I'm on top of a coal train right now with 49 ordinary people, who believe so passionately that we need to stop climate change, we've stopped a train reaching Cottam power station in Nottinghamshire. We flagged it down at 2.30pm and right now, we’re shovelling coal off the train.
It’s pretty dirty work but I’m here with good friends, and we know it’s the right thing to do.
At this same exact moment, thousands of miles away in New York, global leaders are coming together for a hugely important meeting about the climate.
But while world leaders like David Cameron talk, there’s a plan to give energy companies in the UK millions of pounds of tax-payers' money to keep old coal power plants burning.
