What needs to be done to achieve greenhouse gas reduction targets by 2020? Since the beginning of Industrial Revolution‚ concentrations of carbon dioxide‚ methane‚ and nitrous oxide have all risen dramatically because of human activities. Fossil fuel combustion‚ land-use change‚ increasingly intensive agriculture‚ and an expanding global human population are the primary causes for these increases. Other greenhouse gases found in our planet’s atmosphere include water vapor and ozone. Carbon

increasing levels of greenhouse gases and/or other factors. This distinguishes it from the natural warming effect of greenhouse gases at their long-term normal level. The cause of Global Warmig is believed to be caused by a natural fact. An example of natural factors can be solar activity‚ greenhouse effect and a host of other things. To really understand Global Warming one has to know exactly what the greenhouse effect is and how it contributes to Global Warming. The Greenhouse Effect is the process

the average temperature across the world to rise substantially. In addition‚ the rise of use in gases like Carbon Dioxide that are referred to as “greenhouse” gases‚ may be a primary cause. Global Warming refers to a raise in atmospheric temperatures and oceanic temperatures that are generally assumed to happen due to an increase in the greenhouse effect resulting especially from pollution (“What Is Global Warming?”). This endangers the life of our earth and the people‚ plants‚ and animals that

as an increase in the Earth ’s atmospheric and oceanic temperatures widely predicted to occur due to an increase in the greenhouse effect resulting especially from pollution (“Global warming”). The buildup of these greenhouse gases can cause harsh changes to the Earth’s climate resulting in dangerous effects to human health ("Climate change basics"). The majority of greenhouse gases come from the burning of fossil fuels used to produce energy; although deforestation‚ industrial processes‚ and some

warming means a gradual increase in the Earth’s average lower atmosphere due to emissions and build up of greenhouse gases . Global warming is when the earth heats up and the temperature rises. It happens when greenhouse gases such as carbon dioxide‚ water vapor‚ nitrous oxide‚ and methane trap heat and light from the sun in the earth’s atmosphere‚ which increases the temperature. Most greenhouse gases are released by the burning of fossil fuels for heating‚ cooking‚ electrical appliances‚ transportation

attributing the recent global warming to human activities rests on the following undisputed scientific facts: • Carbon dioxide (CO2) is a greenhouse gas that warms the atmosphere. • Since pre-industrial times‚ atmospheric CO2 concentrations have increased from about 280 parts per million (ppm) to over 380 ppm. Current concentrations of CO2 and other greenhouse gases are unprecedented in at least the last 650‚000 years‚ based on records from gas bubbles trapped in polar ice. • Independent measurements

actions of humans. But this is not just a belief‚ this is a fact. Global warming‚ by definition‚ is a gradual increase in the overall temperature of the earth ’s atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide‚ CFCs‚ and other pollutants. The greenhouse effect is the trapping of the sun ’s warmth in a planet ’s lower atmosphere due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from

Global Warming and its Effects What is global warming? Global warming is when the earth heats up (the temperature rises). It happens when greenhouse gases (carbon dioxide‚ water vapor‚ nitrous oxide‚ and methane) trap heat and light from the sun in the earth’s atmosphere‚ which increases the temperature. This hurts many people‚ animals‚ and plants. Many cannot take the change‚ so they die. However‚ global warming has its causes and it also has its effects on humans‚ and animals.

An increase in the earth’s atmospheric and oceanic temperatures is widely predicted to occur due to an increase in the greenhouse effect resulting from pollution. Atmosphere carbon dioxide (CO2) is known as a Greenhouse gases‚ which means the increased levels of carbon dioxide in the atmosphere can lead to global warming which
