At the other extreme is it's a leading researcher into experimental areas like decadal modelling.
He also acknowleged a failure to respond promptly to media requests for clarification of the decadal study.
If you started the bet any year during the 1980s Simon won eight of the ten decadal start years.
It happened after bloggers seized on a Met Office paper revising downward its decadal global temperature projection for 2017.
"For multi-decadal variability, over the historical period, the major cause was aerosols as opposed to climate change or ocean acidification, " he explained.
BBC: Particles from fossil fuels 'affect the growth of corals'
Decadal and longer changes in sunspot activity impacting warming and cooling cloud cover patterns are now being recognized as an important factor.
In his column for the BBC News website, BBC Environment Analyst Roger Harrabin assesses the fall-out from the row over Met Office decadal forecasting.
No, as generally recognized, climate changes are measured in multi-decadal timescales.
FORBES: Election Campaigns Prove Global Warming Crisis Skeptics Won The Climate Debate
Mike's may have slightly less variability on decadal scales than the others (especially cf Esper et al), but he is using a lot more data than the others.
It describes the decadal projections as part of an experimental effort launched in 2004 to fill the gap between daily weather forecasts and century-long estimates for climate change.
The global temperature trends since then have followed not rising CO2 trends but the ocean temperature cycles of the Pacific Decadal Oscillation (PDO) and the Atlantic Multidecadal Oscillation (AMO).
FORBES: To The Horror Of Global Warming Alarmists, Global Cooling Is Here
The rapid meltback this year is probably due to anomalous weather patterns over the Arctic which have brought temperatures one to three degrees above the decadal averages for 1981-2010.
Much of the variability in global TC ACE is explained by the concomitant changes or evolution in the character of the El Nino Southern Oscillation (ENSO) and Pacific Decadal Oscillation (PDO).
FORBES: Yes, There's A Link Between Hurricane Irene And Global Warming
Climate is a system that we know to have seasonal, annual, decadal, and even thousand and ten-thousand year cycles, which we have only really observed in earnest for thirty years or so.
FORBES: Truthmarket Challenge Demonstrates Everything That Is Wrong With the Global Warming Debate
No one can even forecast global, national or regional weather conditions that will occur months or years into the future, much less climate shifts that will be realized over decadal, centennial and longer periods.
FORBES: Climate Forecasting Models Aren't Pretty, And They Aren't Smart
However, in the paper I did show that once the proposed model was calibrated from 1850 to 1950, it has been able to reproduce the decadal and multi-decadal modulation of the temperature observed from 1950 to 2011, and vice versa.
FORBES: Global Warming? No, Natural, Predictable Climate Change
Instead, the temperature record shows an up and down pattern that follows the pattern of natural influences on global temperatures, such as cyclical sunspots and solar flares, and cycles of ocean churning from warmer to colder temperatures and back, such as the Pacific Decadal Oscillation (PDO).
FORBES: Fakegate: The Obnoxious Fabrication of Global Warming
This precipitous decline in the quantity of Earth science and applications observations from space undertaken by the United States reinforces the conclusion in the decadal survey and its predecessor, the 2005 interim report (NRC, 2005), which declared that the U.S. system of environmental satellites is at risk of collapse.
