If you're under 45, you'll see climate change's effects in person

We're still caught up in a 1980s mindset.

BusinessGreen's James Murray writes about "Clinging to a climate of optimism" when it comes to fighting climate change:

My point is this: if you are over 45, then you are on track to bequeath the rest of us a pretty scary inheritance. But if you are under 45, then you have a good chance of experiencing some of the more devastating results of our failure to leave fossil fuels in the ground for yourself. You will see first-hand whether we are capable of building a genuinely sustainable global economy by mid-century or not. You will find out if it is possible to support nine billion people in a warmer world. You have a direct stake in this game.

In a way, it comes back to the argument I made last week about the risks of imprecision: climate change has been mentally filed away in the "legacy to our grandchildren" box for the last forty years. But while it's painfully obvious that something happening "in 2080" is getting closer every year, it's not quite so easy to continually readjust your perceptions for something which you've estimated as "a long way in the future".

And so we end up in the trap Murray addresses, where even people who were born after climate change first hit the agenda have it wrongly pegged as something they won't be alive to see. There's a level of urgency which people understand on an intellectual level, but not on a practical one. That is, someone perfectly happy to talk about "two degrees warming by 2050" still blanches when discussing the Thames Barrier being breached in their lifetime.

What effects could that practical understanding have on our approach to the issue? Murray writes:

Too many environmental debates are akin to arguing in 1940 about whether the allies should build tanks or planes.

We are past the point where we have the luxury of working out what the "best" sort of investment is to fight climate change – and really, we should never have been having that argument in the first place. A carbon-free energy infrastructure would always have a mix of inputs, from wind and solar to nuclear and CCS-equipped gas generation, and while some mixes might work better than others, all of them are better than the status quo.

But you don't even need to decide which energy mix you want, because with an appropriate policy background you could leave providers to make their own choices. That could be a cap-and-trade system which actually caps, as opposed to just trading, or it could be a carbon tax levied at a high enough level to make a difference, but whatever it is, it needs to be passed sooner rather than later.

Why are boundary changes bad for Labour?

New boundaries, a smaller House of Commons and the shift to individual electoral registration all tilt the electoral battlefield further towards the Conservatives. Why?

The government has confirmed it will push ahead with plans to reduce the House of Commons to 600 seats from 650.  Why is that such bad news for the Labour Party? 

The damage is twofold. The switch to individual electoral registration will hurt Labour more than its rivals. . Constituency boundaries in Britain are drawn on registered electors, not by population - the average seat has around 70,000 voters but a population of 90,000, although there are significant variations within that. On the whole, at present, Labour MPs tend to have seats with fewer voters than their Conservative counterparts. These changes were halted by the Liberal Democrats in the coalition years but are now back on course.

The new, 600-member constituencies will all but eliminate those variations on mainland Britain, although the Isle of Wight, and the Scottish island constituencies will remain special cases. The net effect will be to reduce the number of Labour seats - and to make the remaining seats more marginal. (Of the 50 seats that would have been eradicated had the 2013 review taken place, 35 were held by Labour, including deputy leader Tom Watson's seat of West Bromwich East.)

Why will Labour seats become more marginal? For the most part, as seats expand, they will take on increasing numbers of suburban and rural voters, who tend to vote Conservative. The city of Leicester is a good example: currently the city sends three Labour MPs to Westminster, each with large majorities. Under boundary changes, all three could become more marginal as they take on more wards from the surrounding county. Liz Kendall's Leicester West seat is likely to have a particularly large influx of Tory voters, turning the seat - a Labour stronghold since 1945 - into a marginal. 

The pattern is fairly consistent throughout the United Kingdom - Labour safe seats either vanishing or becoming marginal or even Tory seats. On Merseyside, three seats - Frank Field's Birkenhead, a Labour seat since 1950, and two marginal Labour held seats, Wirral South and Wirral West - will become two: a safe Labour seat, and a safe Conservative seat on the Wirral. Lillian Greenwood, the Shadow Transport Secretary, would see her Nottingham seat take more of the Nottinghamshire countryside, becoming a Conservative-held marginal. 

The traffic - at least in the 2013 review - was not entirely one-way. Jane Ellison, the Tory MP for Battersea, would find herself fighting a seat with a notional Labour majority of just under 3,000, as opposed to her current majority of close to 8,000. 

But the net effect of the boundary review and the shrinking of the size of the House of Commons would be to the advantage of the Conservatives. If the 2015 election had been held using the 2013 boundaries, the Tories would have a majority of 22 – and Labour would have just 216 seats against 232 now.

It may be, however, that Labour dodges a bullet – because while the boundary changes would have given the Conservatives a bigger majority, they would have significantly fewer MPs – down to 311 from 330, a loss of 19 members of Parliament. Although the whips are attempting to steady the nerves of backbenchers about the potential loss of their seats, that the number of Conservative MPs who face involuntary retirement due to boundary changes is bigger than the party’s parliamentary majority may force a U-Turn.

That said, Labour’s relatively weak electoral showing may calm jittery Tory MPs. Two months into Ed Miliband’s leadership, Labour averaged 39 per cent in the polls. They got 31 per cent of the vote in 2015. Two months into Tony Blair’s leadership, Labour were on 53 per cent of the vote. They got 43 per cent of the vote. A month and a half into Jeremy Corbyn’s leadership, Labour is on 31 per cent of the vote.  A Blair-style drop of ten points would see the Tories net 388 seats under the new boundaries, with Labour on 131. A smaller Miliband-style drop would give the Conservatives 364, and leave Labour with 153 MPs.  

On Labour’s current trajectory, Tory MPs who lose out due to boundary changes may feel comfortable in their chances of picking up a seat elsewhere.
