Global warming happens when the temperature of the earth’s surface rises. The major contribution towards global warming is the emission of greenhouse gases like carbon dioxide, methane, nitrous oxide into the air. Global warming can cause serious climate change and can be a grave concern for the health of human beings and all other living beings on this earth. The “greenhouse effect” is considered as the principal cause of climate change. However, the contribution of greenhouse is a controversial issue. Without the effect of the greenhouse, the surface of the earth would have been much colder than the current temperature. This is one reason why greenhouse effect cannot always be considered as a problem. “The real problem is the enhanced, human-induced, greenhouse effect” (Gardiner, 2004, p.558).
The effects of climate change can have vast impact on the biological life on this earth. Some of the impacts that have been observed so far are “melting of glaciers, changes in Arctic ecosystems, warming of lakes and rivers, effects on agriculture and forestry, sea-level rise and coastal flooding in some areas”. Although reports say the impact of climate change will vary in different regions, the poor communities will be more likely to be affected. The reason behind this is that the poor people have “limited adaptive capacities” and depend mostly on “climate sensitive resources like local water and food supplies” (Winston & Edelbach, 2011, p.362).
It is necessary to reduce the emissions of greenhouse gases. This can be done by the use of “fuel-efficient vehicles” and by constructing “energy-efficient buildings”. The most important thing is to learn to become adaptive to climate change and also it is necessary to guide the developing countries towards economic development (Winston & Edelbach, 2011, p.363).
According to Gardiner the industrial nations are more responsible for the current grave condition
