is global worming really happening?

Answer 1

Global warming is the observed increase in the average temperature of the Earth's atmosphere and oceans in recent decades and the projected continuation of rising temperatures. Models referenced by the Intergovernmental Panel on Climate Change (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.[1] The uncertainty in this range results from both differing future greenhouse gas emission scenarios and uncertainties regarding climate sensitivity.

Global average near-surface atmospheric temperature rose 0.6 ± 0.2 °Celsius (1.1 ± 0.4 °Fahrenheit) in the 20th century. The prevailing scientific opinion on climate change is that "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,"[1] which leads to warming of the surface and lower atmosphere by increasing the greenhouse effect. Greenhouse gases are released by activities such as the burning of fossil fuels, land clearing, and agriculture. Other phenomena such as solar variation have had smaller but non-negligible effects on global temperature trends since 1950.[2]

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. These changes may increase the frequency and intensity of extreme weather events, such as floods, droughts, heat waves, hurricanes, and tornados. Other consequences include higher or lower agricultural yields, glacier retreat, reduced summer streamflows, species extinctions and increases in the ranges of disease vectors. Warming is expected to affect the number and magnitude of these events; however, it is difficult to connect particular events to global warming. Although most studies focus on the period up to 2100, even if no further greenhouse gases were released after this date, warming (and sea level) would be expected to continue to rise for more than a millennium, since CO2 has a long average atmospheric lifetime.

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 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 global warming.

The scientific process always produces some uncertainty. While scientists are used to dealing with this uncertainty, the public is not. While scientists speak in terms of the likelihood of specific negative consequences, the public wants definitive answers. The result is a kind of disjuncture, making it difficult for scientific information to be effectively communicated to the public. Good science must produce caveats; good communications must be concise. This paper is an attempt to examine this interplay, using the issue of global warming as an example. How does an understanding of scientific uncertainties influence the public’s opinion about global warming? How does the media explain these uncertainties? How do multiple sides of the global warming debate attempt to influence public opinion using these uncertainties? I attempt to answer these questions using four different sources of information: 1) I examine a random sample (n=150) of newspaper articles concerning global warming over a five-year period (1996-2000), with a special emphasis on the amount of scientific conflict within each article; 2) I examine public opinion about global warming over the same five-year period, using available US national opinion data; 3) I study recent major public education efforts about global warming, produced by environmental, governmental, and industry groups, with a particular emphasis on the types of scientific claims made by each; and, 4) I describe the results of a series of questions concerning global warming in the 2002 Detroit Area Study, in particular, the connections between opinions about the serious of global warming and perceived scientific consensus are examined. The results suggest a complex interaction between scientific caveats and public opinion.

Answer 2

yes global WORMING is really happening you pick the WORMS from your stomach u will find that they are the same from america to japan and very global in appeal

Answer 3

Global warming is really happening, as was revealed by a scientific panel a few weeks ago. About 90% of global warming is occuring as a cause of human involvement, meaning that the planet will start to see drastic changes in the next few decades

Answer 4

Global warming might make the Earth to hot for us in as early as 50 years. It will be very hard to survive if we don't do something about it, even though it's happening right now. I believe that elderly people don't care as much, because they'll probably be dead by then, but that's just me. It would help if you had a hybrid or something.

Answer 5

Yes, the live example is our earth today. It was due to global warming the there was an end to ice-age. It was happening , it is &it will remain to

Answer 6

On the surface it does appear the glaciers are breaking up (not sure relatively how much). There is a huge amount of research that has been done - most of it based on what they call Temperature anomalies. The definition of which is not readily discernable. I am just getting into this and have put together a resource page to study. The link is given below.

Answer 7

yes!global warming ie the increase in the average global temp. becoz of intesified greenhouse effect.

Answer 8

no, global wArming is happening, not global wOrming

Answer 9

i really dont know about global worming???? do u mean global warming, instead??

Answer 10

Well, what's really happening is global wArming, really.
