What scientists say about societal collapse

Prof. TIM LENTON
“Some tipping point thresholds have already been reached, while others are getting closer as global warming continues. Once tipped into a new state, many of these systems will cause further warming – and may interact to form cascades that could threaten the existence of human civilisations.”

Prof. HANS JOACHIM SCHELLNHUBER, August 2018
"Climate change is now reaching the end-game, where very soon humanity must choose between taking unprecedented action, or accepting that it has been left too late and bear the consequences.”

Prof. WILL STEFFEN and colleagues, August 2022
“Could anthropogenic climate change result in worldwide societal collapse or even eventual human extinction? At present, this is a dangerously underexplored topic … yet there are ample reasons to suspect that climate change could result in a global catastrophe.”

Dr JOELLE GERGIS
"It’s extraordinary to realise that we are witnessing the great unravelling; the beginning of the end of things. I honestly never thought I’d live to see the start of what sometimes feels like the apocalypse. The Earth is really struggling to maintain its equilibrium. It’s possible that we are now seeing a cascade of tipping points lurching into action as the momentum of instability takes hold and things start to come apart.”

Prof. KEVIN ANDERSON
"The trend line tells us that we are heading towards 3 to 4 degrees Centigrade of warming across this century – an absolute climate catastrophe, and it’s a catastrophe for all species, including our own... We are locking in very high levels of sea level rise, maybe 7-8  meters. we are changing weather
and rainfall patterns as well as insect pollination of our crops. All of this plays out one disaster after another. We’re talking about society collapse here."

Prof. WILL STEFFEN, June 2020
“Given the momentum in both the Earth and human systems, and the growing difference between the ‘reaction time’ needed to steer humanity towards a more sustainable future, and the ‘intervention time’ left to avert a range of catastrophes in both the physical climate system (e.g., melting of Arctic sea ice) and the biosphere (e.g. loss of the Great Barrier Reef), we are already deep into the trajectory towards collapse.”

Prof. HANS JOACHIM SCHELLNHUBER
If we continue down the present path “there is a very big risk that we will just end our civilisation. The human species will survive somehow but we will destroy almost everything we have built up over the last two thousand years.”

“It is the short term which matters most, what global leaders do in the next three-to-five years will determine the future of humanity”.
