Question

What is the hypothesis of global warming?

Answer 1

Hint: The hypothesis of global warming suggests that human activities are the reason for global warming. Studies made in accordance with the hypothesis have been put forward and discussed upon. Any contributor to global warming can become a part of a hypothesis of global warming, if it has scientific backing and is testable.

Complete answer:
A hypothesis is an educated guess which is based on observations made for an experiment. Usually, the experiment provides backing for the suggestion or the proposed explanation. It is a testable prediction made for a possible outcome. The most important characteristic of a hypothesis is that it has to be testable. A hypothesis can be proved wrong too. It is in the form of statements which convey the meaning clearly.
Global warming is a process that progresses gradually, where the Earth’s atmosphere experiences increased temperatures, in turn affecting the Earth’s surface and the oceans. This can be attributed to the Greenhouse effect, where entrapment of high levels of greenhouse gases like carbon dioxide, methane, CFC’s and various other gases in the atmosphere.
The hypothesis of global warming suggests that daily human activities are the major cause for global warming. When we burn fossil fuels for meeting our need for energy, massive amounts of carbon dioxide is released. The energy produced is usually required for transportation, electricity et cetera. We use refrigerators and air conditioners which release CFCs, due to which ozone layer is under danger. Holes in the ozone layer invite UV radiation to the Earth’s surface, which increases surface temperatures, and are also dangerous for living organisms. Whether it is a true prediction or not, it is true that humans have a major role and contribution in global warming.

Note:
A hypothesis relating to the interaction between the atmosphere and water bodies like oceans, where the increase in temperature in the atmosphere is seen due to drawing heat from the depths of the oceans is a suggested one. It is a good prediction, it might not be the sole reason, but one of the contributors.
