Climate change: the scientific debate is over. Political and policy action must start now

The IPCC report has given the government a wake-up call.

Today, one part of the climate change debate comes to an end. The scientific debate is over. The IPCC, a huge distinguished panel of international climate scientists, has concluded that to limit climate change, the world must make a continued and substantial reductions of greenhouse gas emissions. No other scientific conclusion has been subjected to such prolonged,detailed, global scrutiny. Those responsible for our media coverage – particularly the BBC – should take note.

Time should be called on a long, rancorous, and frequently very odd debate, in which a tiny number of individuals and small groups – frequently with clear vested interests - have been given equal weight to 97 per cent of climate scientists. The Flat Earth Society still exists, but that doesn’t mean we have to take them seriously.

Of course it’s not just climate scientists – and green campaigners - who’ve recognised the pressing urgency of action on climate change. From the head of the IMF, Christine Lagarde, who said climate change kept her awake at night, to 83 per cent of Global 500 companies which have recognised climate change as a serious risk to their operations, to the heavily at-risk inhabitants of fragile small island nations around the globe, there’s wide understanding. As Ban Ki-Moon, UN Secretary-General has said: “"The heat is on. Now we must act."

Those opposed to “green” action in Britain often say that we can’t afford it in today’s economic climate. On the contrary, we can’t afford not to act for the sake of both economy and environment. And that’s not just because of the risk of the floods, the droughts, the heatwaves, are already having huge human and financial costs, but because of the weaknesses and the failures of the very foundations of our economy and everyday life, structures built on massive consumption of once-cheap fossil fuels that we can no longer afford.

We have a huge problem with fuel poverty in Britain, the result in part of rising energy prices – almost all due to the rising cost of gas and distribution costs in our privatised system, but also of our leaky, poor insulated homes. With not a penny of government funds currently going into home insulation, we’re not only missing out on tackling that problem – but also creating tens of thousands of good, long-term jobs, as well as cutting carbon emissions.

We have a huge problem with unemployment, under-employment and low pay in Britain. Investing in and developing renewable energy generation technologies – based around our rich wind and tidal power sources – offers the chance to generate.

The Centre for Alternative Technology has calculated that together renewable technologies and energy conservation can deliver up to 1.5 million good new jobs.

We have a huge problem with food poverty in Britain – with half a million people dependent, today, on food banks to get enough to eat. We need to bring food production back to Britain, restoring the ring of market gardens around our towns and cities, ensuring food security in our increasingly uncertain world, removing currency risk. We must end the dreadfully wasteful, destructive practice of air freighting fruit and vegetables, and cutting down our practice of shipping them around the world.

We have a growing problem of “transport poverty” in Britain – fast rising rail and bus fares that are trapping our often forced commuters into further poverty. We need to develop a transport plan for England' built at its base around walking and cycling (worth noting that 1.3 million more new bicycles were bought last year in Britain than cars registered), with affordable, reliable, timely public transport available for longer journeys. Again, more good jobs, as well as cleaner air and better public health.

There are also looming threats that we need to avert. Green MP Caroline Lucas has highlighted the economic threat of the “carbon bubble” – the unburnable fossil fuels whose valuation underlies the stock prices of some of our largest companies. We need to think long and hard about how to manage that risk, how we can keep more than half of our known fossil fuel reserves in the ground, not subsidise the potential new and risky operation of fracking for shale gas, as our government is currently doing.

It’s not surprising that we’ve seen uncertainty about climate change growing in Britain, with a recent poll showing 19 per cent of people were not sure about the human cause of it. (Although of course 72 per cent were sure). With the government failing to take action, with a Lib Dem energy secretary saying he “loves” shale gas, some people understandably thought that perhaps climate change was something they didn’t have to worry about. But they, and the government, have today been given a wake-up call.

Britain has been a leader, and we can, and must, be again. In passing the 2008 Climate Change Act, Britain stood out in declaring its collective intention to reduce greenhouse gas emissions. Now we need to match that with action.

Let's seize our chance of a progressive alliance in Richmond - or we'll all be losers

Labour MPs have been brave to talk about standing aside. 

