"We understand the world is complicated and that what we are asking for may not be easy or may seem unrealistic. But it is much more unrealistic to believe that our societies would be able to survive the global heating we’re heading for – as well as other disastrous ecological consequences of today’s business as usual... This mix of ignorance, denial and unawareness is at the very heart of the problem... The only way forward is for society to start treating the crisis like a crisis... We can still avoid the worst consequences. But to do that, we have to face the climate emergency and change our ways. And that is the uncomfortable truth we cannot escape."
