Present state of global wetland extent and wetland methane modelling: conclusions from a model inter-comparison project (WETCHIMP)
Global wetlands are believed to be climate sensitive, and are the largest natural emitters of methane (CH 4 ). Increased wetland CH 4 emissions could act as a positive feedback to future warming. TheExpand

Simulating idealized Dansgaard-Oeschger events and their potential impacts on the global methane cycle
Abstract Ice-core records indicate that during the last glacial period, atmospheric CH4 and Greenland temperature rose abruptly in a series of Dansgaard-Oeschger (D-O) events. These increasesExpand

Inference of past climate from borehole temperature data using Bayesian Reversible Jump Markov chain Monte Carlo
SUMMARY Estimates of past climate derived from borehole temperatures are assuming a greater importance in context of the millennial temperature variation debate. However, recovery of these signalsExpand

Present state of global wetland extent and wetland methane modelling: methodology of a model inter-comparison project (WETCHIMP)
The Wetland and Wetland CH4 Intercomparison of Models Project (WETCHIMP) was created to evaluate our present ability to simulate large-scale wetland characteristics and corresponding methane (CH4)Expand

Climate and carbon cycle response to the 1815 Tambora volcanic eruption
[1] The sulphur released by the 1815 Tambora volcanic eruption resulted in a net cooling after the eruption. The cold climate was responsible for crop failures, leading to serious famine and highExpand

Limited response of peatland CH4 emissions to abrupt Atlantic Ocean circulation changes in glacial climates
Ice-core records show that abrupt Dansgaard- Oeschger (D-O) climatic warming events of the last glacial period were accompanied by large increases in the atmo- spheric CH4 concentration (up to 200Expand

Controls on the tropospheric oxidizing capacity during an idealized Dansgaard-Oeschger event, and their implications for the rapid rises in atmospheric methane during the last glacial period
The ice core record reveals large variations in the concentration of atmospheric methane, CH4, over the last 800 kyr. Amongst the most striking natural features are the large, rapid rises in CH4, ofExpand

Evaluation of biospheric components in Earth system models using modern and palaeo observations: the state-of-the-art
Earth system models (ESMs) are increasing in complexity by incorporating more processes than their pre- decessors, making them potentially important tools for studying the evolution of climate andExpand
