The New Pause has lengthened to 8 years 9 months. The least-squares linear-regression trend on the UAH monthly satellite global-temperature dataset shows no global warming from July 2015 to March 2023. As usual, this site is just about the only place where this continuing failure of global temperatures to do as they are told is reported.
The start and end dates of the New Pause are not cherry-picked. The end date is the present; the start date is the farthest back one can reach and still find a zero trend. It is what it is.
For comparison, here is the entire dataset for 44 years 4 months since December 1978. It shows a less than terrifying long-run warming rate equivalent to 1.3 degrees/century, of which 0.3 K has already occurred since January 2021, leaving just 1 K to go (on the current trend) until 2100, by which time reserves of coal, oil and gas will be largely exhausted.

The New Pause, having paused a month ago, has now lengthened again: this time to exactly eight years. As always, the Pause is calculated as the longest period for which the least-squares linear-regression trend up to the most recent month for which the UAH global mean surface temperature anomaly is available is zero.
The trend on the entire dataset during the 526 months from December 1978 to September 2022 is 0.95 C°, equivalent to only 1.34 C°/century. So slow a rate of warming is well within the natural variability of the climate, and is proving net-beneficial.
The New Pause has grown to fully eight years in length at a most embarrassing point for true-believers: for the cost to the West of the economically suicidal policies that they have long advocated is now becoming all too painfully apparent, just as it is also ever more evident that the warming since 1990 is well below half the midrange prediction made by IPCC that year.

The oceans swallowed my global warming? Desperate butt covering from alarmists who are facing increasingly embarrassing questions about the failure of the world to end.

The globe hasn’t been warming and the Arctic hasn’t been melting much for almost a decade now.
Recall the climate crisis loonies warned us some 20 years ago the Arctic sea ice would disappear by the summer of 2014. Well it’s still very much there, as Joe Bastardi reminds us at his most recent Saturday Summary:
No warming in 8 years
Moreover, UAH global mean temperature anomaly hasn’t risen in eight years as well, Hat-tip Snowfan here:

The New Pause paused last month because I was ill. Many apologies for the interruption. Now, however, it resumes – and it has lengthened from 7 years 7 months to the end of April 2022. To the end of June 2022, the New Pause is now 7 years 10 months in length:
This Pause, like its predecessor, which was an impressive 18 years 8 months (UAH), or 18 years 9 months (HadCRUT4), is, as always, not cherry-picked. It is derived from the UAH monthly global mean lower-troposphere temperature anomalies as the period from the earliest month starting with which the least-squares linear-regression trend to the most recent month for which data are available does not exceed zero. Whatever the data show, I show. Or, in the immortal words of Dr Roy Spencer, speaking of his dataset, “It is what it is”. In that splendid dictum speaks all true science.
The least-squares trend, which Professor Jones at the University of East Anglia used to recommend as the simplest and most robust method of deriving global-temperature trends, takes due account of all monthly values, not merely of the starting and ending values.

The Pause lengthens yet again, and this time by three months. The double-dip la Niña is now manifesting itself in the UAH data, so that there has been no global warming for 7 years 3 months, up from 7 years on the basis of the previous monthly data.

The New Pause has again lengthened by another two months. On the normative UAH lower-troposphere dataset there has been no global warming over the 6 years 8 months from January 2015 to August 2021. As always, the Pause is calculated as the longest period ending in the present that shows no warming trend, taken as the least-squares linear-regression trend on the UAH satellite monthly global mean surface temperature anomalies for the lower troposphere:

The New Pause has lengthened by another two months. Even though the brief la Niña that began in late 2020 has now ended, on the UAH dataset there has been no global warming for 6 years 6 months till July 2021. As always, the Pause is calculated as the longest period ending in the present that shows no warming trend, taken as the least-squares linear-regression trend on the UAH satellite monthly global mean surface temperature anomalies for the lower troposphere:

A new study demonstrates how a prolonged warming pause or even global cooling may happen in coming years despite increasing levels of atmospheric greenhouse gases — caused by natural climatic variability.
Natural climatic variability has always been a topic that contains a lot of unknowns, but it has been rarely explicitly stated just how little we know about it. Such variability has been habitually underplayed as it was “obvious” that the major driver of global temperature was the accumulation of greenhouse gasses in the atmosphere, with natural variability a weaker effect.
But the global temperature data of this century demonstrate that natural variability has dominated in the form of El Ninos. ‘Doesn’t matter’, came the reply, ‘just wait and the signal of greenhouse warming will emerge out of the noise of natural climatic variability.’ How long will we have to wait for that signal? Quite a long time, according to some researchers as more papers acknowledge that natural climatic variability has a major, if not a dominant influence on global temperature trends.
With the usual proviso concerning climatic predictions there seems to be a growing number of research papers suggesting that the global average temperature of at least the next five years will remain largely unchanged. The reason: natural climatic variability.
Only last week the UK Met Office produced figures suggesting that there is only a 1 in 34 chance that the 1.5°C threshold will be exceeded for the next five year period. Now a new paper by climate modellers extends such predictions, suggesting that because of natural variability the average global temperature up to 2049 could remain relatively unchanged – even with the largest increase in greenhouse gas emissions.
Using two types of computer models in a first of its kind study, Nicola Maher of the Max Planck Institute for Meteorology, Hamburg, Germany, and colleagues writing in Environmental Research Letters looked at the 2019-2034 period concluding that,

Christy is not looking at surface temperatures, as measured by thermometers at weather stations. Instead, he is looking at temperatures measured from calibrated thermistors carried by weather balloons and data from satellites. Why didn’t he simply look down here, where we all live? Because the records of the surface temperatures have been badly compromised.
Globally averaged thermometers show two periods of warming since 1900: a half-degree from natural causes in the first half of the 20th century, before there was an increase in industrial carbon dioxide that was enough to produce it, and another half-degree in the last quarter of the century.
The latest U.N. science compendium asserts that the latter half-degree is at least half manmade. But the thermometer records showed that the warming stopped from 2000 to 2014. Until they didn’t.
In two of the four global surface series, data were adjusted in two ways that wiped out the “pause” that had been observed.
The first adjustment changed how the temperature of the ocean surface is calculated, by replacing satellite data with drifting buoys and temperatures in ships’ water intake. The size of the ship determines how deep the intake tube is, and steel ships warm up tremendously under sunny, hot conditions. The buoy temperatures, which are measured by precise electronic thermistors, were adjusted upwards to match the questionable ship data. Given that the buoy network became more extensive during the pause, that’s guaranteed to put some artificial warming in the data.
The second big adjustment was over the Arctic Ocean, where there aren’t any weather stations. In this revision, temperatures were estimated from nearby land stations. This runs afoul of basic physics.

Using simple statistics it looked at and dismissed over 200 peer-reviewed papers that analysed the pause and concluded it was a real phenomenon. How did they, and the IPCC, get it all so wrong?

Nobody who keeps an eye on climate research will be at all surprised by this “new” paper. Its conclusions were well aired in April 2018 at a meeting of the European Geophysical Union.
The authors must have been rather frustrated at the time as the paper describing their work had been submitted to the journal Environmental Research Letters over a year earlier, in February 2017 in fact, still had not been published. This was remedied a few days ago when it was finally published — one year and nine months after its submission!
