The RESCUE project will improve knowledge and understanding of the “Climate and Earth System responses to climate neutrality and net negative emissions” by pursuing two overall objectives:
- Quantify the climate and Earth system responses to pathways achieving climate neutrality by Carbon Dioxide Removal (CDR) deployment with and without temperature overshoot, and
- Assess the potential role of CDR in reducing net greenhouse gas emissions and its potential environmental risks and co-benefits.
To achieve the first objective, RESCUE will design a suite of new global temperature stabilization scenarios at several target values. These new pathways to climate neutrality will consider multiple aspects of the climate system response, such as sea-level rise, carbon cycling, biodiversity, and ecosystem services. On focus is the reversibility of induced changes by comparing scenarios with and without temporary temperature overshoots.
The Alfred-Wegener-Insitute on Polar and Marine Research, in collaboration with the Danish Meteorological Institute, will perform ice sheet simulations to assess the sea-level consequence of various scenarios. In addition, we will evaluate if overshoot scenarios may lead to irreversible changes in the Greenland and Antarctic Ice Sheets, driving a sustained sea-level rise.
