Lady bird [3.3K]

Answer:

<em>The correct option is B) 5-10%</em>

Explanation:

We have seen and depicted various scenarios where we see how different changes arise and dominate the world. Social scientists suggest that as low as 5-10% people of a population are enough to bring about a change because people tend to copy what others are doing. Same goes for countries of the world. Each new popular technique which is learnt by one country tends to become popular and learnt by other countries. For example, the usage of a social app starts with a few members of a population using it and with time it becomes popular in the whole world.

1. Explain why the greenhouse effect is necessary but how an enhanced greenhouse effect can harm the planet.
LiRa [457]

Answer:

1. The enhanced greenhouse effect disrupts the Earth's climate equilibrium and has led to an increase in the global average surface temperatures.

2. Scientists attribute the global warming trend observed since the mid-20th century to the human expansion of the "greenhouse effect"   1 — warming that results when the atmosphere traps heat radiating from Earth toward space. Certain gases in the atmosphere block heat from escaping.

3. Greenhouse gases absorb some of the energy and trap it in the lower atmosphere. Less heat radiates into space, and Earth is warmer. ... Carbon dioxide, methane, water vapor, and nitrous oxide are naturally present in Earth's atmosphere.

4. Carbon sequestration is the process of capturing and storing atmospheric carbon dioxide. It is one method of reducing the amount of carbon dioxide in the atmosphere with the goal of reducing global climate change.

5. As climate change caused by burning fossil fuels drives temperatures higher, the ocean warms, causing it to expand. ... Scientists have found that water draining from melting glaciers and ice sheets in polar and mountain regions is now also contributing to this rise in sea levels.
