'You have not seen anything yet,' climate activist Greta says ahead of Davos
'You have not seen the last of us, we can assure you that. And that is the message that we will bring to the World Economic Forum in Davos next week'
"We are now in a new year and we have entered a new decade and so far, during this decade, we have seen no sign whatsoever that real #climateaction is coming and that has to change," says
before heading to #WorldEconomicForum #Davos2020
