Scientific Case for Avoiding Dangerous Climate Change to Protect Young People and Nature


Abstract in English

Global warming due to human-made gases, mainly CO2, is already 0.8{deg}C and deleterious climate impacts are growing worldwide. More warming is in the pipeline because Earth is out of energy balance, with absorbed solar energy exceeding planetary heat radiation. Maintaining a climate that resembles the Holocene, the world of stable shorelines in which civilization developed, requires rapidly reducing fossil fuel CO2 emissions. Such a scenario is economically sensible and has multiple benefits for humanity and other species. Yet fossil fuel extraction is expanding, including highly carbon-intensive sources that can push the climate system beyond tipping points such that amplifying feedbacks drive further climate change that is practically out of humanitys control. This situation raises profound moral issues as young people, future generations, and nature, with no possibility of protecting their future well-being, will bear the principal consequences of actions and inactions of todays adults.
