'Climate Change Paper Essay\r'

' global climate shift is one of the most urgent environmental problems we pull in to acknowledge today. The mankind, as we have observed and enter data over the last several decades, is in the midst of an unexpected alteration. Temperature in the winter period is changing more than some other lenifys and mid to noble latitude positions are showing comparatively queen-sized changes than those of low latitudes. The water vapor, carbon dioxide, ozone and many other chemical compounds in the atmosphere which absorb caloric radiation emitted by landed estate’s prove and atmosphere, are increasing, contributing to the signifi preservet changes in our ball-shaped climate.\r\nOver the past one hundred years, Earth’s average surface temperature has increase by approximately 0.74 degrees Celsius and for the past 16 years from 1995-2010, 15 of those years were among the warmest years in the instrumental demonst p evidence of global surface temperatures since 1850. (IPCC, 2007) It has been shown that since the start of the Industrial Revolution, atmospheric carbon dioxide concentrations have risen exponentially and steady as a result of the combustion of fogey fuels as an energy source for industrialized nations and ontogeny nations a bid. unconnected from that, deforestation also play a major role in global thawing as forested lands are typically unclouded and burned for farming.\r\nThe sea levels have as a result of the associated thermal expansion of ocean water and melting of glaciers, shown to rise at a rate of 1.8 millimeters per year in the past century. A rise in sea levels give have sober implications on coastal environments or small islands from the perspectives of twain natural ecosystems and human populations as a man-sized portion of the human population live in coastal areas. There would be direct inundation of low-lying wetlands and dryland areas, increased salinity of estuaries and aquifers, heightened storm surges and floods.\r\nApart from that, changes in the global climate patterns will worsen an already increasing problem of feeding the world population, which is predicted to increase to approximately 9 billion from the present-day(prenominal) 7 billion by 2050. Dominant nourishment crops like corn, rice, wheat, are likely subjected to abnormal changes in temperature and moisture that control growth, survival, and reproduction. Shifts in the geographic hunt down of some crop species may result in signifi whoremongert changes in regional land aim patterns that come with social and potentially hefty scotch costs. According to a major study conducted by the Environmental interchange Unit at Oxford University which carried let on a collaborative study with agricultural scientists from 18 countries to examine the regional and global implications of climate change, in that respect would be an up to five percent reducing of global production of cereal crops and the current discriminat ion in cereal crop production betwixt authentic and developing countries will be elongated further.\r\nResults of the study, in general, showed that agricultural production in developed countries, which are mostly located in the moderate regions, would increase while agricultural production in developing countries as a whole, would decrease by approximately ten percent, exacerbating the widespread aridness issue common in those countries. As culture shifts polewards, plant growth and production would be by and large affected by changes in the distribution of pelting and the increase of ultraviolet radiation, and aggravated problems of salinity, erosion, and desertification. Extreme climatical events would also occur more frequently. Warmer temperatures may cause some crops to grow faster than familiar and reduce yields during the summer time when the temperature goes above the optimum growing temperature.\r\nAside from that, more extreme last events like floods and droughts with extreme temperature and precipitation changes can anticipate cereal crops from yield at all. Take for instance, in 2008, the Mississippi River flooded just prior the harvest period for several crops, resulting in a spacious loss of revenue for farmers. Also, pests, weeds and fungi raise by a warmer climate would overcompensate to proliferate and build up resistance through and through sexual recombination, to pose an even greater curse to current domesticated crop varieties. Many pest, weeds and fungi thrive under warmer, wetter climates with increased carbon dioxide levels. Currently, farmers spend billions of dollars every year to flake these threats and with the changes in climate, it is predicted that the ranges of weeds and pests are likely to magnify northward, potentially creating new problems for farmers’ crops previously unexposed to these species.\r\nIn set out to combat climate change from an agricultural standpoint, farmers can adapt by adjusting pl anting patterns, practice smut management techniques in response to the changing live on patterns. There are various methods like condition and strip cropping and no-till” reduced tillage that can service of process prevent soil loss due to lead-in and water erosion. Similarly, farmers could consider planting trees and shrubs for the purpose of providing drift barriers to reduce soil erosion. Apart from that, crop rotations like the planting of corn for a growing season and soybean the next growing season, limits the likelihood that pests can proliferate and potentially reduce use of northward fertilizers.\r\nFarmers could also apply manure or leguminous cover crops in place of chemical fertilizers. part such methods are useful to combat climate change, some of the methods may not be feasible in certain areas and even if they are feasible, the yields will not necessarily match the amount of formulaic farming.\r\nAs the climate changes, the demand for Federal adventur e management programs may increase and farmers could potentially direct in the development of droughttolerant varieties and even consider biotechnology. genetically modified crops, made for the purpose of higher yields and brusque to no use of chemicals, may potentially diverge the effects of climate change to a large extent if it is easily made and widely implemented. Unfortunately, in that respect are limitations in each technology and it takes a variety of ecosystems to make changes that will cause a significance, in reducing the impact of climate change.\r\nReferences\r\nJones, R., Ougham H., doubting Thomas H., Waaland S.
