The announcement of a new purported clean source of energy came at a crucial time: adults still remembered the 1973 oil crisis and the problems caused by oil dependence, anthropogenic global warming was starting to become notorious, the anti-nuclear movement was labeling nuclear power plants as dangerous and getting them closed, people had in mind the consequences of strip mining, acid rain, the greenhouse effect and the Exxon Valdez oil spill, which happened the day after the announcement.
Singers's opinions conflict with the scientific consensus on climate change, where there is overwhelming consensus for anthropogenic global warming, and a decisive link between carbon dioxide concentration and global average temperatures, as well as consensus that such a change to the climate will have dangerous consequences.
He wrote: "This negative correlation contradicts the results of the models that IPCC relies on and indicates that anthropogenic global warming (AGW) is quite small," concluding "and now it turns out that global warming might have been 'man made' after all."
Among opponents of the mainstream scientific assessment, some say that while there is agreement that humans do have an effect on climate, there is no universal agreement about the quantitative magnitude of anthropogenic global warming (AGW) relative to natural forcings and its harm-to-benefit ratio.
The authors found that 3974 of the abstracts expressed a position on anthropogenic global warming, and that 97% of those endorsed the consensus that humans are causing global warming.
Burning hydrocarbons as fuel, producing carbon dioxide and water, is a major contributor to anthropogenic global warming.
However, the hydrochlorofluorocarbons, or HCFCs, and hydrofluorocarbons, or HFCs, are now thought to contribute to anthropogenic global warming.
The severity of this cooling in Alan Robock's model suggests that the cumulative products of 100 of these firestorms could cool the global climate by approximately 1 °C (1.8 °F), largely eliminating the magnitude of anthropogenic global warming for the next roughly two or three years.
Arctic methane emissions indirectly caused by anthropogenic global warming also affect the carbon cycle and contribute to further warming in what is known as climate change feedback.
In this sense, the term climate change has become synonymous with anthropogenic global warming.
For instance, we are now in a period of anthropogenic global warming.
Richard Cowper's three-volume novel The White Bird of Kinship (1978–82) envisions a future in which anthropogenic global warming has led to a catastrophic rise in sea level.
The issue of anthropogenic global warming presents an overwhelming example of a 'tragedy of the commons'-type of ecological market failure: The Earth's atmosphere may be regarded as a 'global common' exhibiting poorly defined (non-existing) property rights, and the waste absorption capacity of the atmosphere with regard to carbon dioxide is presently being heavily overloaded by a large volume of emissions from the world economy.
As president of the RSA, Prince Philip's first choice of speaker was Ian Plimer, professor of mineral geology at Adelaide University, but this was rejected as too controversial, as Plimer argues that the theory of Anthropogenic Global Warming is unproven.
He was critical of the BBC for giving too much space and credence to maverick views on science, including deniers of anthropogenic global warming.
To empirically link this to anthropogenic global warming is speculative.
In 2008, Cockburn wrote A Short History of Fear in which he went after the subject of anthropogenic global warming and later writing in Spiked that "you can account for the current warming by a number of well-known factors - to do with the elliptical course of the Earth in its relationship to the sun, the axis of the Earth in the current period, and possibly the influence of solar flares."
A 2010 study seemed to show lawn care inputs were balanced by the carbon sequestration benefits of lawns, and they may not be contributors to anthropogenic global warming.
Given the potential threat to marine ecosystems and its ensuing impact on human society and economy, especially as it acts in conjunction with anthropogenic global warming, there is an urgent need for immediate action."
A 2012 analysis of published research on global warming and climate change between 1991 and 2012 found that of the 13,950 articles in peer-reviewed journals, only 24 rejected anthropogenic global warming.
