Mike's work, like that of previous award winners, is diverse, and includes pioneering and highly cited work in time series analysis (an elegant use of Thomson's multitaper spectral analysis approach to detect spatiotemporal oscillations in the climate record and methods for smoothing temporal data), decadal climate variability (the term «Atlantic Multidecadal Oscillation» or «AMO» was coined by Mike in an interview with Science's Richard Kerr about a paper he had published with Tom Delworth of GFDL showing evidence in both climate model simulations and observational data for a 50 - 70 year oscillation in the climate system; significantly Mike also published work with Kerry Emanuel in 2006 showing that the AMO concept has been overstated as regards its role in 20th century tropical Atlantic SST changes, a finding recently reaffirmed by a study published in Nature), in showing how changes in radiative forcing from volcanoes can affect ENSO, in examining the role of solar variations in explaining the pattern of the Medieval Climate Anomaly and Little Ice Age, the relationship between the climate changes of past centuries and phenomena such as Atlantic tropical cyclones and global sea level, and even a bit of work in atmospheric chemistry (an analysis of beryllium - 7 measurements).

Updating this analysis using observational data through 2011 (not even including the 2012 record low sea ice extent), the 32 - year trend (1979 - 2011) is -530 thousand square km per decade, and the 20 - year trend is -700 thousand square km per decade.

In one method, a statistical analysis of observational records was performed (using the KNMI Climate Explorer) to compare this summer's heat with summers during the early part of the century, before global warming played a significant role in our climate.

While the statistics of 30 - year (or longer) NAO trends and associated surface climate impacts can not be reliably determined from the short observational record, we have made use of a simple relationship between the statistics of trends of any length and the statistics of the interannual variability, provided the time series is Gaussian (Thompson et al. 2015).

Such proxy material as tree rings can not be as accurate as instrumental records or detailed reconstructions using a variety of observational material - but there are nevertheless a number of obvious consequences that those who debate climate as either «realists» or «sceptics» need to face when considering this data;

The Monaghan et al. study used the correlation structure in the ERA - 40 reanalysis (Uppala et al. 2005) to define the weights on the observational records that are applied at each gridbox on 1 ° × 1 ° degree regular grid with a kriging method.

Given the short period of the records are the observational estimates of the Hurst exponents stable enough to be used as a test for the models?

We make specific recommendations for using past climate records to improve our understanding of the relationship of radiative forcing to climate change and for developing an observational strategy aimed at continuous monitoring of climate forcing variables for the indefinite future.

I'd even propose a totally selfless design that takes the point of view of a scientist 20 year from now who, endowed with 20 years of observational records, looks back and says, «I wish those 2008 simulations had tried to do this and that; I could assess them now and use the validation to learn what that modeled process is really worth.»
