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.

Replant billions of trees all over the world. . Stop burning fossil fuels (coal, oil and natural gas) inindustry, transport and the generation of electricity, whichreleases c…arbon dioxide (CO 2 ). . Start using renewable energy (solar, wind, water, hydro, tidaland wave, geothermal, ocean thermal, biomass and biofuel) togenerate electricity.
There are various possible consequences of global warming. Forexample, the ice caps will melt and many parts of the world will beunderwater.
Probably the most worrying impact of global warming will be the rise in sea level, especially in countries such as Bangladesh or the Netherlands, which have large areas close …to or below sea level. A: . The polar ice caps melt, raising the sea levels. . There would be a change in the major oceanic currents, resulting warm water being redirected into previously cooler areas. . It would change the nature of many ecosystems. If species could not migrate quickly enough to a new,appropriate habitat or adapt quickyl enough to the changed conditions in their current habitat, they could become extinct. . Change in global rainfall patterns could result, with all extra water in the seas, there would be more evaporation from the surface, and so more rainfall in most areas. . Changes in agricultural practices would be a must as some pests become more abundant. Higher temperatures might allow some pests to complete their life cycles faster.

Causes . Burning coal, oil and natural gas. These currently add over 30 billion tonnes of carbon dioxide to the atmosphere every year. . Manufacturing cement. This adds f…urther carbon dioxide to the atmosphere. . Deforestation. This returns to the atmosphere as carbon dioxide carbon that had effectively been locked up for thousands of years . Farm management. The major issue is the production of methane by sheep and cattle. Consequences . Higher average global temperatures . More prolonged droughts . More frequent severe floods . More intense storm activity . Rising sea levels . Coastal inundation and erosion . Loss of habitat for wild animals . Loss of food production . Displacement of populations from low lying areas in parts of China, Bangladesh, the United Kingdom and some Pacific Island nations. . Economic losses . Higher insurance premiums . Heat waves and health problems
There are only about 3 possible factors that could cause globalwarming: . Anthropogenic (man-made, e.g., burning carbon fuels,deforestation, increasing the greenhouse effect…); . Natural cyclical climate variations; and . Cyclical increase in solar output. . Of these, scientists have found that only the first iscausing global warming. . The second factor takes many thousands of years to changeclimate. . The third: there has been no increase in solar output over thelast century, in fact, the opposite is true. .
Climate change could cause sea level rise so that a small Pacific Island country, Kiribati, could go underwater, and all the population of more than 100,000 would have no home…s, no stores, no government and no country!
Potential outcomes predicted because of global warming: . Rising sea levels - this has already begun, with sea levels rising be 20 centimetres over the twentieth century and…, on the most recent data, predicted to rise by another 90 to 150 centimetres over this century. Although this appears to be a small rise in sea level, it will have a devastating effect on the littoral zone, beaches, coastal communities and some Pacific Island nations. . Food shortages, as some areas experience devastating floods, while others experience prolonged droughts . Loss of biodiversity - species extinction . More frequent and more severe extreme weather events
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 temper…atures 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.
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 rec…ord for the entire globe. It is true to a level of confidence between 97 and 99 per cent thatglobal warming is caused by greenhouse 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.
Glaciers melt witch raises sea level risks for everybody.
The possible reason for global warming, indeed, the reason thatjust about all climate scientists agree is causing it, is theburning of fossil fuels (coal, oil and natural gas)… in industry,transport and the generation of electricity. This emits carbondioxide (CO2), a greenhouse gas that is holding extra heat in theatmosphere.
Reduction in secondary pollutants is not a possible consequence ofglobal warming.
Sea levels will rise, causing floods
reduction in secondary pollutants
We can't tell the future, and we don't know if governments will beable to act before it's too late, but if global warming continuesunchecked it could mean that most life on ea…rth will end. Other people hope that the goals that all countries of the worldhave set in the Paris Climate Agreement will be enough to keepwarming to less than 3 degrees Celsius. Even if we manage that,millions of people will die.
