Climate change may be defined as the incessant day to day variation taking place in the weather system throughout the world. The main factor behind the climate change is human generated activities like increased consumption of fossil fuel which in turn emits large amount of greenhouse gases like carbon dioxide (CO2), methane (CH4), chlorofluorocarbons, and nitrous oxide thereby resulting in global warming. The most extensive use among these is the increased use of carbon dioxide which comes due to consumption of fossil fuels and deforestation. With course of time rate of CO2 consumption and emission is increasing at a much faster speed than expected. There are various other factors contributing to climate change which are plate tectonic movements, volcanic eruptions, orbital variations, ocean-atmosphere variability. Climate Change 2019 will be a great event to discuss about the causes, impacts and solutions to mitigate climate change.
