The average global temperature drop between October and November, 2017, tied for the fifth largest one-month-to-the-next drop in the 39-year satellite temperature record, according to Dr. John Christy, director of the Earth System Science Center (ESSC) at The University of Alabama in Huntsville. Compared to seasonal norms, the average temperature around the globe fell 0.27 C (almost 0.49 degrees F) between October and November. (The largest drop was from January to February 2013, when the global average temperature fell 0.32 C.)

After a peak in 2012 the level went down by about 10 cm by mid 2017. It is very much related to natural variations, in sync with the El Ninos (low levels) and La Ninas (high levels).
So what remains of the climate change horror stories in connection to the Fiji Islands? (…)

September Sea Surface Temperatures (SSTs) are now available, and we see downward spikes in ocean temps everywhere, led by sharp decreases in the Tropics and SH, reversing the bump upward last month. The Tropical cooling in particular factors into forecasters favoring an unusually late La Nina appearance in coming months.

This is interesting. It appears that a “pause” has developed in global sea levels. For two years, since July 2015, there has been no sustained increase in global sea level, in fact, it appears to have actually fallen a bit. This graph, provided by NASA’s Global Climate Change website, tells the story:

Satellite observations indicate that the average Arctic sea ice extent has generally decreased since the start of the satellite records in October 1978. Is this period long enough to assess whether the current sea level trend is unusual, and to what extent the decline is caused by humans?
This change in Arctic climate is often promoted as evidence that humans are causing drastic climate change. For instance, an April 29th 2017 article in the Economist (“Skating on thin ice”, pg 16) implied that the Arctic is melting unusually, dramatically and worryingly (…)

Le site carbonbrief a publié le 30 juin 2017 un article sous le titre : « Des corrections majeures aux données satellitaires augmentent de 140% le réchauffement depuis 1998 »
Précisons d’abord que Les satellites ne mesurent pas directement la température. Ils sont équipés de capteurs sensibles à la luminance de l’atmosphère et de la mer dans le spectre des infrarouges. Pour en dériver la température, des traitements informatiques sur les données brutes sont nécessaires.

It’s pretty clear that the models are producing too much atmospheric warming compared to satellites, radiosondes (weather balloons), and multi-observational atmospheric reanalyses.

For years, RSS have been an embarrassment to the climate establishment. Their satellite data has consistently shown the pause in global temperatures since 1998, which so many scientists have attempted to explain.
At the same time, the surface datasets of GISS, NOAA and HADCRUT have diverged, with the help of adjustments, to show much greater warming.
The pressure on RSS to conform has been immense, and now the inevitable has happened. Highly conveniently they have found huge errors in their previous version, and have now adjusted to a new version, v4, which miraculously finds that global warming has continued unabated after all!
