Well, we never said it would be easy.
The Paris Agreement had been signed the day before. The newspapers were reporting the planet had been saved.
The action was to highlight the five Red Lines that we would not compromise on in the defence of the climate.
COMPLIANCE. The world needed to do what it promised now. Not in 2020 when the agreement becomes law, or 2025 when it is first reviewed, but now.
JUSTICE. Those worst affected must be compensated by those that polluted most.
FINANCE. The rich countries must pay the poor countries so they can develop without fossil fuels.
EQUITY. We must all have the same right to emit, rich or poor.
And finally an immediate, drastic and urgent cut in EMISSIONS. That meant no new fossil fuels.
So were we surprised when, before the ink was dry, our government licensed huge chunks of England for fracking? No. We knew this was the next battle we would have to fight: in Lancashire, in Yorkshire and here in Manchester.
Fracking is a toxic nightmare, it will frack our countryside, it will frack our water and it will frack our health, but it will above all frack our climate.
It is a new fossil fuel. Fracking does not keep coal in the ground. The fracking did cause US coal use to drop, but US coal exports increased by even more.
But as well as being a new fossil fuel, and as well as the fugitive emissions, fracking will lock us into a new generation of fossil fuel power stations. A gas fired power station will last for thirty years, which means the infrastructure being planned now will could still be polluting in 2050, long after the UK fracking boom will have ended even if the industry's most optimistic forecasts are right.
We know what the alternatives is. It's wind and wave and solar. It's jobs and clean air and energy security. It's public transport and warm houses and fewer private jets. It's a sane, humane and ecological future.
It will happen.
It must happen.
But it isn't going to be easy.
