Question

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

Answer 1

Answer: 1. Necessary because it keeps heat in and keeps the planet at the right temperature for life.

It can harm the planet if more pollution occurs and the greenhouse gas effect traps too much heat and causes global warming. 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 Greenhouse gases let the sun's light shine onto the Earth's surface, but they trap the heat that reflects back up into the atmosphere. In this way, they act like the insulating glass walls of a greenhouse. The greenhouse effect keeps Earth's climate comfortable when the atmosphere traps heat radiating from Earth toward space. Certain gases in the atmosphere block heat from escaping. 3. Human activities contribute to global warming by increasing the greenhouse effect. ...

In this way, they act like the insulating glass walls of a greenhouse. 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. Geologic carbon sequestration is the process of storing carbon dioxide (CO2) in underground geologic formations. The CO2 is usually pressurized until it becomes a liquid, and then it is injected into porous rock formations in geologic basins. 5. As climate change caused by burning fossil fuels drives temperatures higher, the ocean warms, causing it to expand. This expansion in turn causes sea levels to rise. ... There is now so much warming baked in to the global climate system that sea levels will continue to rise for centuries.

Explanation:

Answer 2

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.
