IPCC Fifth Assessment Report: Overview of Climate Change Science
The Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment Report (AR5) provides a comprehensive overview of the state of knowledge on climate change science. Published in 2014, the report assesses the physical science basis, impacts, adaptation, and mitigation of climate change.
Key Findings
The AR5 concludes that:
- It is extremely likely that human influence has been the dominant cause of observed warming since the mid-20th century.
- Global mean surface temperatures have increased by about 0.85°C (1.5°F) since the late 19th century.
- Climate change is already affecting many aspects of the Earth's system, including global sea levels, ice cover, and weather patterns.
- Climate change is expected to continue for decades or centuries, even if greenhouse gas emissions are reduced.
- There are many mitigation and adaptation options available to address the challenges of climate change.
The AR5 is a key resource for policymakers, scientists, and the general public who are interested in understanding the science of climate change.
