Project Report # 1. Meaning to Global Warming:
ADVERTISEMENTS:
The term “global warming” refers to the increase in the average temperature of global surface air and oceans since about 1950, and to continuing increases in those temperatures.
Greenhouse gases, being lighter than air, naturally rise up the outer limits of the earth’s atmosphere and then settle there, creating an impenetrable barrier that traps heat from being able to escape into space and warming the temperature.
Another term for “global warming” is “climate change”. The Intergovernmental Panel on Climate Change (IPCC) concludes that greenhouse gases are responsible for most of the observed temperature increase since the middle of the twentieth century, and that natural phenomena such as solar variation and volcanoes probably had a small warming effect from pre-industrial times.
Greenhouse gases are defined as “gaseous constituents of the atmosphere, both natural and anthropogenic, that absorb and emit radiation at specific wavelengths within the spectrum of thermal infrared radiation emitted by the Earth’s surface, the atmosphere itself and by clouds”.
Climate change is any substantial change in Earth’s climate that lasts for an extended period of time. Global warming refers to climate change that causes an increase in the average temperature of the lower atmosphere. Global warming can have many different causes, but it is most commonly associated with human interference, specifically the release of excessive amounts of greenhouse gases.
ADVERTISEMENTS:
Gases, such as carbon dioxide (CO2), methane (CH4), water vapour, and fluorinated gases, act like a greenhouse gases around the earth. This means that they allow the heat to come from the Sun into the atmosphere, but do not allow the heat to escape back into space. The more the greenhouse gases, the larger the percentage of heat that is trapped inside the earth’s atmosphere.
The earth could not exist in its present state (that is, with life) without the presence of some naturally occurring greenhouse gases, such as CO2, CH4 and water vapour. Without any greenhouse gases no heat would be trapped in atmosphere, so the earth would be extremely cold.
Naturally occurring greenhouse gases (non-fluorinated gases) are good in naturally occurring amounts; it’s when people start contributing excessive amounts of them that greenhouse gases become a problem. With excessive greenhouse gas buildup, the earth’s atmosphere warms to unnatural temperatures which causes, sea surface temperatures to rise, precipitation patterns to change etc.
The root cause of global warming is the emission of carbon dioxide due to burning of fossil fuels. The main culprits are for this the power plants that burn coal to produce electricity and in the process emit huge amounts of carbon dioxide. This carbon dioxide envelops earth and does not allow heat of the sun to escape into the atmosphere, giving rise to the temperature.
ADVERTISEMENTS:
Global warming is one of the most important issues of modern times and if not taken seriously, it is all set to annihilate all life forms from the surface of the earth. It is continuous increase in the average temperature of the air near the surface of earth and that of the oceans.
Global warming definition may look very simple but the phenomenon has started taking its toll, as the climatic conditions all over the earth are changing very rapidly.
Project Report # 2. Origin of Global Warming:
Global warming is the process, which started long and long ago. In order to understand when global warming began, we should look back for many and many years ago — in the times much earlier before human’s devised international treaties and even much earlier before we learned to burn first fossil fuel, which was wood.
ADVERTISEMENTS:
It was about the second half of the 20th century, when the global warming had become a talk of the town. In year 1997, the problem of global warming, or to be more exact the problem of human contribution into this natural phenomenon, was addressed officially, when the world’s largest industrialized countries agreed to reduce greenhouse gases emissions as the effort to stop the rapid progression of the global warming.
(i) Methane:
CO2 is not the only “Greenhouse Gas”. While carbon dioxide may be primary greenhouse gas, methane actually is 20 times more effective as CO2 at trapping heat in the Earth’s atmosphere. Emissions of methane released into our atmosphere have risen 145% in the last 100 years.
Methane naturally occurs as part of the biological processes behind everything from bovine flatulence to the organic bacteria and sulfur’s commonly found in bogs, springs and wells. Methane is a natural form of gas that is released in rice paddies as well as the composting and decomposition of organic matter. However, methane gas is also released during the processing and preparation of fossil fuels.
(ii) Water Vapour:
Water vapour is responsible for 2/3 of the heat currently trapped in the Earth’s atmosphere by all greenhouse gases. The hotter the atmosphere gets, the higher the level of “relative humidity” which holds the heat in even better.
