GLOBAL WARMING
MEANING
Global warming is the rise in average global temperature due to human activities, such as, the emissions of greenhouse gas pollution produced by the burning of fossil fuels and land-use changes like deforestation.
Greenhouse Gases (GHGs)
• GHGs are atmospheric gases.
• Water Vapor, Carbon dioxide, Methane, Nitrous Oxide & Ozone are naturally occurring GHGs
• GHGs that are only caused by humans are Clorofluorocarbons (CFCs), Hydrofluorocarbons (HFCs), Perfluorocarbons (PFCs) & Sulphur hexafluoride.
Greenhouse Gases (contd…)
?CO2
• Principle GHG • Emission caused by energy & power plants that undergo the burning of fossil fuels, automobiles, airplanes, buildings, traffic jams emit CO2 • Some GHGs can trap more heat from CO2 (like water vapor) some by a thousand times greater :? But overall, they have much lower concentrations ? Thus, no gas add as much warmth to the atmosphere as CO2
? Humans
? Directly & indirectly caused global warming
? Industrialisation increased GHGs rapidly accelerating the Greenhouse Effect ? US largest source of global warming pollution :• Makes up 4 % of world population but produces 25 % of CO2 from fossil fuels burning • emits more than China, India & Japan ? Burning of fossil fuels & organic matter in power plants to generate electricity ? Fertilizers, presence of methane in agriculture
?Deforestation
? blamed for 25% of all CO2 release entering the atmosphere by the cutting & burning of about 34 million acres a year. ? Responsible for absorbing about 2 billion tons of CO2 so less trees causes a greater concentration of CO2 in the atmosphere
?Natural Causes
? Oceans, rainforests naturally release nitrous oxide as the Arctic Tundra & Wetlands naturally release methane gas
? Earth goes through the process of warming & cooling ? But…..humans speed up these processes & dramatize its effect to drastic levels for changes & improvements
Greenhouse Effect
• Warming happens when certain gases in earth's atmosphere trap heat.
• These gases let in light but keep heat from escaping like the glass walls of a greenhouse.
• First, sunlight shines onto the Earth's surface, where it is absorbed and then radiates back into the atmosphere as heat.
• In the atmosphere, ?greenhouse? gases trap some of this heat and the rest escapes into space. The more greenhouse gases are in the atmosphere, the more heat gets trapped.
Greenhouse Effect (contd….)
• Through the burning of fossil fuels and other GHG emissions, humans are enhancing the greenhouse effect and warming Earth.
• The rapid rise in greenhouse gases is a problem because it is changing the climate faster than some living things may be able to adapt. Also, a new and more unpredictable climate poses unique challenges to all life.
Effects Of Global Warming
? BIODIVERSITY LOSS
• Thousands of species risk extinction from disappearing habitat, changing ecosystems and acidifying oceans. • According to the IPCC, climate change will put some 20% to 30% of species globally at increasingly high risk of extinction, possibly by 2100.
? Acidifying oceans
• About one-third of the CO2 pollution from smokestacks and tailpipes is absorbed by the world's oceans, where it forms carbonic acid. • A 2010 study published in Nature Geoscience warns that unchecked greenhouse gas emissions could cause oceans to acidify at a rate unprecedented in at least the last 65 million years.
?Decline in polar bears
• Arctic sea ice is the polar bear's feeding habitat. As sea ice disappears, bear mortality rises.
• In 2008, the polar bear became the first animal to be added to the Endangered Species Act list of threatened species because of global warming.
? Coral bleaching
• Coral reefs are highly sensitive to small changes in water temperature. Heat triggers corals to shed the algae that nourish them—a bleaching event that leaves coral white. • In 1998, the world's coral suffered its worst year on record, which left 16% bleached or dead. • Continued warming could cause mass bleachings to become an annual event within the next few decades, wiping out many reef ecosystems.
?Shifting habitat
• As the mercury rises, plants & animals are shifting their ranges toward the poles and to higher altitudes & migration patterns for animals as diverse as whales and butterflies are being disrupted.
? Threats to Western forests
• The U.S. Geological Survey reports that slight changes in the climate may trigger abrupt ecosystem changes that may be irreversible. • The Rocky Mountains in Canada and the U.S. have seen nearly 70,000 sq miles of forest die – an area the size of Washington state – since 2000 due to outbreaks of tree-killing insects.
?Thinning ice, rising seas
• Rising seas are one of the most certain effects of global warming as warming ocean waters expand and melting glaciers, ice caps and ice sheets add more water to the oceans. • The IPCC estimates that melting ice caps and glaciers—which are some of our most visible indicators of climate change—accounted for about 25% of sea level rise from 1993 to 2003. • Larsen area of North Antarctic, South of Chili and Argentina have lost more than 5,200 sq miles of area.
? Arctic sea ice is shrinking
• The extent of Arctic summer sea ice has decreased by almost 9% per decade since 1979
• The Arctic summer could be ice-free by mid-century, according to a study by the National Oceanic and Atmospheric Administration.
