A few hours after "finishing" this edition of New Research, Nature Communications published a reassessment of SLR-driven coastal flooding hazards, New elevation data triple estimates of global vulnerability to sea-level rise and coastal flooding by Kulp & Strauss. The authors identify systematic problems with Shuttle Radar Topographic Mission (SRTM) DEM (digital elevation model) data and DEM products based on the SRTM data product. This family of DEM products support key inputs into estimates of human populations and cultural features at risk from increased coastal flooding due to SLR. Given that Kulp & Strauss are proposing a substantial difference in affected population, we can be sure that this work will be closely attended not only in the popular press but by other researchers studying the same subject.
In their article The truth is not in the middle”: Journalistic norms of climate change bloggers, Christel W. van Eck and coauthors examine practices of climate change bloggers, comparing climate blogosphere journalism to more traditional news media. From the article introduction in Global Environmental Change:
The results show that climate change bloggers support the traditional journalistic norms of personalization, dramatization, novelty, authority and order, but not balance. Beyond the traditional journalistic norms, climate change bloggers identify contextualization, clarity, decency, and particularly truth as important journalistic norms. Truth is understood as a multi-dimensional norm comprising objectivity, transparency, and honesty. No differences are identified between norms supported by climate sceptical and climate mainstream bloggers, but each group operationalizes the norms differently.
The paper features many ships, crew and cargo familiar to those plying the climate blogging ocean. Beyond the immediate research results, the paper's backgrounding discussion is a fascinating look into a feature of human culture created almost entirely as a incidental effect of policy friction introduced by entrenched industrial interests. We're reminded by this article of how climate blogging has traditionally been most centrally concerned with arguing over the equivalent validity of "2+2=4," with a tiny but dedicated group of variously motivated self-described iconoclasts dissipating energy, patience and time otherwise better employed elsewhere.
A difference between traditional journalism and what we read in blogs emerges in van Eck et al: blog authors are less attached to the notion of "balance" as an overriding objective. In particular, we read that for bloggers not trading in science fiction, defying the laws of physics by attempting to synthesize "balance" where it cannot be found is subordinated to slavish devotion to reality.
We can also see that there's certainly more than a little dark absurdity woven into the fabric of the climate blogging world; quoted in the paper, Peter Sinclair is barely attaining hyperbole when he remarks “If one side of the issue is that the sky is blue and the other side of the issue is the sky is purple with pink polka dots, those are not two sides that deserve equal weight.” To be having the discussion implied by Sinclair's analogy is tragicomic but he's not really exaggerating the weird parameters of the conversation. There's no turning down the responsibility to counter comically silly arguments when those arguments pose a serious threat to obviously necessary changes and hence more or less we're all made fools, unavoidably.
Swerving over to what might be termed "operational journalism," in Reporting on climate change by broadcast meteorologists: A national assessment Kristin Tim et al report on television meteorologists' experiences and expectations of communicating climate change matters to their audiences, in the Bulletin of the American Meteorological Society. The paper denotes solid progress in this area, with broadcast meteorologists better equipped to communicate this important topic to viewers and increasingly doing so.
A particularly interesting finding is that compared to their reportage a decade or more ago, broadcasters both fear this communication job less and do indeed find little reason to worry about negative feedback from viewers. Even so, a proportion of personalities still feel impelled to shrink back:
Most weathercasters who had reported about climate change on air indicated they received either positive viewer feedback or little feedback (61.9%); conversely, weathercasters who had not reported about climate change expected to receive mostly negative feedback (44.2%).
Cranky remarks about climate change have long been a conspicuous feature in newspaper comment threads, to the point of being a joke. Given the enthusiasm and locally concentrated levels of participation in this activity we see, it intuitively seems the case that journalists and broadcast meteorologists may have found themselves conditioned to avoid talking about climate, being sure of facing a dismal stream of abuse whenever they raised their head above the parapet. It's encouraging to read evidence suggestive of this fringe activity being pushed ever farther to the edges of the Bell curve of likely hobbies to pursue. Perhaps we may one day be able to move on, secure in the knowledge that needful public policy isn't accidentally being shaped by understimulated and underinformed idlers seeking kicks.
