The first serious research conducted on the effect of changes in CO2 levels was in 1896, when Arrhenius completed a laborious numerical computation which suggested that cutting the amount of CO2 in the atmosphere by half could lower the temperature in Europe some 4-5°C (roughly 7-9°F) - that is, to an ice age level. Arrhenius made a calculation for doubling the CO2 in the atmosphere, and estimated it would raise the Earth's temperature some 5-6°C (averaged over all zones of latitude). Arrhenius did not see that as a problem. He figured that if industry continued to burn fuel at the current (1896) rate, it would take perhaps three thousand years for the CO2 level to rise so high. In any case Arrhenius and other researchers were only interested in explaining the Ice Ages. No one seriously believed that global warming was coming. After much criticism, the work of Arrhenius was ignored by the scientific community.
In 1931, an American physicist, E.O. Hulburt, produced calculations supported Arrhenius's estimate that doubling or halving CO2 would bring something like a 4°C rise or fall of surface temperature, but he was a relatively uknown scientist and published his work in a little known Journal.
In 1938 an English engineer, Guy Stewart Callendar, compiled measurements of temperatures from the nineteenth century onwards and confirmed that there was a warming trend. He went on to evaluate old measurements of atmospheric carbon dioxide concentrations and concluded that over the previous hundred years the concentration of the gas had increased by about 10 per cent. Callendar asserted that this could explain the observed warming.
Scientists first began to study greenhouse gases in the 19th century, with the first mention of the greenhouse effect attributed to the French mathematician Joseph Fourier in the 1820s. Swedish scientist Svante Arrhenius made significant contributions to the understanding of how carbon dioxide in the atmosphere could affect the Earth's climate in the late 19th century.

Which gas is known as the third greenhouse gas?
Nitrous oxide is known as the third greenhouse gas, after carbon dioxide and methane. It is a potent greenhouse gas that is produced through agricultural activities, industrial processes, and combustion of fossil fuels.
What is a greenhouse gas containing only hydrogen and oxygen?
Water vapor (H2O) is a greenhouse gas that contains only hydrogen and oxygen. It is a natural component of the Earth's atmosphere and contributes to the greenhouse effect.
Is ammonia NH3 a greenhouse gas?
Yes, ammonia (NH3) is considered a greenhouse gas. While it is less potent than gases like carbon dioxide or methane, it can still contribute to the greenhouse effect and global warming when present in the atmosphere.
Many scientists believe the greenhouses gases?
Many scientists believe that greenhouse gases, such as carbon dioxide and methane, contribute to the warming of the Earth's atmosphere by trapping heat from the sun. This phenomenon is commonly referred to as the greenhouse effect and is a major driver of climate change. Efforts to reduce greenhouse gas emissions are crucial in mitigating the impacts of global warming.
Is a greenhouse gas that traps heat in the atmosphere?
Carbon dioxide is a greenhouse gas that traps heat in the atmosphere.
When was greenhouse gas first discovered?
The concept of greenhouse gases was first discovered in the early 19th century by scientists like Joseph Fourier and John Tyndall. They found that certain gases in the atmosphere, like carbon dioxide and water vapor, trap heat and contribute to the greenhouse effect.
What greenhouse gas do scientists believe has increased due to pollution?
Carbon dioxide, from the burning of coal, oil and natural gas, the fossil fuels.
Are scientist sure that the greenhouse effect causes warming of air?
Yes, scientists are confident that the greenhouse effect causes warming of the Earth's atmosphere. This has been thoroughly researched and supported by data showing the increase in greenhouse gas concentrations and global temperatures over the past century. The greenhouse effect is a natural process, but human activities have enhanced it by releasing additional greenhouse gases into the atmosphere.
Why are studies of volcanoes helpful to scientists who wish to understand the greenhouse effect?
Volcanoes, like the burning of fossil fuels, are also a source of the primary greenhouse gas, carbon dioxide.
Why are scientists worried about the thaw in Siberia?
Scientists are concerned because the thaw in Siberia will release methane from the melting tundra. Methane is a powerful greenhouse gas which is contributing to global warming.
Which country launched the world's first satellite for monitoring greenhouse gas?
japan
Is Greenhouse gas a noun?
Yes, "greenhouse gas" is a noun referring to gases that trap heat in the Earth's atmosphere, contributing to the greenhouse effect and global warming.
Which gas is known as the third greenhouse gas?
Nitrous oxide is known as the third greenhouse gas, after carbon dioxide and methane. It is a potent greenhouse gas that is produced through agricultural activities, industrial processes, and combustion of fossil fuels.
Is ozone a greenhouse gas?
Yes, ozone is considered a greenhouse gas. While ozone in the stratosphere protects us from the sun's harmful ultraviolet radiation, at ground level it can contribute to warming the Earth's surface as a greenhouse gas.
What is the name of the greenhouse gas which destroys another greenhouse gas?
CFCs (chlorofluorocarbons) destroy ozone.
How do scientists know that there is more carbon dioxide and other greenhouse gases in the air than there was thousands of years ago?
Scientists analyze ice cores, tree rings, and other natural records that trap air from thousands of years ago to measure historical levels of greenhouse gases like carbon dioxide. By comparing these data with current atmospheric measurements, scientists can determine that greenhouse gas concentrations have increased significantly over time.
Why are scientists trying to find alternative energy sources now?
Scientists are trying to find alternative energy sources to reduce our dependence on fossil fuels, which contribute to climate change. By using cleaner, renewable energy sources like solar, wind, and hydroelectric power, we can help reduce greenhouse gas emissions and create a more sustainable energy future.