? Sea level rise
• During the 20th century, sea level rose an average of 7 inches after 2,000 years of relatively little change.
• The IPCC Report 2007 conservatively predicts that sea levels could rise 10 to 23 inches by 2100 if current warming patterns continue. • The U.S. Geological Survey said in a report in 2009 warning that most mid-Atlantic coastal wetlands from New York to North Carolina will be lost with a sea level rise of 3 feet or more. North Carolina's barrier islands would be significantly breached and flooding would destroy the Florida Everglades.
?Melting glaciers
• A 2005 survey of 442 glaciers from the World Glacier Monitoring Service found that 90% of the world's glaciers are shrinking as the planet warms.
• Glacier National Park now has only 25 glaciers, versus 150 in 1910. • At the current rate of retreat, The glaciers in Glaciers National Park could be gone in a matter of decades, according to some scientists.
? Threats
to people around the globe
• Extreme weather will become more frequent and more dangerous. • The World Meteorological Organization reported that 2000-2009 was the hottest decade on record, with eight of the hottest 10 years having occurred since 2000. • Scientists say global warming is speeding up the cycling of water between the ocean, atmosphere and land, resulting in more intense rainfall and droughts at the same time across the globe.
?A surge in wildfires
• Hot & dry conditions create a tinderbox ideal for wildfires. • This could have a devastating impact on America’s Southwest.
? Increased flooding
• The IPCC Report 2007 concludes that intense rain events have increased in frequency during the last 50 years and that humaninduced global warming has been a factor.
?Increased drought
• There have also been increased periods of drought, particularly in famine-stricken areas of Africa and Asia. According to the National Center for Atmospheric Research, the percentage of Earth's surface suffering drought has more than doubled since the 1970s. In Africa alone, the IPCC projects that between 75 and 250 million people will be exposed to increased water stress due to climate change.
? More intense hurricanes
• As the oceans warm, scientists predict that hurricane intensity could increase.
?Threats to human health
• A warming planet threatens people worldwide, causing deaths, spreading insect-borne diseases and exacerbating respiratory illnesses. Extreme weather will also put more people in harm's way.
• The World Health Organization believes that even the modest increases in average temperature that have occurred since the 1970s are responsible for at least 150,000 extra deaths a year—a figure that will double by 2030, according to WHO's conservative estimate.
? Devastating heat waves
• Recent studies show that extreme heat events that now occur once every 20 years will occur about every other year in much of the country, if current trends continue. • In 1995, Chicago suffered a heat wave that killed more than 700 people. Chicagoans could experience that kind of relentless heat up to 3 times a year by 2100.
? Spread of disease
• Diseases such as malaria and dengue fever could become more difficult to control in areas where it's currently too cold for them to spread year-round • The malaria parasite itself is generally limited to certain areas by cooler winter temperatures since it is not able to grow below 16°C. As temperatures rise, diseases can grow and disease vectors (the carriers that transmit disease such as mosquitoes) will mature more rapidly and have longer active seasons.
? Worsening air quality
• Higher temperatures cause higher emissions of one type of pollutant, namely hydrocarbons and other volatile organic compounds, as well as speeding up the chemical reactions that form ozone smog.
• Smog triggers asthma attacks and worsens other breathing problems. The number of Americans with asthma has more than doubled over the past two decades to 20 million. • Continued warming will only worsen the problem.
FACTS ABOUT GLOBAL WARMING
• The Kyoto Protocol is an amendment to the United Nations Framework Convention on Climate Change (UNFCCC), an international treaty on global warming. It also reaffirms sections of the UNFCCC. Countries which ratify this protocol commit to reduce their emissions of carbon dioxide and five other greenhouse gases, or engage in emissions trading if they maintain or increase emissions of these gases. A total of 141 countries have ratified the agreement. • We can curb global warming pollution, save consumers money and curtail our reliance on oil.
• Current estimates are that even if successfully and completely implemented, the Kyoto Protocol is predicted to reduce the average global temperature by somewhere between 0.02°C and 0.28°C by the year 2050
• Using current and cutting-edge technology that will reduce our use of fossil fuels. By switching to energy efficient cars and trucks and clean & renewable energy.
OZONE DEPLETION
OZONE LAYER
• Ozone is a highly reactive form of oxygen.
• The ozone layer is a belt of naturally occurring ozone gas that sits 9.3 to 18.6 miles (15 to 30 kilometers) above Earth and serves as a shield from the harmful ultraviolet B radiation emitted by the sun. • Ozone exists within the troposphere & stratosphere zones of the earth’s atmosphere. • In the troposphere, ground level ozone is a major air pollutant & primary constituent of photochemical smog.
