When Did The Greenhouse Effect Become Known To Scientists?

In 1896, Swedish scientist Svante Arrhenius became the first person to imagine that humanity could change the climate on a global scale. Joseph Fourier first suggested that gases in the atmosphere trap some of the sun’s heat like glass in a greenhouse, leading to the concept of the greenhouse effect. In 1856, American woman Eunice Newton Foote demonstrated the greenhouse effect in her home laboratory by placing a glass cylinder full of carbon dioxide in her home laboratory.

Scientists have understood the basic physics behind why greenhouse gases cause warming for over a century. The existence of the greenhouse effect was proposed as early as 1824 by Joseph Fourier. In recent years, it has become apparent that an American woman, Eunice Foote, made a similar discovery in 1856, three years before Tyndall. Charles David Keeling, a young postgraduate geochemist, decided to compare the amounts of CO2 in water and air in 1958.

Svante Arrhenius was the first to claim in 1896 that fossil fuel combustion may eventually result in enhanced global warming. NASA climate scientist James Hansen testified before the Senate Energy and Natural Resources Committee in 1988, stating that climate was warming due to greenhouse gases. In the 1860s, physicist John Tyndall recognized Earth’s natural greenhouse effect and suggested that slight changes in atmospheric composition could bring about climate change. Alexander Graham Bell described the greenhouse effect and the possibility of global warming in 1917, while Guy Stewart Callendar demonstrated in the 19th century that gases in the atmosphere cause a “greenhouse effect” that affects the planet’s temperature.

When did we first notice the Earth’s greenhouse effect?

In 1896, Swedish scientist Svante Arrhenius posited that atmospheric carbon dioxide levels could significantly alter surface temperature through the greenhouse effect. This hypothesis was subsequently expanded upon by Guy Callendar in 1938, who linked it to the phenomenon of global warming.

Which scientist told the theory of greenhouse effect?

In 1859, Irish physicist John Tyndall discovered the absorption of heat by gases, a groundbreaking discovery that set the foundation for our modern understanding of climate change, meteorology, and weather. Tyndall’s apparatus, which he had set up at the Royal Institution in London, allowed him to detect the absorption of heat by gases, including carbon dioxide and water vapor. This discovery laid the groundwork for our modern understanding of the greenhouse effect and its impact on climate change.

Did global warming begin earlier than we thought?

A new study published in Nature reveals that warming in some regions began as early as the 1830s, much earlier than previously thought. This discovery redefines our understanding of when human activity began to influence our climate. Determining when global warming began and how quickly the planet has warmed is essential for understanding how much we have altered the climate in different parts of the world. The study helps answer the question of whether our climate is operating outside safe thresholds for human society and functional ecosystems.

How long have scientists know about climate change?

The scientific discovery of climate change began in the early 19th century when ice ages and other natural changes in paleoclimate were first suspected. The natural greenhouse effect was first identified in 1824 by Joseph Fourier, and further strengthened by Claude Pouillet in 1827 and 1838. Eunice Newton Foote demonstrated that the sun’s warming effect is greater for air with water vapor than for dry air, and even greater with carbon dioxide.

John Tyndall measured the infrared absorption and emission of various gases and vapors, showing that the effect was due to a small proportion of the atmosphere, largely due to water vapor. Svante Arrhenius made the first quantitative prediction of global warming due to a hypothetical doubling of atmospheric carbon dioxide in 1896.

In the 1960s, evidence for the warming effect of carbon dioxide gas became increasingly convincing, and scientists discovered that human activities that generated atmospheric aerosols could have cooling effects, later referred to as global dimming. Other theories for the causes of global warming were also proposed, involving forces from volcanism and solar variation. The scientific understanding of global warming greatly increased during the 1970s.

Are there any scientists who disagree with global warming?

The majority of climate scientists, including 97% of those with active publications, concur that human activity is the primary driver of global warming and climate change. Leading scientific organizations, including international and U. S. science academies, the United Nations Intergovernmental Panel on Climate Change, and other reputable bodies, have issued public statements expressing this position.

Who discovered the greenhouse effect in 1824?

The greenhouse effect, first proposed by Joseph Fourier in 1824, was further strengthened by Claude Pouillet in 1827 and 1838. Eunice Newton Foote demonstrated that the sun’s warming effect is greater for air with water vapor than dry air, and even greater with carbon dioxide. The term “greenhouse” was first applied to this phenomenon by Nils Gustaf Ekholm in 1901. The greenhouse effect on Earth is defined as the infrared radiative effect of all infrared absorbing constituents in the atmosphere, including greenhouse gases (GHGs), clouds, and some aerosols. The enhanced greenhouse effect is due to human action increasing the concentration of GHGs in the atmosphere, resulting in a more significant natural greenhouse effect.

When did scientists start warning about global warming?

Since the 1970s, politicians, economists, and scientists have been aware of climate change, with the New York Times revealing its existence in February 1977. The top leaders of countries were aware of the warnings, sharing this knowledge with the governments of major industrial powers. Scientific studies at the time indicated that human activity, particularly carbon dioxide and methane emissions, were causing the greenhouse effect, which had socioeconomic and political consequences. The text did not mention the greenhouse effect produced by fuel burning.

Who first predicted the greenhouse effect?

Svante Arrhenius, a Swedish scientist, was the first to propose that the greenhouse effect, a phenomenon resulting from the presence of certain gases in the atmosphere, could affect the Earth’s climate. In 1896, he claimed that the combustion of fossil fuels could lead to global warming. Arrhenius proposed that atmospheric carbon dioxide could cause temperature changes on Earth, which he discovered was due to the absorption and re-emission of infrared radiation from water vapor and carbon dioxide.

He presented his findings in a paper titled “On the Influence of Carbonic Acid in the Air upon the Temperature of the Ground”, which led to his investigation into the impact of increasing atmospheric levels of carbon dioxide on Earth’s climate and temperature. Arrhenius also proposed that doubling the amount of carbon dioxide in the atmosphere would raise Earth’s temperature by 5°C, which aligns with modern predictions. However, he was incorrect in estimating the timescale for achieving this doubling, estimating a time scale of 3000 years.

Who was the first person to experiment scientifically about the greenhouse effect?

Today’s Google doodle focuses on Eunice Newton Foote, who discovered the greenhouse effect and played a significant role in women’s rights movements. Foote’s work, which is often attributed to physicist John Tyndall, involved experiments on how heat affected air. In 2011, amateur historian Raymond Sorenson discovered a record of Foote’s work at the American Association for the Advancement of Science in 1856, which is the first record of a physics article by a female scientist. Foote concluded that the highest effect of the sun’s rays was found in carbonic acid gas, primarily carbon dioxide, and speculated that an atmosphere of that gas would give Earth a high temperature.

When did we first become aware of climate change?

In 1938, steam engineer Callendar collected records from 147 weather stations worldwide and found that global temperatures had risen 0. 3°C over the past 50 years. He argued that carbon dioxide emissions from industry were responsible for global warming. Despite his crude methods, Callendar’s estimates of global warming were highly accurate and in line with modern assessments, indicating that humans could significantly impact the climate.
