Future changes in global warming potentials under representative concentration pathways

Scenario dependence of future changes in climate extremes under 1.5 °C and 2 °C global warming

The 2015 Paris Agreement aims to limit global warming below 2 °C and pursue efforts to even limit it to 1.5 °C relative to pre-industrial levels. Decision makers need reliable information on the impacts caused by these warming levels for climate mitigation and adaptation measures. We explore the changes in climate extremes, which are closely tied to economic losses and casualties, under 1.5 °C ...

Ventilation under global warming

Since the upper ocean takes up much of the heat added to the earth system by an-thropogenic global warming, one would expect that global warming would lead to an increase in stratification and a decrease in the ventilation of the ocean interior. However , multiple simulations in global coupled climate models using an ideal age tracer 5 which is set to zero in the mixed layer and ages at 1 yr/yr...

The representative concentration pathways: an overview

This paper summarizes the development process and main characteristics of the Representative Concentration Pathways (RCPs), a set of four new pathways developed for the climate modeling community as a basis for long-term and near-term modeling experiments. The four RCPs together span the range of year 2100 radiative forcing values found in the open literature, i.e. from 2.6 to 8.5 W/m. The RCPs...

Global Warming Potentials: A Cost-Effectiveness Approach

The Kyoto Protocol prescribes obligatory limits on the emission of greenhouse gases by the industrialized countries during the period 2008-2012. Six specific gases are covered. The Kyoto limits apply to an aggregate of emissions of the covered gases expressed in carbon dioxide (CO2) equivalents, obtained by application of a "global warming potentials" (GWPs). In regard to concentrations, or sto...
