The time is past when humankind thought it could selfishly draw on exhaustible resources. We know now the world is not a commodity, is not a source of revenue; it’s a common good, it’s our heritage. And the consequences of climate change are fully known now – we’re not talking about theories anymore, we’re talking about certainties.

This is all wrong. 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. And yet I’m one of the lucky ones. People are suffering. People are dying. Entire ecosystems are collapsing. We are in the beginning of a mass extinction, and all you can talk about is money and fairy tales of eternal economic growth. How dare you!

Climate change is a global problem. The planet is warming because of the growing level of greenhouse gas emissions from human activity. If this trend continues, truly catastrophic consequences are likely to ensue from rising sea levels to reduced water availability, to more heat waves and fires.
