According to the report, one in six adults in the UK don't think climate change is caused by humans.
Scientists and policymakers around the world agree that this is the case.
The study was conducted by King's College London.
The survey was done in six European countries.
The Director of the Policy Institute at King's called the finding a real concern.
The UN's Intergovernmental Panel on Climate Change said last year that human influence has warmed the atmosphere.
According to the study, the UK public does not know how much scientists agree on the link between human activity and climate change.
The majority of people in the UK accept humans' role in climate change, with a quarter of the public saying it is already damaging them.
In comparison to Germany and Poland, the number of people in the UK who think climate change isn't caused by humans is much lower.
According to the survey, older people were more optimistic about slowing climate change. More than half of those 55 and over think it's not too late to act on climate change.
