Climate Change is a major environmental problem facing the globe today. It is decribed as a significant and lasting change in the statistical distribution of weather patterns over periods ranging from decades to millions of years. a change in global climate patterns apparent from the mid to late 20th century onwards, attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels.
It may be a change in the average weather conditions or a change in the distribution of weather events with respect to an average, for example, greater or fewer extreme weather events. Climate change may be limited to a specific region, or may occur across the whole Earth.
According to the National Oceanic and Atmospheric Administration (NOAA), there are seven indicators that are increasing and would be expected to increase in a warming world, they are: Humidity; Atmospheric Temperature; Sea surface temeperature; Sea level; Ocean Heat Content; Temperature over oceans, and; Temperature over land.
Three indicators are decreasing and would be expected to decrease even more, they are: Sea ice; Glaciers, and; Snow cover.
What is Sustainable Development (SD)?
The most frequently quoted definition of Sustainable Development is from Our Common Future, also known as the Brundtland Report: Sustainable development is "development that meets the needs of the present without compromising the ability of future generations to meet their own needs."
It contains within it two key concepts:
Thus the goals of economic and social development must be defined in terms of sustainability in all countries - developed or developing, market-oriented or centrally planned. Interpretations will vary, but must share certain general features and must flow from a consensus on the basic concept of sustainable development and on a broad strategic framework for achieving it.
Development involves a progressive transformation of economy and society. A development path that is sustainable in a physical sense could theoretically be pursued even in a rigid social and political setting. But physical sustainability cannot be secured unless development policies pay attention to such considerations as changes in access to resources and in the distribution of costs and benefits. Even the narrow notion of physical sustainability implies a concern for social equity between generations, a concern that must logically be extended to equity within each generation.
The Concept Sustainable Development focuses on the following:
