Carbon dioxide and climate impulse response functions for the computation of greenhouse gas metrics:a multi-model analysis
Abstract. The responses of carbon dioxide (CO2) and other climate variables to an emission pulse of CO2 into the atmosphere are often used to compute the Global Warming Potential (GWP) and GlobalExpand

Detection of climate system bifurcations by degenerate fingerprinting
[1] A method is introduced to estimate the proximity of climate sub-systems to non-linear thresholds. We suggest to measure the smallest decay rate of the system under investigation and to considerExpand

Present state of global wetland extent and wetland methane modelling: conclusions from a model inter-comparison project (WETCHIMP)
Abstract. Global wetlands are believed to be climate sensitive, and are the largest natural emitters of methane (CH4). Increased wetland CH4 emissions could act as a positive feedback to futureExpand

The global methane budget 2000–2012
Abstract. The global methane (CH4) budget is becoming an increasingly important component for managing realistic pathways to mitigate climate change. This relevance, due to a shorter atmosphericExpand

A dynamic model of wetland extent and peat accumulation: Results for the Holocene
Abstract. Substantial deposits of peat have accumulated since the last glacial. Since peat accumulation rates are rather low, this process was previously neglected in carbon cycle models. ForExpand

The Global Methane Budget: 2000–2012
Understanding and quantifying the global methane (CH4) budget is important for assessing realistic pathways to mitigate climate change. Atmospheric emissions and concentrations of CH4 continue toExpand

The potential role of spectral properties in detecting thresholds in the Earth system: application to the thermohaline circulation
Abstract A simple two-box model of the hemispheric thermohaline circulation (THC) is considered. The model parameterizes fluctuations in the freshwater forcing by a stochastic process. The dependenceExpand

Expert assessment of vulnerability of permafrost carbon to climate change
Approximately 1700 Pg of soil carbon (C) are stored in the northern circumpolar permafrost zone, more than twice as much C than in the atmosphere. The overall amount, rate, and form of C released toExpand

WETCHIMP-WSL: intercomparison of wetland methane emissions models over West Siberia
Abstract. Wetlands are the world's largest natural source of methane, a powerful greenhouse gas. The strong sensitivity of methane emissions to environmental factors such as soil temperature andExpand

Holocene evolution of the Southern Hemisphere westerly winds in transient simulations with global climate models
The Southern Hemisphere Westerly Winds (SWW) have been suggested to exert a critical influence on global climate through the wind-driven upwelling of deep water in the Southern Ocean and theExpand
