Energy comes from the sun principally in the form of visible light. When it passes through the earth's atmosphere and reaches the earth, this energy causes the surface to warm. The heat is then reradiated back into space as infrared radiation, or what we simply call heat. But some of this radiation is blocked by greenhouse gases, which prevent it from escaping into space, thus keeping the earth warmer than it otherwise would be. Finally, by increasing the amount of greenhouse gases in the air, we humans are creating an enhanced greenhouse effect, resulting in global warming.
What else can I help you with?
What are some man-made causes of global warming?
In nearly everything that we do we are the cause of global warming such as driving a car, turning on a light, or even the smoke from factories.
Is ozone depletion the cause why there is global warming?
Yes, it is. It is responsible for global warming.
Is global warming the main cause of the thinning of the ozone layer?
Global warming is a cause of the ozone depletion. However it is not the main cause of it.
Is global warming due to ice melting?
Ice melt is a consequence of global warming, not a cause of it. Though ice reflects light quite well, and as it melts, earth's albedo decreases, resulting in a feedback mechanism which further increases global warming.
Why earth have a global warming?
There is no such thing as "a global warming" global warming only happens to earth because human and our unruly decrease in the earths resources. HUMANS cause global warming.
Does the earth's crust cause global warming?
No. While events on the earths crust can cause global warming, the crust itself does not.
What could be an introduction for my speech on global warming?
A:Global warming is a very big issue in the world today. Global warming is when the earth's temperature rises. The cause of global warming is when greenhouse gases trap heat and light from the sun [in the atmosphere of the earth] causing the earth to heat up. Global warming affects animals and our environment, such as rise in sea levels which will cause extinction for more than a thousand species.
Does fishing cause global warming?
No.
What is the name that gives gases that trap heat and cause global warming?
Greenhouse gasses are the cause of Global Warming.
Is the main cause of the thinning of the ozone layer global warming?
The main cause of thinning is CFC's. Global warming also affects it.
How do polar bears cause global warming?
Polar bears do not cause global warming. In fact, polar bears are affected by global warming due to the shrinking of their sea ice habitat. The loss of sea ice reduces their hunting grounds and threatens their survival.
Can the ozone layer cause global warming?
Ozone depletion causes global warming. This then causes global temperature to change.
