Non-CO2 forcing changes will likely decrease the remaining carbon budget for 1.5 °C

Abstract One key contribution to the wide range of 1.5 °C carbon budgets among recent studies is the non-CO 2 climate forcing scenario uncertainty. Based on a partitioning of historical non-CO 2 forcing, we show that currently there is a net negative non-CO 2 forcing from fossil fuel combustion (FFC... View More