(iii) Nitrous Oxide:
Nitrous oxide (N2O) is a colourless, non-flammable gas with a slightly sweet odour. Most commonly known as “laughing gas” and used as a medical anesthetic. Nitrous oxide is naturally produced by oceans and rainforests.
Nitrous oxide is naturally broken down in the atmosphere through chemical reactions that occur with sunlight. Some of the most prevalent “man-made” sources of nitrous oxide are agriculture fertilizers, nylon, catalytic converters and nitric acid, along with the burning of organic matter.
Project Report # 3. Causes of Global Warming:
Over the past century, our planet has slowly been warming up. Since the beginning of the 20th century, the average temperature around the world has gradually risen by one degree fahrenheit. Though this minimal warming might not seem so significant, but the over-all impact will most certainly prove to the devastating if this continual warming process is not somehow ebated.
So, the global warming may cause by both naturally and anthragogenically.
The issue of global warming is most often blamed on human beings’ ecologically irresponsible practices and technologies. In fact, global warming is quite a complex phenomena brought about not only by us but also by nature itself.
To the surprise of many environmentalists, in fact, mankind and technology actually aren’t the only significant causes of global warming. There are actually a wide variety of natural causes, ranging from volcanic eruptions, solar radiation and natural thawing of the Earths “permafrost” and glaciers.
In other words, the planet’s temperature, just like most other things in life and natural science, simply tends to fluctuate through natural, rhythmic, “ebbs and flows” and highs and lows that are caused and by sources within the planet itself, as well as the vacillating environment of the solar system and universe. Several “man-made” causes also play a significant role in global warming trend.
(A) Natural Causes of Global Warming:
(i) Forest Fires:
Among the most common and most significant contributors to global warming is deforestation caused by forest fires. Fires are natural occurrences in many forests as it is nature’s way to clear to up old growth to encourage new ones.
It also helps fertilize sprouting and existing trees and plants. However, new trees take much time to grow large enough to absorb large quantities of carbon dioxide and produce sufficient oxygen.
The fires also cause much carbon-filled smoke to rise from the forests to the atmosphere. Both results have dramatic effects on the rate at which global warming is currently occurring. Forest fires started by man, whether intentionally or not, pose even greater dangers to the atmosphere.
(ii) Oceans:
Oceans are also significant contributors to global warming as it naturally contains much polluting carbon due to the ecosystems they support. The top layers of oceans contain more pollution than the Earth’s atmosphere and much of that pollution rises. The amount of pollution and number of pollutants are also worsened by man, making oceans even greater contributors to global warming.
(iii) The north and south poles:
Both the North and South poles also contribute a lot to global warming. It is in those areas where permafrost contains large amounts of carbon that have frozen over time. Disturbances to these areas cause the permafrost to melt and release the pollutants into the atmosphere.
The carbon held within these lands have been out of the carbon cycle for thousands of years and so releasing them would cause an imbalance to natural processes.
(B) Man Made or Anthropogenic Causes of Global Warming:
(i) Power plants:
Nearly 40% of our carbon dioxide emissions come directly from the process of burning “fossil fuels” in order to generate electricity. Of that almost 40% of our CO2 emissions directly attributed to generating power, over 90% of it come from the burning of coal. Coal emits 25% more carbon per “unit of energy” than oil and 70% more carbon than natural gas.
(ii) Automobiles:
Approximately 1/3 of the carbon dioxide emissions released into our environment comes from the burning of gasoline in internal- combustion engines of automobiles, buses, motorcycles, recreational vehicles, trucks and motor sports.
As motor sports (racing) continue to grow in popularity, the huge amount of fuel being used continues to grow annually. Just NASCAR alone, which is only one of numerous racing associations, admits that it burns over 1 million gallons of gas per year which is used for the racing, trials, practice runs, etc.
That doesn’t even take into account the gas spent travelling, hauling the cars, equipment, team and tools for each car back and forth to the track.
(iii) Airplanes:
The United Nation’s Inter governmental Panel on Climate Change estimates that aviation currently is responsible for just under 5% of global warming and that the figure could very well rise to approximate 15% by the year 2050.
(iv) Buildings:
The regular maintenance, temperature control and cleaning of buildings structure actually account for nearly 12% of carbon dioxide emissions.
