80 Graphs From 58 New (2017) Papers Invalidate Claims Of Unprecedented Global-Scale Modern Warming

Scientists Increasingly Discarding

‘Hockey Stick’ Temperature Graphs

“[W]hen it comes to disentangling natural variability from anthropogenically affected variability the vast majority of the instrumental record may be biased.”  — Büntgen et al., 2017


Last year there were at least 60 peer-reviewed papers published in scientific journals demonstrating that Today’s Warming Isn’t Global, Unprecedented, Or Remarkable.
 .
Just within the last 5 months, 58 more papers and 80 new graphs have been published that continue to undermine the popularized conception of a slowly cooling Earth temperature history followed by a dramatic hockey-stick-shaped uptick, or 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.
 .
Succinctly, then, scientists publishing in peer-reviewed journals have increasingly affirmed that there is nothing historically unprecedented or remarkable about today’s climate when viewed in the context of long-term natural variability.


Büntgen et al., 2017

“Spanning the period 1186-2014 CE, the new reconstruction reveals overall warmer conditions around 1200 and 1400, and again after ~1850.
Little agreement is found with climate model simulations that consistently overestimate recent summer warming and underestimate pre-industrial temperature changes. … [W]hen it comes to disentangling natural variability from anthropogenically affected variability the vast majority of the instrumental record may be biased.

“The Global Historical Climatology Network (GHCN) v2 temperature time series (GISS Surface Temperature Analysis, 2012) in Alice Spring and all the 36 other stations located in a circle of 1,000 km from Alice Spring do not show any warming. There are stations covering different time windows having very close patterns of temperatures. In this circle of 3,141,593 km2 (roughly 50% of Australia) that is mostly underdeveloped, none of the stations […] has a warming trend.  … It is therefore only an artefact by BOM to produce the warming. Homogenization is supposed to be used to account for upwards biases such as Urban Heat Island, not to introduce upwards biases.  …  In the centre of Australia, all the stations available in a circle of radius 1,000 km were showing very little or no warming, as still acknowledged in the GHCN v2 data set up to October 2011 (Fig. 6). … Table 1 presents the warming trend for the 30 longest temperature records of Australia collected in a single location, with measurements started before 1900 and continued until after 1985.  … In the 30 locations, the monthly mean maximum temperature is warming 0.0004°C/year, or 0.04°C/century. That means there is no change within the limits of accuracy of the measurements. … The climate trend maps compiled by Bureau of Meteorology in their climate change section are completely unreliable, as the alleged increasing temperature is obtained by lowering temperatures of the past by “adjustments”. The longest of the Australian temperature records that were considered the most reliable by Bureau of Meteorology on February 2009 (BOM 2009) are still available as raw temperatures in the climate data online section and consistently show no warming and no increased extreme events within the limit of accuracy of measurements.”

The transition from warm to colder climatic conditions occurs around 1300 CE associated with the Wolf solar minimum. The coldest SSTs are detected between 1350 and 1850 CE, on Iberia during the well-known Little Ice Age (LIA) (Bradley and Jones, 1993), with the most intense cooling episodes related with other solar minima events, and major volcanic forcing and separated by intervals of relative warmth (e.g. (Crowley and Unterman, 2013; Solanki et al., 2004; Steinhilber et al., 2012; Turner et al., 2016; Usoskin et al., 2011). During the 20th century, the southern records show unusually large decadal scale SST oscillations in the context of the last 2 millennia, in particular after the mid 1970’s, within the Great Solar Maximum (1940 – 2000 (Usoskin et al., 2011)) and the “greater salinity anomaly” event in the northern Atlantic (Dickson et al., 1988), or yet the higher global temperatures of the last 1.4 ky detected by (Ahmed et al., 2013).”

Deng et al., 2017

The results indicate that the climate of the Medieval Climate Anomaly (MCA, AD 900–1300) was similar to that of the Current Warm Period (CWP, AD 1850–present) … As for the Little Ice Age (LIA, AD 1550–1850), the results from this study, together with previous data from the Makassar Strait, indicate a cold and wet period compared with the CWP and the MCA in the western Pacific. The cold LIA period agrees with the timing of the Maunder sunspot minimum and is therefore associated with low solar activity.”


