The scientists used their findings from the 2003 — 2005 data in a simple model to estimate changes in wetland methane emissions from 2003 — 2007.

Present state of global wetland extent and wetland methane modelling: Conclusions from a model inter-comparison project (WETCHIMP)
By Dr Jennifer Muller, University of Manchester The last day of the August aircraft MAMM campaign (19 August) was all about sampling the methane closer to home as well as actually getting back to Cranfield; leaving the Arctic wetland methane behind us (until the September campaign of course).
Furthermore, we participate in process model studies for estimating wetland methane emissions.
Scientists assumed that wetland methane release was largest in the tropics, said Professor Turetsky.
Doubled CO2 simulations using this model show an increase in annual average wetland methane emissions from 156 to 277 Tg / yr, a rise of 78 %.
This finding supports the Rhodes et al. hypothesis that increased rainfall in the southern tropics likely stimulated wetland methane emissions in response to massive iceberg discharge events during the last glacial period.
It is also a modest source of methane (CH4): between 15 and 50 Tg (CH4) / yr are emitted mostly from seasonally unfrozen wetlands corresponding to about 10 % of the global wetland methane source.
