No they don t
The authors of the studies used have come back quite pi@#ed their papers have been misquoted, purposley misinterpreted and taken out of context, to drive home a specific agenda.
The blogger has not read the papers he s cherry picked bits and peices to try to make his point. Below are some the authors response to the blog and yes braits
Misuse of their research
Tyler Jones, Research Associate, University of Colorado
The West Antarctica temperature plot that was pulled from my 2017 paper is very low resolution, and does not resolve the most recent few 100 yrs. We know from other studies that West Antarctica is currently warming faster than almost any other place on Earth. Furthermore, my paper has nothing to do with global warming or human activities. In fact, I only focus on time periods well before the Industrial Revolution. It is clear that global warming is caused predominantly by human activity.
Belinda Dechnik, The University of Sydney
My data does discuss sea surface temperature in the Great Barrier Reef being slightly warmer than present during the mid-Holocene in response to natural climate variability. However, I in no way deny that the current climate is warming, and that anthropogenic effects are proving very detrimental, particularly to reef systems. This article has misunderstood my findingsand in no way supports my view on climate change. I am very disturbed indeed that these people have used my article in such a way to try and discredit the serious effects of man-made climate change.
Nathan Steiger, Postdoctoral Fellow, Columbia University
The blog post maliciously tampered with figures from my paper, removing lines from the figures. My paper is just not relevant to the arguments about global warming.
R. Scott Anderson, Professor, Northern Arizona University
Although the curve shown in the Breitbart article supports our research, the specific curve cited is not our work, but comes instead from nearby tree-ring research done by Greg Wiles and his co-workers (2014). This is clearly stated in the figure caption in our article, which could have been seen if the article had been actually read. My conclusion from this is that Breitbart was not careful in its compilation, and for me this calls into question their methods for collecting data on other articles. Our conclusions are much more complex, and suggest that post-Little Ice Age warming has occurred, and has affected forests at higher elevations to a greater extent than at lower elevations.
Yair Rosenthal, Professor, Rutgers University
The data were taken out of context. In fact a previous article (Rosenthal et al., 20013) made the argument that the current warming, as measured by the increase in Ocean Heat Content (OHC), is a reversal of the long-term cooling trend in the preceding centuries and the rate of heat gain is substantially higher than recorded in the past. If anything, these data support global warming as manifested by the recent increase in OHC.
Normunds Stivrins, Associate Professor, University of Helsinki
Our article (Stivrins et al., 2017, The Holocene) focuses on other subjects than human-induced impacts (climate change). It’s sad that the blogger did not understand what this study is about, but rather took a sentence without context. Our point was that geological aspects can protect glacial ice in the ground but it starts to melt when air temperature increases—in this case when temperature started to increase above today’s temperatures. Note that this is a specific case study where exceptional environmental conditions prevail 8,400-7,400 years ago in western Latvia.
Bradley Markle, PhD Candidate, University of Washington
My study, and almost all I saw mentioned in 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 give context to recent climate changes. 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.
I do not argue that “global warming… is a fake artefact [sic]”. The overwhelming scientific evidence is that the climate is currently changing and that human influences, primarily releasing CO2 into the atmosphere, have a significant impact. Though, again, this is not at all addressed in my study, nor any of the ones quoted that I recognized (though I did not read them all).
The blog post and Breitbart article are both misleading and inaccurate, on several levels.
Ernesto Tejedor Vargas, University of Zaragoza
The article Tejedor et al., 2017 is not a climate-change-denying paper. It is a paleoclimate paper showing, first, a new maximum temperature reconstruction for the last 400 years (including the current warming) and second, a new standardization method in dendrochronology to remove the non-climatic trend.
The image in the post does not by any means reflect the message of the paper. That figure is the raw temperature of the CRU dataset in the region, i.e., [I would like the author of the No Tricks Zone post to] remove my name from the blog since it is not reflecting our research conclusion.
David Reynolds, Postdoctoral Research Associate, Cardiff University (and co-authors)
The article uses Figure 11 from Reynolds et al., 2017 without displaying the figure caption. The caption for this figure clearly states that the data shown have been detrended using a simple linear function in order to highlight the high-frequency (sub-centennial) mean annual sea surface temperature (SST) anomalies. This means we have statistically removed the long-term trend, i.e., the 20th century warming signal. The long-term trend was removed from the observational SST data as the particular proxy data being used for comparison, the marine bivalve growth increment width (GIW), does not record the low frequency change, such as the long-term warming trend. The reason the GIW chronology doesn’t record the long-term trend is because there are changes in the growth rates of the bivalves as they age (older=slower=thinner GIW). The standard procedure (e.g. Butler et al., 2009) for taking these so-called “ontogenetic effects” into account removes the ability of the GIW proxy to record long-term trends while retaining the signal of high-frequency variability. Looking at the non-detrended observational SST data (Fig 1) clearly shows there is a long-term warming trend over the 20th century in northeast Atlantic sea surface temperatures.
Fig 1 — The black line shows mean annual sea surface temperatures over the North East Atlantic (50-60oN by 10-0oW). The dashed black line shows the linear trend over the 20th century. The data shown here are the raw data that were then linear detrended for use in Reynolds et al., 2017 Fig 11.