(v) Deforestation:
Deforestation is the 2nd most prolific cause of atmospheric CO2 influx. Deforestation is responsible for nearly 1/4 of all carbon emissions entering the atmosphere. The planet cuts and burns nearly 34 million acres of trees each year, including millions of acres of “rainforests”.
The process of deforestation is “doubly” dangerous for the planet, because not only millions of tons of carbon dioxide is added into the atmosphere each year, but also wiping out the most effective cleansers of that deadly CO2 gas, the trees and plants that naturally “thrive” by consuming the carbon dioxide and offering up pure, clean, breathable oxygen as a free byproduct of the plant life cycle.
(vi) Melting permafrost:
Permafrost is the frozen soil throughout the Arctic and sub-arctic regions, that contain all kinds of organic matter such as all kinds of frozen plants and animals that have been frozen solid and held inert for 30,000 years. Approximately 25% of the land mass of the Northern Hemisphere is “permafrost”, or soil with a temperature of 32 degrees Fahrenheit or less.
Permafrost has acted like a jail cell for carbon, methane and other greenhouse gases for several thousand years. As glacial regions and permafrost begin to melt, the 50 billion tons of carbon, that held inactive, under the frozen surface of the tundra, will begin and continue to be released into our atmosphere, creating a greenhouse effect that would make the residents of the hottest and most humid tropical islands faint in mere minute.
(C) Global Warming Due to Arctic Wildfires:
Incidences of massive wildfires in Arctic tundara pose a huge threat to the global climate. The 2007 blaze on the North Slope of the Alaska’s Brooks Mountain Range released 20 times more carbon to the atmosphere than what is annually lost from undisturbed tundra.
As wildfires increase in frequency and size along Alaska’s North Slope, it may release large amounts of the greenhouse gas CO2 to the atmosphere and accelerate the transformation of the frozen, treeless tundra of today into a different kind of ecosystem less capable of storing carbon. Together, the impacts could have profound implications on atmospheric carbon and climate.
In 2007 the Anaktuvuk River fire ravaged a 40-by-10 mile swath of tundra the largest ever recorded in the region. While the Anaktuvuk River fire scorched only upper soil layers that are about 50 years old, it caused the release of more than two million metric tons of CO2 to the atmosphere.
This amount is similar in magnitude to the annual carbon sink for the entire Arctic tundra biome averaged over the last quarter of the twentieth century.
Project Report # 4. Effects of Global Warming:
i. Effects of Global Warming on Polar Ice Caps:
The effects of global warming are strongest at the poles. Ice all over the world melting. This includes the ice of mountain glaciers, Arctic sea ice and ice sheets covering West Antarctica and Greenland. The melting ice increases the sea level and this causes flooding of low-lying areas. When snow and ice melts, their ability to reflect sunlight lost this accelerate the global warming even further.
Cities such as Venice are starting to sink. Small islands such as Guyana are also starting to becoming submerged. The sea level is estimated to have increased at a rate of 0.1 to 0.2 inches per year according to 2001 report.
Since 1900 global glacier surface area has decreased by half and glacial retreat is occurring on every continent. The effects include landslides, glacial lake overflow and flash floods as regular, seasonal patterns of snowfall and some melting are destroyed.
Less glacier melt-water in summer means the drying up of rivers and streams which are needed for drinking water, irrigation and many other processes. Just imagine the effects from an accelerated melting of Himalayan glaciers. The Ganges and other major rivers are the lifeblood for the huge populations of India, China and other parts of Asia.
The ice-sheets of Greenland and the West Antarctic are also melting at rapid rates. Since 99% of ice resides in Polar Regions, these huge amounts of fresh water will have noticeable impacts, contributing to rising ocean levels and disruption of the Gulfstream mechanism. Fisheries will be affected, rely on the cold water for breeding and food.
Although climate change is complex to predict, sea level is expected to rise between 28 cm and 79 cm (11 and 31 inches) by 2100. Floods will become more common in the future.
ii. Effects of Global Warming on Weather:
Precipitation in the form of rain and snow has on average, increased across the whole world.
Irregular weather patterns have an effect on humans. Rain is not only an inconvenience for humans, but also damage human property. The increase in heat will increase evaporation which is why there will be more rain.
