Climate change continues to be a global issue. In 2016, there is a sense of optimism after the success of COP21 last December. Climate change is defined as a change in global or regional climate patterns; in particular, a change apparent from the mid- to late 20th century onwards, and attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels. Climate change poses the biggest potential threat to the global economy in 2016.
Climate change will have a significant effect on food security worldwide, specifically for the poor and for people living in tropical regions, according to a new international report from the National Center for Atmospheric Research (NCAR).
