what`s is a global warning,.??

Question

pleas help me thank very muc

Answer 1

Global Warming is a farce. It was created by left-wing liberals for political gain and as a scare tactic just like they did for Y2K over seven years ago. In fact, it is no longer called Global Warming, they have since changed it to "Climate Change Crisis" due to all of the record low temperatures the world has witnessed this past winter.

25 years ago liberals were claiming the earth was cooling and that we should take measures not to destroy any natural heating resources from the earth. That too was proven to be a farce.

Bottom line... Global Warming doesn't exist and the sky is NOT falling! Live life, enjoy it, and keep producing those gasses because the earth can handle it.

Answer 2

Global warming is the observed increase in the average temperature of the Earth's near-surface air and oceans in recent decades and its projected continuation.

Global average air temperature near Earth's surface rose 0.74 ± 0.18 °C (1.3 ± 0.32 °F) during the last century. The Intergovernmental Panel on Climate Change (IPCC) concludes, "most of the observed increase in globally averaged temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations," which leads to warming of the surface and lower atmosphere by increasing the greenhouse effect. Other phenomena such as solar variation and volcanoes have probably had a warming effect from pre-industrial times to 1950, but a cooling effect since 1950.These conclusions have been endorsed by at least 20 scientific societies and academies of science, including all of the national academies of science of the G8 states. Some scientists disagree with parts of this conclusion as does the American Association of Petroleum Geologists. Only a few of these dissenting scientists specialize in climate science.

Models referenced by the IPCC predict that global temperatures are likely to increase by 1.1 to 6.4 °C (2.0 to 11.5 °F) between 1990 and 2100. The range of values reflects the use of differing scenarios of future greenhouse gas emissions as well as uncertainties regarding climate sensitivity. Although most studies focus on the period up to 2100, warming and sea level rise are expected to continue for more than a millennium even if no further greenhouse gases are released after this date. This reflects the long average atmospheric lifetime of carbon dioxide (CO2).

An increase in global temperatures can in turn cause other changes, including a rising sea level and changes in the amount and pattern of precipitation. There may also be increases in the frequency and intensity of extreme weather events, though it is difficult to connect specific events to global warming. Other consequences include changes in agricultural yields, glacier retreat, reduced summer streamflows, species extinctions and increases in the ranges of disease vectors.

Remaining scientific uncertainties include the exact degree of climate change expected in the future, and especially how changes will vary from region to region across the globe. A hotly contested political and public debate also has yet to be resolved, regarding whether anything should be done, and what could be cost-effectively done to reduce or reverse future warming, or to deal with the expected consequences. Most national governments have signed and ratified the Kyoto Protocol aimed at combating greenhouse gas emissions.

This website answers the question - http://profend.com/global-warming/pages/questions.html#1

You'd do well to avoid the previous answer as it's nonsense. Global warming has been a scientific issue far longer than a political one, In 1811 global warming was 'discoverred', in 1896 the links between greenhouse gases, global warming and climate change were established. 92 years later it first appeared on the political aggenda.

The name hasn't been changed to climate change. Global warming is (and always has been) the cause and climate change is (and always has been) the effect - they're two different things.

There have been no record lows this winter. Globally it's been the hottest on record. Some places (western US and western Canada) experienced slightly lower than average temperatures, some places (mid and northern US) experienced normal temperatures, the rest of the world was hotter.

Answer 4

Some gases ("greenhouse gases") let sunlight in, which warms the Earth, and then block that heat from leaving. That's the "greenhouse effect", and it's a natural thing, mostly caused by water vapor.

Man is making excessive amounts of greenhouse gases, mostly by burning fossil fuels. That causes the delicate natural balance to go out of whack and the Earth warms. That's global warming.

It won't be a Hollywood style disaster. Gradually coastal areas will flood and agriculture will be damaged. But it will be very bad. Rich countries will cope, but it will take huge amounts of money. In poor countries many people will die of starvation, but not all of them.

Most scientists say, in 20-50 years. But we need to start right now to fix it, fixing it will take even longer than that.

Answer 5

it's not a globle warning, its called global warming and its when the earth is in danger of deplieating(ruining) the atmophere and it can be caused by a number of things, hairspray, arosole, even the burning of coal.
