Taoiseach: Climate change is the most serious challenge of our lifetime

Taoiseach Micheál Martin arrives for the Cop26 summit at the Scottish Event Campus in Glasgow. 

Climate change is “without doubt” the most serious challenge in our lifetime, an existential crisis if it is not tackled with action instead of rhetoric.

Those were the words of Taoiseach Micheál Martin as the United Nations Cop26 climate change event in Glasgow began, with world leaders descending on the Scottish city on Monday.
