A carbon tax may not actually do a whole lot for emissions

There's a chicken/egg problem at work.

A carbon tax is most economists' favourite method of dealing with climate change. It is exactly the sort of simple, market-driven intervention that they tend to like: set a price per tonne of carbon emitted which is equal to the value of the damage that tonne does to the climate, and then sit back and what businesses and consumers react. Some may cut their usage; some may switch to low-carbon sources of energy, which suddenly become cheaper comparatively; and some may choose to just pay the extra cost (what happens in that last situation is debatable – some think the money should just count as general taxation, others that it should be put towards climate change prevention and mitigation).

The Washington Post's Brad Plumer suggests that it may not work as well as we would hope, however. He reports on a recent MIT study looking at the likely effect of a $20 a ton carbon tax in the real world – the value proposed by a pair of MIT researchers last month.

Plumer writes:

Sebastian Rausch and John M. Reilly of the MIT Global Change Institute recently put forward a proposal for a $20/ton carbon tax that would rise 4 percent each year, starting in 2013. (The funds would be used to offset taxes elsewhere.) Here’s what their economic model predicts would happen to U.S. greenhouse-gas emissions:

Blue line: MIT reference case with no carbon tax. Black line: EIA reference. Green line: Scenario with MIT carbon tax in place.

With a carbon tax in place, U.S. greenhouse gas emissions do start declining quite a bit (this is the green line). But by 2030, emission levels stall, even though the carbon tax keeps rising and rising each year. The United States wouldn’t get anywhere near the 80 percent cut by 2050 that the White House has envisioned.

One explanation here is that MIT’s proposed carbon tax just isn’t high enough. But Muro favors another possibility–that a carbon tax alone isn’t enough to drive deep reductions. The private sector tends to under-invest in energy R&D and key bits of infrastructure such as transmission lines. Without further policies, it’s unlikely that we’ll see a sweeping transformation of our energy system to give people alternatives to coal plants and gasoline-powered cars.

This echoes an argument I've heard several times from those on the more technical side of climate change prevention. For all that the economists and politicians like to talk about creating the conditions in which the private sector will be incentivised to help tackle climate change, those who are more keenly aware of the massive costs involved tend to be rather more pessimistic.

They point out that the carbon tax model provides a cash injection to providers of low-carbon energy – but only after the tax is already instituted. As a result, there's another weak link in the chain, which is the ability of those providers to secure loans to build the capacity required. That's possible for massive companies looking to get into a new area; and it's possible for smaller companies, provided they get enough certainty from the government to be able to convince bankers.

But the fear is that larger companies, already strongly embedded in the conventional energy infrastructure, have little incentive to devote money, which could be used to lower the cost of polluting fuels, to instead build new capacity; and smaller companies won't be left with enough time between when the government finally confirms a carbon tax, and when their new generation is actually needed.

At the same time, though, there is growing evidence that some companies really are going above and beyond the call of duty. Some of it may be greenwashing, and some may be token expenditure, but if there really is any sizeable investment in low-carbon infrastructure, then it makes a carbon tax that much more effective.

Carbon taxes can only lower emissions if they raise the price of polluting relative to an alternative. If that alternative isn't available, then they risk being simply another source of revenue for the state.

Why is it called Storm Doris? The psychological impact of naming a storm

“Homes being destroyed and lives being lost shouldn’t be named after any person.”

“Oh, piss off Doris,” cried the nation in unison this morning. No, it wasn't that everyone's local cantankerous old lady had thwacked our ankles with her stick. This is a different, more aggressive Doris. Less Werther’s, more extreme weathers. Less bridge club, more bridge collapse.

This is Storm Doris.

A storm that has brought snow, rain, and furious winds up to 94mph to parts of the UK. There are severe weather warnings of wind, snow and ice across the entire country.

But the real question here is: why is it called that? And what impact does the new Met Office policy of naming storms have on us?

Why do we name storms?

Storm Doris is the latest protagonist in the Met Office’s decision to name storms, a pilot scheme introduced in winter 2015/16 now in its second year.

The scheme was introduced to draw attention to severe weather conditions in Britain, and raise awareness of how to prepare for them.

