"We need to focus every inch of our being on climate change, because if we fail to do so than all our achievements and progress have been for nothing and all that will remain of our political leaders’ legacy will be the greatest failure of human history. And they will be remembered as the greatest villains of all time, because they have chosen not to listen and not to act."

“Ingels: I shouldn't be up here. I should be back in school on the other side of the ocean. Yet you all come to us young people for hope. How dare you. You have stolen my dreams and my childhood with your empty words.”

“There are no emergency meetings, no headlines, no breaking news. No one is acting as if we were in a crisis. Even most climate scientists or green politicians keep on flying around the world, eating meat and dairy. … Today we use 100 million barrels of oil every single day. There are no politics to change that. There are no rules to keep that oil in the ground. So we can't save the world by playing by the rules. Because the rules have to be changed. Everything needs to change. And it has to start today.”

“One person stops flying doesn’t make much difference. The thing we should look at is the emissions curve—it’s still rising. Of course something is happening, but basically nothing is happening. The change is going to come from the people demanding action, and that is us.”

“Avoiding climate breakdown will require cathedral thinking. We must lay the foundation while we may not know exactly how to build the ceiling.”

“I have Asperger's syndrome and that means I'm sometimes a bit different from the norm. And - given the right circumstances - being different is a superpower. It makes you think differently. And especially in such a big crisis like this one we need to think outside the box. We need to think outside our current system, that we need people that think outside the box and who aren't like everyone else.”

“You lied to us. You gave us false hope. You told us that the future was something to look forward to. And the saddest thing is that most children are not even aware of the fate that awaits us. We will not understand it until it’s too late. And yet we are the lucky ones. Those who will be affected the hardest are already suffering the consequences. But their voices are not heard.”
