Since 1979, NOAA satellites have been carrying instruments which measure the natural microwave thermal emissions from oxygen in the atmosphere. The intensity of the signals these microwave radiometers measure at different microwave frequencies is directly proportional to the temperature of different, deep layers of the atmosphere. Every month, John Christy and I update global temperature datasets that represent the piecing together of the temperature data from a total of fifteen instruments flying on different satellites over the years. A discussion of the latest version (6.0) of the dataset is located here.
The graph above represents the latest update; updates are usually made within the first week of every month. Contrary to some reports, the satellite measurements are not calibrated in any way with the global surface-based thermometer records of temperature. They instead use their own on-board precision redundant platinum resistance thermometers (PRTs) calibrated to a laboratory reference standard before launch.
THE September anomaly represents a 0.72°C drop since 2016 super El Niño heights, bringing temps down now to ~1988 levels.
DON’T expect the mainstream media to report in this anytime soon. They are only concerned about hot and climbing temperatures to push their global warming climate change agenda.

NASA’s MSU satellite measurement systems, generate the RSS and UAH datasets, which measure the average temperature of every cubic inch of the lower atmosphere, the exact place where global warming theory is meant to occur.
HOWEVER, by 2016, Carl Mears, who is the chief scientist for RSS (Remote Sensing Systems) and who has used the pejorative “denialist” in various correspondence, decided that “the pause” was not a good look for the global warming narrative so RSS was massively adjusted upwards, conveniently eliminating “the pause” in the RSS dataset.
MEARS’ objectivity towards the business of global temperature data collection and reporting can be found in his commentary on his website:
UAH is the satellite data set featured in this post and is jointly run byDr. John R. Christy – Distinguished Professor of Atmospheric Science and Director of the Earth System Science Center at The University of Alabama in Huntsville. And Roy Spencer Ph.D.Principal Research Scientist at the University of Alabama in Huntsville.
SPENCER commentary on the divergence between RSS and UAH post “adjustment”:
“We have a paper in peer review with extensive satellite dataset comparisons to many balloon datasets and reanalyses. These show that RSS diverges from these and from UAH, showing more warming than the other datasets between 1990 and 2002 – a key period with two older MSU sensors both of which showed signs of spurious warming not yet addressed by RSS. I suspect the next chapter in this saga is that the remaining radiosonde datasets that still do not show substantial warming will be the next to be “adjusted” upward.
The bottom line is that we still trust our methodology. But no satellite dataset is perfect, there are uncertainties in all of the adjustments, as well as legitimate differences of opinion regarding how they should be handled.
Also, as mentioned at the outset, both RSS and UAH lower tropospheric trends are considerably below the average trends from the climate models.
“78 per cent of observed planetary greening is caused by carbon dioxide and its effect upon climate….”
DON’T expect the CO2-centric mainstream media to report on this latest study of dramatic “greening” of the planet thanks to CO2 fertilisation. When you’re in the business of demonising carbon dioxide for political ends, such good news comes as a rather unwelcome message.

