"The time to act is now and we are calling on the Irish public to deliver a political message that our country should lead the response to climate change."

The Green Party recently unveiled a 15m banner with the slogan "Climate change: it's time to act" on the Millennium Bridge in Dublin to mark the publication of the IPCC report and the launch of a post card campaign.

The postcards, addressed to the Taoiseach, read:

"Climate change is the greatest challenge facing mankind. I am willing to play my part but I also want your Government to show leadership. Please act now by:

Building more public transport so I can travel quicker and cleaner;
Improving building regulations so that every building is energy efficient;
Investing in renewable energy systems so I use less fossil fuels;
Reforming the tax system so that the polluter pays;
Giving farming a future by promoting forestry and lower emission crops;
We have a decade to meet this challenge, it is time for you to act."
