According to the recent report by the United Nations Intergovernmental Panel on Climate Change (IPCC), the global average temperature increase over the period 1850–1900 was about 1.1°C by the 2010s. Several countries in the world have seen increases in average temperatures approaching 2°C. From 1820 to 2016, gross domestic product (GDP) per capita in most of the Western world grew by about 25 times, and in the non-Western world by 13.5 times. This economic growth has been associated with enormous improvements in different indicators of human well-being, such as higher life expectancy, lower child mortality, and lower malnutrition.
