What are Positive and negative consequences of the greenhouse effect?

Answer 1

The good aspect of the greenhouse effect, which is caused by water vapor, mostly, plus some minor gases like carbon dioxide (CO2), is that it keeps the world from freezing into one, big ball.

The bad aspect is that carbon dioxide could turn it into an accelerated greenhouse effect, where the CO2 released from our burning of fossil fuels like coal, oil and natural gas have overwhelmed the carbon cycle and the natural greenhouse effect.

The accelerated greenhouse effect, with more and more CO2 and methane in the atmosphere is causing global warming, which is driving climate change.

Answer 2

It is required for life on Earth. Without the greenhouse effect, the earth will be freezing, too cold for life.

The bad thing is that us humans are throwing in way too many Greenhouse gases than normal, so now the planet is getting too hot, which leads to global warming.

Fortunatley, humans are now more aware of greenhouse gases and now are conserving more energy.

Answer 3

So called 'Greenhouse' gasses are needed, but only to a certain extent.

It is the amount that is the problem.

Were it not for greenhouse gasses then the earth would be too cold to be habitable.

If there is too much then there may be a 'runaway' effect and the earth will be too hot to be habitable. Much as Venus is today.

It is the balance we must try to achieve.

Answer 4

The natural greenhouse effect:

Positive effects:

• keeps the earth warm enough for life and has done for millions of years.

Negative effects:

• none really.

The enhanced greenhouse effect (caused by extra carbon dioxide in the atmosphere):

Positive effects:

• none really

Negative effects:

• Global warming, which is causing
• Climate change, which has many disadvantages
• Heat waves
• Crop failure and famine
• Sea level rises and flooding
• Climate refugees and Countries economies breaking down.
