It is worse, much worse than you think. The slowness of climate change is a fairy tale, perhaps as pernicious as the one that says it isn’t happening at all

– Journalist David Wallace-Wells, and Author of the Uninhabitable Earth: Life After Warming


Experts agree that global heating of 4C by 2100 is a real possibility. The effects of such a rise will be extreme and require a drastic shift in the way we live. Drowned cities; stagnant seas; intolerable heatwaves; entire nations uninhabitable… and more than 11 billion humans. A four-degree-warmer world is the stuff of nightmares and yet that’s where we’re heading in just decades –

Freelance science reporter Gaia Vince, The Guardian

This is not saying that disaster occurs the next day. it’s saying that, if left unchecked, the carbon cycle would move into a realm which would be no longer stable, and would behave in a way that would be difficult to predict. In the geologic past, this type of behavior is associated with mass extinction.

– Daniel Rothman – a professor of geophysics in the MIT Department of Earth, Atmospheric and Planetary Sciences and the co-director of MIT’s Lorenz Center 


The climate crisis is our third world war. It needs a bold response.

– Joseph E. Stiglitz American economist, public policy analyst, and a professor at Columbia University. He is a recipient of the Nobel Memorial Prize in Economic Sciences (2001) 


We face a direct existential threat. Climate change is moving faster than we are – and its speed has provoked a sonic boom SOS across our world. If we do not change course by 2020, we risk missing the point where we can avoid runaway climate change, with disastrous consequences for people and all the natural systems that sustain us.

– UN Secretary-General António Guterres


Nature is declining globally at rates unprecedented in human history – and the rate of species extinctions is accelerating, with grave impacts on people around the world now likely.

– Greta Thurnberg


It really isn’t an exaggeration to say that the future of the human race is now at stake. The nature of the changes in climate and environment that we are now living with threaten not only the well- being but, possibly, also the being of our species and this planet in the long term. In the middle term, they threaten some of the most vulnerable populations on earth.

– Dr rowan Williams, former archbishop of Canterbury

Without a doubt (climate change) is a huge threat to human civilization. it’s the details that we need to pin down.

– Andrew King, a climate science lecturer at the University of Melbourne


The overwhelming evidence of the IPBES Global Assessment, from a wide range of different fields of knowledge, presents an ominous picture. The health of ecosystems on which we and all other species depend is deteriorating more rapidly than ever. We are eroding the very foundations of our economies, livelihoods, food security, health and quality of life worldwide.”

– Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) Chair, Sir Robert Watson.


By polluting the oceans, not mitigating CO2 emissions, and destroying our biodiversity — we are killing our planet. Let us face it. There is no planet B.

The world is reaching the tipping point beyond which climate change may become irreversible. If this happens, we risk denying present and future generations the right to a healthy and sustainable planet – the whole of humanity stands to lose.

– Kofi Annan Former United Nation secretary general


It’s not that the world hasn’t had more carbon dioxide, it’s not the world hasn’t been warmer.  The problem is the speed at which things are changing.  We are inducing a sixth mass extinction event kind of by accident and we don’t want to be the extinctee, if I may coin this noun.

– Bill Nye, ‘The Science Guy’

The pace of global warming is accelerating and the scale of the impact is devastating. The time for action is limited – we are approaching a tipping point beyond which the opportunity to reverse the damage of CO2 emissions will disappear.

– Eliot Spitzer


The big damages come if the climate sensitivity to greenhouse gases turns out to be high [causing greater global warming than current projections.] Then it’s not a bullet-headed at us, but a thermonuclear warhead. 

– Raymond T. Pierrehumbert


First, I worry about climate change. It’s the only thing that I believe has the power to fundamentally end the march of civilization as we know it, and make a lot of the other efforts that we’re making irrelevant and impossible  

– Bill Clinton Former United States President


Without urgent measures to rapidly reduce our greenhouse gas emissions, the possibility of limiting the temperature rise below a dangerous level will have disappeared within a decade.

– Al Gore Former Vice President of the United States


The planet will continue to cook.   

– Paul Krugman


One problem facing humanity is now so urgent that, unless it is resolved in the next two decades, it will destroy our global civilization: the climate crisis.  It seems almost superfluous to say it, but the warming trend is real and accelerating, and it’s our pollution that is responsible. All but the most ignorant and biased of sceptics now admit this truth, and it’s underlined by the findings of the Intergovernmental Panel on Climate Change [the IPCC]

– Dr. Tim Flannery, Australian of the Year in 2007.


While human-induced global warming is not going to turn present-day Earth into present-day Mars, global warming is dire enough that our most distinguished scientists recently concluded that as many as 1 million species on the planet could be extinct by 2050 if affairs do not change.  

– Jay Inslee


Want to testify today about what I believe is a planetary emergency – a crisis that threatens the survival of our civilization and the habitability of the Earth. 

– Al Gore Former Vice President of the Unites States


Planetary warming is one of several existential threats to human civilization. We are now in the climate end-game, facing a choice between dramatic action or a world plunged into outright chaos. The consequences of a failure to respond appropriately to the risks are explored in a scenario that illustrates the impacts of poorly-mitigated fossil fuel use over the next 50 years, including massive disruption of human societies, and identifies the main causes of the epochal failure of governments to protect the people and their future.

– David Spratt


Climate change is our generation’s greatest environmental challenge. It threatens our economy, our Western way of life and our future. It will change every facet of our existence, and unless we adapt to it, the results will be catastrophic for years to come.

– Gov. Bill Ritter
