what is global warming?

Answer 1

Global Warming is misconception perpetrated by Liberals. The reasons for this are unclear, but the central idea behind it is used to further extremist environmental policies.

The truth is, global temperatures have been rising and falling in predictable cycles, which are commonly known as Ice Ages. Why Liberals would chose to overlook such common knowledge in favor of speculation is what is not clear.

While there is polution, and there needs to be improvement, using such bad science to achieve it is bad politics too.

Answer 2

You bring about a very nice question. Global warming is when our average temperature increases to a level due to the high amount of greenhouse gases in our atmosphere. Greenhouse gases include water vapor (a natural greenhouse gas, there is no stop to it), CO2, and fossil fuels. Of course, CO2 emissions are a critical component of global warming. If you did not know, petroleum is a hydrocarbon. Hydrocarbons give it away, they contain carbon. When these hydrocarbons are burned, they give off carbon dioxide. This adds onto global warming. The more we consume petroleum, the more we hurt the environment. This is why scientists want to find a way to put an end to CO2 emissions which really isn't possible. So we bring about several other options such as hydropower, nuclear energy, wind power, and solar panels. However, the government does not agree to nuclear energy because it will cause radiation in areas that we live in and much more. I have a lot to say haha.

Answer 3

Global warming is a natural phenomenon that keeps us alive on this planet. The only question is, does anything that humans do have enough of an impact to compete with nature. So far the answer is "no". Krakatoa and other natural catastrophic events dwarf man's affect on our climate, but even these events are nothing when you consider the ebb and flow of ice ages.

Hucksters with alarmist theories get grants and sell books if they manage to get the news media involved before there is any scientific peer review. Then politicians (usually lawyers) that are ignorant of science take up the cause to win votes, and all these things have a snowball effect, and that's where we are now. Scientists that know what's going on can't get published, and you can't get gov't grant money for exposing pseudo-scientific theories as bogus.
Real science is not done thru politics.

Definitions of Global Warming on the Web:

A gradual warming of the Earth's atmosphere reportedly caused by the burning of fossil fuels and industrial pollutants.

The progressive gradual rise of the earth's surface temperature thought to be caused by the greenhouse effect and responsible for changes in global climate patterns. An increase in the near surface temperature of the Earth. Global warming has occurred in the distant past as the result of natural influences, but the term is most often used to refer to the warming predicted to occur as a result of increased emissions of greenhouse gases.

Global warming is the gradual increase in global temperatures caused by the emission of gases that trap the sun's heat in the Earth's atmosphere. Gases that contribute to global warming include carbon dioxide, methane, nitrous oxides, chlorofluorocarbons (CFCs), and halocarbons (the replacements for CFCs). The carbon dioxide emissions are primarily caused by the use of fossil fuels for energy.

Aan increase of the earth's temperature by a few degrees resulting in an increase in the volume of water which contributes to sea-level rise

Strictly speaking, global warming and global cooling refer to the natural warming and cooling trends that the earth has experienced all through its history. However, the term "global warming" has become a popular term encompassing all aspects of the global warming problem, including the potential climate changes that will be brought about by an increase in global temperatures.

Global warming refers to an average increase in the Earth's temperature, which in turn causes changes in climate. A warmer Earth may lead to changes in rainfall patterns, a rise in sea level, and a wide range of impacts on plants, wildlife, and humans. Greenhouse gases make the Earth warmer by trapping energy inside the atmosphere. ...

An overall increase in world temperatures which may be caused by additional heat being trapped by greenhouse gases.

The greenhouse effect acts to warm the plant and increase average global temperatures. This is seen as a major environmental hazard as average temperatures rise, leading to a possible change in weather patterns and agricultural output. This also may lead to melting of the polar ice-cap and a corresponding rise in sea level (Martin et al, 2000).

An increase in the temperature of the Earth's surface caused by trapping infrared radiation in carbon dioxide, increased amounts of which are produced by burning fossil fuels.

The gradual warming of the earth due to the "greenhouse effect".

An increase in the average temperature of the earth's atmosphere, especially a sustained increase sufficient to cause climatic change. Most scientists believe that a rise in carbon dioxide levels (caused by automobile, power plant, and other emissions) will lead to further global warming.

The hypothesis that Earth's atmosphere is warming because of the release of "greenhouse gases," such as carbon dioxide. These gases are released into the air from burning gas, oil, coal, wood and other resources which then holds heat in an action similar to the walls of a greenhouse.

Also called climate change. The slow increase of the Earth's surface temperature. It has resulted from both natural causes such as warming during an interglacial period and from the increased release of human-made greenhouse gases into the air through the burning of fossil fuels. Extreme or abrupt changes in climate may also occur, rather than just gradual warming.

An increase in the Earth's temperature caused by human activities, such as burning coal, oil and natural gas. This releases carbon dioxide, methane, and other greenhouse gases into the atmosphere. Greenhouse gases form a blanket around the Earth, trapping heat and raising temperatures on the ground. This is steadily changing our climate. See Also Greenhouse Gas,

Is the gradual increase of the temperature of the earth's lower atmosphere as a result of the increase in greenhouse gases. Sustained increases in atmospheric temperature may result in climatic change.

The steady, documented rise in the Earth’s average surface temperature over the last century. The trend is largely attributable to the increased accumulation of greenhouse gases in the atmosphere. Climate change believed to be linked to global warming (eg, more frequent droughts, new hurricane patterns, melting of glaciers) is already occurring in some regions of the globe.

Increased levels of gases such as carbon dioxide that trap heat in the earth's lower atmosphere potentially causing global warming

The earth has warmed up by about 0.6ºC in the last 100 years. During this period, human emissions of greenhouse gases have increased, largely as a result of the burning of fossil fuels and deforestation. Scientists now think that these increased emissions, leading to the enhanced greenhouse effect, are the cause of global warming.

Heating that occurs when carbon dioxide traps the Sun’s heat near Earth’s surface, causing Earth’s temperature to rise

As a result of increasing atmospheric CO2 concentrations the global average surface temperature is rising. Weather patterns are changing as temperatures rise with more frequent incidencies of floods and drought

The view that the earth's temperature is being increased, in part, due to emissions of greenhouse gases associated with human activities such as burning fossil fuels, biomass burning, cow and sheep rearing, deforestation and other land use changes. (see climate change, Kyoto Protocol and UNFCCC)

The expected consequence of an increase in the concentration of greenhouse gases by human activity (see greenhouse gases).

The theoretical increase of global temperatures caused by the greenhouse effect.

The warming of the lower atmosphere due to the increased emission of greenhouse gases.

Changes in the surface-air temperature, referred to as the global temperature, brought about by the greenhouse effect which is induced by emission of greenhouse gases into the air.

an increase in the average temperature of the earth's atmosphere (especially a sustained increase that causes climatic changes)

Global warming is a term used to describe an increase over time of the average temperature of Earth's atmosphere and oceans. Global warming theories attempt to account for the rise in average global temperatures since the late 19th century (0.6 ± 0.2°C) and assess the extent to which the effects are due to human causes. ...
