Reference excerpt

Rosanne D'Arrigo is a professor at Lamont–Doherty Earth Observatory at Columbia University known for her research into climate change using dendrochronology, or dating based on tree rings.

Education and career D'Arrigo grew up in the Bronx and describes herself as a "winter weather enthusiast" when large amounts of snow required shoveling and kept her home from school. She earned her bachelors' degree and her M.A. (1980) from the State University of New York at Binghamton. She returned to New York City and became the first graduate student in Lamont–Doherty Earth Observatory's Tree Ring Laboratory where she was one of the few women working in the field on tree ring research. Her graduate class work included classes in geology and climate courses, and in 1989 she completed her Ph.D. from Columbia University. In 2019, D'Arrigo was elected a fellow of the American Geophysical Union who cited her "for insightful, rigorous, and original contributions to the development of high-resolution paleoclimatology, particularly dendroclimatology".

Research D'Arrigo is known for her research into past climate and atmospheric conditions using tree rings, a research area called dendroclimatology. Her research includes investigations into the Asian monsoon and the impact of volcanic activity on the rainfall in Asia, linking cool weather in Scotland during the 1690s with volcanic activity, and connecting temperatures in the tropics with volcanic eruptions. Using tree-ring data from trees in Canada and Alaska, D'Arrigo has established a timeline for annual temperatures in North America over the past 300 years. In Alaska, her research has shown that cool years follow volcanic activity. During the 2009 controversy on climate change, D'Arrigo's noted that her research dating to 1995 had already published details on the divergence problem, which is the issue where warming since the 1950s does not appear in tree ring datasets. In 2020, D'Arrigo was part of the team that assessed the potential for future flooding of the Brahmaputra River under future climate change.

Worked examples

Example 1 — a first encounter with Rosanne D'Arrigo

Start with the simplest possible case. Write down what Rosanne D'Arrigo claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Rosanne D'Arrigo before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Rosanne D'Arrigo ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Rosanne D'Arrigo

In research: Rosanne D'Arrigo appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Rosanne D'Arrigo in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Rosanne D'Arrigo is common in secondary-school and first-year university syllabi. It links to neighbouring topics Binghamton University alumni, Columbia University alumni, Fellows of the American Geophysical Union, so understanding it makes those chapters shorter.
In everyday life: Look for Rosanne D'Arrigo outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
