How two farm-boys-done-good could change the world

While everyone loves Commander Chris Hadfield, it's Iowan James Hansen who really needs the attention.

One was a farm boy from Ontario, the other the son of itinerant Iowa farmers. Both are now world-renowned scientists and activists with the attention of global leaders. However, the public only listens to one of them. The wrong one.

Commander Chris Hadfield has expanded our horizons, making the International Space Station an accessible place to virtually visit, and giving us wonderful views of our planet photographed from space. When the Canadian astronaut recorded a version of David Bowie's Space Oddity for his departure from the ISS, it was played on national news broadcasts across the globe and has been viewed more than 12 million times on YouTube.

It's a stark contrast with the stern-faced Iowan caution of James Hansen. The world's most renowned climate scientist has little joy to bring. Instead of heart-warming photos of electric lights blazing from the surface of Earth, he has dull graphs showing the slow, steady advance of the global warming apocalypse – ironically, caused in part by the electric lights that have made Hadfield's pictures so popular. Hansen doesn't have a song.

He doesn't even have a particularly motivating speaking style. You'd be forgiven for thinking that Hansen was a firebrand. He gets arrested in protests over environment-damaging mining practices and the construction of a pipeline that will bring the world's dirtiest oil to market. NASA has tried to gag him – and he gathered evidence of this and then took it to the New York Times. He has lobbied national leaders the world over. But Hansen is a fact-driven, cautious speaker who is careful not to get emotional over his message.

That is probably why it hasn't made any headway. If you heard the sound of weeping and gnashing of teeth in central London last night [16 May], it was because Hansen was giving a talk. The howling from the LSE lecture hall wasn't outrage over climate change - everyone in the building already appreciated those facts. What became increasingly clear as Hansen spoke was that there is no way to make anyone in power do anything about them.

Being informed is not enough. In April, Hansen retired from his position as director of NASA's Institute of Space Studies in order to be able to sue the federal government (government employees are not allowed to sue their employer) over their lack of action on climate change. The federal government's defence is likely to be, "well, it was all so dull, James."

By Hansen's own admission, the whole subject is "too technical for the public". He has tried to soften the message by framing the issue in terms of the world that we are bequeathing to his descendants. In his book Storms of my Grandchildren, Hansen allowed himself "one graph per chapter" he said last night. It was still too much: the book was dismissed as dry. He is currently forcing his message downwards in complexity by working on another book that is composed of a series of letters to his first grandchild, called Sophie's Planet. He's not confident it will make any difference at all. An audience member asked how he would reach the people who mattered: the ones who didn't fancy coming to hear him speak. "I don't really have a good answer to that," he said.

It would be interesting to know what Hadfield's answer would be - if he were allowed to speak. Hansen was in Europe to give testimony to the European Parliament about the folly of using oil from the Canadian tar sands. This is not something a Canadian scientist can do: if they receive government money, they are not allowed to talk about environmental issues without government permission, which is rarely forthcoming. Coverage of government-funded climate change research has dropped by 80 per cent in Canadian media because reporters can't access the researchers.

By now, however, Hadfield surely has the global currency to take off the gag without fear of reprisals from the Harper government. Perhaps he could even write the protest song that Hansen so desperately needs. At the end of the 1960s, the Apollo astronauts' experience and photography of Earth from space kick-started the modern environmental movement: their photographs made us fall in love with Earth. Hadfield has successfully repeated the trick for the age of social media – now he should use his power for good. If he were to join forces with Hansen, it's conceivable that two farm boys might just save the world.

No, the Brexit vote wasn't just about immigration

The data shows that most voters want a fairer society. Labour must fight for this in the Brexit negotiations. 

The result of the UK referendum to leave the European Union has shaken the political establishment to its core. As I have argued since then, it should be a wakeup call to all political parties.

Some have also argued that the referendum result is having international repercussions, with the election of Donald Trump to the White House cited as "Brexit Plus Plus". With the imminent election in France, and Germany’s later this year, responsible analysts are trying to understand why people voted the way they did and what this means. Too often, there are knee jerk explanations without any evidentiary justification to back them up. 

Analysis of who voted to leave shows the majority of people who voted to leave live in the South of England, and 59 per cent were from the middle classes (A, B, C1). Only 21 per cent of people in the lowest income groups voted to leave.

Analysis of why people voted as they did is more complex. This includes an increase in Euroscepticism particularly from older, middle class voters; concerns about globalisation and the impact on jobs; inequalities and being left behind; and new voters who didn’t vote in the 2015 General Election, for whom immigration was a concern. When this analysis is overlaid on analysis of that election, some themes emerge. The attitudes and values of the majority of the British public are firmly rooted in the desire for a fairer society, based on principles of equality and social justice. Although immigration played a part in the election and referendum results, perceived competence, being "left behind" and disillusionment with the direction of change were the key drivers.

Whether people voted to remain or leave, they did so because they believed that they and their families would be better off, and the majority who voted believed they would be better off if we leave the EU. Labour accepts and respects this. We have said that we will vote for Article 50, but we intend to hold this Tory government to account to ensure we get the best possible deal for the country.

In his speech last week, Jeremy Corbyn set out the issues that Labour will hold the government to account on. We have been absolutely clear that we want tariff-free access to the single market, to ensure that Britain continues to trade openly with our European neighbours, and to protect the cost of living for families struggling to get by. Getting the best deal for the UK means that we must continue to have a strong relationship with our EU neighbours.

Under my work and pensions portfolio, for example, we know that 40 per cent of pension funds are invested outside of the UK. If we want to guarantee a dignified and secure retirement for our pensioners, we must ensure that savers can get the best returns for the investments they make.

We also know that many of the protections that have until now been offered by the European Union must continue to be guaranteed when we leave. Provisions that secure the rights of disabled people, or that protect worker’s rights are an essential part of British society, enhanced by the EU. These cannot be torn up by the Tories.

Defending these rights is also at the heart of our approach to immigration. The dire anti-migrant rhetoric from some parts of the media and certain politicians, is reprehensible. I reject this scapegoating, which has fear and blame at its heart, because it is not true. Blaming migrants for nearly seven wasted years of Tory austerity when they are net contributors of over £2bn a year to the economy is perverse.

Of course we need to respond when public services are coming under pressure from local population increases. That’s why Labour wants to reinstate the Migration Impact Fund that the Tories abolished. We also need to ensure new members of communities get to know their new neighbours and what’s expected of them.

We believe that migrants’ broader contribution to British society has too often been obscured by the actions of unscrupulous employers, who have exploited new arrivals at the expense of local labour. A vast network of recruitment and employment agencies has developed in this country. It is worth hundreds of billions of pounds. Last year over 1.3m people were employed in the UK by these agencies. In 2007, 1 in 7 of these people came from the EU. We should ask how many are recruited directly from the EU now, and offered precarious work on very low wages whilst undercutting local labour. Labour will put an end to this practice, in order to protect both those who come here to work and those that grew up here.

Importantly, however, we cannot let our exit from the EU leave us with skill shortages in our economy. Our current workforce planning is woeful, particularly for the long-term. We need to reduce our need for migrant labour by ensuring our young, and our not so young, are trained for the jobs of the future, from carers to coders. Again, the Conservatives have undermined people’s chances of getting on by cutting college funding and the adult skills budget.

Unlike the government, Labour will not shirk from our responsibilities to the nation. Our plans for Brexit will respect the referendum result, whilst holding the Government to account and delivering a better future for all our people, not just the privileged few.
