What are possible outcomes of global warming?
The potential results of temperature change can affect people in many areas of the world. The main outcomes could be:
- Melting of sea ice can cause flooding from an increase in worldwide sea levels.
- Changes in global weather patterns can create stronger storms.
- Changes in wind currents that affect precipitation can increase the length and severity of droughts.
- Sea levels will rise, causing floods
- An increase in the spread of disease will occur.
- The northern polar icecap, between Canada and Russia is almost completely ice free during the summer months.
- The melting of ice from the Arctic and a resultant rise in the
sea level of the oceans.
- Hurricanes and other extreme weather will increase.

Global warming could be influenced by a variety of factors. Millions of years ago a salt water fern absorbed CO2 from the atmosphere. As the ferns died they sank and that carbon became sequestered on the deep sea floor. The result was a gradual cooling of the climate. Volcanoes also vent a lot of… hydrogen sulfide gas and particulate matter that reflects sunlight, resulting in cooler temperatures. Since the beginning of the industrial revolution, however, mankind has begun burning coal--much of which was carbon sequestered during the Permian some 300 million years ago, or during the later Mesozoic. In a short time (150 years) atmospheric CO2 levels have risen from 280 parts per million to over 390 ppm today. As we continue to pump 30 billion tons of CO2 into the atmosphere each year from fossil sources, this heat trapping gas will result in an inevitable rise in global temperature. (MORE)
Global warming is everywhere, and everyone is affected. Oceans rise and cause inland migration, and temperatures rise to deadly conditions.
We have global warming because of deforestation and fossil fuels (coal, oil and natural gas). When we discovered coal, and how powerful it was in driving steam engines, we were delighted. This was 300 years ago, and we didn't realise then that the carbon dioxide (CO 2 ) from the burning coal wo…uld be too much for the carbon cycle to remove. We didn't realise that by cutting down the forests all over the world this would mean that more carbon dioxide would be left in the atmosphere. We didn't understand then, about the greenhouse effect, and that greenhouse gases building up in the air capture more and more of the sun's heat. Now we understand, but governments and people won't make the hard decisions to save our children and grandchildren from a hot and dangerous future! (The hard decisions are, of course, to change from fossil fuel to renewable energy, and to replant thousands of forests!) (MORE)

Global warming will soon affect everyone. An estimate said that by2050, the air throughout the world will be so polluted that peoplewill always be sick, and masses will die of it. Global warming maycause the extinction of humanity eventually, and maybe all otherspecies.
Global warming is caused by human activity. The planet is warmingand this warming is changing the climate. Sea levels are rising andthreaten many low-lying areas and cities permanently.
Global warming is self explanatory. It is the concept where the earth warms up. It is also the reason for climate change. When the temperature of the planet as a whole increases, this increases the amount of ice that melts at the polar icecaps and in glaciers. This then leads to sea levels rising…, causing lowest level land areas to go under water and to a higher probability of flooding in the remaining low level land areas. Also sea temperatures increase in general leading to the increase and severity of hurricanes. The above are just the basics. The earth is a complex system so many other changes occur. Alpine regions become isolated from each other, thus certain species become "trapped" on a particular mountain because it is too warm for them to migrate to other mountains. Sea streams become affected, thus leading to greater rainfall in some areas and lesser rainfall in others, as well as increased temperatures in some areas and lesser temperatures in others. (MORE)

