Global climate change is the most urgent problem faced by humankind. Professor Will Steffen of the Australian National University and co-authors have shown that the earth is liable to many tipping points, several subject to positive feedbacks.
Unless there is a rapid transition to 100% renewable energy, humankind will lose control of climate change, with the planet entering the Anthropocene era. Severe global warming of 4 - 8 C would disrupt world food supplies, leading to mass starvations, migrations and war.
