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).

Since our observational record is far to short to have documented any D - O event previously, we could be «blindsided» by the onset of such a phenomenon.

A typo in mine at # 25 is where 40,000 m3 should read 400,000 m3, and an addendum is the reference for the forcing from the Albedo Loss feedback shown in the satellite record: «Observational determination of albedo decrease caused by vanishing Arctic sea ice» See: http://eisenman.ucsd.edu/publications/Pistone-Eisenman-Ramanathan-2014.pdf

And I'd have to say that if I have to save my life by winning an argument with oil men in a bar in Midland, Tex., on this topic, I would go in with some lumps of black mudstone from the ancient rock record, I'd go in with the established figures on our present input of carbon dioxide, and I'd say which bit of this observational science do you guys quarrel with, and why?

The day - by - day, month - by - month, year - by - year, etc. sequencing of values, however, will not correspond to observations, since climate models solve a «boundary value problem» and are not constrained to reproduce the timing of natural climate variability (e.g., El Niño - Southern Oscillation) in the observational record.

According to NOAA's 2016 Arctic Report Card, the average annual surface air temperature anomaly (+3.6 °F / 2.0 °C relative to the 1981 - 2010 baseline) over land north of 60 ° N between October 2015 and September 2016 was by far the highest in the observational record beginning in 1900.

Observational records show that anthropogenic - influenced climate change has already had a profound impact on global and U.S. warm season climate over the past 30 years, and there is increasing contrast between geographic regions that are climatologically wet and dry - the hypothesis that the «wet gets wetter, dry gets drier» is seen in a new paper by Chang et al..

It is likely that all of these have left their mark on the climate signal, but the room within which they may have operated is limited by the reasonably close approximation between the known non-chaotic signals and the observational record.

«To some extend», because the limited length of the observational record does not allow any estimate of very rare events, which in contrast can be done by a long model integration.

Individual observational temperature records are represented by coloured lines.

By these measures, the CESM - LE produces a credible NAO, given the length of the observational record available for assessment.

The observational record, which of course was affected by these other variables, showed a greater divergence from a smooth curve during some intervals, but the difference from the simulations was not extreme.

The uncertainties in the observational records are discussed in detail in Section 3.4.1 and by Karl et al. (2006).

The more direct measure of global warming provided by measuring the energy content of the climate system avoids many of these problems, although the observational record is shorter and less complete (e.g. Church et al 2011).

The study of solar cycles and their climatic effect is hampered by a very short observational record (~ 400 years), an inadequate understanding of the physical causes that might produce centennial to millennial changes in solar activity, and an inadequate knowledge of how such changes produce their climatic effect.

This technical document provides guidelines with the aim to provide managers and operators of climate monitoring networks with a set of recommended procedures / practices by which change can be managed in the observational programs in a manner that best maintains the required integrity of the climate record.