There are various possible consequences of global warming. Forexample, the ice caps will melt and many parts of the world will beunderwater.
in order of their contribution to greenhouse emissions 1) The ocean. (caused by heat from the sun) 2) Volcanoes (extraordinarily massive CO2 emitters) 3) Nature (mammals, dead plants) 4) People (the smallest CO2 producing entity's on earth)
If all the polar ice caps melted because of global warming it would significantly reduce the land masses because of the increased sea levels but the real issue would be the reduced salinity in the oceans. Coastal communities and cities would be seriously effected or lost due to the increased sea lev…el. (MORE)
We expect the climate will change. Some areas will receive more rainfall. Others will receive less. If enough of the Amazon rain forest dries and burns, much of the carbon sequestered there will be released as CO2, driving temperature up even faster. Although the south polar icecap is not likely …to get warm enough to melt for centuries to come, part of it seems unstable and may slide into the ocean and melt. In particular, Greenland ice is melting faster and faster, and that alone could raise ocean levels several meters. This means increased flooding of low lying areas. Global warming is also expected to increase the rate of animal migrations and of extinctions, and increase the spread of tropical diseases. For example, africanized "killer bees" have not spread very far north because they cannot take the cold, but it is likely they will be able to migrate further as temperatures increase. There will be some advantages. More northerly climates may experience an extended growing season, and as noted, some areas are expected to receive more precipitation. (MORE)
No because the Kyoto protocol assumes human beings are responsible for global warming. This is unlikely to be the case because the earth has gone through numerous cycles of warming and cooling going back long before human beings were a significant presence on this planet. Ever heard of the Ice Ages?… There were several. Global warming and cooling are a function of solar activity and people can't control the sun. (MORE)
Polar ice caps melting: The ice caps melting is afour-pronged danger. Beach erosion, low countries flooded, economiccost of repair and prevention. . Economic consequences: Most of the effects ofanthropogenic global warming won't be good. And these effects spellone thing for the countries of the …world: economic consequences.Hurricanes cause billions of dollars in damage, diseases cost moneyto treat, changes in agricultural practices to continue to providefood will be expensive and control and conflicts exacerbate all ofthese. . Increased probability and intensity of droughts and heatwaves: Although some areas of Earth will become wetter due toglobal warming, other areas will suffer serious droughts and heatwaves. Africa will receive the worst of it, with more severedroughts also expected in Europe, with millions at risk ofstarvation. . Warmer waters and more hurricanes : As the temperature ofoceans rises, so will the probability of more frequent and strongerhurricanes. We saw in this in 2004 and 2005. . Spread of disease : As northern countries warm, diseasecarrying insects migrate north, bringing disease to humans andagriculture. A: More heat mean more energy. More energy could mean a totalmeltdown of the icecaps on the poles. That in turn would not be sogood because sea water levels would raise. It would mean bigproblems for countries like Netherlands and part of Denmark. Manycoastal cities could/would be flooded. New Orleans, New York, andof course other seafront cities as well all over the world. Theextra amount of energy all over the world due to a warmer climatecould make thunderstorms more ferocious. Today's Twisters couldturn into super-twisters. The warmer climate will kill off a lot ofplants, insect and animal life all over the world, both in the seaand above. Coral reefs will be destroyed. The effect of risingseawater temperature can today be seen many places where seaweeddies off at a rapid rate. When seaweed dies it leaves the smallfish without protection. The whole balance of nature is to acertain degree changing. A: They say as the earth warms, and the ice melts at both or eachsouth and north poles the oceans will rise as well as their temps,the water that is evaporated into the atmosphere will cause moreviolent storms that is 1 example. 2nd example, the earth willbecome warmer, making it harder to grow food there will be in someareas less rain, and last the effect it will have on wildlife willbe very negative.

Why don't people get into their heads. YOU CANNOT STOP GLOBAL WARMING it is in nature. All you can do is postpone the inevitable. NO scientist of any stature has said you can stop it.

