One of the most difficult environmental issues to deal with today is global warming, but before we start any discussion we must ask the question what is global warming?
When you google the question what is global warming you will get a host of web definitions to explain what is global warming. Each definition will pretty much tell you the same thing, global warming is the earth’s temperature rising a few degrees each year; thus causing the earth to warm up.
From this definition given for what is global warming, inquiring minds would also want to know what effects global warming will have on our environment, assuming the earth is designed to remain at fairly the same temperature throughout time. However, the truth is the earth’s climate has been in constant flux for 5 billion years.