How do we name storms?

The Name our Storms initiative invites the public to suggest names for storms. You can do this by tweeting the @metoffice using the #nameourstorms hashtag and your suggestion, through its Facebook page, or by emailing them.

These names are collated along with suggestions from Met Éireann and compiled into a list. These are whittled down into 21 names, according to which were most suggested – in alphabetical order and alternating between male and female names. This is done according to the US National Hurricane Naming convention, which excludes the letters Q, U, X, Y and Z because there are thought to be too few common names beginning with these letters.

They have to be human names, which is why suggestions in this list revealed by Wired – including Apocalypse, Gnasher, Megatron, In A Teacup (or Ena Tee Cup) – were rejected. The Met Office received 10,000 submissions for the 2016/17 season. According to a spokesperson, a lot of people submit their own names.

Only storms that could have a “medium” or “high” wind impact in the UK and Ireland are named. If there are more than 21 storms in a year, then the naming system starts from Alpha and goes through the Greek alphabet.

The names for this year are: Angus (19-20 Nov ’16), Barbara (23-24 Dec 2016), Conor (25-26 Dec 2016), Doris (now), Ewan, Fleur, Gabriel, Holly, Ivor, Jacqui, Kamil, Louise, Malcolm, Natalie, Oisín, Penelope, Robert, Susan, Thomas, Valerie and Wilbert.

Why does this violent storm have the name of an elderly lady?

Doris is an incongruous name for this storm, so why was it chosen? A Met Office spokesperson says they were just at that stage in their list of names, and there’s no link between the nature of the storm and its name.

But do people send cosy names for violent weather conditions on purpose? “There’s all sorts in there,” a spokesperson tells me. “People don’t try and use cosy names as such.”

What psychological impact does naming storms have on us?

We know that giving names to objects and animals immediately gives us a human connection with them. That’s why we name things we feel close to: a pet owner names their cat, a sailor names their boat, a bore names their car. We even name our virtual assistants –from Microsoft’s Clippy to Amazon’s Alexa.

This gives us a connection beyond practicality with the thing we’ve named.

Remember the response of Walter Palmer, the guy who killed Cecil the Lion? “If I had known this lion had a name and was important to the country or a study, obviously I wouldn’t have taken it,” he said. “Nobody in our hunting party knew before or after the name of this lion.”

So how does giving a storm a name change our attitude towards it?

Evidence suggests that we take it more seriously – or at least pay closer attention. A YouGov survey following the first seven named storms in the Met Office’s scheme shows that 55 per cent of the people polled took measures to prepare for wild weather after hearing that the oncoming storm had been named.

“There was an immediate acceptance of the storm names through all media,” said Gerald Fleming, Head of Forecasting at Met Éireann, the Irish metereological service. “The severe weather messages were more clearly communicated.”

But personalising a storm can backfire. A controversial US study in 2014 by PNAC (Proceedings of the National Academy of Sciences) claimed that hurricanes with female names lead to higher death tolls – the more “feminine” the name, like Belle or Cindy, the higher the death toll. This is not because female names are attached to more severe storms; it is reportedly because people take fewer steps to prepare for storms with names they perceive to be unintimidating or weak.

“In judging the intensity of a storm, people appear to be applying their beliefs about how men and women behave,” Sharon Shavitt, a co-author of the study, told the FT at the time. “This makes a female-named hurricane . . . seem gentler and less violent.”

Names have social connotations, and affect our subconscious. Naming a storm can raise awareness of it, but it can also affect our behaviour towards it.

What’s it like sharing a name with a deadly storm?

We should also spare a thought for the impact sharing a name with a notorious weather event can have on a person. Katrina Nicholson, a nurse who lives in Glasgow, says it was “horrible” when the 2005 hurricane – one of the fifth deadliest ever in the US – was given her name.

“It was horrible having something so destructive associated with my name. Homes being destroyed and lives being lost shouldn’t be named after any person,” she tells me over email. “I actually remember at the time meeting an American tourist on a boat trip in Skye and when he heard my name he immediately linked it to the storm – although he quickly felt guilty and then said it was a lovely name! I think to this day there will be many Americans who hate my name because of it.”
