Final answer:
The statement that global warming is a theory accepted by a majority of scientists is true with 97-98% of climate experts agreeing that human activities are causing global warming. major scientific institutions around the world support this consensus.
Step-by-step explanation:
The claim that global warming is a theory accepted by a majority of scientists is true. A significant body of research from climate experts supports the notion that the Earth's average surface temperature has risen notably in the last two centuries, particularly during the past century, due to human activities such as burning fossil fuels. This in turn results in an increase in greenhouse gas levels, which aggravates the greenhouse effect, trapping more heat in the Earth's atmosphere.
Scientific consensus is overwhelmingly in favor of the anthropogenic causes of climate change. According to surveys of the literature, between 97-98% of the most published climate researchers agree that human activities are the primary cause of the observed increase in global temperatures. This overwhelming agreement among scientists is reinforced by the endorsements of the academies of science in all the major industrialized countries. However, there seems to be a discrepancy between scientific consensus and public perception, with less than half of Americans aware of the scientific agreement on this issue.
