Human created climate change is caused by what

is commonly referred to as greenhouse gas emissions. These emissions primarily come from burning fossil fuels, such as coal, oil, and natural gas, as well as deforestation and other land-use changes. Greenhouse gases, such as carbon dioxide, methane, and nitrous oxide, trap heat in the Earth's atmosphere, leading to a warming of the planet's air and oceans. This, in turn, causes disruptions to the natural environment and human systems, such as rising sea levels, more frequent and severe weather events, and changes to ecosystems and agricultural productivity.
