Based on scientific understanding it can be easily explained that human activities that lead to an increase in Greenhouse Gases (GHGs) in the atmosphere, deforestation, land degradation, etc can cause changes in the climate. However, this is a very broad statement with a number of unspecified facts. Which element of climate is being considered? Is it the temperature alone? If so, is it the mean temperature of the earth or the minimum/maximum temperature? Is there observed data, spanning sufficient number of years, all over the world, to identify the climatic elements showing changes? With the existing scientific understanding and forecasting tools, can the future climate be predicted reasonably well? How useful is this type of prediction? Are the people, whose combined efforts are absolutely necessary to combat global warming, in a position to interpret the future climate scenarios given by the scientists? Is there proper coherence between the scientists, media, and the common man for correct dissemination of knowledge and information without any misconceptions? How to keep a proper balance between developmental issues and environmental preservation? Is there enough information available to formulate policies for arresting climate change? How effective is the exchange of ideas and information between scientists, communities, and policy makers? Many such questions can be asked, for which there is no appropriate answer. However, scientists realise that their research is very relevant to the society. Therefore, they are obliged to assess, as best as they can, the current status of the knowledge.