LITTLE gem of a read by Harry Wilkinson on the condition of the Polar Ice Caps and the overtly propagandised meltdown hysteria promulgated by alarmist ‘scientists’ and their government institutions, gleefully pimped out by the ever-compliant global warming theory-obsessed mainstream media.
WILKINSON lays out basic empirical facts that shamelessly contradict the repetitive “Death Spiral” moans from climate and Arctic experts alarmists.
THE piece is a welcome reminder to be cautious of the selective bias that the mainstream media is willing to share with you on all things global warming climate change:
“These facts get little coverage because they don’t sound alarming at all, and for most reporters that means they’re not news. These ‘inconvenient truths’ are nonetheless a helpful reminder that climate change coverage should be taken with a healthy dose of scepticism.”
The latest observations show that Arctic sea ice is on course to have a greater minimum extent than in 2015 and 2016, and is running higher than levels seen a decade ago. Back then, the BBC reported that Arctic summers may be ice-free by 2013, although this estimate was described as being ‘too conservative’.
That prediction was spectacularly wrong, and contrary to warnings of an ‘Arctic death spiral’, sea ice extent has been remarkably stable in the last decade. No one can say what exactly will happen next; if this humbling affair teaches anything it should be precisely that.
The climate has misbehaved in other ways too. The Greenland Ice Sheet has been gaining mass at a record rate for the second year running, and Antarctic sea ice extent is perfectly normal relative to the 1981-2010 average. These facts get little coverage because they don’t sound alarming at all, and for most reporters that means they’re not news. These ‘inconvenient truths’ are nonetheless a helpful reminder that climate change coverage should be taken with a healthy dose of scepticism. There is a long way to go before we can make accurate predictions about how the climate will behave, if indeed we ever can.
Climate science has to be more deeply grounded in real-world observations rather than models that are inevitably riddled with flawed human assumptions.
BLINK chart of the past 15 years shows no “Death Spiral” trend in sea-ice volume. It does, however, show a large increase in multi-year, 2.0-3.5 metre thick sea-ice in 2018, that will consolidate into Autumn and go nowhere for years:
Although it is still 3-4 days away, rapidly strengthening Hurricane Florence is increasing the threat of a major hurricane landfall somewhere within 120 miles or so of Wilmington, NC. If it reaches that area as a Cat 4 storm, the damage produced will be extensive, likely amounting to tens of billions of dollars.
By coincidence, the hurricane disaster (if it unfolds) will occur during this year’s Global Climate Action Summit (Sept. 12-14) in San Francisco, possibly the most star-studded climate alarmist extravaganza in existence, with climate experts such as Al Gore, Alec Baldwin, Andrea Mitchell, Catherine McKenna, Dave Matthews, Jane Goodall, John Kerry, and Tom Steyer.
As we all know, these are people who lead by example in their efforts to reduce their so-called carbon footprints.
Attendees of the conference are almost guaranteed to point to Florence as an example of what we can…

LOWER troposphere global temperatures continue their decline off the 2015/16 Super El Niño highs.
AUGUST temps plunged off the July bump of +0.32 deg. C, cooling back to +0.19 deg. C above the long-term average.
THE August anomaly drop brings global temps back to 2002 levels…
It’s hot in lots of places. Get over it. It’s August.
By the end of the month it will cool down. And by December it will be cold. This is Canada.
The current heat wave is not a sign of global warming. It’s a sign it’s summer.
In June, it was cooler than normal in lots of the places that are now so hot. How come the climate alarmists weren’t running around then flailing their arms in the air and shrieking about a coming ice age?
There were breathless stories in Calgary this week warning the city was in for its hottest four days in 35 years – more proof that Earth stands poised on the brink of a climate catastrophe.
Yet, if this time the cause is climate change, what caused the heatwave 35 years ago?
Couldn’t have been SUVs, pipelines or the oilsands.
AS the annual Arctic melt season comes to a close, hopes of an “Ice-free” Arctic for “Death Spiral” enthusiasts are once again denied as sea-ice remains stubbornly stable for the twelfth year in a row.
Early in life I had noticed that no event is ever correctly reported in a newspaper.
Summer is over, and Greenland’s surface has gained 510 billion tons of ice over the past year – about 40% above normal. The surface mass budget is snow/ice accumulation minus melt. It does not include ice loss caused by glaciers flowing to the sea, which is very difficult to measure, and is driven by processes which have little to do with the current climate.
Heavy snow fell above 1500 metres across the European Alps this weekend with a number of destinations reporting over 40cm of the fluffy white stuff.
While it is still summer in Europe, temperatures dropped over 15 degrees and dipped into the negatives in less than 24hrs. Germany’s highest peak, The Zugspitze – at 2962m above sea level – recorded 25cm of snow whilst thermometers hit negative 7 degrees.
Although skiing remains possible across half a dozen glacier dependant ski fields throughout Austria, Italy and Switzerland, the snowfall came just days after these areas were recording temperatures in the 10’s and 20’s, with parts of Germany expecting temperatures to reach 30 degrees by mid-week.
The result of the cold front that swept across many of these resorts and throughout Central Europe is perhaps best summed up in the below images… Feast your eyes and enjoy!
