President Higgins: All of us must act now on climate catastrophe

We are at the precipice of a global ecological catastrophe and the window of opportunity to act is closing worryingly fast, the President has warned.

Michael D Higgins also told climate crisis activists who range in age from 18 to 80 that if they want to make a significant impact in the battle to save the planet and life on it, they will have to address the issue of power and face down powerful interests.
