Malcolm K. Hughes
Malcolm K. Hughes is a meso- climatologist and Regents' Professor of Dendrochronology in the Laboratory for Tree-Ring Research at the University of Arizona. Education and early life Hughes was born in Matlock, Derbyshire, England, and earned a Ph.D in ecology from the University of Durham. Career and research Since 1998, he is a fellow of the American Geophysical Union. His research is on the nature of climate variability, specifically focusing on the timescales of years to centuries. He uses natural recorded records such as tree rings. Hughes has studied geographical areas including Europe, Asia, and the Sierra Nevada. In addition to tree rings, Hughes uses ice cores, laminated sediments, and the historical temperature record to help understand past climates. In 1998, he was a co-author with Michael E. Mann and Raymond S. Bradley on a paper which produced the first eigenvector-based climate field reconstruction (CFR) incorporating multiple climate proxy data sets of d ...

Matlock, Derbyshire
Matlock is the county town of Derbyshire, England. It is situated in the south-eastern part of the Peak District, with the National Park directly to the west. The town is twinned with the French town of Eaubonne. The former spa resort of Matlock Bath lies immediately south of the town on the A6. The civil parish of Matlock Town had a population in the 2011 UK census of 9,543. Matlock is nine miles (14 km) south-west of Chesterfield and in easy reach of the cities of Derby (19 miles), Sheffield (20 miles) and Nottingham (29 miles); the Greater Manchester conurbation is 30 miles away. Matlock is within the Derbyshire Dales district, which also includes the towns of Bakewell and Ashbourne, as well as Wirksworth. The headquarters of Derbyshire County Council are in the town. History The name Matlock derives from the Old English ''mæthel'' (or ''mæðel''), meaning assembly or speech, and ''āc'', meaning oak tree; thus Matlock means 'moot-oak', an oak tree where mee ...

Historical Temperature Record
The instrumental temperature record is a record of temperatures within Earth's climate based on direct, instrument-based measurements of air temperature and ocean temperature. Instrumental temperature records are distinguished from indirect reconstructions using climate proxy data such as from tree rings and ocean sediments. Instrument-based data are collected from thousands of meteorological stations, buoys and ships around the globe. Whilst many heavily-populated areas have a high density of measurements, observations are more widely spread in sparsely populated areas such as polar regions and deserts, as well as over many parts of Africa and South America. Measurements were historically made using mercury or alcohol thermometers which were read manually, but are increasingly made using electronic sensors which transmit data automatically. The longest-running temperature record is the Central England temperature data series, which starts in 1659. The longest-running quasi-globa ...

Alumni Of University College, Durham
Alumni (singular: alumnus (masculine) or alumna (feminine)) are former students of a school, college, or university who have either attended or graduated in some fashion from the institution. The feminine plural alumnae is sometimes used for groups of women. The word is Latin and means "one who is being (or has been) nourished". The term is not synonymous with "graduate"; one can be an alumnus without graduating ( Burt Reynolds, alumnus but not graduate of Florida State, is an example). The term is sometimes used to refer to a former employee or member of an organization, contributor, or inmate. Etymology The Latin noun ''alumnus'' means "foster son" or "pupil". It is derived from PIE ''*h₂el-'' (grow, nourish), and it is a variant of the Latin verb ''alere'' "to nourish".Merriam-Webster: alumnus .. Separate, but from th ...

University Of Arizona Faculty
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. ''University'' is derived from the Latin phrase ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". Universities typically offer both undergraduate and postgraduate programs. The first universities in Europe were established by Catholic Church monks. The University of Bologna (), Italy, which was founded in 1088, is the first university in the sense of: *being a high degree-awarding institute. *using the word ''universitas'' (which was coined at its foundation). *having independence from the ecclesiastic schools and issuing secular as well as non-secular degrees (with teaching conducted by both clergy and non-clergy): grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university in medieval life, 1179–1499", McFarland, 2008, , p. 55f.de Ridder-Symoens, Hild ...

Hockey Stick Graph (global Temperature)
Hockey stick graphs present the global or hemispherical mean temperature record of the past 500 to 2000 years as shown by quantitative climate reconstructions based on climate proxy records. These reconstructions have consistently shown a slow long term cooling trend changing into relatively rapid warming in the 20th century, with the instrumental temperature record by 2000 exceeding earlier temperatures. The term ''hockey stick graph'' was popularized by the climatologist Jerry Mahlman, to describe the pattern shown by the (MBH99) reconstruction, envisaging a graph that is relatively flat with a downward trend to 1900 as forming an ice hockey stick's "shaft" followed by a sharp, steady increase corresponding to the "blade" portion. The reconstructions have featured in Intergovernmental Panel on Climate Change (IPCC) reports as evidence of global warming. Arguments over the reconstructions have been taken up by fossil fuel industry funded lobbying groups attempting to cast do ...

Eigenvalues And Eigenvectors
In linear algebra, an eigenvector () or characteristic vector of a linear transformation is a nonzero vector that changes at most by a scalar factor when that linear transformation is applied to it. The corresponding eigenvalue, often denoted by \lambda, is the factor by which the eigenvector is scaled. Geometrically, an eigenvector, corresponding to a real nonzero eigenvalue, points in a direction in which it is stretched by the transformation and the eigenvalue is the factor by which it is stretched. If the eigenvalue is negative, the direction is reversed. Loosely speaking, in a multidimensional vector space, the eigenvector is not rotated. Formal definition If is a linear transformation from a vector space over a field into itself and is a nonzero vector in , then is an eigenvector of if is a scalar multiple of . This can be written as T(\mathbf) = \lambda \mathbf, where is a scalar in , known as the eigenvalue, characteristic value, or characteristic root ...

Raymond S
Raymond is a male given name. It was borrowed into English from French (older French spellings were Reimund and Raimund, whereas the modern English and French spellings are identical). It originated as the Germanic ᚱᚨᚷᛁᚾᛗᚢᚾᛞ (''Raginmund'') or ᚱᛖᚷᛁᚾᛗᚢᚾᛞ (''Reginmund''). ''Ragin'' (Gothic) and ''regin'' (Old German) meant "counsel". The Old High German ''mund'' originally meant "hand", but came to mean "protection". This etymology suggests that the name originated in the Early Middle Ages, possibly from Latin. Alternatively, the name can also be derived from Germanic Hraidmund, the first element being ''Hraid'', possibly meaning "fame" (compare ''Hrod'', found in names such as Robert, Roderick, Rudolph, Roland, Rodney and Roger) and ''mund'' meaning "protector". Despite the German and French origins of the English name, some of its early uses in English documents appear in Latinized form. As a surname, its first recorded appearance in Bri ...
