The AR5 concluded that human influence on the climate system is clear, evident from increasing greenhouse gas concentrations in the atmosphere, positive radiative forcing, observed warming, and physical understanding of the climate system.
3 days ago · Climate change - Human Impact, Causes, Effects: The history of humanity—from the initial appearance of genus Homo over 2,000,000 years ago to the advent and expansion of the modern human species (Homo sapiens) beginning some 150,000 years ago—is integrally linked to climate variation and change.

Aug 5, 2019 · Scientists know that the warming climate is caused by human activities because: They understand how heat-trapping gases like carbon dioxide work in the atmosphere; They know why those gases are increasing in the atmosphere; They have ruled out other possible explanations

Nov 16, 2022 · Human behaviour is crucial in climate change mitigation, and in tackling the arising consequences. In this joint Focus issue between Nature Climate Change and Nature Human Behaviour, we take a...
It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century. The evidence for this has grown, thanks to more and better observations, an improved understanding of the climate system response and improved climate models.
