How global heating’s children view the world, 12 years on

In the run-up to the global summit in Glasgow, we revisit families with children - now teenagers - born at the time of the 2009 climate conference

They are entering their teenage years and aspire to bring about positive change when they grow up. But the dreams of these three children, each born in different corners of the world in the weeks leading up to the Copenhagen climate conference in 2009, are beset by worries of how global heating might shape their futures.

Following their births, and again in 2015 ahead of the Paris climate summit, the Observer heard from the families of Maria, Olomaina and Denislania about how they were coping with the impacts of climate change.
