There is no debate more controversial in current science than the issue of global warming and climate change. Ever since the creatin of the Intergovernmental Panel on Climate Change (IPCC) in1988, scientists, politicians, and the news media have been discussing and debating the greenhouse effect, global warming and climate change all over the world. This paper/poster presents the summary of the 2007 IPCC Report (AR4) on climate change, and discusses various issues on both sides of the debate. The poster investigates the complexity of the climate system, greenhouse gases, carbon cycle and sources/sinks of CO2, climatic processes involved in the greenhouse effect, partial contribution of various greenhouse gases to the greenhouse effect, and our level of understanding of the greenhouse effect. It also presents the opposing views on global warming and climate change, trends in global temperature, hurricane frequency and intensity, snow and ice cover in Antarctica, tornado occurrences, model predictions, and projection of future climate and its verification. It also discusses the developments that took place since the UN Climate Change Conferences held in Copenhagen, Denmark, December, 2009, and in Durban, South Africa in December 2011. It also looks at whether the IPCC works with scientific objectivity and transparency in dealing with the aspects of climate science.
