What are five facts about global Warming?

Answer 1

1. It is caused by humans emitting greenhouse gases into the atmosphere.

2. It is not natural, the earth is heating because of us.

3. If we don't change our ways, our planet will become inhabitable.

4. It causes warmer oceans, which means much stronger storms.

5. It isn't theory, out of 928 scientific articles, 0 disagreed with the reality of global warming.

6. If Greenland were to melt, (which it will if this continues) much of Florida, New York City, China, the Netherlands, and India would be underwater.

7. Global warming is paradoxical, it causes both droughts and famines.

8. Contrary to many beliefs, 'going green' will actually benefit the economy.

9. Americans are the highest contributors to global warming out of any other country on Earth.

10. By doing simple things such as turning down your thermostat, we can fix global warming.

A:

1. Global warming is happening, and it is being caused by human activity.
2. 97% of peer-reviewed climate scientists agree that this is so.
3. The main human activity causing it is burning of fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity. This releases carbon dioxide, a greenhouse gas.
4. There is a natural greenhouse effect, which keeps the earth warm enough for life. But we now have an enhanced greenhouse effect, from the extra carbon dioxide (CO2) in the atmosphere.
5. Carbon dioxide from fossil fuels was put away underground 300 million years ago. So releasing it now makes it extra, and the carbon cycle is only able to remove part of it. The carbon cycle is also weak because of deforestation. We have destroyed too many great forests of the world!
6. Human activity is emitting 60 billion tonnes of carbon dioxide into the atmosphere every year. That's a lot of gas!
7. Since the beginning of the Industrial Revolution, when we discovered we could burn coal and run steam engines, we have been increasing the levels of greenhouse gases (mostly carbon dioxide) in the atmosphere. Before that, CO2 levels were around 280 ppm (parts per million), and had been around that for 800,000 years. They are now almost 400 ppm, and will reach 500 ppm by 2050.
8. There are temperature records being broken all round the world. 2012 was the hottest year ever recorded for the United States. The ten hottest years ever recorded world-wide have all happened in the past twelve years.
9. Warming temperatures are making the ocean waters expand, and are melting the glaciers and ice caps. This is raising sea levels round the world. (Sea ice is melting earlier every summer in the Arctic, and refreezing later every year.)
10. The answer to global warming and climate change is to stop burning fossil fuels. Governments have to move to renewable energy (solar, wind, water, hydro, tidal and wave, geothermal, ocean thermal, biomass and biofuel), none of which adds extra carbon dioxide to the atmosphere.

A:

1. It's true.
2. It's caused by humans burning coal and oil.
3. We can help by changing to wind and solar electricity.
4. We can help by planting trees.
5. The greenhouse effect can't cope with the extra carbon dioxide so it's getting hotter every year.
6. Most scientists round the world agree that it is happening.
7. Melting glaciers and Greenland ice is raising sea levels. This will flood Pacific Islands and coastal cities.
8. We can help by reducing the amount of power we use.
9. Or change to renewable energy!
10. Bikes and walking, then buses and trains, then car-pooling. One person in a car is no help for global warming.

Answer 2

1. Carbon dioxide from burning fossil fuels (coal, oil and natural gas) is the main cause of global warming.
2. Deforestation is the other main cause, because trees remove carbon dioxide from the atmosphere.
3. We can still slow and maybe stop global warming by changing to renewable energy (solar, wind, water, hydro, tidal and wave, geothermal, ocean thermal, biomass and biofuel) to generate electricity.
4. In our own lives we can help by reducing our use of fossil fuels, turning off lights, reducing air conditioning and heating, recycling, making less use of private vehicles, etc.
5. We can also help by encouraging others, talking about it with our friends, contacting government representatives, learning more about it (WikiAnswers has lots of information), and setting a good example.

Answer 4

1. Global warming is the long-term heating of Earth’s climate system.
2. It is primarily caused by human activities such as burning fossil fuels and deforestation, which release greenhouse gases.
3. The impacts of global warming include rising temperatures, sea level rise, more frequent extreme weather events, and changes in ecosystems and wildlife.
4. Scientists agree that urgent action is needed to reduce greenhouse gas emissions and mitigate the effects of global warming.
5. Addressing global warming requires international cooperation and policies to transition to a low-carbon economy.
