			== History of Climate Science ==

			=== Early Greenhouse-Effect Discoveries ===

			The history of climate science began with efforts to understand why Earth is warmer than it would be from sunlight alone. Joseph Fourier argued in the early nineteenth century that the atmosphere helps regulate planetary temperature. Eunice Foote later demonstrated that carbon dioxide absorbs heat, and John Tyndall showed experimentally that water vapor, carbon dioxide, and other gases absorb infrared radiation. These discoveries created the physical foundation for the greenhouse effect.

			Svante Arrhenius advanced the field in 1896 by calculating how changes in atmospheric carbon dioxide could alter global temperature. Although early climate research also included theories of ice ages, solar variation, and geological change, greenhouse-gas research gradually became central to understanding human influence on climate.

			=== Carbon Dioxide and the Rise of Modern Climate Research ===

			Twentieth-century scientists revived and strengthened the carbon dioxide theory of climate change. G. S. Callendar argued in 1938 that industrial carbon dioxide emissions were already warming the planet. Gilbert Plass later used radiation calculations to show that fossil-fuel emissions could increase global temperature. Roger Revelle and Hans Suess helped establish that the ocean would not immediately absorb all human-produced carbon dioxide, making atmospheric accumulation a serious issue.

			Charles David Keeling’s continuous carbon dioxide measurements at Mauna Loa became one of the most important records in climate science. The Keeling Curve showed a steady rise in atmospheric carbon dioxide, transforming climate change from a theoretical concern into an observable global trend.

			=== Paleoclimate, Ice Ages, and Climate Archives ===

			Climate science also developed through the study of Earth’s distant past. Researchers used fossil shells, ice cores, tree rings, marine sediments, cave formations, and other proxy records to reconstruct past climates. These records showed that Earth’s climate has changed dramatically over thousands to millions of years.

			Studies of ice ages, orbital cycles, and greenhouse-gas feedbacks helped scientists understand natural climate variation. Paleoclimate evidence also revealed that climate can shift abruptly, challenging older assumptions that climate change always occurs slowly. Ice-core records, including the Vostok record, became especially important because they preserved ancient air bubbles and showed relationships among temperature, carbon dioxide, methane, and glacial cycles.

			=== Climate Models, Satellites, and Global Data ===

			Modern climate science depends heavily on computer models, global observations, and satellite data. Early radiation calculations and simple climate models evolved into general circulation models that simulate the atmosphere, oceans, land, ice, and biosphere. Researchers used these models to test explanations of past climate change and project future warming.

			Satellites transformed climate science by allowing scientists to monitor Earth as a connected system. NASA, NOAA, and international programs developed tools to measure temperature, radiation, clouds, aerosols, sea ice, land change, ocean conditions, and greenhouse gases. Programs such as Landsat, CERES, AIRS, GRACE, and Earth Observing System missions helped expand climate science beyond local measurements into global Earth system science.

			=== Evidence of Modern Climate Change ===

			Multiple lines of evidence show that Earth’s climate is warming. Scientists track rising atmospheric carbon dioxide, increasing global temperatures, ocean heat content, melting glaciers, shrinking Arctic sea ice, rising sea levels, and changes in ecosystems. Ocean warming and sea-level rise became especially important indicators because they show the long-term accumulation of heat in the climate system.

			Research also examined possible natural causes such as solar variation, volcanic eruptions, aerosols, and internal climate variability. Over time, the evidence showed that recent warming cannot be explained by natural factors alone and is primarily driven by human greenhouse-gas emissions.

			=== Scientific Assessments and Consensus ===

			Climate science became increasingly organized through national and international institutions. The World Meteorological Organization, World Climate Research Programme, U.S. Global Change Research Program, National Academy of Sciences, and Intergovernmental Panel on Climate Change helped coordinate research and publish major assessments.

			The 1979 Charney Report helped establish that rising carbon dioxide would cause significant warming. Later IPCC reports strengthened the scientific conclusion that human activities are warming the atmosphere, ocean, and land. By the late twentieth and early twenty-first centuries, climate science had developed a strong consensus that global warming is real, primarily human-caused, and supported by many independent lines of evidence.

			=== Public Debate, Policy, and Climate Attribution ===

			Climate science gradually moved from specialized research into public debate and government policy. Reports in the 1960s and 1970s warned that fossil-fuel emissions could alter climate. James Hansen’s 1988 congressional testimony became a major public moment, helping bring global warming into mainstream political discussion.

			The field also expanded to study impacts, including sea-level rise, drought, storms, agriculture, ecosystems, health, and extreme weather. Climate attribution science developed to estimate how human-caused warming affects the likelihood and intensity of specific events. At the same time, public understanding was shaped by media coverage, environmental politics, industry opposition, and debates over regulation, carbon offsets, geoengineering, and international climate targets.

			=== Conclusion ===

			The history of climate science is the story of how many fields—physics, chemistry, geology, meteorology, oceanography, biology, computer modeling, and public policy—came together to explain Earth’s changing climate. From early experiments on heat-trapping gases to the Keeling Curve, ice-core records, global climate models, satellite observations, and IPCC assessments, scientists built a detailed understanding of greenhouse warming. The evidence now shows that human activity has changed the climate system, making climate science one of the most important scientific and policy fields of the modern era.
