Global warming refers explicitly to an increase in Earth's average surface temperatures caused by human activities, primarily the burning of fossil fuels. Anthropogenic climate change refers to changes in the climate caused by human activity, particularly industrialization and agricultural practices that release pollutants into the atmosphere.Overwhelming scientific evidence supports the existence of both global warming and climate change. Through the United Nations' (UN) Intergovernmental Panel on Climate Change (IPCC), thousands of scientists work together to collect and analyze the latest available research related to climate change, its effects, and potential responses.
