Explanation:

a. Scientists generally agree that global warming is taking place. Due to the study of the  earths atmosphere over time, scientist ave come to terms wit the fact tat global warming actually exists

global warming is the reduction in the ozone layer of the earth's atmosphere due to human activities . Human activities tat could lead to global warming are deforestation: te fallin down of trees . tree/plant inhale carbon iv oxide . when there is a release of carbon gases into the surrounding , there won't be trees to sap up this unsafe gases from humans.

Gases from burning of refuse and industrial layout: Gaseous effluents from industrial layout can contribute to global warming. carbon mono-oxide from the exhaust pipes of vehicles are injurious to mother nature.

When there is global warming, it will affect climatic changes, flooding. Due to the reduction in the ozone layer, radiation from the sun will get to us quickly , and can cause skin cancer.
