first pretend to know physics before proceeding to the video don't forget to like comment share and subscribe Enjoy watching [Music] The first discussion of the material is the understanding of global warming 2 causes of global warming 3 effects of global warming 4 ways to overcome global warming the first understanding of global warming Global warming is an imbalance of the earth's ecosystem due to the process of increasing the average temperature of the sea and land atmosphere on earth. Global warming is a process characterized by an increase in the temperature of the sea and land atmosphere. -Different [Music] The group of natural gases that naturally keep the temperature of the earth's surface warm are called greenhouse gases which include water vapor and carbon dioxide. The greenhouse gases that increase the most are methane, nitrogen oxides and CFCs, in fact these gases function to regulate temperature. the earth's surface to stay warm to live in but if there are more and more, more infrared radiation will be emitted towards the earth's surface and causes the earth's surface temperature to increase, the average temperature of the earth's surface has increased 0.74 + 0.18 degrees for 100 last year the high PCC or Inter governor panel of Finance stated that the increasing concentration of greenhouse gases was caused by human activities originating from carbon dioxide which is the result of emissions from burning fossil fuels . waste which contributes to greenhouse gas emissions by 3% industry 29% Housing 11% offices 7% transportation 15% agriculture 7% energy providers 13% and land use or conversion of forest land by 15% [Music] 2 causes of global warming [Music] which first, the energy consumption of fossil fuels, fossil fuels contain carbon, so carbon burning must produce greenhouse gases, namely carbon dioxide [Music], a greenhouse gas that is discharged into the atmosphere is related to lifestyle and population. For example, leaves, vegetables, fruits, paper and wood. Organic waste produces greenhouse gases, namely methane. It is estimated that 1 ton of organic waste produces 50 kg of methane gas. 3 Forest damage. One of the functions of plants is to absorb carbon dioxide and convert it into oxygen. Carbon dioxide is a greenhouse gas, so damage means the loss of the carbon dioxide greenhouse gas absorbing factor in the atmosphere with forest destruction of course the absorption of carbon dioxide is not optimal so that it will accelerate the occurrence of fourth global warming agriculture and animal husbandry the agricultural sector contributes to the increase in greenhouse gas emissions through rice fields which are famous for producing gas methane Use of fertilizers burning plant residues and decomposing agricultural residues livestock sector greenhouse gas emissions through animal manure livestock greenhouse gas emissions include 9% carbon dioxide 37% methane gas nitrogen oxides and ammonia Causes of acid rain [Music] 3 effects of warming global [Music] the first climate is unstable scientists predict that during global warming the northern regions of the northern hemisphere will warm more highly than the rest of the earth [Music] as a result the icebergs will melt and the land mass will decrease in seasons planting will be longer in some areas the temperature in winter and at night will tend to increase warm areas will become humid because a lot of water evaporates from the oceans high humidity will increase rainfall In addition water will evaporate faster from the ground as a result the areas will be drier than before [Music] the winds will blow stronger and maybe with a different pattern Typhoons that derive their strength from the evaporation of water will become bigger and thus the weather patterns will become more unpredictable and more extreme 2 sea level rise as the atmosphere warms the water the surface of the sea water is also warming, which means that the volume of water in the oceans is increasing due to expansion, thereby raising sea levels [Music] The melting of the Polar Regions causes the volume of sea water to increase, the impact will be an increase in sea level which may submerge part of the land [Music] 3 people's agriculture think a warmer earth will produce more food than before but this is not the case in some places [Music] for example Canada benefits from longer growing seasons on the other hand tropical farmland will be semi dry in some parts of Africa it may not be arable 4 the life of wild animals and plants animals and plants find it difficult to avoid the effects of global warming because most of the land has been controlled by humans as a result of global warming animals tend to migrate towards the poles or mountains to seek cooler areas plants will change their direction of growth looking for new areas because of their old habitat getting too warm but human development will hinder this movement which could lead to the extinction of some animals five human health rising global temperatures have led to many heat related diseases and death such as stress stroke and cardiovascular disorders [Music] DHF and malaria are also expanding territories The cause of the longer attack and transmission is the increasing temperature of subtropical areas which allows the development of pathogens in the area. The fourth way to overcome global warming is the first, environmental competition by reforestation, planting trees and carrying out critical land afforestation. wind solar water and bioenergy two ways To reduce the use of fossil fuel energy and the third is to do recycling and energy efficiency as well as efforts for the wider community by providing understanding and application to prevent global warming [Music] [Applause] [Music] [Applause hand]