Animals and plants cannot easily adapt to increased rainfall or snowfall and many animals migrate to other areas. Plants can die as a result and this can cause an ecosystem to collapse as plants are the main source of food in the ecosystem.
Hurricanes and other storms are likely to become stronger. Hurricanes form from simpler tropical storms oceans. The water from the warmer ocean evaporates and it heats the surrounding air, creating hurricanes. Higher temperatures mean that more water will evaporate creating stronger hurricanes.
More extreme weather is already occurring. Cyclones have gained in strength since 1970. Rainfall associated with such weather has increased by 7%.
Heavily populated, low-lying coastal areas in cyclone-prone areas are particularly vulnerable.
Up till 2004 hurricanes were strictly a North-Atlantic affair. Until Hurricane Katarina struck Brazil that year from the South Atlantic.
Already, in some African countries droughts and floods occur more frequently, and outside of previously known cycles. Higher evaporation rates will cause more rainfall in some areas, causing soil erosion and desertification of areas. In the future, Africa, the poorest continent, will be particularly hard hit by droughts and floods while having few resources to combat these.
Transport will be affected by cracking road surfaces, rupturing pipelines, railway lines and runways. Melting permafrost presents risks of road and rail- track subsidence.
Permafrost in Alaska, Russia and Canada is already melting. Billions of tones of methane gasses now locked in huge frozen peat bogs in Siberia.
The size of this frozen peat-bog is like the size of France and Germany combined.
iii. Effects of Global Warming on Food Production:
As temperatures around the world will increase, plants will find it harder to cope and they will die. Some of the plants are used by humans for food and so a food shortage may occur. Plants make their own food through the process called photosynthesis.
The enzymes that are needed for photosynthesis die when exposed to high temperatures. Pests may also migrate to new areas and destroy the crops there. Pests may migrate from tropical countries to temperature countries.
Agriculture would be severely affected because there is no water for plants to grow (due to higher temperature). When there are no plants, humans have nothing to eat. There are also no plants to feed animals and so humans cannot eat animals either. The high temperatures can also cause heat-strokes and other illnesses to humans. Droughts will become more common in coming time.
iv. Effects of Global Warming on Ecosystems:
Animals have been migrating to adapt to new conditions. Some butterflies, foxes and alpine plants have moved north to cooler areas.
This migration destroys ecosystems and their biodiversity. As parts of the food chain are lost from an ecosystem the whole ecosystem can easily collapse. Ecosystems and their biodiversity are important to humans. Humans get food, employment, raw materials and pharmaceutical products from the environment.
It is possible that symbiotic species (species that depend on each other) will become incompatible. Ecosystems will definitely change. So species will migrate to more suitable conditions while some will stay and try to adapt. Not all will succeed and more species will become extinct. It is predicted that 25% of all mammals and 12% of bird’s species will be extinct within the next 30 years.
v. Effects of Global Warming on Humans:
Rising temperatures have an effect on the health of humans. The world glimpsed this in 2003 when Europe was struck by heat waves and people died. Heat strokes are likely to increase as temperature gets hotter.
Diseases such as malaria are likely to spread. Parasites that originate in tropical regions may migrate to temperate regions as become warmer. Mosquitoes are an example and it is predicted that malaria will spread around world. It is also predicted that asthma will increase around the world as allergens that cause asthma will become more common.
Hurricanes have divesting effects on humans and their properties. Hurricane Katrina was famous hurricane for decimated the city of New Orleans, destroying structures, killing people and displacing.
vi. Effects of Global Warming on Oceans:
Between 1880 and 2000 a 20 cm. rise in ocean levels has been recorded — now occurring at 0.2 mm per year. This is due to ocean water expansion through its warming and water from melting glaciers and polar ice. Oceans have absorbed about half the human-made CO2 emissions since 1800. A higher CO2 content makes the oceans more acid. This has adverse effects on coral, fish and plankton.
