Thousands of students have marched on the Dail this lunchtime to demand action against climate change.
It's part of a number of nationwide events, which seen young people also protest outside their local authorities and school gates.
Those who took part in the day's demonstrations say they have no choice but to demand the Government act, and have issued them with six demands.
They include a crack down on companies contributing to climate change and ensuring Ireland uses 100% renewable energy by 2030.

Today's events come as part of global movement on Climate Action, which was started by a 16 year old Swedish girl.
She started protesting outside the Swedish parliament last year.
Now literally thousands of young people are following in her footsteps.
