- 2. WHAT IS GLOBAL WARMING? Global warming means the rise in the Global temperature. The primary cause for Global Warming are human activities such as burning fossil fuels to release poisonous gases to our environment and destroying forests from which we cannot get enough oxygen so that is why carbon-dioxide is increasing in the environment which traps more sunlight and drives up the planet’s temperature causing the glaciers to melt, rise in the sea level and forests to dry etc. These are the reasons why we say the humans are major cause for the Global Warming.
- 3. CAUSES OF THE GLOBAL WARMING One of the biggest issues facing us right now is global warming. Its effects on animals and on agriculture are indeed frightening, and the effects on the human population are even scarier. The facts about global warming are often debated in politics and the media, but, unfortunately, even if we disagree about the causes, global warming effects are real, global, and measurable. The causes are mainly from us, the human race, and the effects on us will be severe.
- 4. 1. Global Warming Cause: Carbon dioxide emissions from fossil fuel burning power plants. 2.Global Warming Cause: Carbon dioxide emissions from burning gasoline for transportation.
- 5. 3. Global Warming Cause: Methane emissions from animals, agriculture such as rice paddies and from Arctic sea beds. 4. Global Warming Cause: Deforestation, especially tropical forests for wood, pulp, and farm land.
- 6. 5.Global Warming Cause: Increase in usage of chemical fertilizers on croplands.
- 7. IMPACT OF GLOBAL WARMING ON THE ENVIRONMENT 1.Accelerating sea level rise and increased coastal flooding: Global Warming is now accelerating the rate of sea level rise , increasing flooding risks and high risk at coastal areas. 2. Longer and more damaging wildfire seasons: Wildfires are increasing and wildfire season is getting longer as temperatures rise. Higher spring and summer temperatures as ice melts earlier.
- 8. 3.More frequent and intense heat waves: Dangerously hot weather is already occurring more frequently than it did 60 years ago. This increase in heat waves creates serious health risks, and can lead to heat exhaustion, heat stroke, and aggravate existing medical conditions. 4.National Landmarks at Risk: The growing consequences of climate change are putting many of the country's most iconic and historic sites at risk.
- 9. 5.Widespread forest death in the Rocky Mountains: Tens of millions of trees have died in the Rocky Mountains over the past 15 years because of tree-killing insects, wildfires and stress from heat and drought. 6.Costly and growing health impacts: Rising temperatures will likely lead to increased air pollution, a longer and more intense allergy season, the spread of insect-borne diseases, more frequent and dangerous heat waves, and heavier rainstorms and flooding
- 10. 7.An increase in extreme weather events: Strong scientific evidence shows that global warming is increasing certain types of extreme weather events, including heat waves, coastal flooding, extreme precipitation events, and more severe droughts. Global warming also creates conditions that can lead to more powerful hurricanes. 8. Heavier precipitation and flooding: As temperatures increase, more rain falls increasing the risk of flooding events which can cause severe damage to our Environment and habitats of many living things including humans and animals.
- 11. 9. Lack of Food: This is because when there would be more carbon-dioxide in Earth rather than oxygen, the farms and fields would start to dry out instead of growing and even because of floods which occur due to the rise in sea level which will destroy the pastures and fields.
- 12. SOLUTIONS OF GLOBAL WARMING There is no single solution to global warming, which is primarily a problem of too much heat-trapping carbon dioxide (CO2), methane and nitrous oxide in the atmosphere .The technologies and approaches outlined below are all needed to bring down the emissions of these gases by at least 80 percent by mid-century. Achieving goal is possible because nothing is impossible.
- 13. Greening transportation: A variety of solutions are at hand, including improving efficiency (miles per gallon) in all modes of transport, switching to low-carbon fuels, and reducing vehicle miles traveled through smart growth and more efficient mass transportation systems. Revving up renewables : Renewable energy sources such as solar, wind, geothermal and bio energy are available around the world. Multiple studies have shown that renewable energy has the technical potential to meet the vast majority of our energy needs. Renewable technologies can be deployed quickly, are increasingly cost-effective, and create jobs while reducing pollution.
- 14. Phasing out fossil fuel electricity: Dramatically reducing our use of fossil fuels, especially carbon-intensive coal is essential to tackle climate change. There are many ways to begin this process. Key action steps include: not building any new coal-burning power plants, initiating a phased shutdown of coal plants starting with the oldest and dirtiest, and capturing and storing carbon emissions from power plants. Demonstration projects to test the viability and costs of this technology for power plant emissions are worth pursuing.
- 15. Managing forests and agriculture: Taken together, tropical deforestation and emissions from agriculture represent nearly 30 percent of the world's heat-trapping emissions. We can fight global warming by reducing emissions from deforestation and forest degradation and by making our food production practices more sustainable. Exploring nuclear: Because nuclear power results in few global warming emissions, an increased share of nuclear power in the energy mix could help reduce global warming—but nuclear technology poses serious threats to our security and, as the accident at the Fukushima Diarchy plant in Japan illustrates to our health and the environment as well.
- 16. Developing and deploying new low-carbon and zero-carbon technologies: Research into and development of the next generation of low-carbon technologies will be critical to deep mid-century reductions in global emissions. Current research on battery technology, new materials for solar cells, harnessing energy from novel sources like bacteria and algae, and other innovative areas could provide important breakthroughs. Ensuring sustainable development: A successful global compact on climate change must include financial assistance from richer countries to poorer countries to help make the transition to low-carbon development pathways and to help adapt to the impacts of climate change.
- 17. Energy Efficiency: May well be the most rapid and cost-effective tool to reducing carbon dioxide (CO2) emissions, yet it is still overlooked by many businesses and governments. Increases in energy efficiency must be seen as a crucial part of reducing CO2 emissions and minimizing our dependence on fossil fuels. Renewable Energy : Generated from natural sources – water, wind, solar, biomass or geothermal – will play a key role in replacing the world's dependence on fossil fuel based energy sources, such as coal, oil and natural gas which are not renewable. This means once that source of energy has been used, it is gone!
- 18. Carbon-capture and storage (CCS) : It is technology that removes and stores the CO2 during the production of energy from fossil fuels. With further research and investment, CSS technology may prove to be the bridging technology needed to 'get us over the line. Preventing forest loss: It will go a long way to reducing the threat of climate change. Forests are the largest storehouse of carbon, after coal and oil. When they are destroyed by logging and clearing for developing , massive quantities of CO2 is released into the atmosphere.