Warmer ocean water and volumes of fresh water from melting glaciers could disrupt the Gulfstream which influences Northern European weather. A cooling effect could occur. Rising oceans cold swallow low-lying islands and coastal areas.
vii. Effects of Global Warming on Water Availability:
Reduced rainfall, droughts, and vanishing glaciers will severely reduce the availability of drinking water.
viii. Effects of Global Warming on Further Global Warming:
Melting glaciers and permafrost may be at a stage where there is no turning back. As they contribute their fresh water to the oceans and as methane gas is released these events will further accelerate global warming. This is called the positive feedback effect.
“Tipping points” is a delicate threshold where a slight rise in the Earth’s temperature can cause a dramatic change in the environment that itself triggers a far greater increase in global temperatures.
Huge deposits of methane are trapped in ice crystals under the oceans. If these would be released the atmosphere would experience sudden and significant further warming.
ix. Effects of Global Warming on Coral Reefs:
Corals get their food from an algae called zooxanthellae, which lives in the coral. This algae is extremely sensitive to temperature changes, and “an increase of just 1.8 degrees Fahrenheit can cause corals to expel their algae, or ‘bleach’. Over a prolonged period of time, bleaching leads to death.
A second contributing factor to the current sea-wide decline in coral reefs is that, as atmospheric concentrations of carbon dioxide (CO2) increasing oceans are becoming more acidic. This “reduces the availability of free carbonate ions in the water,” making it more difficult for the polyps that build coral reefs to extract the calcium carbonate they need to survive.
x. Effects of Global Warming on Animals:
To get a better understanding of global warming, it is important to understand the greenhouse effect. The greenhouse effect is the rise in the temperatures caused by absorption of the Sun’s heat and light by the Earth’s surface (forest, deserts, glaciers etc.), which then is reflected back and trapped within the Earth’s atmosphere.
The greenhouse gases help to keep the earth’s surface warm and this is the reason why life on Earth has existed and still thrives. Earth has gotten nearly 14% hotter than what it used to be 50 years ago, with 2005 being recorded as the hottest year ever. Besides humans and plants, a global warming effect on animals is a cause of concern.
As global warming causes climate change, many great deserts like the Sahara are no longer able to sustain their animal population. Loss of habitat is most vividly seen in the Arctic, where global warming is melting the glaciers, pushing the polar bears into extinction.
The melting glaciers have caused water levels to rise in May oceans, threatening to drown many tropical islands and forests that have animal life. The Gulf war oil spills, along with oil tanker spills, have devastated a large number of aquatic lives. Changes in weather patterns and coastlines affect the food patterns of most aquatic creatures.
Hibernation, breeding and migration:
Studies now indicate a change in the hibernation, breeding, and migration patterns of animals. It is believed that hibernation and egg lying or animal birth, which is important aspects of animal life, is now happening on an average of 5.1 days earlier per decade. This unhealthy pattern affects the newborn, and quite a few are now born with defects or are stillborn.
Early egg lying is one of the reasons why insects like butterflies and small birds are disappearing fast in North America, where higher temperatures lead to earlier spring seasons. Many animals and birds, including penguins or flamingos, travel long distances to warmer climates, for breeding purposes.
Devastation of the migratory routes and their habitat, has forced many of them to alter or not migrate at all. This forces them to seek alternative migration habitats, where they have to compete for food and shelter with other migratory or resident animals and birds.
The same is also happening in case of aquatic mammals, which prefer warmer waters for breeding and hibernation. Animals that migrate depending on seasonally-linked phenomena, such as the formation of ice, lakes and other water bodies and the availability of seasonal foods, also suffer, when the environmental conditions around their migratory destination changes.
xi. Other Effects of Global Warming:
(a) Himalaya Glaciers Are Shrinking:
The Himalayas is an enormous mountain range consisting of about 15,000 glaciers and some of the world’s highest peaks, including the 8,848 metre-high Mount Everest.
Three Himalaya glaciers have been shrinking over the last 40 years due to global warming and two of them, Yala in central and AX010 in eastern Nepal may disappear in coming time.
Using global positioning system and simulation models, they found that the shrinkage of two of the glaciers had accelerated in the past 10 years compared with the 1970s and 1980s.
Yala’s mass shrank by 0.8 metres (2.6 feet) and AX010 by 0.81 metres respectively per year in the 2000s, up from 0.68 and 0.72 metres per year between 1970 and 1990.
Apart from climate change and humidity, elevation of temperature also appears to play a critical role in the lifespan of glaciers, which are large persistent bodies of ice.
