The detailed causes of the recent warming remain an active field of research, but the scientific consensus is that the increase in atmospheric greenhouse gases due to human activity caused most of the warming observed since the start of the industrial era. This attribution is clearest for the most recent 50 years, for which the most detailed data are available. Some other hypotheses departing from the consensus view have been suggested to explain most of the temperature increase.
One such hypothesis proposes that warming may be the result of variations in solar activity. We can just imagine how much of this heat would come from the environmental pollution as the toxic wastes emitted by factory chimneys, production of plastics, chemicals from hairsprays and the like. These innovations that are both detrimental to human health and environment, especially in times where we have denuded green fields and lack of the maintaining and sustaining of the forestry.
The current times would show much indifference from the human population who as learned to embrace the short term aesthetic beauty and comfort that this modernism offers to the industry. This apathy should then be addressed immediately especially at these times when the grave effects and destructions of the global warming are so imminent not only in the human health but most especially with the dwindling of natural resources.
Despite the notable efforts of some groups and organizations, one cannot help the passive undertaking of such a serious matter by the higher percentage of the human population. One should realize the horrendous effects that could follow with further negligence to such an alarming state of nature. The anticipated shift of climate because of global warming has the biggest possibility of having irreversible effects at both the continental and global scales which prove to be truly devastating.
Though the actual materialization of such projected effects remain controversial, the foreseen outcomes include the impeded ocean circulation which is responsible for the transportation of the warm water to the North Atlantic, The wiping out of Greenland and West Antarctic Ice Sheets, intensification of droughts, the wildfires out of heatwaves, severing storms, the speeding up of global warming brought about by the carbon cycle feedbacks in the terrestrial biosphere, and the exhaust of the terrestrial carbon from permafrost regions and methane from hydrates in coastal sediments.
The United States National Academy of Sciences has warned, Greenhouse warming and other human alterations of the earth system may increase the possibility of large, abrupt, and unwelcome regional or global climatic events. . . . Future abrupt changes cannot be predicted with confidence, and climate surprises are to be expected. It was stated that most of the consequences of global warming would result from one of three physical changes: sea level rise, higher local temperatures, and changes in rainfall patterns.
Sea level is generally expected to rise 18 to 59 cm (7. 1 to 23. 2 inches) by the end of the century. The extreme weather caused by global warming could lead to effects as that of Extratropical storms which is partly dependent on the temperature gradient that is predicted to weaken in the northern hemisphere as the polar region warms more than the rest of the hemisphere.
Because of the warm climate there would be an increase in the evaporation which will then cause heavier rainfall as our world is a closed system, which further leads to erosion. This is very detrimental to tropical areas which may lead to desertification due to deforestation. It was then predicted to have an average of 2. 8% catastrophic storms in every 1% increase in annual precipitation.
RESOLUTION Because of this awareness on the projected negative effects of global warming it has brought much concern to the human population which brought certain political advocacies into the proposition of ways to eradicate and alleviate the status of our ecosystem as greatly affected by the global warming. They are now promoting extensive means and way into advocating the social awareness of such horrendous effects to our world.
The effects and consequences of present acts my not be super visible or flatly exposed to the human eye, but the projected image of how bad things can turn out to be is now shown through studies such as that of one as reported to UN by Stephen Mwakifwamba, national coordinator of the Centre for Energy, Environment, Science and Technology with regard to the Tanzanian governments climate change. In the past, we had a drought about every 10 years, he says. Now we just dont know when they will come. They are more frequent, but then so are floods. The climate is far less predictable.
We might have floods in May or droughts every three years. Upland areas, which were never affected by mosquitoes, now are. Water levels are decreasing every day. The rains come at the wrong time for farmers and it is leading to many problems. Greg Holland, director of the Mesoscale and Microscale Meteorology Division at the National Center for Atmospheric Research in Boulder, Colorado, said on April 24, 2006, The hurricanes we are seeing are indeed a direct result of climate change, and that the wind and warmer water conditions that fuel storms when they form in the Caribbean are, increasingly due to greenhouse gases.
There seems to be no other conclusion you can logically draw. Holland said, The large bulk of the scientific community say what we are seeing now is linked directly to greenhouse gases. The Association of British Insurers has stated that limiting carbon emissions would avoid 80% of the projected additional annual cost of tropical cyclones by the 2080s. The cost is also increasing partly because of building in exposed areas such as coasts and floodplains.
The ABI claims that reduction of the vulnerability to some inevitable effects of climate change, for example through more resilient buildings and improved flood defenses, could also result in considerable cost-savings in the long term. Most national governments have signed and ratified the Kyoto Protocol aimed at reducing greenhouse gas emissions, but there is ongoing political and public debate worldwide regarding what, if any, action should be taken to reduce or reverse future warming or to adapt to its expected consequences.
All of these warnings and plans can only be fully realized once each and every individual take a serious look at this alarming earth condition; then personally taking the initiative to involve them selves and act in ways to the promotion of lessening all these harmful sources of global heat. We can take a start from the use of earth-friendly materials such as the recycling method or even the use of healthy vehicular fuels.
There are numerous ways to make use of the available alternatives or probably to explore new and better ways of catering materials for human services left to be seen.
