Climate change refers to the changes that occur in the worlds climatic systems caused by anthropogenic emissions of green house gases. As stated by the Paris accord, the world’s countries have agreed to limit the global temperature increase to no more than 2°C above the pre-industrial levels. At the same time, the countries have also pledged to aim for a global average increase of 1.5°C. Science is already and will continually play a crucial role in the mitigation and adaptation to climate change.
