Kyoto Protocol and Canada-Effects, Consequences and Controve essays Climate change is one of the most important and probably most challenging of environmental issues facing the world this century. Except climate change is more than an environmental problem. It is also an important political, social and most importantly an economic challenge due to the fact that how human beings respond to the environmental concerns raised by climate change will have far-reaching consequences for economic conditions and living standards around the world. The question of climate change is about global warming (not about air quality or smog). There are growing concerns about how increases in atmospheric greenhouse gases (GHGs), caused by human activities, are contributing to the natural greenhouse effect and causing a raise to the planets average temperature. While man made emissions account for only two percent of all sources of greenhouse gases worldwide, they have increased sharply in the past century and have been linked to the rising concentration of greenhouse gases observed in the atmosphere. Also, human activities have a big effect on the number of greenhouse gases emitted into the atmosphere, notably CO2-carbon dioxide-that is the most widespread of GHGs, is due to the heavy combustion of fossil fuels for energy use. Other GHGs are emitted in the atmosphere as a result of industrial processes, such as chlorofluorocarbons, hydrofluorocarbons, and tetrofluromethane, have become more widespread as well, although their atmosphe ric concentration are considerably lower than those of fossil fuels. In addition to rising levels of greenhouse gases in the atmosphere, scientist have also observed increases in the average temperatures and more notably changing climatic conditions around the world. If one takes a moment to think clearly, these climatic changes are very dangerous and extremely harmful. The higher the concentration of green house gases, the more extreme and erratic climate changes well see-...
