Meaning: This quote by Nils-Axel Morner, a prominent geologist and climate change skeptic, reflects the traditional approach of geologists to their work. Morner is emphasizing the importance of field observation in geology and the need to ground scientific understanding in real-world evidence before turning to computer models. This quote highlights the fundamental principle of geology as a science that is rooted in direct observation of the Earth's processes and history.

Geology is the study of the Earth's structure, materials, and processes, and it encompasses a wide range of sub-disciplines, including mineralogy, petrology, geochemistry, and paleontology. Fieldwork is an essential component of geology, as it allows geologists to directly observe rock formations, landforms, and geological processes in their natural environment. By examining outcrops, collecting samples, and mapping geological features, geologists can develop a detailed understanding of the Earth's history and the processes that have shaped its surface over millions of years.

The emphasis on field observation in geology reflects the discipline's historical roots and its close connection to the natural world. Geologists have long recognized the importance of direct observation as a means of understanding geological phenomena. By carefully documenting and analyzing the characteristics of rocks, fossils, and landforms in the field, geologists can piece together the complex history of the Earth and unravel the processes that have shaped its surface.

In addition to field observation, geologists also utilize a range of analytical techniques to study geological materials and processes. These may include laboratory analysis of rock and mineral samples, geochemical studies, and the use of geophysical methods to investigate subsurface structures. However, these analytical methods are often employed in conjunction with fieldwork, as they provide valuable insights that complement and support the observations made in the field.

The quote also touches on the use of computerization and modeling in geology. While field observation remains a foundational aspect of geological research, the development of computer models has become an increasingly important tool for geologists. These models are used to simulate geological processes, interpret complex datasets, and make predictions about future geological events. However, as Morner suggests, the use of computer models should be informed by field observations and real-world data, rather than serving as the primary basis for understanding geological phenomena.

It is worth noting that Morner's views on climate change have been controversial within the scientific community, and his skepticism of mainstream climate science has been widely criticized by climate scientists. While field observation is indeed a fundamental aspect of geological research, it is important to recognize that the use of computer models and other analytical tools has also become integral to the advancement of the discipline. The integration of fieldwork, laboratory analysis, and computer modeling allows geologists to develop comprehensive and nuanced understandings of geological processes and phenomena.

In conclusion, Nils-Axel Morner's quote highlights the central role of field observation in geology and emphasizes the importance of grounding scientific understanding in direct, real-world evidence. Fieldwork remains a fundamental aspect of geological research, allowing geologists to directly observe and document the Earth's processes and history. While the use of computer models and analytical techniques has become increasingly important in geology, they should be informed by and complemented by field observations. This approach reflects the traditional principles of geology as a science that is deeply rooted in the natural world and the physical processes that shape it.