The Rikha Samba glacier in the drier region of west Nepal has also been getting smaller since the 1970s, but its rate of shrinking slowed to 0.48 metres per year in the past 10 years compared to 0.57 metres per year in the 1970s and 1980s.
This was because the 5,700 metre-high glacier was located on a higher altitude, which meant that losses in mass from melting could be compensated at least partly by collection of snowfall.
Yala and AX, are situated on lower elevation (altitudes), therefore shrinkage was accelerated. These glaciers have no chance to get snow mass and so will eventually disappear.
(b) Global Warming and Hurricanes:
Nature has its own ways of showing anger to the mankind. From times immemorial mankind has been the victim of earthquakes, floods, asteroids hitting the earth, volcanoes, hurricanes, droughts and so on. A hurricane is the phenomenon of formation of a cyclonic storm system over the oceans.
It is caused by evaporated water that comes off of the ocean and becomes a storm. The Coriolis Effect causes the storms to spin and a hurricane is declared when this spinning mass of storms attains a wind speed greater than 74 megha per hertz.
There has been a clear increase in the frequency of tropical storms and major hurricanes in the North Atlantic. From 1850-1990, the long-term average number of tropical storms was about 10, including about 5 hurricanes.
For the period of 1998-2007, the average is about 15 tropical storms per year, including about 8 hurricanes. This increase in frequency correlates strongly with the rise in North Atlantic sea surface temperature and according to recent studies the reason for this temperature increase is global warming.
Global Warming and Antarctica:
Global warming has increased rapidly during the past few decades and consequently warmer temperatures in the Antarctic summer are causing massive ice sheets to break up and float away. It is potentially an enormous problem and if this trend continues, the Antarctic ice caps may begin to melt and cause sea- level rises globally measured in meters.
There are many cities around the world that are on the coast and they would be flooded and probably have to be abandoned. In many countries, especially poorer countries a large part of the population living in coastal regions faces similar threat. In some cases entire island nations could simply disappear in the Pacific Ocean.
The 770 square mile (1,994 Km2) Larsen A ice shelf disintegrated suddenly in January 1995. Secondly, the break-up of the Larsen B ice shelf in early 2002 has been also attributed to the effects of global warming.
The Larsen B ice shelf was about 220 m thick and during a 35 day period in early 2002 lost about 3,250 Km2 of ice into the ocean. It is thought to have been in existence for at least 400 years. Overall in the Antarctic Peninsula, seven ice shelves have between them declined in area by about 13,500 Km since 1974.
Moreover, the permanent ice cover of nine lakes on Signy Island has decreased by about 45% since the 1950.
The latest victim of rising temperature, Wilkins Ice Shelf is the largest slab of ice so far to disintegrate in the Antarctic. Until recently, it was anchored to the Charcot and Latady islands by an ice bridge. On April 5, 2009, the ice bridge snapped leading to huge (41 by 2.5 km) berg being broken away.
The Antarctic Peninsula, particularly the west coast of the Peninsula is warming at a rate 2 or 3 times faster than the global average. The average annual temperature of this region has increased about 2.5°C in the last 50 years.
Rising temperature causes ice shelves to break up as they are floating already this will not affect sea levels; it may cause the glaciers behind them to speed up their flow-rate considerably. These glaciers will add to sea level rise if they melt.
The marine and terrestrial life in Antarctica is also getting drastically affected by global warming. Antarctica’s only two flowering plant species that grow only on the Peninsula have spread considerably in the last few decades.
In some areas they are becoming the dominant species. Penguins (Pygoscelis adeliae) have also been suffering a steady decline in parts of the Antarctic Peninsula region for the last 20 years.
Moreover, studies (November 2004) have shown that stocks of krill in Antarctica have declined dramatically in recent years. Krill numbers may have dropped by as much as 80% since the 1970’s.
The decline in Krill may in turn account for the decline in the numbers of some penguin species.
Global Warming and Polar Bears:
Polar bears are adapted to freezing environments and they can survive at temperatures as low as -46°C. This is why they thrive in Antarctica where snow, sea ice, and glacial ice cover most areas year round. At warmer climates, polar bears overheat and die.
