The initial hope for climate science was that an improved understanding of what the future might bring would lead to appropriate public policies and effective international climate agreements. Even if that hope is not realized, as now seems likely, scientific advances leading to a more refined...

Climate change is real and dangerous. Exactly how bad it will get, however, is uncertain. Uncertainty is particularly relevant for estimates of one of the key parameters: equilibrium climate sensitivity--how eventual temperatures will react as atmospheric carbon dioxide concentrations double....

An economic approach to calculating the Social Value of Temporary Reductions (SVTR) in atmospheric carbon is discussed. The SVTR allows different carbon removals projects to be prioritised in a way that maximises welfare and establishes equivalence between temporary, risky removals with...
