Scientific consensus

Several studies of the consensus have been undertaken.[1] Among the most-cited is a 2013 study of nearly 12,000 abstracts of peer-reviewed papers on climate science published since 1990, of which just over 4,000 papers expressed an opinion on the cause of recent global warming. Of these, 97% agree, explicitly or implicitly, that global warming is happening and is human-caused.[2][3] It is "extremely likely"[4] that this warming arises from "human activities, especially emissions of greenhouse gases"[4] in the atmosphere.[5] Natural change alone would have had a slight cooling effect rather than a warming effect.[6][7][8][9]

This scientific opinion is expressed in synthesis reports, by scientific bodies of national or international standing, and by surveys of opinion among climate scientists. Individual scientists, universities, and laboratories contribute to the overall scientific opinion via their peer-reviewed publications, and the areas of collective agreement and relative certainty are summarised in these respected reports and surveys.[10] The IPCC's Fifth Assessment Report (AR5) was completed in 2014.[11] Its conclusions are summarized below:

"Warming of the climate system is unequivocal, and since the 1950s, many of the observed changes are unprecedented over decades to millennia."[12]
"Atmospheric concentrations of carbon dioxide, methane, and nitrous oxide have increased to levels unprecedented in at least the last 800,000 years."[13]
Human influence on the climate system is clear.[14] It is extremely likely (95-100% probability)[15] that human influence was the dominant cause of global warming between 1951-2010.[14]
"Increasing magnitudes of [global] warming increase the likelihood of severe, pervasive, and irreversible impacts."[16]
"A first step towards adaptation to future climate change is reducing vulnerability and exposure to present climate variability."[17]
"The overall risks of climate change impacts can be reduced by limiting the rate and magnitude of climate change"[16]
Without new policies to mitigate climate change, projections suggest an increase in global mean temperature in 2100 of 3.7 to 4.8 °C, relative to pre-industrial levels (median values; the range is 2.5 to 7.8 °C including climate uncertainty).[18]
The current trajectory of global greenhouse gas emissions is not consistent with limiting global warming to below 1.5 or 2°C, relative to pre-industrial levels.[19] Pledges made as part of the Cancún Agreements are broadly consistent with cost-effective scenarios that give a "likely" chance (66–100% probability) of limiting global warming (in 2100) to below 3 °C, relative to pre-industrial levels.[20]
National and international science academies and scientific societies have assessed current scientific opinion on global warming. These assessments are generally consistent with the conclusions of the Intergovernmental Panel on Climate Change.

Some scientific bodies have recommended specific policies to governments, and science can play a role in informing an effective response to climate change. Policy decisions, however, may require value judgements and so are not included in the scientific opinion.[21][22]

No scientific body of national or international standing maintains a formal opinion dissenting from any of these main points. The last national or international scientific body to drop dissent was the American Association of Petroleum Geologists,[23] which in 2007[24] updated its statement to its current non-committal position.[25] Some other organizations, primarily those focusing on geology, also hold non-committal positions.

This seems to conclude that greenhouse gas emissions do indeed correlate with atmospheric concentrations of carbon dioxide, methane, and nitrous oxide.
