There is a natural greenhouse effect that keeps the planet warm. But that is not causing global warming. It is the enhanced greenhouse effect, caused by man, that is causing global warming.
Carbon dioxide is a naturally occurring greenhouse gas. At normal concentrations, it, along with other greenhouse gases, helps maintain global temperatures at a level that is comfortable for humans and other animals that have adapted to the present climate. This carbon cycle is the natural part of global warming.
By adding new carbon dioxide to the atmosphere, which we do by burning fossil fuels such as coal, oil and natural gas, and by cement manufacture, we interfere with the natural carbon cycle and create enhanced global warming. Throughout human history until the Industrial Age, atmospheric carbon dioxide levels were in the range 260-280 parts per million (ppm) and never higher than this. The increase in concentrations of carbon dioxide to the present level of over 400 ppm is accepted by research scientists as principally the result of human activity and so the resultant enhanced global warming is caused by human activity.
We have also destroyed huge forests all over the world (deforestation) that used to remove carbon dioxide from the atmosphere.

∙ 12y agoIt is caused by humans burning fossil fuel (coal, oil and natural gas) and cutting down forests. Both of these mean more carbon dioxide in the greenhouse gases in the atmosphere. The extra carbon dioxide is causing global warming, which is causing climate change.

∙ 8y agoBoth ! The Earth is still coming out of the last ice-age, which means temperatures will naturally rise over a lengthy period pf time. HOWEVER - since the industrial revolution, humans have been pouring tonnes of waste materials into the atmosphere - and it's only (relatively) recently that society has realised the damage that's been caused.

∙ 12y agoMost climate scientists (that is, about 97% of them) accept that global warming is being caused by the human activities of deforestation and burning fossil fuels (coal, oil and natural gas).

Does a hurricane cause global warming?
No, Hurricane Katrina caused flooding and terrible damage to humans and property, but it did not cause global warming. Global warming is caused among other things by man burning fossil fuels (coal, oil and natural gas) and putting greenhouse gases into the atmosphere.
How do humans contribute to climate change not including global warming?
Humans are contributing to global warming (by burning fossil fuel and cutting down forests) and global warming is CAUSING climate change.
Is global warming definitely caused by humans or is it a natural event that has happened before?
Global warming has happened before but it happened over many thousands of years. The present global warming is happening extremely fast (200 years) and is definitely being caused by human activity. We can measure the cause, the carbon dioxide in the atmosphere, and we can test to prove it comes from fossil fuels (coal, oil and natural gas).
How much of a role in global warming do humans play?
This depends on your point of view. If the Oregon Report is correct (which I believe it is) there is no such thing as global warming, On the other hand, most climate scientists say that recent global warming and climate change are caused substantially by human activities, such as burning fossil fuels (coal, oil and natural gas), manufacturing cement and deforestation.
What does global warming hurt?
Global hurts everything in the world. It hurts you, me, humans, animals, and many other things. Global warming is a problem that should be stopped early and not when it is starting to intensify.
Do you think humans have affected global warming?
Humans have caused it. -.-
Where does Al Gore get his money?
From lying about how humans caused global warming
Is global warming caused by humans or something you can control?
yes global warming is basisly caused by human we can control by using less electricity or less produce carbon dioxide!
If we wern't here would global warming happen?
No. Global warming is caused by man burning fossil fuels and cutting down forests. No other animal does that. If there were no humans on earth, there would be no global warming.
What percent of Americans support global warming?
No one would want to have global warming being caused by humans. That is not a logical position for anyone. Zero percent would WANT man induced global warming.
Is US the reason you have global warming?
No. Humans are the reason for Global Warming! Humans in big rich countries!
Does a hurricane cause global warming?
No, Hurricane Katrina caused flooding and terrible damage to humans and property, but it did not cause global warming. Global warming is caused among other things by man burning fossil fuels (coal, oil and natural gas) and putting greenhouse gases into the atmosphere.
Who caused global warming?
humans cause global warming, because they are the ones who mainly pollute or use to much hot water, The main point is humans cause global warming
How are coral reefs being destroyed by man?
Mainly by humans polluting atmosphere and by global warming we caused
Who is starting global warming?
Humans
Why did the environment end up the way it did in the movie wall-e?
Global warming and the humans abandoned it because of global warming. Global warming
How do humans contribute to climate change not including global warming?
Humans are contributing to global warming (by burning fossil fuel and cutting down forests) and global warming is CAUSING climate change.
