Abstract

Scenario pathways greatly inform the opportunity space of possible future climates. The multistep experiment tests the Alternative Method to Determine a Carbon Dioxide Removal Target’s thesis by simulating the novel pathway '300x2050,' SSP1-2.6, and SSP1-1.9 comparing within green growth development in MAGICC 6.8 by removing all cumulative anthropogenic CO₂ over 80 years and phasing out anthropogenic GHGs. Contrary to the previous theory, the experiment removed carbon equal to accumulated fossil fuels and land-use change emissions, realizing a final temperature of 0.07ºC relative to 1720-1800, 0.14ºC to the 1850-1900 mean, and CO₂ concentration of 278.82 ppm by 2550. The vast CDR needed to approximate the speculation of Anthropocene reversal by 2100 justifies utmost urgency and maximally scaled sustainable (zero-carbon intensity) green growth development.
