Greta Tintin Eleonora Ernman Thunberg is a Swedish environmental activist on climate change whose campaigning has gained international recognition. Thunberg is known for her blunt, straightforward speaking manner, both in public and to political leaders and assemblies, in which she urges immediate action to address what she describes as the climate crisis. Greta Thunberg’s urgent message to tackle the climate crisis has sparked a wave of action from the global school strikes to political promises for zero-emission economies. But if we’re serious about Global Goal 13 for climate action, we need to wield our most powerful weapon of all: our vote. With elections coming up in the UK and the US over the next year, Thunberg’s call to engage with our democratic rights couldn’t be more timely.
