Greta Thunberg leaves after Trump speech

Climate activist Greta Thunberg has left the hall after listening to a speech by US President Donald Trump at the Swiss ski resort of Davos.

Earlier, Thunberg and other young activists told the elites gathered at the World Economic Forum they are not doing enough to deal with the climate emergency and warned them that time was running out.

At a panel in Davos, the activists said on Tuesday that they hoped their generation had found its voice and can work with those in power to bring about the necessary change to limit climate change. Yet Thunberg said not enough has been done.