This is why global warming poses a great threat to the world’s population of polar bears. Already, the increase in global temperature has caused a significant reduction in sea ice. Although Arctic temperatures are still well within the tolerable range for polar bears, the thinning and melting of ice due to global warming has already caused a significant number of polar bear drowning’s.
The change in Arctic climate has also caused polar bears to face starvation due to food shortages since they are losing about three weeks for hunting on solid ice and feeding on their prey. Polar bears now weigh at least 15% less than they did just 30 years ago.
For a typical adult male, which would amount to about 150 pounds less in weight, 60% of the 20,000-25,000 polar bears will die off within the next 50 years.
In May of 2008, polar bears became classified as an endangered species because of the significant number of deaths caused by global warming.
Project Report # 5. Control of Global Warming:
Global warming has become one of the most serious issues in current affairs, politicians and environmentalists due to the various risks and effects associated with it.
Despite the fact that global warming is increasing at an alarming rate and it might be too late to restore the damage it has caused, it is believed that developing an aggressive plan of action can help to reduce its negative impact.
Some suggestions to reduce global warming are:
i. Lighting:
Use Compact Fluorescent Light (CFL) bulbs. These use 60% less energy than incandescent bulbs. By using CFLs, we can save around 140 kg of CO2 each year.
ii. Proper Heating, Cooling and Ventilation:
Use programmable thermostats, lowering thermostat by 2°C during the winter. Proper thermostat setting will keep from emitting over 900 kg of CO2 each year. Up-to 160 kg of CO2 can be saved annually by cleaning air conditioning and furnace filters regularly.
Using double-glazed windows and insulating ceilings and walls properly will not only reduce energy bill by around 25% but also reduce annual CO2 emissions by over 900 kg. Weather-stripping and caulking will also reduce from emitting up to 800 kg. of CO2 a year.
iii. Appliances, Fixtures and Equipment:
Use energy efficient appliances. Keep refrigerator and freezer away from cooker and boilers. This can help in reducing yearly CO2 emissions by 160-320 kg. If you have a water heater, wrap it with an insulation blanket and set its thermostat to a maximum of 50°C. These can help us to reduce our yearly CO2 emissions by 700 kg.
iv. Bathroom, Kitchen and Laundry Practices:
Dry your laundry outdoors rather than using a dryer. Doing this can help you keep from emitting up to 635 kg of CO2 each year.
Use the least possible amount of hot water in bathroom, kitchen and laundry room. By using warm or cold water to wash clothes up to 230 kg of CO2 could be saved per year.
v. Waste Management:
Send all recyclables to recycling plants. Recycle at least half of household’s waste can save up to 1,100 kg of CO2 per year. Also, compost organic waste to reduce methane emissions.
vi. Transportation:
Transportation sector is second largest contributor of carbon dioxide emissions into the atmosphere. Drive less, take bikes, walk or carpool whenever possible.
vii. Maintenance:
If only 1% of all car owners maintained their cars properly, annual CO2 emissions can be reduced by up to 453, 592, 370 kg. Also properly inflated tires at all times as tire pressure greatly affects gas mileage 9 kg of CO2 can be saved from being emitted into the atmosphere by saving just 1 gallon of gasoline.
Some more suggestions to reduce global warming are:
1. Consider investing in a hybrid or electric vehicle to help prevent against further global warming.
2. Clean or replace your filters monthly.
3. Choose energy-efficient appliances when it’s time to buy new ones.
4. Decrease your air travel.
5. Wash clothes in cold water and line-dry whenever possible.
6. Cut down on your garbage-buy fewer packaged materials to prevent further global warming. Composting is another efficient option that an significantly reduce landfill spaces.
7. Unplug electronics when they are not in use, because they still take up energy. At the very least, turn items off when they’re not being used.
8. Run the dishwasher and clothes washer only when you have a full load, and if available, use the energy-saving setting.
9. Buy recycled paper products and recycle as much of your waste as possible.
10. Plant a tree. Trees can be an effective solution in countering this serious problem.
11. Use non-toxic cleaning products that are environment friendly.
12. Eat less meat and more organic foods in your diet to do your part in preventing global warming. This is one of the most effective ways to reduce our personal carbon footprint and to generally reduce our personal negative impact on the environment.
