The Globe Has Not Been Warming . . . So Why It Is Called Global Warming?

As of the end of January, another 17 papers had already been published in 2017. 17 New (2017) Scientific Papers Affirm Today’s Warming Is Not Global, Unprecedented, Or Remarkable.
Within the last month, another 14 papers have been published that continue to cast doubt on the popularized conception of an especially unusual global-scale warming during modern times.
Yes, some regions of the Earth have been warming in recent decades or at some point in the last 100 years. Some regions have been cooling for decades at a time.  And many regions have shown no significant net changes or trends in either direction relative to the last few hundred to thousands of years.  In other words, there is nothing historically unprecedented or remarkable about today’s climate when viewed in the context of natural variability.

Un estudio dendroclimático, la imágen que pones es del modelo  CRU TS v.3.22 para los puntos de donde han cogido los árboles (por encima de 1500mts), más todas las observaciones que apuntan sobre la climatología, microclimas,....

interesante estudio....pero del que no se puede sacar conclusiones claras ni interpolables.

los datos del estudio están en la página 100-101 y son estas que adjunto:

The sun drives climate: Spain and Portugal

Spain:
Does the sun influence climate? In today’s post we would like to introduce new studies from Spain and Portugal that shed light on this. In February 2017 a tree-ring study appeared in Climate of the Past. It was authored by Ernesto Tejedor et al, who made a temperature reconstruction for the Iberian Peninsula for the past 400 years.
The authors emphasize that the temperature fluctuations fit very well with the fluctuations in solar activity.
Warm phases coincide with periods of high solar activity. In total the region of study warmed up almost 3°C over the past 400 years, which reflects the transition from the Little Ice Age to the modern warm period — see figure below. However there were phases around 1625 and 1800 when temperatures were at today’s levels for a short time.
Portugal:
Next comes Portugal. Anna Morozova and Tatiana Barlyaeva analyzed the temperature curve of the past 100 years in Lisbon, Coimbra and Porto. Here they found a weak but statistically well supported signal of the 11-year and 22-year solar cycles on the temperature data. In the study’s main text we read:
Weak but statistically significant (bi-)decadal signals in the temperature series that can be associated with the solar and geomagnetic activity variations were found. These signals are stronger during the spring and autumn seasons. The multiple regression models which include the sunspot numbers or the geomagnetic indices among other regressors have higher prediction quality. The wavelet coherence analysis shows that there are time lags between the temperature variations and the solar activity cycles. These lags are about 1–2 years in case of the 11-yr solar cycle as well as in case of the 22-yr solar magnetic cycle (relatively to the solar polar magnetic field observations). These lags are confirmed by the correlation analysis. The results obtained by these methods as well as comparison to results of other studies allow us to conclude that the found (bi-)decadal temperature variability modes can be associated, at least partly, with the effect of the solar forcing.”

 

Scientists Reveal How Man-Made Global Warming Is Created Via Data Manipulation, Dismissing The Sun

In late 2015, Soon, Connolly, and Connolly (hereafter SCC15) published a  comprehensive (101 pages) analysis of how the modern anthropogenic global warming (AGW) paradigm has been constructed. The paper, published in Earth Science Reviews, is entitled Re-evaluating the role of solar variability on Northern Hemisphere temperature trends since the 19th century.
What follows is a very brief summary of some of the graphical highlights in SCC15 as well as the fully cited conclusion. Succinctly, the paper can be divided into 2 parts.
1. The instrumental temperature record has undergone heavy adjustments (a utilization of an urban temperature station siting bias) to allow a better fit with climate models that presume CO2 emissions drive temperature.
2. CO2-based climate models do not adequately correlate with Northern Hemisphere (NH) temperature trends of the last 130 years; solar activity changes do correlate well with NH trends — especially when urban bias has been removed from the temperature record.
Conclussion/Summary:
… “it seems that most of the temperature trends since at least 1881 can be explained in terms of solar variability, with atmospheric greenhouse gas concentrations providing at most a minor contribution. This contradicts the claim by the latest Intergovernmental Panel on Climate Change (IPCC) reports that most of the temperature trends since the 1950s are due to changes in atmospheric greenhouse gas concentrations (Bindoff et al., 2013).”

