Lesson learned: Qualities of successful

science communication

• Credibility

• Legitimacy

• Salience

• Good story telling

Challenge: Capturing reader attention

• Headline and lead in to any discussion needs to be strongest, most compelling – Newspaper readers read 56% of the headlines, but only 13% of

the stories are at least half-read. (Joe Romm, Language Intelligence)

• Stories w/ boring headlines become irrelevant; nuance doesn’t sell and not enough characters for it

• Perceived click bait, sensationalism can backfire

• Objective: Find the right balance

Some lessons learned: Effective weather communication

• Confidence levels in forecasts

• Scenarios for complex, high impact events

• Compelling visuals

• Specifics on timing, location

• Accountability

• Learn by doing, seek feedback

•High: Bank on it.

•Medium-High: Overall forecast is sound,

but minor variations are possible.

•Medium: We think we’re on the right track,

but the forecast details are still taking

shape.

•Low-Medium: This is our best guess, but

don’t hold us to it.

•Low: Crapshoot.

Confidence levels

Snow case

• Learning from a bad forecast: The

Snowquester, March 6, 2013

Snowquester (March 6, 2013):

The forecast we issued Reality

A bad forecast for a high impact storm can be devastating for consumer trust

“Never has there been an industry which spends so much time churning out so much bull”

“ I can tell you that weather predictions have always been a standing joke. It's all a scam to increase ratings on the weather shows, and to reward advertisers”

“As far as I am concerned, all of our local meteorologist should be fired for cause. Why? Because they are wrong more often than right and costs us big money.”

But readers also told us they’d welcome more honesty, uncertainty, probabilistic information

Brad Panovich, WCNC

The best forecast for

Snowquester was one we could

not issue with a straight face, and

one most Washingtonians would

have ridiculed: Rain, sleet, and/or

snow likely - heavy at times - with

snow accumulations of 0-14

inches.

“Yes. Why not? The rain/snow line will be

wobbling all over so that's all you can say.

If it's the best, it's the best. Say that, and

then give your probabilities. ”

“What does ridicule have to do with it? I

support the CWG, but this business about

how meteorologists have to depart from

truth and accuracy because they're

worried about their popularity ratings I

don't understand. Are they scientists or

entertainers?”

The winter after Snowquester

Sandy

A successful scenario approach

8 days out: a heads-up

5-7 days out

Provide general level sense of what could

happen

“Although a historic storm is a possibility, the

storm could deliver just a glancing blow or even

miss the East Coast entirely. And for residents

of the mid-Atlantic (including Washington, D.C.

and points further south), a direct hit is not

particularly likely although it cannot be ruled

out.

“Residents of the Northeast, perhaps, should

be most concerned. The European model -

which did the best job simulating hurricane

Isaac’s track in late August - delivers a

devastating blow from central New Jersey to

southern New England (including New York

City)”

b55c38388962_blog.html)

4 days out:

Communicate 4 scenarios SCENARIO 1 - NJ TO Long Island landfall: Indirect

hit, major impacts [for DC] (45 percent chance)

SCENARIO 2 - Mid-Atlantic landfall: Worst case –

direct hit, severe impacts (30 percent chance)

SCENARIO 3 – New England landfall: Glancing blow,

minor impacts (20 percent chance)

SCENARIO 4 – Out to sea: FEW IMPACTS (5 percent

chance)

3 days out

Communicate 3 scenarios SCENARIO 1 - Landfall from Virginia

Beach to the Delmarva: Worst case

(1 in 3 chance)

SCENARIO 2 – Landfall over south

Jersey: Almost direct hit (1 in 3

chance)

SCENARIO 3 - Landfall between

northern New Jersey and southern

New England: Indirect hit (1 in 3

chance)

2 days out

Communicate 2 scenarios SCENARIO 1- Landfall from northern

Delmarva to northern New Jersey: Near

direct hit (70 percent chance, very bad

case)

SCENARIO 2 - Landfall from southern to

central Delmarva: Direct hit (30 percent

chance, worst case)

Challenge: The armchair

meteorologist problem • Social media gives everyone a voice, irrespective of

credentials

• High school kids, weather amateurs, (pros too) can

misuse, misinterpret model and push out unreliable info

that spreads virally

What should digital and

broadcast meteorologists do? Confront? Ignore? Engage constructively w/

bad actors?

“pointless to expose and shame…It’s a never- ending

and unwinnable game of whack-a-mole. ”

“Focus on educating audience on limitations of weather

forecast” (http://www.washingtonpost.com/blogs/capital-weather-gang/wp/2014/08/20/hurricane-hype-is-here-to-stay-forecasters-must-adapt/)

National Hurricane Center speaks out…

“Now that we have entered the heart of the hurricane season, there is an

increase in the Internet hype around disturbances that NHC is monitoring.

Given the long lead times involved, the wide range of possible outcomes, and

the historically poor and erratic performance of guidance models with weak

disturbances, there is no reliable science to forecast potential impacts to

specific locations that would be more than a week away.

. . .

“…The bottom line really is: be alert, be prepared, but also be wary of long-

range projections that go beyond what the science can offer. And make

the NOAA National Hurricane Center www.hurricanes.gov your calm, clear, and

trusted source for official forecast and warning information on tropical

cyclones.”

Challenge: Some for-profit companies

providing unreliable forecasts

• Weather forecast “skill” is no more than 7-

10 days into the future

AMS: “Presently, forecasts of daily or

specific weather conditions do not exhibit

useful skill beyond eight days, meaning that

their accuracy is low.”

• Yet some companies provide such

forecasts 90 (or more) days out with no

uncertainty information

• Misleading? Ethical issues?

Lessons learned:

Climate change communication

• Don’t cherry pick and hype – discuss full range of results and credible views; nuance builds credibility

• Avoid labels “deniers”, “alarmists”, “warmists”…better “convinced”, “unconvinced” (doubters or skeptics ok, depending on context)

• Consider alternative views, but avoid “false balance” (equal time)

• Be respectful of different voices in the crowd. Don’t demonize people, perspectives.

Thank you!
