make the same old tired faulty claims about GISS anomaly datasets over and over again because you couldn't be bothered to RTFM on the GISS website even after Mithrae (and probably many others before him) showed you where you were going wrong?