Chapanov et al., 2017

“A good agreement exists between the decadal cycles of LOD [length of day], MSL [mean sea level], climate and solar indices whose periods are between 12-13, 14-16, 16-18 and 28-33 years.”


Williams et al., 2017

“Reconstructed SSTs significantly warmed 1.1°C … from 1660s to 1800 (rate of change: 0.008°C/year), followed by a significant cooling of 0.8°C …  until 1840 (rate of change: 0.02°C/year), then a significant warming of 0.8°C from 1860 until the end of reconstruction in 2007 (rate of change: 0.005°C/year).” [The amplitude of sea surface temperature warming and cooling was higher and more rapid from the 1660s to 1800 than from 1860-2007.]
‘In fact, the SST reconstruction significantly co-varied with a reconstruction of solar irradiance [Lean, 2000] on the 11-year periodicity only from ~1745 to 1825. In addition, the reconstructed SSTs were cool during the period of lower than usual solar irradiance called the Maunder minimum (1645–1715) but then warmed and cooled during the Dalton minimum (1795–1830), a second period of reduced solar irradiance. … The Dalton solar minimum and increased volcanic activity in the early 1800s could explain the decreasing SSTs from 1800 to 1850.”


Stenni et al., 2017

“A recent effort to characterize Antarctic and sub-Antarctic climate variability during the last 200 years also concluded that most of the trends observed since satellite climate monitoring began in 1979 CE cannot yet be distinguished from natural (unforced) climate variability (Jones et al., 2016), and are of the opposite sign [cooling, not warming] to those produced by most forced climate model simulations over the same post-1979 CE interval. … (1) Temperatures over the Antarctic continent show an overall cooling trend during the period from 0 to 1900CE, which appears strongest in West Antarctica, and (2) no continent-scale warming of Antarctic temperature is evident in the last century.”

“After the 8.2 ka event, Greenland temperature reached the Holocene thermal maximum with the warmest decades occurring during the Holocene (2.9 ± 1.4 °C warmer than the recent decades) at 7960 ± 30 years B.P. … For the most recent 10 years (2005 to 2015), apart from the anomalously warm year of 2010, mean annual temperatures at the Summit exhibit a slightly decreasing trend in accordance with northern North Atlantic-wide cooling. The Summit temperatures are well correlated with southwest coastal records (Ilulissat, Kangerlussuaq, Nuuk, and Qaqortoq).”

“The main driving forces behind the Holocene climatic changes in the LYR [Lower Yangtze Region, East China] area are likely summer solar insolation associated with tropical or subtropical macro-scale climatic circulations such as the Intertropical Convergence Zone (ITCZ), Western Pacific Subtropical High (WPSH), and El Niño/Southern Oscillation (ENSO).”


Larsen et al., 2017

[K]nowledge remains sparse of GICs [glaciers and ice caps] fluctuations in Greenland and whether they survived past warmer conditions than today, e.g. the Holocene Thermal Maximum (HTM) ~8-5 cal. ka BP and the Medieval Climate Anomaly (MCA) ~1200-950 C.E. Only a few available studies have provided continuous records of Holocene glacier fluctuations in east Greenland (Lowell et al., 2013; Levy et al., 2014; Balascio et al., 2015) and west Greenland (Schweinsberg et al., 2017). These records show that local GICs [glaciers and ice caps] were significantly reduced and most likely completely absent during the HTM [Holocene Thermal Maximum].”

