Global Warming is caused by the greenhouse effect in Earth's atmosphere. The greenhouse effect is what keeps the planet warm enough for life. This worked well till about 1750 when humans started burning coal for industry, the start of the Industrial Age.
Since then, the burning of fossil fuels (coal, oil and natural gas) has put more and more of the greenhouse gas carbon dioxide into the atmosphere. The destruction of forests has also contributed. This is known as the enhanced, or accelerated greenhouse effect.
The IPCC (the InterGovernmental Panel on Climate Change), set up by the United Nations, reports:
"Human activities, primarily the burning of fossil fuels and clearing of forests, have greatly intensified the natural greenhouse effect, causing global warming."
The main greenhouse gases that cause the greenhouse effect are:
Where these gases come from:
Other causes:
More detail:
The greenhouse effect has been keeping the Earth warm enough for human life since its beginnings. Infrared radiation comes from the sun into our atmosphere. The greenhouse gases of water vapor, carbon dioxide (CO2), methane and ozone (and a few others) absorb some of this heat into the atmosphere, thus keeping the planet warm.
However, since the 18th century, when we began to build factories, humankind has been slowly putting more and more CO2 into the atmosphere. Every time we burn coal, gas or oil we increase the amount of greenhouse gases. Now we use oil for transport and to generate electricity. This is why there we are urged to drive less, use public transport and cut our electricity use.
Forests too, which absorb carbon dioxide, have been cut down, and are still being cut down, all over the planet. With fewer trees, more of the CO2 goes into the atmosphere.
Population demand:
In 1800 the world population was less than one billion. Today it is close to 7 billion. Seven billion people wanting food, water and electricity and a share in the good life make a colossal demand on the resources of our planet.

Deforestation and the burning of fossil fuels.
There are no unpreventable causes of global warming. We could have prevented it, and we can still prevent the worst results if we act now.Change to renewable energyStop burning fossil fuels (coal, oil and natural gas)Replant the earth's forests.
Strictly speaking there is no other name for global warming."The whole earth heating up" might be another name.Global warming is causing climate change, so many people think they are both the same, so they say:"Climate change is another name for global warming", but they are not really the same.
There are several thesis statements one could make about global warming and its effects in the world. For example: Global warming is resulting in more frequent and more severe weather events.
"Climate Change" and "Global Warming" are not the same, though related. Global Warming causes Climate Change. With Global Warming we understand the warming of the earth's global temperature. That warming has in turn an effect on the earth's global climate and on more localized climates (like the climate of England or Western US).
A pamphlet on global warming should include information on the causes of global warming (greenhouse gas emissions, deforestation), the effects (rising temperatures, melting ice caps), and what individuals can do to help (reduce energy consumption, support renewable energy). It should also highlight the importance of taking action to combat climate change to protect the environment and future generations.
Ozone depletion causes global warming. This then causes global temperature to change.
Ozone depletion causes global warming. Global warming causes floods.
Pollution causes global warming. This global warming causes ozone depletion.
Pollution causes global warming. This global warming causes ozone depletion.
Carbon dioxide is denoted by CO2. It causes global warming. Global warming then causes ozone depletion.
Neither is particularly useful.
Global warming is heating of earth. It causes ozone depletion.
The causes of the Somerset floods is global warming.
Neither. Global warming has nothing to do with the hole in the ozone layer. The hole in the ozone layer has nothing to do with global warming.
Global warming is the increase of greenhouse gases. It causes various problems including ozone depletion.
