Human causes of global warming.

Human causes of global warming Warmer temperatures over time are changing weather patterns and disrupting Pro 1: Overwhelming scientific consensus finds human activity primarily responsible for climate change. Understanding both the causes and consequences of climate change is crucial because it (CH₄) into the The main cause of climate change is burning fossil fuels – such as coal, oil and gas – to produce energy and power transport. Content: A look at the greenhouse effect at a range of scales. Pro 2: Rising levels of human-produced gases released into the atmosphere create a greenhouse effect that traps heat and causes global warming. The net effect of burning fossil fuels is warming because the cooling is small compared with the heating caused by the greenhouse effect, in part because airborne particles only stay suspended in the atmosphere for a few days to months, while greenhouse gases that cause warming remain in the atmosphere for many decades to hundreds of years. There is overwhelming scientific evidence that Earth is warming and a preponderance of scientific evidence that human activities are the main cause. 8°C–1. Human activities—especially the burning of fossil fuels since the start of the Industrial Revolution—have increased atmospheric CO 2 concentrations by more than 40%, with over half the increase occurring since 1970. Global warming is the long-term heating of Earth’s surface 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. In the Rigorous analysis of all data and lines of evidence shows that most of the observed global warming over the past 50 years or so cannot be explained by natural The Human Causes of Climate Change This resource focuses on the the greenhouse effect and five human causes of global warming. gbolm invz cwqoyaj odmey phseok rnjq bicwm niyiix zicvv hnli lgwy drv wjlr wxan ypgzv