You can imagine the difference if it were possible to stop this 0.05% compared the 99.9% of other green house gases (water vapour etc.,). The answer would be like one of the top scientists said. It would be like an elephant charging with a fly on its back. Getting rid of the fly wouldn't stop the elephant from charging. (MORE)
The one way to slow down and stop global warming is to reduce our emissions of carbon dioxide and move as quickly as possible towards a carbon-neutral economy. This means being more efficient in our use of electricity, while phasing out coal and oil fired electricity generators in favour of alternat…ive energy sources. Similarly it means being more efficient in our use of oil for transport and finding as many replacement alternatives as possible. Even the cessation of deforestation would help, as would the restoration of forests. Some look for opportunities to sequester carbon dioxide underground, but this is an unproven technology that might not be reliable in the long term. (MORE)
The greenhouse effect, which is the way the greenhouse gases warm the atmosphere, is causing global warming (because humans have added extra carbon dioxide into the atmosphere by burning fossil fuels).
There are a number of ways in which global warming might lead to widespread deaths. For a start, the melting icecaps and glaciers will cause a rise in sea level which will lead to deaths from drowning. This will also cause loss of arable land, leading to food shortages and death through starvation. … Warmer temperatures and higher rainfall (hence more marshland) is likely to mean that tropical insects such as mosquitos can extend their range, bringing malaria to parts of the world where it has been rare or unknown. More extreme weather types could lead to more natural disasters like huricanes and flooding due to torrential rain. Finally - and most alarmingly - food shortages and loss of national territories could lead to conflict with many people being killed in wars as countries try to extend their borders by invading neighbouring countries in an effort to increase arable land for crop production.

It is difficult to predict the future, but in 2001 the IPPC issued a Report: Climate Change 2001: Working Group II: Impacts, Adaptation and Vulnerability (See the link below). Here are some of the suggested impacts on agriculture and forestry: . Climate change will affect crop yields and irri…gation demands. . Climate change will affect the composition and geographic areas of forests as well as product health and productivity. . Water Resources will be affected: water supply, quality and competition for water. . The following quote illustrates how much we rely on our ecosystems for goods and services: "Forests and woodlands provide many goods and services that society values, including food, marketable timber and non-wood products (fuel, fiber, construction material), medicines, biodiversity, regulation of biogeochemical cycles, soil and water conservation (e.g., erosion prevention), carbon reservoirs, recreation, research opportunities, and spiritual and cultural values." The report goes on to say that changes in climate are likely to affect all of these, especially the socio-economic systems. . Moderately warmer weather and increased CO2 in the atmosphere may help some crop growth (up 30% in the case of rice, soy and wheat), but with increased temperatures the grain yield drops 10% for every 1ËC rise above 26ËC. . Agricultural areas may suffer erosion from increased wind and water from short term changes in weather. . The growth of agricultural pests (weeds, insects and pathogens) under climate change is being studied with varying results. For example, higher temperatures increase the severity of rice leaf blast epidemics in cool subtropical zones, but in warm humid subtropics higher temperatures lower the severity of the epidemics. . Farm animals are affected by warmer temperatures, influencing their performances in growth, milk and wool production, reproduction, health and well-being. . Increased temperatures may lead to increased demand for water from agriculture and wildlife, including farm livestock. It may also lead to reduced water availability. . Adaption costs for agriculture, including retraining farmers for new practices, as well as the provision of new irrigation may be considerable. . The cost of basic food will rise, especially with temperature rises of more than 2.5ËC, as agriculture will not be able to absorb increased costs. . " Africa is projected to experience marked reductions in yield, decreases in production, and increases in the risk of hunger as a result of climate change." . Cold winters will no longer kill the eggs of the boreal forest insect pests. . Studies in Britain suggest that 10% of all Nature reserves could be lost in a few decades. . The effect of increased concentrations of CO2 on decomposition, plant productivity, and carbon storage could be just as damaging as the effects from climate change. (MORE)

