4th Assessment Report

The Fourth Assessment Report (AR4) by the Intergovernmental Panel on Climate Change (IPCC), released in 2007, synthesizes extensive scientific research on climate change. It confirms that global temperatures are rising mainly due to increased greenhouse gases from human activities like burning fossil fuels. The report highlights observed climate impacts, such as melting glaciers, more frequent extreme weather events, and rising sea levels. It emphasizes that these changes pose risks to ecosystems, economies, and societies. The report underscores the urgent need for action to reduce emissions and adapt to ongoing climate impacts, serving as a comprehensive scientific basis for international climate policy discussions.
