Why was the concern over global cooling replaced with a concern over global warming?
Answers
Global cooling was a speculation or hypothesis that emerged in the 1970s of the looming cooling of the Earth's surface and atmosphere that would take place over a period of substantial glaciation. Global cooling emerged as a result of a temporary drop of temperature during the period of 1940s and 1970s. After this it was realized that it is not a real threat as global warming.
On the other hand, Global warming is the gradual rise in overall temperature of the atmosphere worldwide which is caused by greenhouse effect that is as a result of rise in the levels of greenhouse gas emissions such as CFCs and carbon dioxide.
Global warming is a present threat in the society world over with the rise in temperatures and climatic changes taking place, this is the reason why global warming replaced global cooling.
Global cooling refers to the cooling of the Earth's surface and its atmosphere, that takes place when there is substantial glacial period.
When their was a temporary fall in the temperature of the environment in the era of 1970's this concept gained much attention.
This concept doesn't pose a threat to the environment.
Global warming refers to the gradual rise in overall temperature of the atmosphere of the world.
Global warming is the causal effect of 'greenhouse effect'.
Greenhouse effect refers to a rise in the levels of greenhouse gas emissions , for instance, carbon dioxide.
Global warming gained more concern over global cooling due to the rising frequent climatic changes caused by global warming.