“Our analyses reveal appreciable and stable positive correlation between summer temperatures in Northern Fennoscandia and sea surface temperature in North Atlantic over AD 1567–1986. Thus a connection between climates of Northern Fennoscandia and North Atlantic basin is established for more than the last four centuries. Significant correlation was found between SST [sea surface temperatures] in NA [the North Atlantic] and solar activity (both instrumental data and proxies) during AD 1716–1986. … Thus, the connection between Northern Fennoscandian climate and solar activity, which has been previously established at century-scale (Ogurtsov et al., 2001, 2002, 2013) and millennial-scale (Helama et al., 2010), is confirmed for AD 1716–1986 over the entire frequency range using unfiltered records (with the exception for AMO reconstruction after Mann et al. (2009)).”


Arppe et al., 2017

“The highest δ18O [temperature proxy] value of the record occurs at ca. 1900–1800 cal. yr BP (~50–150 CE), coinciding with a period of general warmth referred to as the Roman Warm Period (RWP). In the North Atlantic Ocean, the RWP interval (ca. 2500–1500 cal. yr BP) is associated with, for example, increased temperatures and productivity, decreased evidence of ice … Northern Hemisphere terrestrial environments widely display evidence of elevated temperatures between 1 and 300 CE (Ljungqvist, 2010). … southern Spitsbergen experienced a significant late-Holocene cold spell prior to the onset of the LIA [Little Ice Age]. These negative shifts overlap with the latter part of a cooling known as the Dark Ages Cold Period (DACP, ca. 1500–1000 cal. yr BP; Bianchi and McCave, 1999; McDermott et al., 2001). The event is directly preceded by a minimum in total solar irradiation (Renssen et al., 2006; Steinhilber et al., 2009) … A wealth of proxy evidence testifies to the LIA [Little Ice Age] cooling, thought to have been triggered by reduced solar irradiance, extended volcanism, and internal characteristics of the ocean–atmosphere system (Miller et al., 2010, 2012; Wanner et al., 2011). … Factoring in respective age-model uncertainties, it appears that all major negative shifts, that is, ‘cold’ periods, in the δ18Olw record are roughly synchronous with periods of major negative anomalies in total solar irradiation and high modeled probabilities for extremely cold years in the Nordic Seas (Renssen et al., 2006), and widespread evidence of North Atlantic ‘cold spells’ (Bond et al., 2001; Sarnthein et al., 2003; Solomina et al., 2015; Wanner et al., 2008) linked to solar forcing.”

Rosenthal et al., 2017

“Here we review proxy records of intermediate water temperatures from sediment cores and corals in the equatorial Pacific and northeastern Atlantic Oceans, spanning 10,000 years beyond the instrumental record. These records suggests that intermediate waters [0-700 m] were 1.5-2°C warmer during the Holocene Thermal Maximum than in the last century. Intermediate water masses cooled by 0.9°C from the Medieval Climate Anomaly to the Little Ice Age. These changes are significantly larger than the temperature anomalies documented in the instrumental record. The implied large perturbations in OHC and Earth’s energy budget are at odds with very small radiative forcing anomalies throughout the Holocene and Common Era. … The records suggest that dynamic processes provide an efficient mechanism to amplify small changes in insolation [surface solar radiation] into relatively large changes in OHC.”


Li et al., 2017

“We suggest that solar activity may play a key role in driving the climatic fluctuations in NC [North China] during the last 22 centuries, with its quasi ∼100, 50, 23, or 22-year periodicity clearly identified in our climatic reconstructions. … It has been widely suggested from both climate modeling and observation data that solar activity plays a key role in driving late Holocene climatic fluctuations by triggering global temperature variability and atmospheric dynamical circulation

“2003– 2009 was the warmest period in the reconstruction. 1970– 2000 was colder than the last stage of the Little Ice Age (LIA).”


Köse et al., 2017

“The reconstruction is punctuated by a temperature increase during the 20th century; yet extreme cold and warm events during the 19th century seem to eclipse conditions during the 20th century. We found significant correlations between our March–April spring temperature reconstruction and existing gridded spring temperature reconstructions for Europe over Turkey and southeastern Europe. … During the last 200 years, our reconstruction suggests that the coldest year was 1898 and the warmest year was 1873. The reconstructed extreme events also coincided with accounts from historical records. …  Further, the warming trends seen in our record agrees with data presented by Turkes and Sumer (2004), of which they attributed [20th century warming] to increased urbanization in Turkey.”


