Land-based implications of early climate actions without global net-negative emissions
Delaying climate mitigation action and allowing a temporary overshoot of temperature targets require large-scale carbon dioxide removal (CDR) in the second half of this century that may induce adverse side eff...

Net zero-emission pathways reduce the physical and economic risks of climate change
Mitigation pathways exploring end-of-century temperature targets often entail temperature overshoot. Little is known about the additional climate risks generated by overshooting temperature. Here we assessed t...

A new scenario logic for the Paris Agreement long-term temperature goal
To understand how global warming can be kept well below 2 degrees Celsius and even 1.5 degrees Celsius, climate policy uses scenarios that describe how society could reduce its greenhouse gas emissions. Howeve...
