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!

Les mesures satellitaires prétendent mesurer l’élévation du niveau de la mer avec une précision millimétrique. Or La précision des radars altimétriques s’exprime en centimètres. Comment dans ces conditions parvient-on à mesurer un taux d’élévation du niveau de la mer de 3,4 mm par an sur la période 1993-2015 ?

We conclude that model overestimation of tropospheric warming in the early twenty-first century is partly due to systematic deficiencies in some of the post-2000 external forcings used in the model simulations.

The core of Salby’s theory is derived using CO2 data from MLO’s Keeling Curve since 1958, and satellite temperature data since 1979. (His few charts reaching back to 1880 contain acknowledged large uncertainties.) His theory builds off a simple observation, that in ‘official’ estimates of Earth’s carbon cycle budget, anthropogenic CO2 is only a small source compared to large natural sources and sinks.

Critical German climate site wobleibtdieererwaermung.de (WBDE) reports that the earth’s surface is cooling, and presents the latest chart from NCEP. As of April 11, the measured global values continue to decline (black curve) as do the computed values for April 18.
The time-delayed post El Niño cooling is now showing up in the UAH and RSS satellite data.

The resulting 2016 annual average global temperature anomaly is +0.50 deg. C, which is (a statistically insignificant) 0.02 deg. C warmer than 1998 at +0.48 deg. C. We estimate that 2016 would have had to be 0.10 C warmer than 1998 to be significantly different at the 95% confidence level. Both 2016 and 1998 were strong El Nino years.

The hysteria over this issue is truly bizarre
