چکیده

Research Institute of Electric Power Industry jointly with National Center for Atmospheric Research. To contribute to the IPCC Fourth Assessment Report, multi-century global warming projections based on the IPCC SRES scenarios were conducted using the Earth Simulator. One of the features of our experiments is multi-century long-term projections under the stabilized radiative forcings of greenhouse gases. In addition, simple overshoot scenarios are proposed and hysteresis effects in climate system were investigated.

Global Climate Models and 20th and 21st Century Arctic Climate Change

We review the history of global climate model (GCM) development with regard to Arctic climate beginning with the ACSYS era. This was a time of rapid improvement in many models. We focus on those aspects of the Arctic climate system that are most likely to amplify the Arctic response to anthropogenic greenhouse gas forcing in the 20th and 21st centuries. Lessons from past GCM modeling and the mo...

Climate impacts of energy technologies depend on emissions timing

Energy technologies emit greenhouse gases with di�ering radiative e�ciencies and atmospheric lifetimes1–3. Standard practice for evaluating technologies, which uses the global warming potential (GWP) to compare the integrated radiative forcing of emitted gases over a fixed time horizon4, does not acknowledge the importance of a changing background climate relative to climate change mitigation t...

An integrated assessment modeling framework for uncertainty studies in global and regional climate change: the MIT IGSM-CAM (version 1.0)*

This paper describes a computationally efficient framework for uncertainty studies in global and regional climate change. In this framework, the Massachusetts Institute of Technology (MIT) Integrated Global System Model (IGSM), an integrated assessment model that couples an Earth system model of intermediate complexity to a human activity model, is linked to the National Center for Atmospheric ...

Flexible parameter-sparse global temperature time profiles that stabilise at 1.5 and 2.0 C

The meeting of the United Nations Framework Convention on Climate Change (UNFCCC) in December 2015 committed parties at the convention to hold the rise in global average temperature to well below 2.0 C above pre-industrial levels. It also committed the parties to pursue efforts to limit warming to 1.5 C. This leads to two key questions. First, what extent of emissions reduction will achieve eit...

The upper end of climate model temperature projections is inconsistent with past warming

Climate models predict a large range of possible future temperatures for a particular scenario of future emissions of greenhouse gases and other anthropogenic forcings of climate. Given that further warming in coming decades could threaten increasing risks of climatic disruption, it is important to determine whether model projections are consistent with temperature changes already observed. Thi...
