energy that‚ in turn‚ emits about 160 pounds of the greenhouse gas carbon dioxide (CO₂) per year per machine. Just supplying the water for washing machines consumes a considerable amount of energy. In total‚ water supply and treatment facilities use about 50 billion kilowatt-hours per year. If 1 out of every 100 U.S. homes switched to water-efficient appliances‚ the energy savings could reach 100 million kWh per year and reduce greenhouse gas emissions by 75‚000 tons. According to recent U.S

on Climate Change (IPCC) concludes‚ "most of the observed increase in globally averaged temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations‚"[1] which leads to warming of the surface and lower atmosphere by increasing the greenhouse effect. Natural phenomena such as solar variation combined with volcanoes have probably had a small warming effect from pre-industrial times to 1950‚ but a cooling effect since 1950. The basic

from global warming. Rich industrialised countries in the West have been burning fossil fuel such as coal‚ oil and gas for about 150 years‚ pumping out vast quantities of carbon dioxide. This gas traps the heat from the sun and causes the Earth and the atmosphere to get warmer. This is called the greenhouse effect. So why global warming is a problem? Well‚ high level of these greenhouse gases in the atmophere causes climate changes‚ which also lead to ocean and sea levels to go up‚ because of melting

put in place to reduce the impact of these pollutants. CO2 is a greenhouse gas‚ a greenhouse gas is characterised as being a gas that absorbs infrared radiation and contributes to the greenhouse effect. We need the greenhouse effect in moderation as otherwise the Earth would be cooler and would not be able to support life as we know it‚ our two closest planets are examples of how temperatures can differ due to the greenhouse effect. Venus has an extremely dense atmosphere containing 96% CO2

Humans Are To Blame For Global Warming Kevin Odhiambo Ogwa Lake Michigan College Abstract Every human activity has a particular effect on objects surrounding his or her environment‚ be it physical‚ mental‚ or social. But notably‚ the most evident might be the effect of human activity on global warming. Global warming is quickly becoming a major topic of concern worldwide‚ and has been stirring up controversy everywhere with its adverse effects seen all over the world. It causes rise of the

United Nations Framework Convention on Climate Change (UNFCCC). It was raised the 11th of December of 1997 in the city of Kyoto to develop a package of measures to reduce anthropogenic greenhouse gases. The main objective of this treaty is to protect the planet from the effects of climate change and reduce the gas emissions which provoke the phenomenon known as global warming. Thus‚ taking into account the direct human responsibility in this environmental problem‚ this treaty tries to engage developed

And we are very keen to find some renewable method to produce energy which would be cheapest‚ durable and ecological. One of such method is “Bio-Gas’’ power plants. Energy is one of the major inputs for the economic development of any country. In the case of the developing countries‚ the energy sector assumes a critical importance in view of the ever-increasing energy needs requiring huge investments

And these severe weather events are exactly the kind of thing we’d expect to see as rising concentrations of greenhouse gases change our climate — which means that the current food price surge may be just the beginning. 2.
