A small number of scientists disagree that global climate change is caused by human activity. However, scientific consensus
supports the idea that human activity is affecting climate. This is possible because
Car and truck emissions go rise in the atmosphere. The atmosphere hold the ozone layer the ozone layer protects living things from violent UV rays. The emission gradually break the ozone and more UV ray light on us and heats the earth causing global warming.
The scientists that believe climate change is not caused by humans have this view because, climates on Earth have changed with ice ages and warming periods, which they believe is happening now.
