AR4 (Fourth Assessment Report)

The Fourth Assessment Report (AR4) was published by the Intergovernmental Panel on Climate Change (IPCC) in 2007. It assessed the latest scientific understanding of climate change, its impacts, and options for adaptation and mitigation. The report confirmed that human activities, particularly the burning of fossil fuels, are driving global warming. It highlighted potential consequences such as rising sea levels, extreme weather, and threats to ecosystems. AR4 emphasized the urgent need for action to reduce greenhouse gas emissions and prepare for climate change effects, serving as a crucial resource for policymakers and the public in understanding climate challenges.