Flannery et al., 2017

The early part of the reconstruction (1733–1850) coincides with the end of the Little Ice Age, and exhibits 3 of the 4 coolest decadal excursions in the record. However, the mean SST estimate from that interval during the LIA is not significantly different from the late 20th Century SST mean. The most prominent cooling event in the 20th Century is a decade centered around 1965. This corresponds to a basin-wide cooling in the North Atlantic and cool phase of the AMO.”


Steiger et al., 2017

“Through several idealized and real proxy experiments we assess the spatial and temporal extent to which isotope records can reconstruct surface temperature, 500 hPa geopotential height, and precipitation. We find local reconstruction skill to be most robust across the reconstructions, particularly for temperature and geopotential height, as well as limited non-local skill in the tropics.  These results are in agreement with long-held views that isotopes in ice cores have clear value as local climate proxies, particularly for temperature and atmospheric circulation.”




Mangerud and Svendsen, 2017

“Shallow marine molluscs that are today extinct close to Svalbard, because of the cold climate, are found in deposits there dating to the early Holocene. The most warmth-demanding species found, Zirfaea crispata, currently has a northern limit 1000 km farther south, indicating that August temperatures on Svalbard were 6°C warmer at around 10.2–9.2 cal. ka BP, when this species lived there. … After 8.2 cal. ka, the climate around Svalbard warmed again, and although it did not reach the same peak in temperatures as prior to 9 ka, it was nevertheless some 4°C warmer than present between 8.2 and 6 cal. ka BP. Thereafter, a gradual cooling brought temperatures to the present level at about 4.5 cal. ka BP. The warm early-Holocene climate around Svalbard was driven primarily by higher insolation and greater influx of warm Atlantic Water, but feedback processes further influenced the regional climate.”


Lasher et al., 2017

“This paper presents a multi proxy lake record of NW Greenland Holocene climate. … Summer temperatures (2.5–4 °C warmer than present) persisted until 4 ka [4,000 years ago] … Continual cooling after 4 ka led to coldest temperatures after 1.2 ka, with temperature anomalies 2-3°C below present.  Approximately 1000 km to the south, a 2-3°C July temperature anomaly (relative to [warmer than] present) between 6 and 5 ka was reported based upon chironomid assemblages near Illulisat and Jakobshavn (Axford et al., 2013). Across Baffin Bay on northeastern Baffin Island, HTM summer temperatures were an estimated ~5°C warmer than the pre-industrial late Holocene and 3.5°C warmer than present, based upon chironomid assemblages (Axford et al., 2009; Thomas et al., 2007). … Following deglaciation, the GrIS [Greenland Ice Sheet] retreated behind its present margins (by as much as 20-60 km in some parts of Greenland) during the HTM [Holocene Thermal Maximum] (Larsen et al., 2015; Young and Briner, 2015).”

Chang et al., 2017

“The chironomid-based record from Heihai Lake shows a summer temperature fluctuation within 2.4°C in the last c. 5000 years from the south-east margin of the QTP [Qinghai–Tibetan Plateau]. … The summer temperature changes in this region respond primarily to the variation in the Asian Summer Monsoon. The variability of solar activity is likely an important driver of summer temperatures, either directly or by modifying the strength and intensity of the Indian Ocean Summer Monsoon. … We observed a relatively long-lasting summer cooling episode (c. 0.8°C lower than the 5000-year average) between c. 270 cal. BP and AD c. 1956. … The record shows cooling episodes occurred at c. 3100, 2600, 2100 and 1600 cal. BP.  This is likely related to the period defined as the Northern Hemisphere Little Ice Age (LIA; c. AD 1350–1850, equivalent to 600–100 cal. BP). These possibly relate to the 500-year quasi-periodic solar cycle. Cooling stages between c. 270 and 100 cal. BP were also recorded and these are possibly linked to the LIA suggesting a hemisphere-wide forcing mechanism for this event.”

