全球变暖在印度上下文及其因果关系
作者(年代):s . k . Bhartiya和b k。乔杜里全球变暖指的是地球的大气和海洋平均温度上升,增加在19世纪晚期开始,预计将持续上涨。如果我们走了20世纪的场景与全球变暖,自本世纪初期,地球表面的平均温度已经上升了1.4 F即0.8摄氏度。这一发现,约有三分之二的增加出现自1980年以来。变暖的气候系统是明确的和科学家都超过百分之九十,其中大部分是由人类活动产生的温室气体浓度增加,如森林砍伐和燃烧化石燃料。美国国家科学院也认出了这些发现。全球温度的增加将导致海平面上升,降水变化量和模式和可能的亚热带沙漠的扩张。如果全球平均温度增加4度高于工业化前水平,适应对自然系统的限制将在很大程度上被超过。因此人类生计所依赖的生态系统服务将不会被保留下来。全球变暖的影响在印度不同淹没低洼岛屿和沿海土地在印度喜马拉雅冰川的融化,威胁着许多人的体积流率最重要的印度的河流。全球变暖显示了一些最致命的影响。 Polar ice caps melting due to global warming will raise sea levels. Ice caps will throw the global ecosystem out of balance. Temperature rises and changing landscapes will endanger several species of animals. If Ice caps melt, the only reflector is the ocean; darker colours absorb sunlight, further warming the Earth. Anthropogenic global warming has economic consequences. Due to global warming, there is increased probability and intensity of droughts and heat waves. As the temperature of oceans rises, so will the probability of more frequent and stronger hurricanes. In future, towns of India like Mumbai, Chennai etc. may be covered with water due to global warming as such towns are situated on the bank of sea. As a consequence of this, the population of the country will decrease.
