Why Do Scientists Use AI?
The short answer is:
We’ve conducted case studies on the use of AI in a wide variety of environments, including everything from the dynamics of nonlinear chaotic systems to songwriting and musical production.
All produced similar results—benefits to the environment, the economy, and society.
For instance, the climate education and graphics used for this post are based on this scientific paper as well as the publicly accessible version.
If I had created them manually, the costs in time, labor, energy, and resources would have been substantial. Using AI, the direct dollar cost to me was effectively zero, the graphics were generated in about a minute, and the estimated natural-resource cost was roughly $0.067 per image.
By comparison, producing similar graphics through traditional methods could easily have cost hundreds of dollars when accounting for labor, software, revisions, and associated natural-resource use. Mathematically, the AI-generated version required approximately 0.005% of those resources—just five thousandths of one percent of the traditional cost. These savings are equivalent to a reduction in environmental impact.
The benefits—in both environmental savings to the planet through reduced physical-resource use and in the ability to produce and distribute education—far outweigh the costs.
Most importantly:
The only effective way to stop the acceleration of climate change is through the reduction of fossil-fuel combustion.
However, the most likely way of reversing the trajectory of climate change is through people using AI to develop previously unthought-of methods and technologies that can fundamentally change how we produce, consume, and manage resources—and potentially remove greenhouse gases from the atmosphere.
Anti-Science and Technology Rhetoric
Unfortunately, the lack of science and technology literacy is at the root of many of society’s problems. Anti-AI opinions can sometimes resemble the anti-science rhetoric used by climate-change deniers, particularly when conclusions are formed before the underlying evidence or technology has been examined.
Research in cognitive and political psychology suggests that rejection of scientific evidence is more complicated than simply a lack of intelligence or education. People can engage in motivated reasoning—evaluating evidence in ways that protect existing political, ideological, or cultural identities. When scientific findings conflict with strongly held beliefs, individuals may scrutinize contradictory evidence more critically, accept supporting evidence with less scrutiny, or reinterpret information so that it remains compatible with their existing worldview. This phenomenon has been documented across a range of politically contested scientific issues, including climate change. (Kahan, 2017; Borghi et al., 2026.)
Importantly, this does not mean that people who reject scientific evidence necessarily lack intelligence or analytical ability. Some research has found that greater reasoning ability can actually strengthen politically motivated reasoning when individuals use that ability to construct arguments supporting conclusions they are already motivated to accept.
Conspiracy beliefs provide another example. A review of the literature found that conspiracy belief is generally associated with greater reliance on intuition and less reflective reasoning. Other preregistered research has found that endorsement of particularly implausible conspiracy theories can be associated with reduced information sampling and less reflective reasoning. (Binnendyk & Pennycook, 2022; Hattersley et al., 2022.)
The same general principles apply to public opinions about technology. Someone who has never used AI as a scientific research assistant is evaluating the technology from a fundamentally different position than a scientist who has spent years developing, testing, and refining specialized AI systems for research. An opinion formed without direct experience may therefore reflect assumptions about what AI is rather than knowledge of what AI can actually do.
Scientists increasingly use AI as a specialized research tool. AI is artificial SUPPLEMENTAL intelligence. It is not necessarily a replacement for the scientist. Instead, it can function as an extension of the researcher’s computational, analytical, and creative capabilities—particularly when the system has been deliberately trained or configured for a specific scientific task.
Science communication research also suggests that curiosity and willingness to engage with information can matter. Kahan found that science curiosity was associated with more open-minded engagement with information that conflicted with a person’s political predispositions. In other words, the ability to consider information that challenges one’s existing beliefs may be at least as important as simply possessing scientific knowledge. (Kahan, 2017.)
In my case, I have spent years developing multiple specially trained “lab assistants” that have learned from scores of our own work. When Sidd and I started, our work had to be done on Ohio State computers and supercomputers that Sidd helped create. Things like “a floating decimal” were, and still are, a significant problem. Problems that needed solving would take months or years to process. The amount of energy spent on computation was enormous compared with today.
Things have changed for the better.
This year, we were able to establish third-derivative behavior across multiple climate indicators—extremely important developments in climate science that confirm that the acceleration rate of climate change is itself accelerating. This work was completed within four months. Historically, I would have been unlikely to complete this work in my lifetime if it were not for AI.
