Overview
- Sean Rush complains about an article What the climate-change collapse of critical Atlantic ocean system could mean for New Zealand published by Newshub on 2 March 2024. The complaint raises Media Council Principle (1) Accuracy, Fairness and Balance. The complaint is not upheld, with dissent.
The Article
- The article begins by stating that scientists have warned that a catastrophic collapse of a critical Atlantic Ocean current system is on the cards if human-induced climate change continues. It notes a 2021 study suggesting that this system is weaker than at any other time in the past 1600 years and refers to a new study which it says confirms “the Earth is on a bad path”.
- The article proceeds to explain the ocean system in question (the AMOC). Relevantly, it notes that scientists believe that the system has shut down in the past due to rapid glacial melt and that the new study’s findings warn that the system “… could soon tip into a shutdown again as freshwater floods the ocean due to ice melting from climate change”. It quotes New Zealand experts explaining what the recent study means and what impact the collapse of the AMOC might have in New Zealand.
- The article also notes that the study “does not give specific timeframes for when the potential collapse could happen, saying more research is needed”. However, it quotes one of the study’s author’s views that we can “at least say we are heading in the direction of the tipping point under climate change”.
The Complaint
- Sean Rush complains that it was inaccurate for the article to say that the recent study states that the AMOC “could soon tip into a shutdown”. He states that the recent study actually says:
Under increasing freshwater forcing, we find a gradual decrease … in the AMOC strength … Natural variability dominates the AMOC strength in the first 400 years; however, after model year 800, a clear negative trend appears because of the increasing freshwater forcing. Then, after 1750 years of model integration, we find an abrupt AMOC collapse …
- Mr Rush considers that this indicates that the model needs to be run for 1750 years before a shutdown arises. He considers Newshub’s reporting is alarmist and should be qualified to note that the model run time is 1750 years. He does not consider that use of the word “could” conveys the uncertainties (and total irrelevance) this study’s findings have to present and near day future New Zealand. He maintains that “This study shows that the model needs to be run for 1,750 years before a shut-down ‘could’ arise – this is clearly not ‘soon’ as that word is commonly understood by the target audience”. He considers that the reality is that any slowdown, if it happens, was modelled to start in 1750 years, at the earliest.
- We note that Newshub incorrectly thought Mr Rush was also complaining about another aspect of the article. Mr Rush has clarified that he is not and we do not discuss it further.
The Response
- The Warner Bros Discovery Standards Committee considered Mr Rush’s initial complaint and it relies on its response to that complaint for the purposes of this complaint to the Media Council. It does not consider there has been a breach of Media Council principles. It considers that the overall finding of the research is that a slow decline in AMOC could lead to a sudden collapse of the AMOC over less than 100 years, with calamitous consequences.
- The research does not put a timeframe on when this shift might occur. The word ‘soon’ is not a specific timeframe in the article and is also preceded by the word ‘could’. It did not categorically state the event would occur. As a result, the Newshub article was not inaccurate in the context of the research being reported on.
The Discussion
- This complaint falls to be decided under Media Council Principle (1) Accuracy, Fairness and Balance, which states:
Publications should be bound at all times by accuracy, fairness and balance, and should not deliberately mislead or misinform readers by commission or omission. In articles of controversy or disagreement, a fair voice must be given to the opposition view.
- It is important to note that the Media Council is in no position, and is not being asked to make any comment about the study in question or its accuracy. Rather, we must determine if the Newshub article accurately reports on the scientific paper which records the results of the recent study.
- That said, it is useful to briefly outline what the scientific paper does. Among other things:
a. It reports the results of a new computer simulated model aiming to predict how the AMOC will operate under different conditions. In this context, it starts with a steady state (reflecting a ‘preindustrial control’) and identifies the points at which change to the AMOC is observable in the model, using years as a measure of the time the model is ‘run’.
b. It identifies the time under the model where a collapse of the AMOC occurs. A tipping point can be seen to begin at around year 1750 of the model and the process continues over the next 100 years.
c. On the basis of the data provided by the model the authors attempt to identify a physics-based early warning indicator. The importance of this is that it might be used in the real world to predict when a tipping point might be coming.
d. It attempts to apply this model to the present-day real world AMOC, noting the data suggests it may be on course to tipping and that other studies conducted by different researchers, which suggest a tipping point could occur between real world 2025 and 2095 “could be accurate” (although this needed to be treated with some caution).
It follows that it is clear that the 1750 years referred to by Mr Rush is the point at which a shutdown was observable in the computer simulated model, which measures the passage of time in units of years from a non-real world steady state starting point. It is not saying that we can expect a shutdown 1750 years from today.
- However, we must still assess whether it was fair and accurate to describe the scientific paper as saying a tipping point could be reached soon. Overall, we think that the Newshub story was not well put together and does appear to take an unnecessarily alarmist tone. It reported on complex and nuanced science and we consider that real care ought to be taken when reporting on the results of this sort of study.
- However, we do not uphold this complaint because we consider that there is enough in the scientific paper to warrant a description of the research as suggesting a tipping point and shut down could be reached soon. Although the paper does not give specific time frames it does note, and comment on, other research that suggests the present-day AMOC is in its weakest state in over a millennium and approaches a tipping point “before the end of this century”. In part, this is used to justify the need for the research being presented as the authors say there is a need for a “more physics based, observable and reliable early warning indicators”. Importantly, it states that:
By analysing SST-based proxies of the MOC strength, it was suggested [in other cited research] that the real present-day AMOC approaches a tipping point … Because both variance and auto-correlation are increasing in the SST-based AMOC time series in [the other cited research] [that research’s] estimate of the tipping point (2025 to 2095, 95% confidence level) could be accurate.
- This indicates that the authors of the scientific paper consider that research by others suggesting a tipping point between 2025 and 2095 may be accurate, although they note some caveats.
- The ‘soon’ comment must also be read in the context of the whole Newshub article. Immediately before the comment is the observation that the AMOC shut down 12,000 years ago. Shortly after the comment is the statement that “The study adds to the growing body of evidence that the AMOC may be approaching a tipping point and that it could even be close”. As a result, while we accept that the word ‘soon’ will always be open to interpretation, we do not think it was inaccurate or unfair to report that the scientific paper suggests a tipping point could be reached soon. As noted by Warner Bros the scientific paper does indicate that once a tipping point is reached collapse could happen within 100 years. Moreover, the scientific paper indicates that the consequences could be felt very quickly. The paper also suggests that studies stating this could start between 2025 and 2095 may be accurate. On the basis of this research, it appears that a tipping point and the start of a shutdown could be, but may not, be reached soon.
- The complaint is not upheld with dissent.
Dissent by Jo Cribb:
In order to determine the accuracy of this article, the Council needed to read and interpret the complex scientific studies that it was
based on. These studies involve complex computational modelling and their findings are nuanced and come with many caveats. The
average reader of this article would not have gone to the source articles and even if they did would have found them exceptionally
technical.
There is no denying that climate change is one of the most pressing issues facing humanity. Reporting on emerging research is incredibly important.
However, this article is confusing, and potentially leads the readers to conclusions that are not solidly backed up by the research. Specifically, that the tipping point to climate shut down is 'soon' which an average reader could rightly suggest is this month, or this year, or next is not what the research states.
