To what extent the causes of global climate change natural? What is ‘global climate change’? Climate change is a long-term change in the statistical distribution of weather patterns over periods of time that range from decades to millions of years. 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. Discussion of the predicted levels/amount of global climate change. Many greenhouse gases stay in the atmosphere for long periods of time. As a result, even if emissions stopped increasing, atmospheric greenhouse gas concentrations would continue to increase and remain elevated for hundreds of years. Moreover, if we stabilized concentrations and the composition of today's atmosphere remained steady (which would require a dramatic reduction in current greenhouse gas emissions), surface air temperatures would continue to warm. This is because the oceans, which store heat, take many decades to fully respond to higher greenhouse gas concentrations. The rapid increase in carbon dioxide emissions observed during the last 250 years is expected to continue for several decades to come. Various scenarios have been examined, depending on factors like fuel use and efficiency. Even the best case scenario predicts further increases in carbon dioxide emissions until about 2040. Many of the scenarios indicate that by the middle of the 21st century emissions of carbon dioxide should at least start to level off, though some predict increase in emissions throughout this century. Though the different scenarios predict a wide range of trends in carbon dioxide emissions, the predicted net effect on atmospheric carbon dioxide concentrations in the future is fairly
