KEY POINTS:
Three Greenpeace activists have scaled the roof of a controversial mothballed power station, demanding urgent action on climate change.
The activists said they planned to transmit "climate rescue radio" directly from the 60m roof of the Marsden B power station at Ruakaka, near Whangarei.
It will be broadcast on 88.3 FM to the Whangarei area.
The power station, which gained consent to convert to coal in 2005, is the subject of a Greenpeace legal appeal in the Environment Court.
Greenpeace is beaming "climate rescue radio", Heatwave FM, on the internet and has written an open letter to the Government demanding urgent action on climate change as part of a Global Day of Action.
Today's Global Day of Action on climate change will see people from many groups all over the world demand that world leaders take the urgent action needed to prevent the catastrophic destabilisation of the global climate.
It is timed to coincide with the United Nations Climate meeting on the Kyoto Protocol, in Nairobi from November 6-17.
Celebrity DJ 'Bomber' Bradbury and musician Steve Abel will be hosting Heatwave FM and broadcasting online to the world at www.heatwavefm.net.
They were to cross live to the activists on the roof of Marsden B.
Climate campaigner Vanessa Atkinson said Prime Minister Helen Clark had told New Zealand it was time to be bold on climate change.
"Marsden B is obviously the first thing that the Prime Minister should be axing and any other new coal-fired powers stations.
"Truly sustainable electricity generation comes from renewable energy: sun, wind and water. Not dirty old coal."
She said if Marsden B went ahead it would release over 2 million tonnes of climate polluting gases into the atmosphere every year.
The activists planned to stay on the roof until Tuesday morning.
Greenpeace will be hosting a "climate rescue picnic" outside the front gates of Marsden B on Sunday from 12-3pm.
