Why the Paris climate target is feasible in theory but not in practice
By
Glen Peters, Center for International Climate Research (CICERO)
Summary
The article critically examines the feasibility of the Paris Climate Agreement's goal to limit global warming to "well below" 2 degrees Celsius. The author argues that while climate models suggest this target is theoretically achievable, in practice it is not feasible because we have already emitted too much carbon dioxide. The pathways required to stay within this limit would demand removing CO2 from the atmosphere at an unprecedented and likely impractical scale. The piece references a study in Nature Geoscience that claims feasibility, but the author remains skeptical about real-world implementation.

We have essentially emitted too much carbon dioxide already, and the most feasible pathways to stay 'well below' two degrees all require removing carbon dioxide from the atmosphere at an unprecedented scale.
A study published in Nature Geoscience suggests that it could indeed still be feasible.