• In the stratosphere, the ozone layer is an essential protector of life on earth as it absorbs harmful UV radiation before it reaches the earth’s surface. • Ozone depletion damage gets much worse when the stratosphere is very cold. This has been the case the past two years, causing extensive ozone depletion. Ozone depletion reached the most severe levels ever recorded over the Northern Hemisphere. Western United States ozone levels also continue to drop 3-4 percent per decade. • Even if all of our efforts to stop harmful emissions are successful, the ozone layer is not expected to begin recovery until around 2020 at the earliest.
CFC’s and Ozone Depletion
• Chlorofluorocarbons are created and used in refrigerators and air conditioners. • These chlorofluorocarbons are not harmful to humans and have been a benefit to us. • Once released into the atmosphere, chlorofluoro carbons are bombarded and destroyed by ultraviolet rays. • In the process chlorine is released to destroy the ozone molecules
Ozone destruction by UV rays
• UV radiation from the sun releases the radicals Chlorine Chlorine monoxide . and
• Ozone is a highly unstable molecule so it readily donates its extra oxygen molecule to free radical species such as hydrogen, bromine and chlorine. • These compound species act as catalysts in the breakdown of ozone molecules.
Responsible for ozone damage each year
Effects of UV rays
• decreasing the diversity of aquatic organisms – reduces food stock and also destroys several fish and amphibians. • Damage to plant cell DNA molecules - makes plants more susceptible to pathogens and pests • Reductions in photosynthetic capacity in the plant - results in slower growth and smaller leaves
• Skin cancer
• Premature aging (photoaging) of the skin (different from normal chronological aging) • Cataracts and eye disorders (corneal sunburn and blindness) • Immune system damage
SOLUTIONS TO GLOBAL WARMING
• Use energy efficient products • Switch off gadgets when not in use • Stop deforestation • Use public transport • Explore renewable sources • Carbon credits

Sony formulates the following goals in four key environmental aspects and takes proactive actions to achieve those goals.
?Climate Change
• Sony reduces energy consumption and strives to achieve zero emissions of greenhouse gases* generated throughout the lifecycle of our products, service and business activities.
?Resources Conservation
• In order to minimize resource inputs for our business activities, Sony identifies "Key Resources" and strives to achieve zero usage of those virgin materials. Sony also uses water efficiently, minimizes wastes from sites and maximizes our effort for take back and recycling products from markets.
? Management of Chemical Substances
• Sony minimizes the risk of chemical substances that we use causing serious harm to human health and the environment. Sony maintains strict control over the chemical substances we use, while, in line with the precautionary approach, taking steps whenever possible to reduce, substitute and eliminate the use of substances that have potentially significant impacts on the environment even in the cases where scientific evidence is not fully proven.
? Biodiversity Conservation
• Sony protects and utilizes ecosystem services in a sustainable manner, while actively promoting maintenance and recovery of biodiversity through our business and local contribution activities.
?Green Management 2010
• Green Management 2010 encompasses individual targets for the entire business cycle, from the procurement of parts, production and product use through to product disposal and recycling • Under Green Management 2010, Sony achieved an absolute reduction in greenhouse gas emissions from sites (calculated in terms of CO2) of more than 30% from the fiscal year 2000 level, well above of its target of a 7% reduction under Green Management 2010.
• Sony succeeded in reducing total waste from sites by more than 50% from the fiscal year 2000 level, exceeding its Green Management 2010 target of 40%. Additionally, Sony achieved an absolute reduction in volume of water purchased or drawn from groundwater of approximately 41%, surpassing its target of 20%. In contrast, Sony’s waste reuse/recycle ratio at manufacturing sites outside Japan, at 87%, fell short of its Green Management 2010 target of 95%, despite the fact that the waste reuse/recycle ratio at manufacturing sites in Japan reached 99.6%.
TATA Group
? Going green
? Tata Power has begun moving away from the business-as-usual scenario of coal-heavy plants to an ?aggressively renewable? portfolio and it has an ambitious plan mapped out till 2030. ? About 20 per cent of their installed capacity comes, as of now, from non-carbon sources. They expect this to rise to 24 per cent by 2017, 40 per cent by 2025 and 50 per cent by 2030. ? Diesel is the fuel that the majority of Tata Motors vehicles run on, and the company has consciously tried to make its vehicles less polluting and more fuel efficient. ?India meets almost 70 per cent of its fossil fuel requirements through imports, so the issue here is not just emissions but also energy usage.
• Apart from the diesel and other conventional-fuel vehicles it produces, Tata Motors is experimenting with alternative technologies that use biodiesel, combination fuels, etc. Also, it is developing CNG- hybrid buses. • Since 2 per cent of greenhouse gas emissions are attributed to the information technology industry, TCS is now in the business of crafting and delivering green offerings for its clients on the outside. It has a business unit that advises customers on setting up green infrastructure and operations. • Tata Chemicals approach on climate change focuses on energy reduction. the company is concentrating attention on achieving a 20 per cent reduction in the carbon intensity of its products by 2020.
