'Nothing was done to tackle climate change,' says Greta at 50th WEF in Davos

Swedish teen activist Greta Thunberg on Tuesday slammed global inaction on climate change in front of the world’s top business leaders, at the WEF, as the annual Davos forum faced up to the perils of global warming while bracing for an address from US President Donald Trump. Trump, who has repeatedly expressed scepticism about climate change, is set to give the first keynote address of Davos 2020 on Tuesday morning.
