Climate scientists have studied the effects the enhanced (or accelerated) greenhouse effect which is causing global warming and they are worried. They are worried because they have spread the message to the world but very few governments are prepared to take serious steps to combat the problem.
Yes. Without the greenhouse effect, the Earth would be uncomfortably (possibly unlivably) cold for most plants and animals alive today.
The earth has a greenhouse effect that keeps the planet warm. This is natural, supported by the carbon and water cycles, and has been going on for millions of years. Greenhouse gases like carbon dioxide and methane from human activities mean the earth is experiencing an enhanced, or accelerated greenhouse effect which is causing global warming.
Yes, you should be worried if it was not caused by mosquitoes or falliing.
The Sun heats the atmosphere of Venus up tremendously due to an out-of-control greenhouse effect. The average temperature on Venus is 460 C, or 860 F. The surface temperature of Venus is actually higher than that of Mercury.
Yes, scientists believe the young earth was hotter than it is today due to intense volcanic activity and higher concentrations of greenhouse gases in the atmosphere. This would have contributed to a much warmer global climate.
The earth's carbon and water cycles support a natural greenhouse effect in the atmosphere where just enough of the sun's heat is kept back so that life can go on comfortably. This is how the greenhouse effect helps us.But the greenhouse effect is now turning into an "enhanced" or accelerated greenhouse effect. This is causing global warming and is not helping us.Two hundred years ago we started digging up and burning fossil fuels (for industry, transport and to make electricity). Burning fossil fuels like coal, oil and natural gas releases all the carbon dioxide that had been hidden underground for millions of years. We also cut down the great forests of the earth, which can take carbon dioxide out of the atmosphere.These two things, burning fossil fuels and deforestation are disrupting the normal greenhouse effect, which is now becoming an enhanced greenhouse effect, caused by man.A:The sun sends light rays into the earth, but most of the light that hits the earth is reflected back into space. If carbon dioxide, along with water vapor, methane, sulfur hexafluoride, nitrous oxide, several types of chlorinated fluorocarbons and a few other gases, did not trap much of the reflected light, the earth would be so cold that no life could exist upon its surface. The trapping of the reflected light by gases is called the greenhouse effect.

The primary reason Venus is hotter than Earth is due to its thick atmosphere composed mainly of carbon dioxide, which creates a strong greenhouse effect that traps heat. This causes a runaway greenhouse effect on Venus, leading to extreme temperatures of around 450 degrees Celsius on its surface.
