How Did The Public Accept Greenhouse Gas Emissions?

The greenhouse effect, a concept proposed by ancient Greeks, involves the accumulation of certain gases in Earth’s atmosphere, including carbon dioxide. These gases have far-ranging environmental and health effects, such as climate change by trapping heat and contributing to respiratory disease from smog and air pollution. The greenhouse effect occurs when certain gases accumulate in Earth’s atmosphere, such as carbon dioxide.

Global CO2 emissions from human activities are now higher than at any point in history, with recent data showing that global CO2 emissions were 182. Greenhouse gases vary in their sources, measures needed to control them, intensity of solar heat trapping, duration of presence in the atmosphere, and how they cause warming. For over a century, scientists have understood the basic physics behind greenhouse gases like carbon dioxide, which make up just a small fraction of the global greenhouse gas emissions.

From 1850 to the mid-20th century, the world experienced near-constant growth in emissions due largely to industrialization and burning fossil fuels, cutting down forests, and farming livestock. In 2010, the burning of coal, natural gas, and oil for electricity and heat was the largest single source of global greenhouse gas emissions (25%). The majority of carbon dioxide emissions by humans come from the burning of fossil fuels, with remaining contributions from agriculture and industry.

The greenhouse effect is essential to life on Earth, but human-made emissions in the atmosphere are trapping and slowing heat loss to space. Water vapor was seen as a more influential greenhouse gas in the 1940s. In 2022, fossil fuel combustion was the source of about 74% of total U.S. human-caused greenhouse gas emissions. The world needs to decarbonize to reduce human emissions of greenhouse gases and combat climate change.

Who caused the most greenhouse gases?

Since the advent of the Industrial Revolution, there has been a notable increase in carbon dioxide emissions, predominantly resulting from the combustion of fossil fuels. The three countries with the highest levels of emissions are China, the United States, and the European Union. When emissions per capita are considered, the United States and Russia have the highest rates. The majority of global greenhouse gas emissions are attributable to a relatively limited number of countries.

Why did the term greenhouse effect stick in the public imagination?

The greenhouse effect, a term coined by Joseph Fourier, is a phenomenon where a greenhouse heats up due to radiation trapping in the atmosphere. This phenomenon, which began in the early 19th century, was first identified as a result of human emissions of greenhouse gases. The effect was further strengthened by Claude Pouillet in 1827 and 1838. Eunice Newton Foote in 1856 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 largely due to water vapor, with small percentages of hydrocarbons and carbon dioxide having a significant effect. Svante Arrhenius in 1896 made the first quantitative prediction of global warming due to a hypothetical doubling of atmospheric carbon dioxide.

In the 1960s, the evidence for the warming effect of carbon dioxide gas became increasingly convincing. Scientists also discovered that human activities that generate atmospheric aerosols could have cooling effects, later known 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.

When did environmentalism become mainstream?

Starting in the 1960s, environmentalism was given political expression through the establishment of “green” political movements, including activist nongovernmental organizations and environmentalist political parties. The movement aimed to protect the environment, promote grassroots democracy, social justice, and nonviolence. However, some environmental groups and activists saw violence as a justifiable response to the violent treatment of nature by certain interests, such as logging and mining industries.

In the industrialized West, the contemporary green movement focused on changing government policy and promoting environmental social values. Examples include campaigns in Tasmania to block flooding and damming of Lake Pedder, protests against nuclear power development, deforestation in Indonesia and the Amazon basin, and campaigns to limit greenhouse gas emissions. In the less-industrialized or developing world, environmentalism has been more involved in “emancipatory” politics and grassroots activism on issues such as poverty, democratization, and political and human rights, including the rights of women and indigenous peoples.

The early strategies of the contemporary environmental movement were self-consciously activist and unconventional, involving direct-protest actions, public-education and media campaigns, community-directed activities, and lobbying of policy makers and political representatives. The movement also attempted to set public examples to increase awareness and sensitivity to environmental issues, such as recycling, green consumerism, and the establishment of alternative communities.

