Through this initiative‚ the company invested liberally in renewable energy and cleaner technologies. It also promoted energy-efficient Ecomagination products through its marketing campaigns. Besides‚ the company set targets for reducing its greenhouse gas emissions and for increasing the energy efficiency of its operations. Industry observers noted that the strategy had been successful for GE as it was able to make good money. GE‚ which had set a target of investing US$ 5 billion in Ecomagination

to the greenhouse effect. I also have realized the impact that global warming can have on the earth. We as human’s need to do what we can to lower our contributions to the global warming before it is too late. Global warming is the increase of earth’s average surface temperature due to the effect of greenhouse gases‚ such as carbon dioxide emissions from burning fossil fuels or from deforestation‚ which traps heat that would otherwise escape from earth. This is a type of greenhouse effect

rapid global warming‚ scientists have examined all the factors that can affect the Earth’s temperature. There are essentially three factors that could be responsible for recent rapid global warming: 1. The sun 2. Earth’s reflectivity 3. Greenhouse gases Which of these is causing our current global warming? It’s not the sun: cause of little warming since 1750‚ none since 1980s Ultimately‚ the climate system is powered by the sun: all else being equal‚ if you turn up the sun‚ you’ll warm

If you don’t know what Global warming is it is the increase in the earth’s average temperature due to the release of several greenhouse gases into the atmosphere by humans. Global warming is affecting many different parts of the world and in turn causes a cause and effect. Glaciers are melting which is causing the sea level to rise. When the sea level rises it causes damage to people living in low lying areas‚ and damages to plants by covering them which causes them to die. Which in turn causes animals

temperature of Earth’s atmosphere and oceans since the late 19th century and its projected continuation. Since the early 20th century‚ Earth’s mean surface temperature has increased by about 0.8 °C. It is primarily caused by increasing concentrations of greenhouse gases like carbon dioxide and methane produced by human activities such as the burning of fossil fuels and deforestation. Human-induced warming of the climate is expected to continue throughout the 21st century and beyond. Global warming can cause

Defining climate change For most people‚ the expression “climate change” means the alteration of the world’s climate that we humans are causing‚ through fossil fuel burning‚ clearing forests and other practices that increase the concentration of greenhouse gases (GHG)1 in the atmosphere. This is in line with the official definition by the United Nations Framework Convention on Climate Change (UNFCCC) that climate change is the change that can be attributed “directly or indirectly to human activity

The Kyoto Protocol‚ which took effect on February 16‚ 2005‚ aims to reduce the amount of greenhouse gas emissions around the world. The debate whether the issue of climate change is valid or whether it is an exaggerated theory is still ongoing. Given that the Kyoto Protocol raises economic concerns and that it lacks overall effectiveness‚ Canada and businesses in general should not be in favour of it. This is in part because of the treaty’s conditions and partially because of the actions of other
