what are the affects of global warming?

Answer 1

Rise in ocean level due to the melting of glaciers.

Higher temperatures and mild winters.

Answer 2

There is now no doubt the world is getting warmer. The thermometers show that the world is warmer now than at any time since the measurements started. The year 1990 was the hottest year in the last century. Together with 1991, the years of 1983, 1987, 1988, and 1989, have been measured to be the warmest 6 years in the last hundred years. 1991 was the second warmest year of the past century, perhaps due to the eruption of Mt. Pinatubo during that year. The ash from the volcano in the upper atmosphere blocks some sunlight to earth, and is expected to generate a temporary two or three year cooling effect. After that time, most ash particles will have settled back to earth, and most scientists expect to see the global warming trend continue.

According to scientists, we can with "99% confidence conclude that current temperatures represent a real warming trend rather than a chance fluctuation over the 30-year period." Most scientists agree that the planet's temperature has risen 0.5 degrees Celsius since 1900, and will continue to increase at an increasing rate. The environment is responding to this warming. For instance, a study of mountain plants in the Alps (Europe), shows that some cold-loving plants are starting to move to higher and cooler altitudes. That is a possible response to increasing temperatures.

Answer 3

Oddly it depends to some extent on the cause. Increases in CO2 should only affect temperatures near sea level because CO2 is so heavy. Remember we are dealing with the transfer of accumulated diurnal heat.
If radiation can not transfer the heat it will be transfered by actual air movement during the night. This effects the highs and lows of atmospheric pressure on a daily basis. In short it effects the weather.
Sea level changes in temperature are unlikely to melt alpine glaciers.
Unfortunately a lot of the change appears to be an increase in light coming from the Sun, that very definitly will affect alpine glaciers. It will also afferct Polar ice caps and sea ice.
A rise in the temperature of the upper atmosphere would also enhance the Ozone layer, reducing UV light at the surface (a good thing-sunburn).
Sea level rises? Yes eventually, it has risen by about 400mm since the end of the "Little Ice Age" about 150 years ago and will probably continue to rise. (LOOK UP LITTLE ICE AGE)
Eventually you may find that you get slightly more warmer days and slightly fewer cold days than you did last century.
Climate Change is a statistical phenomena. Having a hot spell or a hurricane is not the direct result of Global Warming. We just had the coldest Christmas since 1888. Earlier this year we had the coldest May ever recorded in Australia.
Despite this I know from experience that if I compare the latest weighted average of State temperatures with those of 100 years ago they will be higher by nearly 0.5 C.
Growing seasons will lengthen especially in cooler Northern hemisphere zones. They were longer 500 years ago.
I guess that I'm saying that you will not notice much change in your lifetime-assuming that, unlike me, you are very young.

Answer 4

The anthropogenic greenhouse gas with the largest effect is carbon dioxide although the bulk of the greenhouse effect is actually due to water vapor. Global warming theories attempt to assess the extent to which increases in carbon dioxide levels affect the global climate though both direct and indirect means.

If the only variable considered is the emission of greenhouse gases related to human activity, then climate models predict that temperatures will increase in the future; however, the precise magnitude of these increases is still uncertain [4], with a range of +1.4°C to +5.8°C for the temperature change between 1990 and 2100. Much of this uncertainty results from not knowing future CO2 emissions, but there is also uncertainty about the accuracy of climate models and it is not clear if they under- or overpredict future climate change.

Although the discussion of global warming often focuses on temperature, global warming or any climate change causes changes in other things as well: overall precipitation and its patterns, cloud cover, weather, and all the other elements of our atmospheric system will be impacted by the increase in "radiative forcing" due to human changes in greenhouse gas concentrations in the atmosphere.

Possible explanations for observations of global warming are discussed in attribution of recent climate change.

Answer 5

1.significant slowing of the ocean circulation that transports warm water to the North Atlantic,
2.large reductions in the Greenland and West Antarctic Ice Sheets,
3.accelerated global warming due to carbon cycle feedbacks in the terrestrial biosphere, and
4.releases of terrestrial carbon from permafrost regions and methane from hydrates in coastal sediments.

The likelihood of many of these changes is uncertain. However, the probability of one or more of these changes occurring is likely to increase with the rate, magnitude, and duration of climate change.

The effects of global warming are not uniformly negative. Global warming will lead to climate change which will have positive benefits in some regions and negative effects in others. Scientists are unable to accurately predict when various effects of global warming will occur or what the magnitude of the effect will be

Answer 6

In reality, very little if anything. Check out some temperature charts and you'll see that the temperature has only risen 1 degree over the last 1000 years... that's global warming? I don't think so.

Answer 7

due to global warming theices on the poles is melt ..and if there was increase the level of global heating there will flood everywhere.and the earth will destroyed..

Answer 8

due to that earth's temperature would increase which results in melting of ice caps in polar region.In polar region temp is increasing faster than in equator.this due to the fact that the ozone layer gets badly affected in that region

Answer 9

The atmospheric temperature and leads to the depletion of the Ozone layer.

Answer 10

1. Increase in the atmosphreic temperature
2. Subsequently glaciers melt and rise in sea level
