"We have 30,000 days!" "100 months!" "5 years left!" "Copenhagen (now Mexico) is our last chance!" In the face of consensus on the reality of climate change scientists, policy makers and campaigners are increasingly in the habit of issuing deadlines, ultimatums and points of no return.

But what impact does this language have on the decisions taken by activists, campaigners, and policymakers?

A provocative new film, Beyond the Tipping Point?, produced and directed by Dr. Stefan Skrimshire from The University of Manchester launched on a fortnight ago at the Manchester Museum.

Now it's publishers have made it freely available as an educational tool for campaign and community groups, schools and universities, to encourage people to discuss and reflect on the actions and decisions they take in relation to climate change.

The film features interviews with a Met Office international climate expert, a Bangladeshi social justice campaigner; members from direct action group Plane Stupid, Buddhist leaders and leading academics, alongside footage from the UN climate talks in Copenhagen.

A rich diversity of perspectives emerge from these interviews. Whilst some of the contributors argue that ‘shock and awe’ will force the public to take action, others say activists must be more careful in the way they communicate. One interviewee argues that we should focus our attention on adapting our neighbourhoods to combat the unavoidable effects of rising temperatures.

Our own Leo Murray, the creator of Wake up, Freak out, said, "This film offers insight into the implications of an imminent point of no return in the climate system, and should be seen by everyone involved in the struggle to prevent us from reaching that point. This type of critical reflection will be invaluable to our understanding of our own actions and what we seek to achieve by them."

We all know that the real cost of cheap flights is paid for by the planet. Aviation fuel is not taxed, and so flying gets a free ride. This means more people fly, increasing demand for high-emission transport and undermining low-carbon alternatives. The combination of cheap flights and gung-ho advertising campaigns creates a mindset that we need to be constantly travelling, which leads, inevitably, to catastrophic climate change and the end of the world.

We're seeing the impact of our oil addiction every day as the Gulf of Mexico disappears under brown gunge. Oil is costing us, and the planet, dearly. It's not about taxing it - we need to get off it all together! Trains and buses can be electric, which can be renewable. Planes can't, hence the need to reduce demand for flying.

Problem is, oil companies rule the roost, making sure that we don't get the change we need to save the future. But BP's scandalous cost-cutting, which led to this latest disaster, means that all that could be changing. The tide is turning against Big Oil, and now is the time to rise up agains the oil giants! Time to gatecrash their party.

The World National Oil Companies Congress at Grange St Pauls Hotel in London 21st – 24th June invites you to: “debate and decide the future of the oil business . . . Don’t forget to pack your tuxedos and gowns. Fine wine, exquisite food and the company of some of the greatest minds in the energy business guarantee you fun and networking at the highest level.”

Delegates will be arriving on Monday evening, 21 June at the Hotel at 10 Goodliman Street EC4. They "kick off with welcome drinks on a spectacular roof terrace overlooking St. Pauls Cathedral." Plane Stupid is joining the Camp for Climate Action and the UK Tar Sands Network to ruin their evening.

Gather at 6 pm at BP-sponsored Tate Modern, near the bridge across the Thames. Bring your own percussion, banners, slogans and energy.

Join the People’s Court at 7 pm outside the conference venue, where, in co-ordination with ADIEYIEMANFO Movement of Positive Action Networks who are fighting oil exploitation in Ghana, we will put the oil executives on trial for:

• wholesale wanton destruction by pollution, leaks, and flaring, of land and sea, fish and fowl, human lives and livelihoods, present and future;
• waging wars for oil;
• changing the climate to create an uninhabitable planet; And, as oil runs out,
• pursuing ever more costly and dangerous deposits from the depths of the ocean or from tar sands, instead of developing clean, sustainable forms of energy.

The Ghanese organisers for this event say:

"Oil drilling is being violently forced upon us in West Afrika with huge blood spilling. Our only defence is grassroots community self-empowerment . ... Let us therefore all rise up to the solidarity beat of our unifying peoples’ power across borders and drum out the plundering criminals! ... Neocolonialist and imperialist States and vampire capitalist transnational corporations must never be trusted with control over dangerous fossil fuels such as Oil."

Bring your own experience, and give and hear testimonies from the oil workers and communities who have for decades resisted the curse of black gold in the Tar Sands region of Canada, in the Niger Delta, in Ghana, Iraq, Colombia, Venezuela . . . and from people at the sharp end of the changing climate.

In a ceremony pre-empting Tuesday’s gala dinner and awards ceremony, companies will fight it out for the prestigious Dead Fish Award. BP? Shell? Chevron? Who will walk away with the prize?

Come help reward your favourite oil giant. Meeting at Tate Modern, 6pm, then off to Grange St Pauls Hotel, Goodliman St, London EC4
