Greta Thunberg warns Davos about climate risks

What she's saying: "With today’s emissions levels, the remaining budget is gone in less than eight years. These aren’t anyone’s views. This is the science."

• "I know you don’t want to talk about this," she said, adding that she has "been repeating these numbers at nearly every speech I’ve given for the last 18 months."
• "Please note that these figures are global and, therefore, do not say anything about about the aspect of equity, which is absolutely necessary to make the Paris agreement work on a global scale."
• "[I]f you see it from another perspective, pretty much nothing has been done since the global emissions of carbon dioxide [have] not reduced. That, of course, is what we are trying to achieve among other things."
