What does the greenhouse effect have to do with global warming?
Global Warming FAQThe "greenhouse effect" refers to the natural phenomenon that keeps the Earth in a temperature range that allows life to flourish. The sun's enormous energy warms the Earth's surface and its atmosphere. As this energy radiates back toward space as heat, a portion is absorbed by a delicate balance of heat-trapping gases in the atmosphere—among them carbon dioxide and methane—which creates an insulating layer.
Related QuestionsHow does the oxygen cycle relate to the greenhouse effect and global warming?
Carbon Dioxide Information Analysis Center (CDIAC) - Frequen...With recent developments it is now feasible to measure variations in the oxygen content of the atmosphere at the parts per million (ppm) level. Regular measurements of changes in atmospheric oxygen (O2) are currently being made at a number of locations around the world using two independent techniques, one based on interferometry and one based on stable isotope mass spectroscopy. Oxygen measurements can inform us about fundamental aspects of the global carbon cycle.
Related QuestionsWill Global Warming (from the Greenhouse Effect) result in an increase in mosquito-borne diseases?
FAQsThis is very difficult to determine. Currently there are different theories as to the level and amount of climate change. Some models predict large changes in rainfall patterns, while other predict small changes. We may expect with increases in rainfall there would be an increase in mosquito numbers and a subsequent increase in mosquito-borne diseases, however this may not be the case.
Related QuestionsAre global warming and the greenhouse effect the same thing?
Climate Cure 2025: Global Warming FAQIn a word, no! The greenhouse effect is a natural process whereby certain gases in our atmosphere (water vapor, carbon dioxide and methane for example) retain some of the infrared radiation that is emitted by the Earth. This process maintains the Earth's average surface temperature at about 60 F, making life possible. Without it, the Earth would be too cold for life to have developed here.
Related QuestionsWhat is an immediate effect due to global warming we are experiencing today?

Related QuestionsAre there scientists out there who do not believe in the greenhouse effect or global warming?
FAQs - SWCCIP - Our South WestNo, this is a myth. All scientists believe in the greenhouse effect. Without it the planet would be frozen. And all climate scientists accept that if humans put more greenhouse gases into the atmosphere then it will warm the planet. The only disagreement is over precisely how much the warming will be amplified by planetary feedbacks. However, there is scientific consensus that the average global warming of 0.
Related QuestionsIs there anything we can do about global warming?
Global Warming FAQYes! The most important action we can take to slow global warming is to reduce emissions of heat-trapping gases. Governments, individuals, and businesses can all help. Businesses can increase efficiency and save substantial sums by doing the same things on a larger scale. And utilities can avoid building expensive new power plants by encouraging and helping customers to adopt efficiency measures.

Related QuestionsWHAT IS THE DIFFERENCE BETWEEN THE GREENHOUSE EFFECT, GLOBAL WARMING AND CLIMATE CHANGE?
Climate Crisis FAQThese terms are often used to describe the same problem, but actually relate to cause and effect, or problem and consequence. The greenhouse effect is the cause - and global warming and climate change are the consequences. The greenhouse effect causes an accumulation of heat (or energy) in the Earth's atmosphere. The global climate must then adjust to deal with that extra accumulation of energy, and these adjustments result in global warming and climate changes.
Related QuestionsWhat is causing global warming?
Global Warming FAQScientists have concluded that human activities are contributing to global warming by adding large amounts of heat-trapping gases to the atmosphere. Our fossil fuel use is the main source of these gases. Every time we drive a car, use electricity from coal-fired power plants, or heat our homes with oil or natural gas, we release carbon dioxide and other heat-trapping gases into the air.
Related QuestionsIs global warming already happening?
Global Warming FAQYes. The IPCC concluded in its Third Assessment Report, "An increasing body of observations gives a collective picture of a warming world and other changes in the climate system.
Related QuestionsAre humans contributing to global warming?
Global Warming FAQIn 1995, the world's climate experts in the IPCC concluded for the first time in a cautious consensus, "The balance of evidence suggests that there is a discernible human influence on the global climate." In its 2001 assessment, the IPCC strengthened that conclusion considerably, saying, "There is new and stronger evidence that most of the warming observed over the last 50 years is attributable to human activities.
Related QuestionsWhich is it, global warming or climate change?
Global Warming FAQs - Understanding Climate Change - Frequen...Two 19th-century scientists are associated with the discovery that increasing carbon dioxide in the atmosphere warms the entire planet: French researcher Jean Baptiste Fourier and Swedish scientist Svante Arrhenius. Their identification of what came to be called the greenhouse effect (see box at right) applies to both natural and human-produced additions of CO2.
Related QuestionsHow does the greenhouse effect work?
Greenhouse: questions and answersThe greenhouse effect is a natural process. Sunlight passes through the atmosphere, warming the Earth’s surface. In turn, the land and oceans release heat, or infrared radiation, into the atmosphere, balancing the incoming energy. Water vapour, carbon dioxide and some other naturally occurring gases can absorb part of this radiation, allowing it to warm the lower atmosphere.
Related QuestionsClimate Cure 2025: Global Warming FAQIt is commonly stated that the greenhouse effect causes warming because greenhouse gases "trap" the heat, preventing it from escaping. This is a misconception! If all of the absorbed sunlight were trapped as heat, the temperature would be rising by 26 deg F per week, and the oceans would boil away in only 1500 years! This is totally contradicted by everyday experience as well as detailed observations of the climate system.Related Questions

Related QuestionsIs global warming connected to the hole in the ozone layer?
Global Warming FAQGlobal warming and ozone depletion are two separate but related threats. Global warming and the greenhouse effect refer to the warming of the lower part of the atmosphere (also known as the troposphere) due to increasing concentrations of heat-trapping gases. By contrast, the ozone hole refers to the loss of ozone in the upper part of the atmosphere, called the stratosphere.
Related QuestionsWill responding to global warming be harmful to our economy?
Global Warming FAQReducing our impact on the global climate does not have to hurt the world's economies. The answer depends much on the "how" and "when." The challenge is to strike a balance between responding early enough to avoid major negative (costly) impacts, and responding some time later in order to avoid taking big, expensive steps now which then may turn out to be unnecessary or inappropriate.