Electoral strategies included the nomination of environmental candidates and the registration of green political parties, which aimed to bring the influence of the grassroots environmental movement directly to the machinery of government, make the environment a central concern of public policy, and render state institutions more democratic, transparent, and accountable. Green parties have been formed in the former Soviet bloc, the former Soviet bloc, and some developing countries in Asia, South America, and Africa, though they have achieved little electoral success there.

Who popularized the term global warming?

In 1975, US scientist Wallace Broecker introduced the term “global warming” in a scientific paper. The Montreal Protocol, established in 1987, restricted the use of chemicals that were damaging the ozone layer, which had a greater impact on greenhouse gas emissions than the Kyoto Protocol. In 1988, the Intergovernmental Panel on Climate Change (IPCC) was established with the objective of assessing the evidence pertaining to climate change.

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.

When did climate change become mainstream?

In 1988, global warming and the depletion of the ozone layer became increasingly prominent in the international public debate and political agenda. The United Nations Environment Programme (UNEP) organized an internal seminar to identify environmental sectors sensitive to climate change, and the Intergovernmental Panel on Climate Change (IPCC) was established to examine greenhouse warming and global climate change.

The General Assembly identified climate change as a specific and urgent issue, asking the World Meteorological Organization (WMO) and UNEP to initiate a comprehensive review and make recommendations on climate change.

In 1989, the first significant global efforts were taken, with the Maldives transmitting the text of the Malé Declaration on Global Warming and Sea Level Rise to the UN Secretary-General, the Helsinki Declaration on the Protection of the Ozone Layer being adopted, and the Montreal Protocol on Substances that Deplete the Ozone Layer entering into force. The second World Climate Conference, held from 29 October to 7 November 1990, further advanced efforts to raise awareness of the effects of climate changes.

The United Nations Conference on Environment and Development convened in 1992 in Rio de Janeiro, Brazil, which set a new framework for seeking international agreements to protect the integrity of the global environment. Chapter 9 of Agenda 21 dealt with the protection of the atmosphere, establishing the link between science, sustainable development, energy development and consumption, transportation, industrial development, stratospheric ozone depletion, and transboundary atmospheric pollution.

The most significant event during the Conference was the opening for signature of the United Nations Framework Convention on Climate Change (UNFCCC), which stabilized atmospheric concentrations of “greenhouse gases” to prevent dangerous anthropogenic interference with the climate system. The Kyoto Protocol, adopted in Japan in December 1997, aimed to reduce industrialized countries’ emissions of carbon dioxide and other greenhouse gases by at least 5% below 1990 levels in the commitment period of 2008 to 2012.

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.

When did scientists start warning about climate change?

Scientists began to worry about climate change in the late 1950s, with the scientific community uniting in the 1980s to take action. However, the concern for climate change dates back thousands of years, with debates about the impact of human activities on the environment dating back to ancient Greece. As early as 1200 B. C. to A. D. 323, people debated whether draining swamps or cutting down forests might bring more or less rainfall to the region. The scientific community’s interest in how our activities affect the climate has only escalated since then, but the melting iceberg is just the tip of the melting iceberg.

When was the greenhouse effect first noticed?

The greenhouse effect, which affects Earth’s temperature, has been a scientific concept for almost 200 years. John Tyndall discovered carbon dioxide as a greenhouse gas in 1859, indicating its ability to absorb and hold heat. Svante Arrhenius, a Swedish scientist, claimed that burning fossil fuels would release carbon dioxide into the atmosphere, eventually warming the planet. His predictions were accurate, and Guy Callendar, in 1938, made the first actual linkage between rising carbon dioxide levels and the Earth’s temperature increase.

Why did greenhouse gases start?

The combustion of fossil fuels, such as coal and oil, has resulted in an increase in greenhouse gas concentrations due to the process of carbon-oxygen combustion in the atmosphere.

Who came up with global warming?

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.
