Document Summary
Global warming is the long-term heating of earth"s climate system observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in earth"s atmosphere. The term is frequently used interchangeably with the term climate change. Climate change refers to both human- and naturally produced global warming and the effects it has on our planet. It is commonly measured as the average increase in earth"s global surface temperature. Greenhouse gas emissions: water vapor, carbon dioxide (co2, methane (ch4, nitrous oxide (n2o, fluorinated gas. The vast majority of anthropogenic ghg emissions come from the combustion of fossil fuels, deforestation, changes in land use including urbanization-, soil erosion and agriculture. Carbon emissions: only co2, most emissions are co2, biggest sources are from electricity, then transport. Most emissions come from china, us, eu, india. We are way off track to meet 1. 5 degree target.
