The greenhouse effect has kept the earth warm enough for millions of years. It was not a problem in the past because the carbon cycle kept the amount of carbon dioxide balanced. When we discovered coal in the 18th Century and started burning it, we released extra carbon dioxide into the atmosphere. This has caused the present enhanced greenhouse effect which is causing global warming.

It wasn't much of a problem for our species because we didn't exist when dramatic changes in the climate occurred.

Other climate changes occurred over long periods of time, giving species ample opportunity to adapt. At that, many species still went extinct during periods of significant change.

The primary reason climate change is a problem now is because human activity is driving it, and at a greatly accelerated rate.

Could the greenhouse effect occur on other planets?

The greenhouse effect is happening on any planet with greenhouse gas. Mars, as an example has greenhouse gases in it's atmosphere and has seen warming over the past hundred years similar to our warming trend. Venus, with an atmosphere of 96.5% carbon dioxide, has a runaway greenhouse effect which has caused the oceans to boil dry.

What is a sentence with greenhouse effect?

The greenhouse effect is the natural way that the Earth keeps warm. Too many extra greenhouse gases turn the greenhouse effect into an enhanced greenhouse effect. The enhanced, or accelerated, greenhouse effect is causing global warming.

What is another name for enhanced greenhouse effect?

The greenhouse effect is the natural process by which greenhouse gases keep the earth's temperature at a comfortable level suitable for human existence. The enhanced greenhouse effect is the increase in greenhouse gases that is leading to global warming. The term "enhanced greenhouse effect" is also referred to as the "anthropogenic greenhouse effect" and is the idea that humans may have an effect on global climate. It is also referred to as the "runaway greenhouse effect".

What contributes to maintaining the temperature on Earth?

The greenhouse effect maintains the temperature on earth as it has done for millions of years. The enhanced (or accelerated) greenhouse effect which is causing global warming has only been happening for the past 200 years.


What is the greenhouse affect?

The greenhouse effect occurs when certain gasses in the atmosphere trap infrared radiation. This effect makes the planet warmer than it would be without a greenhouse effect.The greenhouse effect is caused by greenhouse gases; the most important greenhouse gasses in Earth's atmosphere are: water vapor, carbon dioxide, and methane.Recently, the greenhouse effect has gotten stronger. Scientists believe this is because humans have been using large amounts of fossil fuels, which release carbon dioxide when they are burned. Since carbon dioxide is a greenhouse gas, it has caused the planet to warm over the past 150 years.
