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.

BM&F | Brazilian Mercantile & Futures Exchange - FREQUENTLY ...It is a phenomenon caused by the accumulation of certain gases in the atmosphere, known popularly as greenhouse gases or GHGs, which hold heat within the surface of the Earth and contribute to its warming. The Kyoto Protocol states that the following GHGs should be regulated: carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbon (HFC), perfluorocarbon (PFC), and sulfur hexafluoride (SF6).
Related QuestionsFaqThe earth is surrounded by its gas atmosphere mainly composed of oxygen and nitrogen but also of other gases including carbon dioxide, (C02) methane (NH4), nitrous oxides, water vapour and other gases of industrial origin. An intrinsic property of these other gases is to absorb the energy of the sun radiations captured by the earth and reemitted in the atmosphere, mainly during the night.Related Questions

Carbon Planet Global Warming FAQThe main gases in the Earth's atmosphere, nitrogen and oxygen, are almost completely transparent to the sun's rays. But water vapour, carbon dioxide and other gases form a blanket around the Earth, trapping heat. This process is known as the greenhouse effect.Related Questions
FAQs - SWCCIP - Our South WestThe Sun's warmth heats the surface of the Earth, which in turn radiates energy back to space. Some of this radiation, which is nearly all in the infrared spectrum, is trapped in the atmosphere by greenhouse gases. For instance, water vapour strongly absorbs radiation with wavelengths between 4 and 7 micrometres, and carbon dioxide (CO2) absorbs radiation with wavelengths between 13 and 19 micrometres. The trapped radiation warms the lower atmosphere, or troposphere.Related Questions

Will 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 QuestionsWhat is the greenhouse effect? Is it the same as the ozone hole issue?
Frequently Asked Global Change QuestionsNo, they are two different (but related) issues.The greenhouse effect issue concerns the warming of the lower part of the atmosphere, the troposphere (the layer in which temperature drops with height; it is about 10-15 kilometers thick, varying with latitude and season), by increasing concentrations of the so-called greenhouse gases (carbon dioxide, methane, nitrous oxide, ozone, and others) in the troposphere.

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 QuestionsWhat is the enhanced greenhouse effect?
Greenhouse: questions and answersSince the industrial revolution and expansion of agriculture around 200 years ago, we have been raising the concentration of carbon dioxide gas in the global atmosphere. Levels of other greenhouse gases have also increased because of human activities. Higher concentrations of greenhouse gases in the Earth's atmosphere will lead to increased trapping of infrared radiation. The lower atmosphere is likely to warm, changing weather and climate.

Frequently Asked Global Change QuestionsWith 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 QuestionsWhat is the greenhouse effect, and is it affecting our climate?
NCDC: Global WarmingThe greenhouse effect is unquestionably real and helps to regulate the temperature of our planet. It is essential for life on Earth and is one of Earth's natural processes. It is the result of heat absorption by certain gases in the atmosphere (called greenhouse gases because they effectively 'trap' heat in the lower atmosphere) and re-radiation downward of some of that heat. Water vapor is the most abundant greenhouse gas, followed by carbon dioxide and other trace gases.
Related QuestionsWHAT CAUSES THE GREENHOUSE EFFECT?
Climate Crisis FAQThe greenhouse effect is caused by gases in the atmosphere which have the ability to absorb the sun's energy that is usually radiated back into space from Earth. Energy from the sun comes into the earth as short-wave radiation; some is absorbed and some is radiated back as long-wave radiation. The 'greenhouse gases' allow the short-wave radiation to pass through to Earth but absorb the long-wave radiation that is reflected back to space.
Related QuestionsHOW DO WE KNOW THE GREENHOUSE EFFECT IS A REALITY?
Climate Crisis FAQFirst, the fact that some gases have the ability of trapping heat is based on simple physics. No credible scientist questions this fact. Second, measurements since the mid-fifties have shown that the levels of greenhouse gases in the atmosphere are steadily increasing , and that these increases correspond to industrial emissions of greenhouse gases.
Related QuestionsWHEN WILL WE KNOW IF THE GREENHOUSE EFFECT IS HAPPENING?
Climate Crisis FAQThe Intergovernmental Panel on Climate Change (IPCC) stated in its 1990 report that "the unequivocal detection of the enhanced greenhouse effect from observations is not likely for a decade or more". However, recent events are leading to an reassessment of that statement by many scientists. Increasing number of scientists are declaring that the recently observed global warming trend is not natural and is likely to be linked to the greenhouse effect.
Related QuestionsWILL ALL THE IMPACTS OF THE GREENHOUSE EFFECT BE NEGATIVE?
Climate Crisis FAQThe effects of global warming and climate change will not impact the same way upon every region in the world, or upon all species of life. For example, a slight temperature increase in some of the colder parts of the world may create less hostile conditions for human habitation and improve conditions for agriculture. Similarly, changing rainfall patterns may favour some species over others.
Related Questionsmiddot; What is the greenhouse effect?
ESRL Global Monitoring Division - FAQ'sThe Sun, which is the Earth's only external form of heat, emits solar radiation mainly in the form of shortwave visible and ultraviolet (UV) energy. As this radiation travels toward the Earth, the atmosphere absorbs about 25% of it, and about 25% is reflected by the clouds back into space. The remaining radiation travels unimpeded to the Earth and warms its surface. The Earth releases back to space the same amount of energy it has absorbed from the Sun.
