In popular discourse, emotions, particularly fear, play a more prominent role. Regional climates will change as well, but in very different ways. First, they scatter and absorb solar and infrared radiation and, second, they may change the microphysical and chemical properties of clouds and possibly their lifetime and extent. The quick rise or increase in temperature may lead to the death of trees in large scale because the trees are sensitive to the temperature stress. Fig3: concentration of methane Also See: 3. Sea levels are rising due to thermal expansion of the ocean, in addition to melting of land ice.
There is an estimation that, for every rise in temperature there will be a reduction of 5% in the yield of rice crops in South East Asia. The average global air temperature rose between 0. Vulnerability to weather disasters depends on the attributes of the person at risk, including where they live and their age, as well as other social and environmental factors. This phenomenon is called as global. . . Global Warming PowerPoint Template is a dark template for PowerPoint presentations on global warming and climate change presentations.
Global dimming, a phenomenon of increasing atmospheric concentrations of man-made aerosols, which affect cloud properties and block sunlight from reaching the surface, has partially countered the effects of warming induced by greenhouse gases. Some regions like parts of Northern Europe or West Africa will probably get wetter, while other regions like the Mediterranean or Central Africa will most likely receive less rainfall. . Global warming occurs due to the increase in the gasses of a greenhouse. The troposphere has a thick layer of carbon dioxide and this layer of carbon dioxide serves as a roof of the greenhouse described above.
Scientists have spent decades figuring out what is causing Global Warming. In some regions, changes in temperature and precipitation are projected to increase the frequency and severity of fire events. Other effects of global warming include higher or lower agricultural yields, further glacial retreat, reduced summer stream flows, species extinctions. Thanks to the World Wide Web, the speed of information being exchanged is made in real time opting for educational institutions to make use of this opportunity by providing a virtual learning environment to help reach and educate students from around the world. In this lecture, I start with the oxygen catastrophy and Earth's first ice age as an illustration of how changing the atmosphere can completely alter the climate of the Earth and the life it supports. It is not possible to state that a certain gas causes a certain percentage of the greenhouse effect, because the influences of the various gases are not additive. The coast can also be considered a region.
Tags : PowerPoint is the world's most popular presentation software which can let you create professional Global Warming powerpoint presentation easily and in no time. People like to fund things they know will work. National Oceanic and Atmospheric Administration. Browse by Genre Available eBooks. . The scientific community believes that climate like Global Warming have occurred throughout Earth's history and will continue to occur in the future. .
During present state, atmosphere system of our planet maintains a balance in taking of solar radiation by emitting radiations of infrared in the balance. Test questions: Available for purchase at the environmental science. Not only the temperature but also the amount of rainfall will be disturbed due to it. The rise in temperature will be more in the regions of higher latitudes and middle latitudes. . . This global warming ppt presentation for students,presenters,educationist and others available for free download global warming ppt presentation.
Global warming as we know is an increase in the temperature of Earth's atmosphere. . Also see our collection of. Most of the observed temperature increase since the middle of the 20th century has been caused by increasing concentrations of greenhouse gases, which result from human activity such as the burning of fossil fuel and deforestation. The layer of carbon dioxide allows the rays of a sun. Tags: , By: 17742 Views 72 months ago. .
Forest and bush fires cause burns, damage from smoke inhalation and other injuries. The major natural greenhouse gases are water vapor, which causes about 36-70% of the greenhouse effect on Earth not including clouds ; carbon dioxide C02, which causes 9-26%; methane, which causes 4-9%, and ozone, which causes 3-7%. The internet reduces the world into one global community. Hot days, hot nights and heat waves have become more frequent. There are three major ways in which global warming will make changes to regional climate: melting or forming ice, changing the hydrological cycle of evaporation and changing currents in the oceans and air flows in the atmosphere. Major storm and flood disasters have occurred in the last two decades. The effects of climate change to date have been small, but are projected to progressively increase in all countries and regions.
. . And unfortunately, we are currently destroying some of the best known mechanisms for storing that carbon—plants. . Jones English Teacher, Chengdu, Sichuan, China B. Global Warming and Climate Change Lecture Powerpoint Global climate change is a huge topic, and a difficult one to make students fully grasp the importance of. It is also immediate, it is happening now.
In such cases, the regional effect may be disproportionate and will not necessarily follow the global trend. . This activity will cause a wide-spread transformation in the patterns of precipitation due to the transformed pattern of air mass movements. In other cases, a change may be related to a change in a particular ocean current or weather system. The global warming is shifting the ranges of temperature and this will disturb the altitudinal distribution pattern and latitudinal distribution pattern of various organisms. The food productions will affect due to global warming than any other effects of greenhouse gasses. In his pursuit of comforts of life he ignored the threat of pollution and environmental degradation caused by industrialization.
