Should scientists be bolder in public?

Is it the role of science to be brave and pick a side, or just to ask the searching questions?

I spoke at the London Climate Forum this weekend. This is a rough sketch of what I said.

Jeremy Grantham is the investor behind the “Grantham Institute” centres for climate change research at Imperial and the LSE. He recently wrote a provocative opinion piece for Nature, arguing:

Overstatement may generally be dangerous in science (it certainly is for careers) but for climate change, uniquely, understatement is even riskier and therefore, arguably, unethical. It is crucial that scientists take more career risks and sound a more realistic, more desperate, note on the global-warming problem. Younger scientists are obsessed by thoughts of tenure, so it is probably up to older, senior and retired scientists to do the heavy lifting. Be arrested if necessary. This is not only the crisis of your lives — it is also the crisis of our species’ existence. I implore you to be brave.

It’s a bold statement. But possibly not a fair one. As Roger Pielke Jr quipped, “how about you go first?“ More to the point, perhaps, many scientists recoiled from the suggestion, not simply because they lacked the courage or conviction of their work, but because they felt that isn’t a productive way to do science in public. People’s ideas of science vary, but to many it is not about boldly delivering anything, but asking questions.

And yet, perhaps Grantham has a point that climate is different. It’s more urgent, and there are more than enough people external to science ready to pounce and amplify your understatement for you. It’s surrounded by a very different political narrative of certainty and doubt than, for example, BSE. It’d be wrong to build a policy of scientific advice for climate based on models constructed in another crisis. Further, one might argue that climate science as a community is a bit too reticent, a bit too quick to hide (at least compared to other actors in the field), perhaps because the scientists who are currently at the most senior levels came into it before it was such a high profile political issue; they didn’t sign up for this.

In many ways, this isn’t a new dilemma. One might even say it’s the basic paucity of scepticism, the evental emptiness of doubt: At some point, you have to believe in something and act, or you do nothing. That doesn’t mean we have to be stuck though, it’s just a matter of deciding when you do choose to put questions to one side and act.

I don’t think we should be prescriptive about what scientists do here. If some would rather focus on uncertainty, fine, but equally I don’t think we should necessarily admonish those who take their work more boldly to the streets either (for one thing, that plays into stories those working against scientific advice would seek to promote: who are we really serving when we do such scolding?). That’s not to say we can’t critique individual actions we disagree with, but I’d like to think science is big and diverse enough to cover a range of approaches to science in society, and that we should be ok with that. If anything, we should celebrate and foster diversity of political attitude and approach. There’s a lot more to scientists in society than simply those who speak out and those who don’t; there are different ways to speak, a range of frames and a diversity of possible audiences. As Pielke Jr argues in his book The Honest Broker, their are various models for scientific advice one might choose, the important thing is scientists do pick one approach, and do so consciously  thinking about which they apply, when and why.

I’m not sure I agree with Grantham’s focus on senior scientists, although they will have to be more accepting of such an approach if younger, less senior ones are to be involved too. This kind of work doesn’t just have to be done scientists either, but other members of the scientific community: educators, public engagement officers, artists, psychologists, sociologists, writers, press officers, storytellers, filmmakers, all sorts. (Yes, these people are part of the scientific community – broadly defined – and many are very skilled too).

We just don’t see enough of this activity applied to climate science. And so, I’d say if Grantham really wants a stronger public discourse on climate science, he should put his money where his mouth is and fund some. There used to be the Grantham Prize for journalism, the funding for which was recently shifted to training journalists, but journalism is only one part of the sort of work needed here. I would like to see a much larger project of investment in a larger range of climate communications. (I think it should be funded by the government, but that’s another fight). I know way too many science communication people who deliberately frame their ideas to have a biomedical theme so they can apply to Wellcome public engagment grants. If Grantham helped put together a climate version, I’m sure many would shift their energies, and that’d probably be a lot more productive in the long run than front page photos of Brian Hoskins occupying an oil rig.

How Devon's humpback whale is dredging up the politics of the sea

The arrival of a humpback whale at Slapton Sands has caused a local splash. But the history of the village has a warning for those who think of the sea as spectacle alone.

The Devon coast road from Dartmouth to Torcross is as pretty as it is treacherous. After winding through a cliff-top village, the road ahead falls away to reveal a giant lake – the Slapton Ley - flanked by green hills on one side and ocean on the other. 

