It "found important gaps in knowledge and common misconceptions about climate change and the earth system. These misconceptions lead some people to doubt that global warming is happening or that human activities are a major contributor, to misunderstand the causes and therefore the solutions, and to be unaware of risks," the report said.Half of Americans recognize that global warming is a result of human actions. Fifty-seven percent understand that the greenhouse effect describes gasses that trap heat in the atmosphere, and 45 percent know that carbon dioxide traps heat from the surface of the Earth. Just a quarter know about coral bleaching and ocean acidification, the study revealed.
What is very clear about these surveys is that a lot of work needs to be done to enlighten ordinary people about the causes of global warming, and the impact on our societies of the climate change that is coming.
