Global warming essay: causes, effects & solutions introduction global warming is a phenomenon due to which the temperature of the earth’s surface land, water, and atmosphere, is rising year-by-year due to many natural and human-made causes. Land degradation is being eyed as one of the contributing factors of global warming by definition, it is the loss of the land productivity that could be permanently or temporarily (stocking & murnagham, 2000.
Besides global warming of 15ºc (sr15), the ipcc will finalize two other special reports in august and september 2019 respectively: climate change and land: an ipcc special report on climate change, desertification, land degradation, sustainable land management, food security, and greenhouse gas fluxes in terrestrial ecosystems (srccl. Deforestation is a contributor to global warming, and is often cited as one of the major causes of the enhanced greenhouse effect tropical deforestation is responsible for approximately 20% of world greenhouse gas emissions [37. Since 2006, when land degradation became a focal area, the gef has invested more than us$876 million in resources for at least 190 projects and programs that encourage use of sustainable land management practices (slm) to support national and regional development priorities.