Tourists (or "grockles") gasp at the view and, in recent weeks, even locals have been staring out to sea - where a giant humpback whale has taken up residence in the bay.

Not seen at Slapton in living memory, the whale has swum into rural stardom. Hundreds have lined the beach with cameras and telescopes. The nearby pub and farm shop have seen levels of trade only usually enjoyed in the summer.

According to Keith Pugh, (the ice-cream-van-man who has been keeping the crowds supplied with tea) one lady from Plymouth caught the bus here every day for six weeks just to catch a single glimpse. That’s a four-hour round trip.

If this all sounds a bit fishy, that's because it is. Experts believe that the whale is feeding on the bumper numbers of small fish and mackerel that have been reported in the area. But even these are behaving in unexpected ways. “The mackerel are further north than usual for this time of year,” says Mark Darlaston, a photographer who first identified the whale as a humpback (and jokingly named it after storm “Doris”).

So what is the humpback up to, so far south of its northern feeding grounds? And should its presence be seen as a sign of recovery - for whales and UK waters in general? 

Not yet, say conservationists. And not if the history of Slapton is anything to go by.

Troubled waters

Villagers at Torcross, at the far end of Slapton sands, are familiar with secrets from the deep. In 1944, a military training in the bay went horribly wrong, when nearly 1,000 American servicemen were drowned. The tragedy was hushed up for decades.

But the greatest threat to the community comes from mismanagement of the sea itself. On 26 January 1917 the entire neighbouring village of Hallsands was swallowed by a storm. The tragedy was partially manmade. The underwater sandbanks, which had helped protect the shore from longshore drift, had been thoughtlessly dredged to supply building materials for the Plymouth docks. Some 660,000 tonnes of material were removed and never replaced.

The results of that plunder are still felt at Slapton today. In 2014, a gale-force storm swept away part of the road that runs between the sea and the ley. Just last year, the seawall at Torcross crumbled, as the protective beach beneath was carried away by waves.

Into the Brexit deeps

So much in our oceans is tightly connected to human activity. If whales are a rare sight on the UK coast, it is partly because of the human campaign against them for many years in the form of whaling. According to Sally Hamilton from the conservation charity Orca, the 1980s moratorium on whaling has helped some populations to recover. 

But others are still fighting to survive in the face of pollution, noise, and over-fishing. The UK’s last resident pod of killer whales looks likely to die out after high levels of PCB chemicals have stopped the females reproducing. In Norway, a stranded whale was found to have over 30 plastic bags blocking its digestive system.

There is also no certainty that the glut of fish that the whale is feeding on will come again next year. “There is still masses we don’t understand about the ocean,” says Will McCallum from Greenpeace, “Climate change and the threat of over-fishing mean that where fish are moving to is more unpredictable that it has ever been.”

And it's not just whales that could get caught out. Some UK politicians have demanded that a Brexit deal include blocking foreign vessels from fishing in British waters. With 58 per cent of UK-caught fish caught by non-British fleets, it is argued that a ban would benefit the UK industry.

Yet with migration patterns becoming more erratic, McCallum is sceptical. "Re-territorialising our waters would be an absolute potential disaster because we just don’t know where fish stocks are going to move," he says. 

Out of the Blues

At Torcross, the sea has long been a source of worry. Claire, the landlady at the Start Bay Inn, recalls the many storms that have pelted the seafront pub since she was a child. Just last year she was “running from one end to the other” trying to sweep the water out, while bottles rattled and the chip-fryer shook.

So it was perhaps unsurprising that news of the whale’s arrival first met with local concern. “I can’t bear to see it,” one woman tells me. She had read in the press that it had come so close in to shore to “beach” itself and die, and heard rumours it was in mourning for a lost calf.

But thanks to the investigations of Mark Darlaston and the divers at the British Divers Marine Life Rescue, such fake whale-news has been corrected - and its visits are fast becoming a source of wider hope. The owner of the Stokely farmshop has joked about replacing it with a decoy “nessie” when it leaves. Claire cannot wait to put its picture on the front of her menus (where the picture is currently of the recent storm).

It is not yet known what lies ahead for Brexit fishing policy, or for whales. But dip into the history of the village of Torcross, and it's clear that understanding and protecting the sea is inseparable from protecting ourselves.