Earlier this week something quite remarkable happened. Three Labour MPs, from across the party’s political spectrum, came together to urge their party to consider not fielding a candidate in the Richmond Park by-election. In the face of a powerful central party machine, it was extremely brave of them to do what was, until very recently, almost unthinkable: suggest that people vote for a party that wasn’t their own.
Just after the piece from Lisa Nandy, Clive Lewis and Jonathan Reynolds was published, I headed down to the Richmond Park constituency to meet local Green members. It felt like a big moment – an opportunity to be part of something truly ground-breaking – and we had a healthy discussion about the options on the table. Rightly, the decision about whether to stand in elections is always down to local parties, and ultimately the sense from the local members present was that it would be difficult  not to field a candidate unless Labour did the same. Sadly, even as we spoke, the Labour party hierarchy was busily pouring cold water on the idea of working together to beat the Conservatives. The old politics dies hard - and it will not die unless and until all parties are prepared to balance local priorities with the bigger picture.
A pact of any kind would not simply be about some parties standing down or aside. It would be about us all, collectively, standing together and stepping forward in a united bid to be better than what is currently on offer. And it would be a chance to show that building trust now, not just banking it for the future, can cement a better deal for local residents. There could be reciprocal commitments for local elections, for example, creating further opportunities for progressive voices to come to the fore.
While we’ve been debating the merits of this progressive pact in public, the Conservatives and Ukip have, quietly, formed an alliance of their own around Zac Goldsmith. In this regressive alliance, the right is rallying around a candidate who voted to pull Britain out of Europe against the wishes of his constituency, a man who shocked many by running a divisive and nasty campaign to be mayor of London. There’s a sad irony in the fact it’s the voices of division that are proving so effective at advancing their shared goals, while proponents of co-operation cannot get off the starting line.
Leadership is as much about listening as anything else. What I heard on Wednesday was a local party that is passionate about talking to people and sharing what the Greens have to offer. They are proud members of our party for a reason – because they know we stand for something unique, and they have high hopes of winning local elections in the area.  No doubt the leaders of the other progressive parties are hearing the same.
Forming a progressive alliance would be the start of something big. At the core of any such agreement must be a commitment to electoral reform - and breaking open politics for good. No longer could parties choose to listen only to a handful of swing voters in key constituencies, to the exclusion of everyone else. Not many people enjoy talking about the voting system – for most, it’s boring – but as people increasingly clamour for more power in their hands, this could really have been a moment to seize.
Time is running out to select a genuine "unity" candidate through an open primary process. I admit that the most likely alternative - uniting behind a Liberal Democrat candidate in Richmond Park - doesn’t sit easily with me, especially after their role in the vindictive Coalition government.  But politics is about making difficult choices at the right moment, and this is one I wanted to actively explore, because the situation we’re in is just so dire. There is a difference between the Conservatives and the Lib Dems. Failing to realise that plays into the hands of Theresa May more than anyone else.
And, to be frank, I'm deeply worried. Just look at one very specific, very local issue and you’ll perhaps understand where I'm coming from. It’s the state of the NHS in Brighton and Hove – it’s a system that’s been so cut up by marketisation and so woefully underfunded that it’s at breaking point. Our hospital is in special measures, six GP surgeries have shut down and private firms have been operating ambulances without a license. Just imagine what that health service will look like in ten years, with a Conservative party still in charge after beating a divided left at another general election.
And then there is Brexit. We’re hurtling down a very dangerous road – which could see us out of the EU, with closed borders and an economy in tatters. It’s my belief that a vote for a non-Brexiteer in Richmond Park would be a hammer blow to Conservatives at a time when they’re trying to remould the country in their own image after a narrow win for the Leave side in the referendum.
The Green party will fight a passionate and organised campaign in Richmond Park – I was blown away by the commitment of members, and I know they’ll be hitting the ground running this weekend. On the ballot on 1 December there will only be one party saying no to new runways, rejecting nuclear weapons and nuclear power and proposing a radical overhaul of our politics and democracy. I’ll go to the constituency to campaign because we are a fundamentally unique party – saying things that others refuse to say – but I won’t pretend that I don’t wish we could have done things differently.

I believe that moments like this don’t come along very often – but they require the will of all parties involved to realise their potential. Ultimately, until other leaders of progressive parties face the electoral facts, we are all losers, no matter who wins in Richmond Park.
