Fourth Assessment Report

The Fourth Assessment Report, published in 2007 by the Intergovernmental Panel on Climate Change (IPCC), synthesizes scientific research on climate change. It explains that the Earth's climate is warming primarily due to human activities, such as burning fossil fuels, which release greenhouse gases. The report highlights the associated risks like more extreme weather, rising sea levels, and impacts on ecosystems and human societies. It emphasizes the need for global efforts to reduce emissions and adapt to changing conditions to minimize future risks. Overall, it provides a comprehensive, evidence-based understanding of climate change and its implications.
