“The term ‘climate change’ is meaningless. The Earth’s climate has been changing since time immemorial, that is since the Earth was formed 1,000 million years ago.” according to former NASA scientist Professor Les Woodcock in an interview by Neil Hudson. (Hudson, n.d,) There are thousands of scientists that would agree with that statement. Part of this statement as most truth to it. Yes, the Earth climate has been changing since the dawn of time first it was the “big bang” to the demise of the dinosaurs then the ice age. These climate changes are not small events in Earth’s history but major environmental impacts that were phenomenon. The temperatures on the Earth has risen about 1.4 degrees Fahrenheit from the early 20th century. Over this time, the levels of greenhouse gases, like carbon dioxide, methane and nitrous oxide, have also increased in our …show more content…
But it was until 1938 when an engineer named Guy S. Callendar had published a study that suggested that increased of carbon dioxide in the atmosphere was from fossil fuel and was causing global warming. Still many scientists were doubtful about Callendar theory and still argued that there was a natural explanation for the changes. A scientist named Charles Keeling had measured the levels of carbon dioxide in 1958 at the Mauna Loa observatory in Hawaii. With the information he collected, he became the first scientist to confirm that the carbon dioxide levels were rising and not being fully absorbed by the forests and oceans. When Keeling’s first reads of carbon dioxide levels stood at 315 parts per million in the Earth atmosphere. As time went on more and more studies came out and people slowly became more aware of the growing problem that the world was
