森林砍伐导致全球变暖和气候变化
作者(年代):Bhartendu Ajay森林砍伐砍伐和燃烧树木的行为在一个区域。土壤侵蚀是造成大范围的森林砍伐。砍伐森林对全球变暖的贡献,通常被视为一个温室效应增强的主要原因。它可以占人为二氧化碳排放总量的三分之一。最近的研究结果表明,二氧化碳排放由于森林砍伐贡献了约12%的人为二氧化碳排放从6 - 17%不等。枝条和其他植物移除大气中的碳以二氧化碳的形式过程中光合作用,释放氧气到大气中。衰变和燃烧木材释放这些存储的碳回到大气中。砍伐森林会导致土壤碳储存在被释放。在砍伐森林地区,土地升温更快,达到高温导致局部向上运动,提高云的森林,最终产生更多的降雨。生产排放的热带森林砍伐。 REDD, has emerged as new potential to complement ongoing climate policies. Global warming refers the rising average temperature of earth’s atmosphere and oceans. Climate model projections are summarized in 2007. Fourth Assessment Report (AR4) by IPCC indicates that during 21st century the global surface temperature is likely to rise a further 1.1 to 2.9ºC (2 to 5.2ºF) for their lowest emission scenario and 2.4 to 6.4ºC (4.3 to 11.5ºF) for their highest. The ranges of these estimates arise from the use of models with differing sensitivity to Green house gases (GHG) concentrations. GHG can stay in the atmosphere for an amount of years ranging from decades to hundreds and thousands of years. Five deadliest effects of global warming are: (i) Polar ice cap melting, (ii) Economic consequences, (iii) Increased probability and intensity of droughts and heat eaves, (iv) Warmer waters and more hurricanes and (v) Spread diseases. Government of India and Indian citizens have cautiously to take preventive measures otherwise A. Bhartendu: Deforestation 1732 Causing Global Warming and…. places and famous towns of India like Mumbai, Goa, Kolkata, Puri, Vishakhapatnam, Chennai, Pondicherry etc., are, very soon, going to be under water due to the effects of global warming. Forest are able to extract carbon dioxide and pollutants from the air, thus, contributing to biospheres stability.
