QUESTIONS 1.Essensial Que: Why temperature of the earth increases day by day? 2.Unit Que: 1.In which way pollution affects on increasing heat? 2. What are reasons of deforestations? 3.Content Que: 1.What are the types of pollution? 2.How concentration of co 2 increases in atmosphere?
an increase in the average temperature of the earth's atmosphere (especially a sustained increase that causes climatic changes) an increase of the earth's temperature by a few degrees resulting in an increase in the volume of water which contributes to sea-level rise A process that raises the air temperature in the lower atmosphere due to heat trapped by greenhouse gases, such as carbon dioxide, methane, nitrous oxide, CFCs and ozone.... GLOBAL WARMING
Causes of global warming Acid Rain Carbon Dioxide and Temperature Carbon exchanged between the atmosphere and reservoirs on the earthCarbon exchanged between the atmosphere and reservoirs on the earth A comic about the greenhouse effect Cost of achieving sustainable development Fate of emissions World energy consumption Energy habits Planning for future energy needs Energy flow Gasoline prices Heat trapping Methane concentration Developed nations and industrial emissions Developed nations and consumption Age distribution Local food production
Heat waves and periods of unusually warm weather HARBINGERS: Events that foreshadow the types of impacts likely to become more frequent and widespread with continued warming.HARBINGERS Downpours, heavy snowfalls, and flooding Droughts and fires Coral reef bleaching Spreading disease Arctic and Antarctic warming Glaciers melting Earlier spring arrival Ocean warming, sea-level rise and coastal flooding
GREENHOUSE EFFECT What Is The Greenhouse Effect? Seen from space, our atmosphere is but a tiny layer of gas around a huge bulky planet. But it is this gaseous outer ring and its misleadingly called greenhouse effect that makes life on Earth possible – and that could destroy life as we know it.
