Climate change
The Earth's climate has been changing since its inception, but the pace and severity of climate change that we are currently experiencing are unprecedented. Human activities, such as burning fossil fuels, deforestation, and agriculture, have caused a significant increase in greenhouse gas emissions, which trap heat in the Earth's atmosphere and cause global warming. This has resulted in a range of earth-changing climate effects, including rising sea levels, more frequent and severe weather events, and the loss of biodiversity.