Growing paleoclimatic evidence suggests that the climatic signals of Medieval Warm Period and the Little Ice Age events can be detected around the world (Mayewski et al., 2004; Bertler et al., 2011). … [T]he causes for these events are still debated between changes in solar output, increased volcanic activity, shifts in zonal wind distribution, and changes in the meridional overturning circulation (Crowley, 2000; Hunt, 2006).”

The last ca. 1000 years recorded the warmest SST averaging 28.5°C. We record, for the first time in this region, a cool interval, ca. 1000 years in duration, centered on 5000 cal years BP concomitant with a wet period recorded in Borneo. The record also reflects a warm interval from ca. 1000 to 500 cal years BP that may represent the Medieval Climate Anomaly. Variations in the East Asian Monsoon (EAM) and solar activity are considered as potential drivers of SST trends. However, hydrology changes related to the El Nino-Southern Oscillation (ENSO) variability, ~ shifts of the Western Pacific Warm Pool and migration of the Intertropical Convergence Zone are more likely to have impacted our SST temporal trend. …  The SA [solar activity] trends (Steinhilber et al., 2012) are in general agreement with the regional cooling of SST (Linsley et al., 2010) and the SA [solar activity] oscillations are roughly coincident with the major excursions in our SST data.”


Koutsodendris et al., 2017

“Representing one of the strongest global climate instabilities during the Holocene, the Little Ice Age (LIA) is marked by a multicentennial-long cooling (14-19th centuries AD) that preceded the recent ‘global warming’ of the 20th century. The cooling has been predominantly attributed to reduced solar activity and was particularly pronounced during the 1645-1715 AD and 1790-1830 AD solar minima, which are known as Maunder and Dalton Minima, respectively.”

“Our findings are generally consistent with other records from the ISM [Indian Summer Monsoon]  region, and suggest that the monsoon intensity is primarily controlled by solar irradiance on a centennial time scale. This external forcing may have been amplified by cooling events in the North Atlantic and by ENSO activity in the eastern tropical Pacific, which shifted the ITCZ further southwards.”


Wu et al., 2017

“The existence of depressed MAAT [mean annual temperatures] (1.3°C lower than the 3200-year average) between 1480 CE and 1860 CE (470–90 cal. yr BP) may reflect the manifestation of the ‘Little Ice Age’ (LIA) in southern Costa Rica. Evidence of low-latitude cooling and drought during the ‘LIA’ has been documented at several sites in the circum-Caribbean and from the tropical Andes, where ice cores suggest marked cooling between 1400 CE and 1900 CE.  Lake and marine records recovered from study sites in the southern hemisphere also indicate the occurrence of ‘LIA’ cooling. High atmospheric aerosol concentrations, resulting from several large volcanic eruptions and sea-ice/ocean feedbacks, have been implicated as the drivers responsible for the ‘LIA’.”


Park, 2017

Late Holocene climate change in coastal East Asia was likely driven by ENSO variation.   Our tree pollen index of warmness (TPIW) shows important late Holocene cold events associated with low sunspot periods such as Oort, Wolf, Spörer, and Maunder Minimum. Comparisons among standard Z-scores of filtered TPIW, ΔTSI, and other paleoclimate records from central and northeastern China, off the coast of northern Japan, southern Philippines, and Peru all demonstrate significant relationships [between solar activity and climate]. This suggests that solar activity drove Holocene variations in both East Asian Monsoon (EAM) and El Niño Southern Oscillation (ENSO).”

Warm periods (modern T[emperatures] July or higher) were reconstructed for the periods between ca 2700 and 1800 cal yr BP, 1500 and 1300 cal yr BP and after 150 cal yr BP.”

