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

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.

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.

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

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.
