Humanity can still limit global warming to 1.5°C this century. But political action will determine whether it actually does. Conflating the two questions amounts to dangerous, misplaced punditry.
Several countries have made pledges to reduce their greenhouse gas emissions to zero by mid-century. But new research finds the remaining carbon budget will be depleted before we get there.
To limit warming to 1.5°C above pre-industrial levels, we’ll need to cut global emissions by 7.6% each year this decade. It’s difficult, but not impossible.
The climate emergency requires the full mobilisation of scientific institutions, but the persistent compartmentalization between disciplines and difficulties of adaptation hinder their action.
Nations are signed up to limit global heating to well below 2°C, and to aim for 1.5°C. Limiting warming to the latter matters - the future of humanity and the living world is at stake.
Whether to attending a conferences or giving in to a meeting, the global research community is keen on air travel. That’s a habit that needs to change.