Global Warming started when humans built machines and discoveredpetrol. All of the fumes went into the air causing Global Warming;like a greenhouse. Exactly right. About 250 years ago at the start of the Industrial Revolution man started burning coal and oil torun factories and vehicles. Then we s…tarted burning coal inelectricity power stations. Carbon dioxide had been stored in allthese fossil fuels for millions of years. Now this extra carbonwas suddenly released into the atmosphere where it turned thenormal carbon cycle upside down. The greenhouse effect, which hadbeen keeping the planet comfortably warm, suddenly turned into the enhanced greenhouse effect , warming up the planet much morequickly. This is causing global warming. A: Global warming is caused because of humansburning things such as coal or oil which releases greenhouse gassessuch as carbon dioxide into the atmosphere, thickening it andtrapping the sun's heat on Earth, thus causing a global warming. Wealso cut down all the forests so they can't suck the carbon out ofthe air. A: Principally increased carbon emissions fromburning fossil fuel, and deforestation for agricultural land. (MORE)

We can build devices to capture CO2 out of the atmosphere. CO2 has commercial uses, so some of it could be sold, and the rest buried somehow. About 50 million years ago there was a freshwater arctic fern known as Azolla. When the fern died, it would sink to the sea floor, locking away the CO2 it …had captured during its growth. Over the course of a few hundred thousand years earth's CO2 levels plummeted, and along with it the temperature, which resulted in a long series of ice ages. We could theoretically engineer some similar sort of organism, but we would need to be careful we didn't obtain the same result. Kudzu, for example, is not native to Florida. (MORE)

Global warming is a natural phenomenon in which naturally occurring greenhouse gases help maintain the world at a comfortable level suitable for human existence. However, the term is most often used specifically to refer to the rise, gradual at first but accelerating, in global average temperatures …since the beginning of the Industrial Age. Scientists in the nineteenth century concluded that changes in atmospheric carbon dioxide concentrations would lead to changes in global temperatures. They even calculated the temperature changes that would result from defined changes in carbon dioxide levels. Those calculation are now known to be in error because they did not adjust for the effects of the oceans, but when those adjustments are made, the results are quite consistent with recent modelling. Although the nineteenth century scientists had no reason to believe that global warming would one day be a serious problem, they had established that carbon dioxide was one potential cause of climate change. Scientists have observed changes in levels of the carbon isotope C 14 to establish that much of the carbon entering the air as carbon dioxide is not from recently living matter. They can estimate the volume of carbon dioxide emitted from time to time by volcanoes, and say that the remainder must come from mineral sources such as cement manfacture or fossil fuels. Scientists have observed changes in the ratios of the carbon isotopes C 12 and C 13 and say that although much of the carbon entering the air as carbon dioxide is not from recently living matter, it was living matter an extremely long time ago, thus coal, oil or natural gas (fossil fuels). Therefore burning fossil fuels is undoubtedly the major source of new carbon dioxide in the atmosphere. It is therefore the major cause of recent global warming, in addition to cement manufacture.

Yes, it is possible and in fact we must do so. We can either choose to begin now, while the short-tem economic cost of controlling global warming is still low and while temperatures can be stabilised only a little above present levels, or we can wait until the costs are high and the damage caused by… climate change is already quite apparent. We can control global warming by moving towards an economy that does not rely on emitting carbon dioxide and methane. We can use alternative fuels instead of fossil fuels, and we can become more fuel-efficient. We can also implement and enforce bans on deforestation. (MORE)
First, it is undoubtedly true that global warming is real. Accuratemeasurement show that the world really is warming up. For example,the last ten years were the warmest on record for the entire globe. It is true to a level of confidence between 97 and 99 per cent thatglobal warming is caused by gre…enhouse gases. From the level of carbon isotope C 14 in the atmosphere,scientists are confident that much of the increased level ofatmospheric carbon dioxide comes from carbon that has been buriedunderground for a very long time. This could be from burning fossilfuels, but could also be from manufacturing cement or from volcanicactivity. By using isotope comparisons for C 12 and C 13 , scientists have proven that the much of the increase from 260-280ppm to the present 390 ppm of atmospheric carbon dioxide comes fromcarbon that was once living matter. In combination with theC 14 analysis, this shows that the increased level ofcarbon dioxide is from burning fossil fuels. (MORE)