Li et al., 2017

“Contrary to the often-documented warming trend over the past few centuries, but consistent with temperature record from the northern Tibetan Plateau, our data show a gradual decreasing trend of 0.3 °C in mean annual air temperature from 1750 to 1970 CE. This result suggests a gradual cooling trend in some high altitude regions over this interval, which could provide a new explanation for the observed decreasing Asian summer monsoon. In addition, our data indicate an abruptly increased interannual-to decadal-scale temperature variations of 0.8 – 2.2 °C after 1970 CE, in terms of both magnitude and frequency, indicating that the climate system in high altitude regions would become more unstable under current global warming.”

Pendea et al., 2017  (Russia)

The Holocene Thermal Maximum (HTM) was a relatively warm period that is commonly associated with the orbitally forced Holocene maximum summer insolation (e.g., Berger, 1978; Bartlein et al., 2011). Its timing varies widely from region to region but is generally detected in paleorecords between 11 and 5 cal ka BP (e.g., Kaufman et al., 2004; Bartlein et al., 2011; Renssen et al., 2012).  … In Kamchatka, the timing of the HTM varies. Dirksen et al. (2013) find warmer-than-present conditions between 9000 and 5000 cal yr BP in central Kamchatka and between 7000 and 5800 cal yr BP at coastal sites.”

Stivrins et al., 2017  (Latvia)

“Conclusion: Using a multi-proxy approach, we studied the dynamics of thermokarst characteristics in western Latvia, where thermokarst occurred exceptionally late at the Holocene Thermal Maximum. …  [A] thermokarst active phase … began 8500 cal. yr BP and lasted at least until 7400 cal. yr BP. Given that thermokarst arise when the mean summer air temperature gradually increased ca. 2°C beyond the modern day temperature, we can argue that before that point, the local geomorphological conditions at the study site must have been exceptional to secure ice-block from the surficial landscape transformation and environmental processes.”

Bañuls-Cardona et al., 2017  (Spain)

“During the Middle Holocene we detect important climatic events. From 7000 to 6800 [years before present] (MIR 23 and MIR22), we register climatic characteristics that could be related to the end of the African Humid Period, namely an increase in temperatures and a progressive reduction in arboreal cover as a result of a decrease in precipitation. The temperatures exceeded current levels by 1°C, especially in MIR23, where the most highly represented taxon is a thermo-Mediterranean species, M. (T.) duodecimcostatus.”

Reid, 2017 (Global)

The small increase in global average temperature observed over the last 166 years is the random variation of a centrally biased random walk. It is a red noise fluctuation. It is not significant, it is not a trend and it is not likely to continue.”

Åkesson et al., 2017 (Norway)

“Reconstructions for southern Norway based on pollen and chironomids suggest that summer temperatures were up to 2 °C higher than present in the period between 8000 and 4000 BP, when solar insolation was higher (Nesje and Dahl, 1991; Bjune et al., 2005; Velle et al., 2005a).”

Molnár and Végvári, 2017 (SE Central Europe)

“Our study provides an estimate for the value of MAT of HTM of Pannon region with an interval of 0.4°C, relying on macroecological considerations. We calculate the temperature of the HTM [Holocene Thermal Maximum] 1.3–1.7°C warmer than the present temperature.”

Lusas et al., 2017 (East Greenland)

“The lack of glacio-lacustrine sediments throughout most of the record suggests that the ice cap was similar to or smaller than present throughout most of the Holocene. This restricted ice extent suggests that climate was similar to or warmer than present, in keeping with other records from Greenland that indicate a warm early and middle Holocene. Middle Holocene magnetic susceptibility oscillations, with a ~200-year frequency in one of the lakes, may relate to solar influence on local catchment processes. … Air temperatures in Milne Land, west of our study area, based on preliminary estimates from chironomids, may have been 3–6°C warmer than at present (Axford et al. 2013), and in Scoresby Sund itself, warm ocean fauna, including Mytilus edulis and Chlamys islandica, both of which live far to the south today, occupied the fjords (Sugden and John 1965; Hjort and Funder 1974; Street 1977; Funder 1978; Bennike and Wagner 2013; Fig. 13).  … Recession of Istorvet ice cap in the last decade has revealed plant remains that show that the glacier was smaller than at present during the early stages of the Medieval Warm Period, but expanded during the late Holocene ca. AD 1150 (Lowell et al. 2013).”