The broader lesson is that scientific progress depends not only on the ability to acquire information but also on the willingness to investigate unfamiliar methods and revise established assumptions. Research on science denial emphasizes that rejection of expert conclusions cannot be explained simply by ignorance or irrationality. Trust, identity, perceived competence, political conflict, and the social cues people use to determine whom to believe can all influence whether scientific evidence is accepted. (Lewandowsky et al., 2022; Sinatra et al., 2019.)
In the meantime, the United States has gone extremist in anti-science and anti-technology ideology, much to the detriment of science and scientists in the U.S. In fact, we are now working on bringing up our own AI computer using Chinese technology. It will be running on DeepSeek. The single computer will do the work of what used to take at least a dozen servers to accomplish, at a fraction of the price. It will not be run in a data center. It will not be costing society anything. In fact, it will be greatly benefiting society and helping to solve the climate crisis.
The distinction is therefore important: criticizing a technology based on evidence, testing, or demonstrated limitations is part of science. Rejecting a technology without understanding how it works or without examining its actual applications is something very different.
So, the next time you want to voice your opinion about AI, do your homework first. Start by getting at least a master’s-level education in climate science. Then spend years training your AI assistants. After completion, I would be happy to discuss AI with you.

Deep-learning approaches have also been demonstrated for providing early warnings of rate-induced tipping in nonlinear dynamical systems.
Climate-System Data Analysis: Modern climate research produces enormous datasets from satellites, ocean observations, atmospheric measurements, weather stations, and numerical models. Machine learning can help scientists analyze these high-dimensional datasets, reconstruct missing observations, identify patterns and anomalies, and extract relationships that are difficult to identify using conventional analytical approaches alone. A 2026 Nature Communications review describes AI as increasingly capable of learning directly from vast streams of Earth observations for weather and climate prediction.
Climate Modeling: Machine learning is increasingly being used alongside conventional climate models to emulate computationally expensive processes, improve parameterizations, accelerate selected model components, and generate large ensembles of simulations. Climate-model emulators can reproduce selected outputs of complex Earth-system models at substantially lower computational cost, allowing scientists to explore more scenarios and parameter combinations than would otherwise be practical.

AI-based methods can assist in identifying candidate gravitational-wave events and distinguishing astrophysical signals from instrumental artifacts, providing another layer of analysis alongside conventional detection pipelines.
Galaxy Classification: AI systems can automatically classify galaxies according to morphology, allowing astronomers to analyze enormous survey datasets and study galaxy formation and evolution. Deep-learning systems have been demonstrated on hundreds of thousands to more than 20 million galaxies, achieving high agreement with human classifications for several morphological categories.
Detecting Astronomical Anomalies: Machine learning can search astronomical surveys for unusual objects that do not fit established classifications. For example, the Astronomaly system was applied to almost four million galaxy images from the Dark Energy Camera Legacy Survey to identify unusual sources and prioritize potentially interesting objects for further investigation.
Processing Telescope Data: Modern astronomical surveys generate enormous volumes of imaging and spectroscopic data. Machine learning is being used for automated data processing, object classification, anomaly detection, image analysis, and even real-time monitoring of telescope performance. A 2026 Annual Review of Astronomy and Astrophysics describes deep learning as a complementary analytical tool for modern astronomical surveys, including anomaly detection and automated scientific discovery.
Automated Scientific Discovery: AI is increasingly being used not simply to classify known astronomical objects, but to search for unexpected patterns, unusual sources, and previously unrecognized relationships within astronomical datasets. This includes supervised learning, unsupervised learning, anomaly detection, representation learning, and increasingly automated research workflows.
These examples span medicine, biology, materials science, physics, astronomy, energy, and climate science. The common thread is not that AI replaces scientists. It is that AI gives scientists a new computational instrument for exploring problems that were previously too large, too complex, or too time-consuming to investigate.
In many cases, AI does not eliminate the need for conventional scientific methods. Instead, it reduces the amount of computational or experimental work required to identify promising possibilities. Scientists still have to formulate questions, evaluate evidence, design experiments, validate results, and determine whether an AI-generated prediction is actually correct.
That is why we describe AI as artificial SUPPLEMENTAL intelligence: a tool that extends human scientific capabilities rather than replacing the scientist.
