quoteThe Earth’s climate is changing in response to increasing concentrations of greenhouse gases (GHGs) and particulate matter in the atmosphere, largely as the result of human activities.
quoteBased on extensive scientific evidence, it is extremely likely that human activities, especially emissions of greenhouse gases, are the dominant cause of the observed warming since the mid-20th century. There is no alterative explanation supported by convincing evidence.
quoteObservations throughout the world make it clear that climate change is occurring, and rigorous scientific research demonstrates that the greenhouse gases emitted by human activities are the primary driver.
quoteThe Geological Society of America concurs with assessments by the National Academies of Science (2005), the National Research Council (2011), the Intergovernmental Panel on Climate Change (2013), and the U.S. Global Change Research Program (2014) that global climate has warmed in response to increasing concentrations of carbon dioxide and other greenhouse gases, and that human activities are the dominant cause of the rapid warming since the middle 1900s.

referenceThe U.S. National Climate Assessment determined that human activities, principally through emissions of greenhouse gases, have unequivocally caused global warming and that severe climate risks to the United States will continue to grow without deeper cuts in global net greenhouse emissions and accelerated adaptation efforts.
referenceThe Intergovernmental Panel on Climate Change (IPCC) concluded that human activities, principally through emissions of greenhouse gases, have unequivocally caused global warming.

claimGlobal warming is defined as the increment in the temperature of the Earth's surface caused by the effect of greenhouse gases released into the atmosphere by human activities.
