Global Warming; It’s Effects

Global warming is a phenomenon where the earth’s average temperature raises due to increased amounts of greenhouse gases; greenhouse gases such as carbon dioxide, methane and ozone trap the incoming radiation from the sun. It occurs when carbon dioxide and other air pollutants collect in the atmosphere and absorb sunlight and solar radiation that have bounced off the earth’s surface.
There are several reasons behind this global warming and the biggest causes are deforestation, factories, electricity wastage, etc. Deforestation reduces the number of trees, which means there will be more carbon dioxide in the air. Factories produces a lot of greenhouse gases and the most electricity requires burning fossil fuels.

There are diverse effects of global warming in our live environment. It is about to cause huge ruination over the time. It is going to leave very serious and alarming effects on our life and habitat. More frequent and intense drought, storms, heat waves, rising sea levels, melting glaciers, and warming oceans can directly harm animals, destroy the places they live, and wreak havoc on people’s livelihoods and communities. More specific consequences are depicted bellow:

1. Climate Change: Irregular weather patterns are already started showing results. Increased precipitation in the form of rain has already been noticed in polar and sub-polar regions. More global warming will lead to more evaporation which will cause more rains. Animals and plants can not easily adapt to increased rainfall. Plants may die and animals may migrate to other areas, which can cause the entire ecosystem out of balance.

2. Raising sea levels: Due to global warming it is increasing ocean temperatures which is creating melting glaciers and ice caps all over the world. Melted ice increases the volume of water in our oceans. Warmer temperatures also result in the expansion of the water’s mass, which causes sea level to rise, threatening low-lying island and coastal cities.
3. More frequent and intense extreme weather events: Extreme weather events like brushfires, cyclones, droughts and floods are becoming more frequent and more intense as a result of global warming.

4. Heavy downpours: Effects of global warming has been introduced heavy downpours, changing precipitation and heavy rain is increasing nationally, specially over the last 30 to 50 years.

5. Floods: As warmer temperatures cause more water to evaporate from the land and oceans, changes in the size and frequency of heavy precipitation events may in turn affect the size and frequency of river flooding.
6. Drought
: while some parts of the world may find themselves deluged by increasing storms and raising waters, other areas may find themselves suffering from drought. As the climate warms, expert estimates drought conditions may increase rapidly over the time. An increase in drought conditions lead quickly to shrinking water supply and a decrease in quality agricultural conditions. This puts global food production and supply in danger and leaves population at risk for starvation.
7. Disease
: Warmer temperatures along with associated floods and droughts are encouraging worldwide health threats by creating an environment where mosquitoes, ticks, mice and other disease- carrying creatures thrive.

8. Oceans are warming and acidifying: The oceans have absorbed most of extra heat and carbon dioxide so far- more than the air- making the seas both warmer and more acidic. Warming waters are bleaching coral reefs and driving stronger storms. Rising ocean acidity threatens shellfish, including the tiny crustaceans without which marine food chains would collapse.

9. Animal migration and Extinction of species: Some animals have already faced extinction due to global warming and climate change, such as the golden toad that disappeared because of drought and other climatic changes. Up to half of planet and animal species in the world’s most naturally rich areas like the Amazon and Galapagos islands could face extinction by the turn of the century if carbon emissions continue to rise.

10. Increase of health issues and cost: Global warming also puts human health at risk. Areas that experience wild fires and severe drought conditions suffer from reduced air quality that result in respiratory and cardiovascular hospitalizations for lung illness, bronchitis and other breathing problems.

11. Impacts on agriculture and food supply: Experiencing more severe droughts and floods, agriculture becomes more challenging, threatening our food security. Climate change and global warming will make it more difficult to grow crops, raise animals, catch fish in same ways and places that we have before.
12. Impacts on energy: Changes in temperatures, precipitation and sea level and how often severe extreme events take place will affect how much energy we consume and produce. Since we rely on energy so heavily for modern life, it is important that we consider the long-lasting effects that global warming plays on our access to energy. In warmer climate, we will use more electricity for air conditioning. This is how the demand for energy used for cooling will increase, while the demand for energy used for heating will decreased. This will affect greenhouse gas emissions, but the net effect will depend on which energy sources are used for electricity and heating. A warmer climate might also reduce the efficiency of power for many existing fossil fuel and nuclear power plants because these plants’ equipment need to maintained at certain temperatures to function safely. The colder the water used to cool this equipment, the more efficient the generator will be. So if higher air and water temperatures occur, the efficiency of these plants converting fuel into electricity will be reduced.
13. Economic consequences: The cost associated with climate change raise along with the temperatures. Severe storms and floods combined with agricultural losses cause billions of dollars in damages and money is needed to treat and control the spread of disease. Economic considerations reach into nearly every facet of our lives.
Consumers face raising food and energy costs along with increased insurance premiums for health and home. Governments suffer the consequences of diminished tourisms and industrial profits, soaring energy, food and water demands, disaster clean up and border tensions.

14. Conflicts and war: Declining amounts of quality food, water and land may be leading to an increase in global security threats, conflicts and war.

15. Poverty: The increased frequency and intensity of extreme weather events like hurricanes, wildfires, and droughts threaten lives in this front-line communities, driving people from their homes and jeopardizing food sources and livelihoods. All these effects increase the likelihood of conflict, hunger and poverty.

All of those are how global warming is creating threats for human and environment over the time. This is a crucial concept for all over the world. World is getting a dangerous position due to the harmful effects of global warming. Our life and existence is going to be in risk due to global warming. It is related to all aspects of our life; thus, we human being should take all necessary steps, so that it will leave very small effects on our life and lives.
