Interesting paper on combining CDR and SRM

[H simmens]

A 2019 paper argues that CDR and SRM used to address peak shaving creates a double debt that can be compared to subprime lending. 

From the abstract:

• “The slow progress of mitigation increases the attraction of an ‘overshoot and peak-shaving’ scenario which combines temporary SRM with large-scale CDR

• Following the logic of debt, the role of CDR and SRM in this scenario is to compensate for delayed mitigation, creating a double debt of CO2 emissions and global temperature

• Using the analogy of subprime lending, this strategy can be seen as offering a combination of subprime mortgage and open-ended ‘line-of-credit’

• Because the ‘success’ of peak-shaving by temporary SRM hinges critically on the overshoot promise of large-scale CDR, SRM and CDR should not be discussed separately”
