Data Analyses Show Rapid Global Surface Cooling, Growing Arctic Ice Thickness

Analyses show that global temperatures continue their rapid cooling trend, as Schneefan here writes. What follows are excerpts of his recent comprehensive analysis.

The cooling comes naturally in the wake of the moderate La Nina conditions that have ruled over the past months.

In April surface temperatures 2 meters above the ground plummeted as the following NCEP chart shows:

Foremost the atmosphere above the oceans cooled the most during March, 2017. This is clearly depicted by the UAH: an anomaly of +0.29°K to +0.09°K compared to the WMO 1981-2010 mean.

Global RSS satellite data show a rapid cooling since early 2016:

Moreover despite the powerful warming El Niño event of 2015/16, the unfalsified satellite data in 2016 show that no new significant global heat record was seen when compared to the El Niño year of 1998. We are talking about hundredths of a degree, completely within the boundaries of uncertainty.

No significant warming in 20 years

The powerful linear global cooling continued in April 2017 and will continue for the time being, Schneefan writes.

What does that mean for the global warming? Schneefan adds:

The IPCC global warming claimed by the climate models has been missing for almost 20 years. And that despite the constantly rising atmospheric CO2 concentrations!”

And just days ago, Kenneth Richards here showed that there hasn’t been any warming over the entire southern hemisphere at all. The warming of the past decades is not even global.

What is now becoming glaringly obvious is that the IPCC has wildly overestimated its projected global warming for the future. When the IPCC models from the various IPCC reports are compared to the observations, the result gets vividly illustrated by the following chart showing the satellite observed temperatures from January 2001 to June 2016:

The Speedometer for the 15 years 4 months January 2001 to April 2016 shows the [1.1, 4.2] C°/century-equivalent range of global warming rates (red/orange) that IPCC’s 1990, 1995 and 2001 reports predicted should be happening by now, against real-world warming (green) equivalent to <0.5 C°/century over the period, taken as the least-squares linear-regression trend on the mean of the RSS and UAH satellite global lower-troposphere temperature datasets.

The Global Warming Speedometer for January 2001 to June 2016 shows observed warming on the HadCRUT4 and NCEI surface temperature datasets as below IPCC’s least prediction in 1990 and somewhat on the low side of its 1995 and 2001 predictions, while the satellite datasets show less warming than all IPCC predictions from 1990 to 2001. Later IPCC predictions are too recent to be reliably testable. Source : Is the Reuters “news” agency committing fraud?

Massive Arctic ice thickness growth

The growth in so-called multiyear Arctic sea ice has been considerable over the past nine years. The Chukchi Sea and the East Siberian Sea had little thick multiyear ice back in February 2008. But by February 2017 there was a lot. Massive Growth In Thick Arctic Sea Ice:
