GLOBAL WARMING
Definition of Global Warming
along with the increasing temperature of the earth in the world , then we need to provide information that is essential to all communities that exist throughout the world to find a very large negative impact as a result of global warming . so let us think together after skimming the information about global warming and its impacts to our planet .
Global warming is the increase in the average temperature of the atmosphere , ocean , and land earth caused by several factors . most likely caused by increased concentrations of greenhouse gases resulting from human activity through the greenhouse effect global warming will be followed by Climate Change , such as increased rainfall in some parts of the world , causing flooding and erosion . Meanwhile , in the other hemisphere will experience a prolonged dry season caused by rising temperatures.
Causes of Global Warming
Greenhouse Effect
All energy sources that exist on Earth comes from the Sun . When this energy arrives Earth 's surface , the light turns into heat that warms the Earth . Earth's surface will absorb some of the heat and reflect repopulating the rest . Some of this heat tangible long-wave infrared radiation into space . Some of this heat tangible long-wave infrared radiation into space . However, some of the heat remains trapped in Earth's atmosphere as a result of accumulated amount of greenhouse gases include water vapor , carbon dioxide , and methane that trap this radiation. These gases absorb and reflect radiation emitted waves heat the Earth and consequently will be stored on the surface of the Earth . This situation occurs continuously , resulting in an annual average temperature of the earth continues to rise . These gases serve as the gas in the greenhouse. With the increasing concentration of these gases in the atmosphere , the more heat is trapped beneath it .
Feedback Effects
Feedback process that occurs affects of global warming . An example is the process of water evaporation . In the case of warming due to increasing greenhouse gases such as CO2 , initially warming will cause more of water to evaporate into the atmosphere . Because water vapor is itself a greenhouse gas , warming will continue and increase the amount of water vapor in the air until it reaches equilibrium with the water vapor concentration . The resulting greenhouse effect greater than the effect of CO2 alone . ( Although this feedback increases the absolute water content in the air , the relative humidity of the air is almost constant or even decreases slightly because the air becomes warmer ) . This feedback effect only slowly as CO2 has a long time in the atmosphere .
Another important feedback is the loss of reflectance ( albedo ) of ice. As global temperatures increase, ice near the poles melts at an increasing rate . Along with the melting of ice, land or water below it will open . Both land and water has the ability to reflect light much less when compared to ice , and consequently will absorb more solar radiation . This will add to the warming and lead to even more ice to melt, causing a continuous cycle .
Positive feedback due to release of CO2 and CH4 from the softening of frozen ground ( permafrost ) are other mechanisms that contribute to warming . In addition, the melting ice will also release CH4 are also positive feedback .
The ability of oceans to absorb carbon will also be reduced when it warms up , this is caused by the decreased levels of nutrients in the mesopelagic zone thus limiting the growth of phytoplankton diatoms than a carbon sink that low .
Deforestation
Rampant cases of deforestation is one of the causes of global warming . Deforestation that reduces carbon sequestration by trees , causing the increase of carbon emissions by 20 % , and change the local micro-climate and hydrological cycle , thus affecting soil fertility . Forests are the lungs into the Earth now can not function to its full potential because it has a very reduced number of existing trees . The number of existing trees can not balance the number of CO2 on Earth .
Due to Global Warming
Unstable Climate Change
It has been predicted by scientists , the northern regions of the Northern Hemisphere will heat up more than other regions on Earth . This will result in the melting of icebergs and land will shrink . It would be a bit of ice floating in the waters . . Areas that previously experienced mild snow , probably will not experience it again . In the mountains in temperate regions, snow covered sections will shrink and will melt faster . Growing seasons will be longer in some areas . Temperatures in winter and at night will tend to increase.
Warm regions will become more humid as more water evaporates from the oceans . High humidity will increase rainfall , on average , about 1 percent for each degree Fahrenheit warming . Storms will become more frequent . In addition , the water will evaporate more quickly than soil . As a result, some areas will become drier than ever . The wind will blow harder and probably with different patterns . Hurricanes ( hurricane ) which draws its strength from the evaporation of water , will be greater . Contrary to the warming that happens , some very cold periods might occur . Weather patterns become less predictable and more extreme .
Rising Sea Level
When the atmosphere warms , the surface layer of the oceans will also warms , it expands and causes the volume will raise the sea level . Warming also resulted in the melting of the polar ice , especially around Greenland .
Changes in sea level will greatly affect the life on the beach . Some areas will sink . Erosion of cliffs , beaches and sand dunes will increase . Even the slightest rise in sea level will greatly affect coastal ecosystems , for example, would drown coastal marshes half .
Ecological disturbance
Animals and plants into living creatures that are difficult to avoid the effects of global warming because most of the land is controlled by humans . In global warming , animals tend to migrate toward the poles and up the mountains . Plants will change the direction of growth , seeking new areas as old habitats become too warm . However , human development will obstruct this movement . Species migrate north or south is blocked by the cities or farms may be dead . Some types of species that are not able to quickly move towards the poles may also be destroyed .
Some kind of way to lessen the negative impact of Global Warming
The damage that has occurred can be addressed in several ways . The beach area is protected by didnding and barrier to prevent the entry of sea water . As another way , the government helps populations in coastal areas to move to higher ground . There are two ways to slow the increase in greenhouse gases . First, it prevents the carbon dioxide released into the atmosphere by storing the gas elsewhere . This method is called carbon sequestration ( removing carbon ) . The second way is to reduce the production of greenhouse gases .
Other ways that can be done is as follows :
- Plant more trees
- Traveling with environmentally friendly vehicles , for example: bicycle
- Use energy saving electronics
- Reduce the use of air conditioning
- Recycling organic waste
- Separate Waste Paper , Plastic , and cans that can be recycled