 

Slowdown: The braked warming of the last one and a half decades and its reasons

In a recent paper published in Scientific Report, LIU Bo and ZHOU Tianjun from the Institute of Atmospheric Physics, Chinese Academy of Sciences have investigated the atmospheric anomalous features during the global warming hiatus period (1998-2013). They show evidences that the global mean tropospheric temperature also experienced a hiatus or pause.
... According to LIU, the IPO is a robust, recurring pattern of sea surface temperature anomalies at decadal time scale. During a positive phase of IPO, the west Pacific and the mid-latitude North Pacific becomes cooler and the tropical eastern ocean warms, while during a negative phase, the opposite pattern occurs. The IPO has shifted from the positive phase to negative phase since 1998/1999, and this transition has led to the weakening of both Hadley Circulation and Walker Circulation, which served as a hub linking the three processes mentioned above.
... In other words: The hiatus was triggered by ocean cycles. This by the way was already discussed in 2012 in our book “Die kalte Sonne” (The Neglected Sun). Perhaps this message will eventually reach Potsdam.

 

There Has Been No ‘Global’ Warming In The Southern Hemisphere, Equatorial Regions

To measure the historical temperature record for the bottom half of the planet, then, scientists use proxy evidence from such sources as ice cores or alkenones to reconstruct past climates.  When they do that, a common theme emerges.  The proxy evidence used in temperature reconstructions suggests that there has been no significant changes in temperature from Antarctica to the regions near or just above the equator in the last few centuries.  In other words, half the globe has not been following along with the anthropogenic “global” warming narrative.
Listed below are about 3 dozen graphical reconstructions indicating no obvious warming trend during the last few hundred years of assumed anthropogenic influence on surface temperatures.
 

3 Chemists Conclude CO2 Greenhouse Effect Is ‘Unreal’, Violates Laws Of Physics, Thermodynamics

In a newly-published scientific paper, meteorologist and physical chemist Dr. Martin Hertzberg (and two other chemists) provide a condensed update to the Gerlich and Tscheuschner appraisal of the theoretical greenhouse effect.
Hertzberg and colleagues also apply the standard laws of physics to critique 6 current theoretical explanations for the role of greenhouse gases (CO2) in presumably keeping the Earth 15°C warmer than it would otherwise be.

Conclusion
The various stated definitions of the greenhouse effect have been subjected to the rigorous scrutiny and application of the fundamental laws of physics and thermodynamics. They were found to be unreal, and unless some new definition can be put forward that satisfies and complies with those laws, it can only be concluded that the concept of a ‘greenhouse gas’ or a ‘greenhouse effect’ has not been demonstrated and is thus without merit.

17 New Scientific Papers Dispute CO2 Greenhouse Effect As Primary Explanation For Climate Change

“Nothing in the data supports the supposition that atmospheric CO2 is a driver of weather or climate, or that human emissions control atmospheric CO2.”

 

New Paper: CO2 Has ‘Negligible’ Influence On Earth’s Temperature

The purpose of this study is to present robust evidence that the sun is working with water vapour to control the Earth’s climate and to show that the influence of CO2 on atmospheric temperature is so small as to be negligible.
Lightfoot and Mamer, 2017

 

Leading Heat Transfer Physicists/Geologists Assert The Impact Of CO2 Emissions On Climate Is ‘Negligible’

The increasingly corroborated atmospheric mass pressure (gravity) explanation for variances in planetary temperatures – which precludes a significant role for CO2 concentration changes – has now advanced from peer-reviewed scientific journals to university-level textbooks.
The “adiabatic theory” of the greenhouse effect (adiabatic: “the constant decline in temperature of an air parcel as it rises in the atmosphere due to pressure drop and gas expansion”) is capable of explaining the variances in temperatures on planets like Earth, Mars, and Venus using each planet’s atmospheric pressure gradient – and without reliance on the traditional greenhouse effect theory that assigns a governing role to CO2.

 

New Paper: At Least 80% Of The Warming Over The Last Century Due To ‘Natural Phenomena’

“Even if there had been no industrial revolution and burning of fossil fuels, there would have still been warming through the twentieth century – to at least 1980, and of almost 1°C.” _Abbot and Marohasy, 2017
