There is a nearly unanimous scientific consensus that the Earth has been consistently warming since the start of the Industrial Revolution, that the rate of recent warming is largely unprecedented,[1]: 8 [2]: 11 and that this warming is mainly the result of a rapid increase in atmospheric carbon dioxide (CO2) caused by human activities. The human activities causing this warming include fossil fuel combustion, cement production, and land use changes such as deforestation,[3]: 10–11 with a significant supporting role from the other greenhouse gases such as methane and nitrous oxide.[1]: 7 This human role in climate change is considered "unequivocal" and "incontrovertible".[1]: 4 [2]: 4
Nearly all actively publishing climate scientists say humans are causing climate change.[4][5] Surveys of the scientific literature are another way to measure scientific consensus. A 2019 review of scientific papers found the consensus on the cause of climate change to be at 100%,[6] and a 2021 study concluded that over 99% of scientific papers agree on the human cause of climate change.[7] The small percentage of papers that disagreed with the consensus often contained errors or could not be replicated.[8]
The evidence for global warming due to human influence has been recognized by the national science academies of all the major industrialized countries.[9] In the scientific literature, there is a very strong consensus that global surface temperatures have increased in recent decades and that the trend is caused by human-induced emissions of greenhouse gases.[10] No scientific body of national or international standing disagrees with this view.[11] A few organizations with members in extractive industries hold non-committal positions,[12] and some have tried to persuade the public that climate change is not happening, or if the climate is changing it is not because of human influence,[13][14] attempting to sow doubt in the scientific consensus.[15]

It is likely that most of the warming in recent decades can be attributed to human activities (IPCC 2001). This warming has already led to changes in the Earth's climate.
