Climate change: More studies needed on possibility of human extinction
Catastrophic climate change outcomes, including human extinction, are not being taken seriously enough by scientists, a new study says.

The authors say that the consequences of more extreme warming - still on the cards if no action is taken - are "dangerously underexplored".
They argue that the world needs to start preparing for the possibility of what they term the "climate endgame".
They want UN scientists to investigate the risk of catastrophic change.
According to this new analysis, the closest attempts to directly understand or address how climate change could lead to global catastrophe have come from popular science books such as The Uninhabitable Earth and not from mainstream science research.
In recent years climate scientists have more often studied the impacts of warming of around 1.5C or 2C above the temperatures seen in 1850, before the onset of global industrialisation.
These studies show that keeping temperatures close to these levels this century will place heavy burdens on global economies, but they do not envisage the end of humanity.
Researchers have focussed on these lower temperature scenarios for good reasons.
The Paris climate agreement saw almost every nation on Earth sign up to a deal that aims to keep the rise in global temperatures "well below" 2C this century, and make efforts to keep it under 1.5C.
So it's natural that governments would want their scientists to show exactly what this type of change would mean.
But this new paper says that not enough attention has been given to more extreme outcomes of climate change.
