2 Geoengineering scenarios

The Geoengineering Model Intercomparison Project (GeoMIP) is a project to predict the effects of geoengineering using the world’s climate models. The scientists use scenarios of future human-caused changes in greenhouse gas concentrations accompanied by geoengineering actions that are intended to cancel their effects on climate, to predict the effects of these actions.

Imagine for a moment you are a climate modeller in this project. You attend a meeting with policy-makers and, while getting a coffee before it starts, find yourself standing next to the current UK government minister responsible for energy and climate Change. They ask you: ‘So, what’s the latest from GeoMIP?’.

You will develop your response in the next sections.
