Adjusting 1.5 degree C climate change mitigation pathways in light of adverse new information.

ABSTRACT: Understanding how 1.5 °C pathways could adjust in light of new adverse information, such as a reduced 1.5 °C carbon budget, or slower-than-expected low-carbon technology deployment, is critical for planning resilient pathways. We use an integrated assessment model to explore potential pathway adjustments starting in 2025 and 2030, following the arrival of new information. The 1.5 °C target remains achievable in the model, in light of some adverse information, provided a broad portfolio of technologies and measures is still available. If multiple pieces of adverse information arrive simultaneously, average annual emissions reductions near 3 GtCO₂/yr for the first five years following the pathway adjustment, compared to 2 GtCO₂/yr in 2020 when the Covid-19 pandemic bega
