Hot House Earth

Trajectories of the Earth System in the Anthropocene, a recent study coauthored by Will Steffen, noted chemist, climate systems analyst, and professor of Earth System Science at Australian National University, warns of catastrophic changes to the Earth climate if current emission trends are not immediately reversed. The, HotHouseEarth scenario an existential crisis in which fundamental climate systems, and the ecosystems that rely on them, are irreversibly altered is not only possible, but likely, if current trajectories persist. We will then enter a new geological age, perhaps we can call it the, Idiocene , TippingPoints lead to, TippingCascades, and the resulting failure of intertwined systems leading to systemic collapse. While it is already too late to fully reverse the impact of the humanity s Anthropocene foolishness and greed, the current geological age characterized by human activity, it is still possible to guide the climate trajectory toward a ne
