Peter Kalmus (climate scientist) is a earth science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Peter Kalmus (climate scientist) rather than just read about it. In short: Peter Kalmus (born May 9, 1974) is an American scientist and writer. He is a data scientist at NASA's Jet Propulsion Laboratory as an associate project scientist at UCLA's Joint Institute for Regional Earth System Science & Engineering.

Key takeaways

  • Peter Kalmus (climate scientist) belongs to earth science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Peter Kalmus (climate scientist) to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Peter Kalmus (climate scientist) from memory before moving on to harder problems.

Reference excerpt

Peter Kalmus (born May 9, 1974) is an American scientist and writer. He is a data scientist at NASA's Jet Propulsion Laboratory as an associate project scientist at UCLA's Joint Institute for Regional Earth System Science & Engineering. In addition to his scientific work, he is the author of the book, Being the Change: Live Well and Spark a Climate Revolution. A documentary by the same title complements the book. In addition to authoring articles about climate change, he is the founder of the website noflyclimatesci.org and co-founder of the app, Earth Hero: Climate Change.

Education and early career Kalmus attended Harvard University, where he received his Bachelor of Science in physics in 1997. At Harvard, he used Fourier-transform microwave spectroscopy to discover and categorize the quantum-mechanical rotational spectra of several cyanopolyynes which were subsequently found in interstellar clouds. He then taught high school physics in Massachusetts and wrote software in New York City. In 2004 he enrolled in graduate school at Columbia University and received his PhD in physics in 2008. His PhD work involved searching for gravitational waves as a member of the LIGO Scientific Collaboration (thesis: "Gravitational Waves Associated with Soft Gamma Repeater Flares"). He continued his work with LIGO as a postdoctoral scholar at the California Institute of Technology, leading major full-collaboration searches for gravitational waves from magnetars, gamma ray bursts and supernovae and contributing to the precise calibration of the world's gravitational wave observatories.

Research After focusing on LIGO related work for several years, Kalmus's focus transitioned into earth and climate science. Kalmus's recent research centers on cloud physics, specifically improving basic understanding of marine stratocumulus clouds and severe convective weather such as tornadoes with the goal of improving projections of how these phenomena will change as the planet heats, using remote sensing data, in situ data, and models. Marine stratocumulus clouds reflect incoming sunlight, cooling the planet, and are difficult to model accurately in climate models; this makes them a major source of uncertainty in climate projections. A common thread in his research is improving the utility of satellite observations of the Earth. His work on severe weather unlocks the potential of polar orbiting satellites to observe rapidly changing convective environments by using air parcel trajectory modeling to span the temporal gap between satellite overpass and convective initiation. He has used in situ data from a ship-based campaign to bias-correct the CloudSat warm rain retrieval. He also uses in situ data to validate retrievals from the AIRS instrument on the Aqua (satellite). Kalmus also works in the nascent field of ecological forecasting. Coral reefs are rapidly succumbing to ocean heat waves and ocean acidification. Kalmus is the principal investigator on a NASA grant to study the projected future of the world's coral reefs with improved accuracy and higher resolution. He has co-authored over 100 peer-reviewed scientific articles in physics and Earth science, with a majority having come from his previous participation in the LIGO Collaboration.

Worked examples

Example 1 — a first encounter with Peter Kalmus (climate scientist)

Start with the simplest possible case. Write down what Peter Kalmus (climate scientist) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth science, 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 Peter Kalmus (climate scientist) 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 Peter Kalmus (climate scientist) 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 Peter Kalmus (climate scientist)

In research
Peter Kalmus (climate scientist) appears in earth science 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 Peter Kalmus (climate scientist) 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
Peter Kalmus (climate scientist) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1974 births, 21st-century American physicists, American climatologists, so understanding it makes those chapters shorter.
In everyday life
Look for Peter Kalmus (climate scientist) 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.