The issue was calculating LW absorption at the ocean surface.It is governed by the laws of radiation transport, not by what is happening in the deep ocean.The consequences to the deep ocean temperature is another matter, and is governed by the laws of convective heat transfer.Moderator:This is not duplicate comment!

    The “Climate Change” supporters are targeting a symptom, not the disease. The sickness the Earth has is Global Pollution, not “climate change.” A change in climate could be only one possible symptom of a polluted earth, but it doesn’t have to be. I can dump tons of toxic chemicals in your nearest lake or river without ever changing the temperature of the earth at all. The fact that Global Climate change supporters are not addressing the real problem (pollution) head-on, (a problem that should be obvious to any scientist), tells me they are doing all of it for their own selfish benefit. That is, to tax the world and make a profit.

    The principal indicators that warmists use is the correlation between CO2 levels and temperature.

    Where their arguments fall apart is that it appears that CO2 rises lag behind temperature rise.

    Why does nobody address this issue thoroughly to discredit the warmists?

    Citing this post, James Delingpole informs Breitbart Readers:

    “Global warming” is a myth — so say 80 graphs from 58 peer-reviewed scientific papers published in 2017.

    In how many of the 58 papers you cite can any such phrase as:

    “Global waming” is a myth” be found ?

    if it does not, whay have you not posted a correction to

    http://www.breitbart.com/big-government/2017/06/06/delingpole-global-warming-is-myth-58-scientific-papers-2017/ ?

    Climate scientists, including myself, have experimentaly detrermined that Delingpole’s Breitbart column rejects, censors or quickly removes critical
    comments from us, so it’s up to you to defend yourself in this matter.

    1. AndyG55

      You could of course attempt to prove it is NOT a myth.

      There is NO CO2 warming signature in the whole of the satellite data record.

      The ONLY warming has come from EL Nino and ocean effects, NEITHER of which is in any way affected by CO2

      We await your proof that it is NOT a myth.

      Proof that CO2 causes warming in a convective atmosphere or causes warming of oceans has so far been absolutely ZERO.

    Congratulations. This post (and Deller’s) has made Snopes.

    http://www.snopes.com/scientific-papers-global-warming-myth/

    On 6 June 2017, Breitbart News ran an article titled “‘Global Warming’ Is a Myth, Say 58 Scientific Papers in 2017”. This article, which is in essence merely a link to a post from a blog that goes by the name “No Tricks Zone” and some added musings on “grant-troughing scientists,” “huxter politicians,” “scaremongering green activists,” and “brainwashed mainstream media environmental correspondents,” claims that this ragtag collection of studies proves that the long-standing scientific consensus on climate change is nothing but a myth.

    The blog post Breitbart linked to is a list of 80 graphs (so many graphs!) taken from 58 studies. The analysis of the findings presented by No Tricks Zone is crude, misinformed, and riddled with errors.

    —–

    They have some good points, e.g.:

    This was the case for University of Washington PhD candidate Bradley Markle, whose paper (“Global Atmospheric Teleconnections During Dansgaard-Oeschger Events”) was also included in the No Tricks Zone:

    My study, and almost all I saw mentioned on the blog post, are studies of climate change in the past. My study investigates connections between different parts of the climate system during climate events that happened over 10,000 years ago. Studying climate change in the past can provide context for recent climate change. However, my study in no way investigates or tries to attribute the causes of recent climate change. It does not deal with human influences on climate at all.

      Similar fault as “Thinking port” fakers linked below:
      You trust an ex-prostitute outlet Snopes ? Snopes is an archetype of fake news, at least half of their rulings are politically driven false claims, the prostitute that works now as a presstitute… And so more and more they cry “fake news” at others, in order to obscure – such as “thief calls: catch the thief”…
      That Snopes claims something, you can be at least 50% sure it is false and just opposite. (Or is it only about their claims that make it to the opposing media?)

