Information Transient by Kip Hansen — 10 January 2023
Yet one more lesson in tips on how to write a good-news story as a Local weather Disaster story. One has at hand it to the Local weather Crazies – specific in journalism. In my favourite once-a-world-class newspaper, the New York Occasions, this story.
“By Henry Fountain and Mira Rojanasakul
The world remained firmly in warming’s grip final yr, with excessive summer time temperatures in Europe, China and elsewhere contributing to 2022 being the fifth-hottest yr on report, European local weather researchers stated on Tuesday.
The eight warmest years on report have now occurred since 2014, the scientists, from the European Union’s Copernicus Local weather Change Service, reported, and 2016 stays the most well liked yr ever.”
That is all the story in three pictures:
The left-hand picture appeared within the New York Occasions article. The appropriate-hand picture is from NOAA’s Local weather at a Look International Time Sequence web page. Clicking the hyperlink will carry up the charted picture (NB: I’ve diminished the horizontal measurement to match the Occasions’ picture).
Evaluate the 2 pictures, and apart from some minor variations within the 2015, 2016 and 2017 numeric values, they’re fairly comparable.
However (all the time a however), the NOAA graph can present, within the higher right-hand nook, a pattern line for 2015-2022, the “least 8 years” being highlighted within the NY Occasions piece.
Right here is the blow-up of that nook, with textual content re-typed for readability).
Including this pattern line is an choice on the unique official NOAA web page – see for your self. (repeating the hyperlink in your comfort).
The New York Occasions’ authors, Henry Fountain and Mira Rojanasakul, merely don’t point out the optimistic story that the final eight years have a pattern of minus 0.87°C/century.
So, the excellent news story that might have been written based mostly on the identical information – the identical information – is that NOAA’s calculated International Land and Ocean January-December Temperature Anomalies have been sharply down-trending since 2015.
And that’s the temporary.

Writer’s Remark:
My long-term recommendation is “Don’t draw pattern strains on graphs.” The slope of a pattern line all the time relies on beginning and ending factors. It’s [almost] all the time extra informative to have a look at the information itself, in lots of differing graphic types than to attract strains on high of the information. The pattern line shouldn’t be the information – it’s an “opinion” of whoever is drawing the pattern (or the programmer of the graphing software program) regarding begin and finish dates.
That is true even of knowledge that appears to have an apparent begin date or a temporally very lengthy information set similar to fashionable international thermometer temperature units. International temperature didn’t start the second it began being measured.
It needs to be famous that two El Niños happen within the interval in query: 2014–16 and 2018–19.
Journalism, by its personal requirements, is supposed to present a dis-interested, well-rounded, balanced view of the subject of a information story. The eight-year downtrend actually warranted no less than a point out on this story of the final eight years of “international” temperatures.
