This paper describes an integrated assessment model with an unknown temperature threshold where severe and irreversible climate impacts, called a tipping point, occurs. The possibility of tipping leads to the following linked outcomes: a prolonged period of peak temperature; a rebound in...

Optimal climate policy is studied in a Ramsey growth model with exhaustible oil reserves, an infinitelyelastic supply of renewables, stock-dependent oil extraction costs and convex climate damages. Weconcentrate on economies with an initial capital stock below that of the steady state of the...

Die Rubrik »Kurz zum Klima« erscheint nun bereits seit drei Jahren mit nahezu 60 Ausgaben. Dieser Beitrag greift drei Themen aus den Bereichen Energie-, Klima- und Umweltpolitik – das Reserven-Produktions-Verhältnis, die weltweite CO2-Reduktion und das Problem der Überfischung – erneut...

Methane abatement and geoengineering have a short-lived effect on temperature compared with carbon abatement. Different optimal tax paths for these actions arise in a cost-benefit framework with an unknown temperature threshold where severe and irreversible climate impacts, called a tipping...

Global regulations involving clean energy technologies have evolved in recent decades. Such evolution came as a result of technological disparities between the North and the South. Such regulatory changes came because of the failure of developed nations to assist developing countries in...

We conduct a sensitivity analysis to describe conditions under which liquid fuel producers would fund the development of a climate backstop. We estimate (1) the cost to develop competitively priced direct CO₂ air capture technology, a possible climate backstop and (2) the effect of this...

This article explains why policy makers should seriously consider substantial early reductions in greenhouse gas emissions as a part of any post-Kyoto framework, and sets out suggested elements of a framework for early action in a post-Kyoto agreement. Substantial early reductions are needed...