      —–
      So the scientist says, that “I say NOTHING about Climate change being of human origin”. Well. Neither do others.

      As an independent climate scientist, I am happy to see most charts here:
      There IS a Climate Change ongoing now.

      There ALWAYS is a Climate change ongoing, since there is nothing stable about the climate, and never was…
      The current climate change is in no way unexceptional, is still very far from harmful, and is absolutely not caused by CO2, since:

      CO2 levels depend on temperature (oceans releasing CO2 with it’s solubility depending on temperature),

      but 1000x stronger green-house effect has WATER, the changing structure of clouds. Change of proportion of Cirrus clouds has very profound effect on temperature, that is far above and beyond of any possible effect of CO2.

      It is a pitty, that ISCCP cloud structure datasets are poisoned with unreal “fixes“, that completely preclude studying long-term changes (like a step and completely unreal almost 2°C increase in middle-cloud temperature just at september 2001). It is a pitty, that SST dataset is poisoned with similar unreal “fix” of step increase at 1998, but they at least explain, that ratio of buoys and ships changes over time, with satelite measurements scarce, and buoy measures real surface temperature but ship stirrs waters, so their measurements differ and need to be “adjusted” for computing… (Or was it so strong el-Nino that it’s effects are permanent?)

      Since I believe the climate change is mostly attributed to higher amount of cirrus-type clouds (letting Solar radiation down but not letting reflected IR radiation out – surely you know which days and nights are most warm… And nights on Sahara are very cold, because there is no water in the air…) It partially depends on antropogenic factors, on air travel *trails and possibly on industry dust polution (not CO2)… But politicians would be much more reluctant to reduce air travelling, wont’t they ?

      Higher levels of CO2 are very profitable for plants and twice or three times current levels of CO2 would be extremely profitable for feeding the hungry regions of the planet. CO2 is the Green-allowing gas, in the best possible sense of that “Green”, it’s like a manna for all plants…
      http://www.naturalnews.com/2017-06-06-trump-just-saved-america-from-the-disastrous-paris-climate-treaty-fraud.html

      Otherwise if there is such a huge change in peer-reviewed papers, it does not show the climate changed, or that the scientists changed opinion, but it shows, that peer-review process has changed it’s position, allowing some former dissidents’ voices be heard…

      The Paris climate deal was hugest ever financial tunnel : the industry of developed countries shall pay $100 billion a year, so that africans and inds can buy from _jews_ building of “clean energy” power plants… Guess, who will profit most ? And why such a huge crying, that Trump said: “No!” ?
      (The exploit patterns are changing. (((They))) now devised, that exploiting developing countries in Africa is much less profitable, than _helping_ developing countries in Africa and elsewhere based on Euro-American expense, the infrastructure will be built for the needy, while money will pour to the right coffers… Do you dare to oppose? All those bought by the profiteers, and the unfledged youth deformed by bought academia, will aim to destroy you! )

    Steve someone asked if CO2 isn’t causing GW what is.

    The warming that ended the LIA is of unknown origin and didn’t follow a rise in CO2…..CO2 rise lagged that warming by 800years.

    THIS insignificant warming can’t just be attributed to CO2 when it’s not known what precipitated THAT warming except that it WASN’T CO2.

    In the 1970s the world was obsessing about the ‘coming ice age’…some of the very same scientists who want us terrified of CAGW…but that soon disappeared when a completely natural event called the Great Pacific Climate Shift occurred and world temperature had an upward step shift.

    Then another upward step shift occurred with the all-natural uber-El Nino of 1998…and world temperature was on a new plateau.

    Since then pretty much nothing….so the trend is TINY and all natural.

    Any warming from CO2 is logarithmic and of diminishing effect is it not?

    Hence the ongoing PAUSE admitted by IPCC AR5…along with many other AR5 admissions that are now ignored …like no increase in strength or frequency of severe weather events….no ACCELERATION in SLR.
