Grantchester star James Norton has teamed up with The Climate Coalition, lending his voice to its Show The Love campaign video, calling on people to make combating climate change 'the next great human achievement'.

The British actor commented 'If we all try to make changes in our lives while using our power to influence those who can make the world of difference then, as it says in the film, we can be the generation that achieves the greatest of all humanity’s successes'.
