    Extractions: Reducing Emissions The amounts of greenhouse gases, such as CO , CH , in the atmosphere can be reduced either by controlling emissions or by increasing the rate at which they are removed. The principal anthropogenic sources of CO are combustion of fossil fuels and cement manufacture (about 6GtC/y) and deforestation (about 2GtC/y). Fossil fuels are used for power generation, transport, heating and many other purposes. The second most important greenhouse gas is methane. Anthropogenic sources of methane emit about 375 Mt/y (whereas natural sources only produce about 160Mt/y); methane is emitted as a result of production and use of fossil fuels but much more comes from disposal of solid and liquid wastes, agriculture, particularly growth of rice, and from ruminant livestock. Reducing emissions of CO could be achieved, for example, by reducing the demand for energy, by altering the way that energy is used, or by changing the method of producing/delivering energy. Demand for energy can be influenced by fiscal measures and changes in behaviour but, in the technical area, there are 3 distinct types of option for reducing emissions: improving energy efficiency switching to low carbon fuels switching to "no-carbon" fuels

    Extractions: October 1, 2002 RELEASE: 02-142 LANDCOVER CHANGES MAY RIVAL GREENHOUSE GASES AS CAUSE OF CLIMATE CHANGE While many scientists and policy makers have focused only on how heat-trapping gases like carbon dioxide are altering our global climate, a new NASA-funded study points to the importance of also including human-caused land-use changes as a major factor contributing to climate change. Land surface changes, like urban sprawl, deforestation and reforestation, and agricultural and irrigation practices strongly affect regional surface temperatures, precipitation and larger-scale atmospheric circulation. The study argues that human-caused land surface changes in places like North America, Europe, and southeast Asia, redistribute heat regionally and globally within the atmosphere and may actually have a greater impact on climate than that due to anthropogenic greenhouse gases combined. The study also proposes a new method for comparing different human-influenced agents of climate change in terms of the redistribution of heat over land and in the atmosphere. Using a single unit of measurement may open the door to future work that more accurately represents human-caused climate change.

    Extractions: The Greenhouse Effect, Greenhouse Gases, and Global Warming By Harvey Augenbraun Elaine Matthews , and David Sarma greenhouse effect . The following sections provide overviews of the greenhouse effect, atmospheric greenhouse gases, and sources and sinks of the gases. Much of the energy absorbed at the Earth's surface is radiated upward as infrared (IR) thermal energy. Several gases that occur naturally in the atmosphere absorb this infrared energy and re-radiate it back to the surface. Therefore, heat that would be lost to space is trapped near the surface. The effect of the atmosphere and its heat-absorbing gases warms the Earth's surface and the Earth's surface therefore reaches radiative balance at a higher temperature than if there were no atmosphere, or an atmosphere without IR-trapping gases. The term "greenhouse" is used to describe this phenomenon since these gases act like the glass of a greenhouse to trap heat and maintain higher interior temperatures than would normally occur. The atmospheric gases most responsible for this effect are water vapor (H O), carbon dioxide (CO

48. Chilly Forecast
    Worried about global warming? Maybe you should be. According to the science journal Nature, we may actually be in the early stages of a new ice age. Scientists in Antarctica, drilling more than two miles down through the ice, say there's evidence that the Earth has endured four long ice ages each lasting up to 100,000 years and that we appear to be about 18,000 years into a fifth. This, despite the fact that the temperature has been rising steadily now for 100 years. While industrial pollution is to blame for some of the temperature increase, at least part of it is caused by natural greenhouse gases which have always existed. Still, it seems at tad warm for being 18 millennia into an ice age. Wired News

    Extractions: Many chemical compounds present in Earth's atmosphere behave as 'greenhouse gases'. These are gases which allow direct sunlight (relative shortwave energy) to reach the Earth's surface unimpeded. As the shortwave energy (that in the visible and ultraviolet portion of the spectra) heats the surface, longer-wave (infrared) energy (heat) is reradiated to the atmosphere. Greenhouse gases absorb this energy, thereby allowing less heat to escape back to space, and 'trapping' it in the lower atmosphere. Many greenhouse gases occur naturally in the atmosphere, such as carbon dioxide, methane, water vapor, and nitrous oxide, while others are synthetic. Those that are man-made include the chlorofluorocarbons (CFCs), hydrofluorocarbons (HFCs) and Perfluorocarbons (PFCs), as well as sulfur hexafluoride (SF ). Atmospheric concentrations of both the natural and man-made gases have been rising over the last few centuries due to the industrial revolution. As the global population has increased and our reliance on fossil fuels (such as coal, oil and natural gas) has been firmly solidified, so emissions of these gases have risen. While gases such as carbon dioxide occur naturally in the atmosphere, through our interference with the carbon cycle (through burning forest lands, or mining and burning coal), we artificially move carbon from solid storage to its gaseous state, thereby increasing atmospheric concentrations.

55. Many Scientists Believe Runaway Greenhouse Effect Possible!!
    A Greenpeace poll (in 1992) shows that a worryingly high proportion of climate scientists believe it possible that continuing emissions of greenhouse gases can awaken synergistic feedbacks capable of generating a runaway greenhouse effect.

    Extractions: A Greenpeace poll shows that a worryingly high proportion of climate scientists believe it possible that continuing emissions of greenhouse gases can awaken synergistic feedbacks capable of generating a runaway greenhouse effect. Bad though the best- estimate of the future, as portrayed by the IPCC would be, there is a worst-case view, which is that the IPCC estimates will prove to be underestimates, and that natural amplifications of warming (positive feedbacks) will be awakened, potentially even generating a point of no return beyond which might lie unstoppable heating of the planet, no matter how deeply anthropogenic emissions might ultimately be cut. The results of an opinion survey on this subject, published by Greenpeace at the 1992 American Association for the Advancement of Science annual meeting in Chicago, show that almost half of surveyed world climate scientists believe that a runaway greenhouse effect is possible if action is not taken to cut greenhouse gas emissions. More than one-in-ten of those polled believe this worst-case analysis - a point of no return beyond which lies unstoppable heating of the atmosphere - to be probable. Greenpeace International polled 400 climate scientists during December 1991 and January '92. The sample included all scientists involved in the 1990 study of the Intergovernmental Panel on Climate Change, and others who have published on issues relevant to climate change in `Science' or `Nature' during 1991. Scientists were asked whether they thought there would be a point of no return at some time in the future, if emissions continued at their present rate. By the end of January 1992, 113 had replied, in the following way: probably - 15 (13%), possibly - 36 (32%), probably not - 53 (47%). In other words, 45% believe the runaway greenhouse effect to be possible.

It’s actually a mixture of gases that surrounds the Earth, performing many functions and helping to support life on our planet. The Earth is a huge greenhouse? As you know, greenhouses use glass to keep the heat in. And just as the glass in a greenhouse holds the sun’s warmth inside, so the atmosphere traps the sun’s heat near the Earth’s surface. This keeps the Earth warm using what are called “greenhouse gases”. Without these gases, the sun’s heat would escape and the average temperature of the Earth would drop from 15 degrees Celsius to – 18 degrees Celsius!
