University of California San Diego Professor of Physics Thomas Murphy believes that although no one can say with absolute certainty that the planet will reach an unavertable crisis by the end of this century, our current trajectory is unable to continue much longer. His assessment appears in a comment paper recently published by Nature Physics.

Trained as an astrophysicist, Murphy became interested in planetary limits after teaching a class on energy and the environment. Students explored the physics of energy, how to calculate energy demand and resources and the resulting environmental impacts. Murphy realized the issues of resource and energy consumption were more severe than many assumed.
