Are humans responsible for climate change?

I'll find the latest scientific evidence on humanity's role in climate change.

Yes — according to the overwhelming scientific evidence and consensus, humans are responsible for modern climate change.

•NASA states: "There is unequivocal evidence that Earth is warming at an unprecedented rate. Human activity is the principal cause."

•Scientific syntheses state plainly that "Human activities, principally through emissions of greenhouse gases, have unequivocally caused global warming" and NASA likewise describes human activity as the principal cause

•NASA also summarizes: "Scientific evidence continues to show that human activities (primarily the human burning of fossil fuels) have warmed Earth’s surface and its ocean basins"

•The United Nations Intergovernmental Panel on Climate Change (IPCC) — the leading international body synthesizing climate science — has concluded:

•"there is at least 95% certainty that human activities are the principal cause"

•"It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century."

•In IPCC terminology, "extremely likely" corresponds to a confidence level of "95 percent or higher"

•A Carbon Brief analysis of the IPCC Fifth Assessment Report notes: "Humans emissions and activities have caused around 100% of the warming observed since 1950, according to the Intergovernmental Panel on Climate Change’s (IPCC) fifth assessment report."

•The same conclusion reflects an overwhelming scientific consensus. Multiple independent analyses find agreement "that humans are causing recent warming at roughly 97% or higher", with other assessments noting "97 percent to 99.9 percent of climate scientists agree that climate change is happening and that human activity is the primary cause."

Natural climate variability does exist and has caused climate changes over geologic time, but the rapid warming observed since the mid-20th century — documented by satellites, surface temperature records, ocean heat content, ice loss, and greenhouse gas measurements — is consistent with human-caused greenhouse gas emissions and cannot be explained by natural factors alone.
