Is Climate Change Caused by Human Action

Introduction Are humans responsible for climate change? While it is evident that climate change is a result of different factors which when combined produce a hazardous effect, human action is considered to be the main cause of global warming. Numerous studies show that various human activities produce gas that traps heat which results in most of the increase in globally averaged temperatures. Clearly, atmospheric warming and cooling did not begin with people. It used to occur long before the rise of humankind through natural activities, such as volcanic eruptions, changes in the sun’s intensity and the already existing ...
