The Intergovernmental Panel on Climate Change (IPCC) was established in 1988 by the United Nations Environment Programme (UNEP) and the World Meteorological Organization (WMO). Its creation came in response to growing global awareness and scientific consensus about climate change and the potential impacts of human activities on the Earth’s climate system. The primary purpose of the IPCC is to provide governments with scientific assessments on climate change to inform policy-making.
Structure and Functions
Organizational Structure
The IPCC is composed of three working groups and a task force:
- Working Group I: Deals with the physical science basis of climate change.
- Working Group II: Focuses on climate change impacts, adaptation, and vulnerability.
- Working Group III: Concentrates on climate change mitigation.
- Task Force on National Greenhouse Gas Inventories (TFI): Develops methodologies for measuring emissions and removals of greenhouse gases.
Functions
- Reviewing and Assessing Literature: The IPCC reviews and assesses thousands of scientific papers published each year to provide comprehensive updates on the state of knowledge on climate change.
- Publishing Assessment Reports: The IPCC publishes major assessment reports roughly every five to seven years, along with special reports and technical papers on specific topics.
- Informing Policy Makers: While the IPCC itself does not conduct original research, it synthesizes findings to inform and guide climate policy discussions and decisions globally.
Key Reports and Events
Assessment Reports
The IPCC has published six Assessment Reports (AR1-AR6) as of the last update, each providing a comprehensive summary of climate science knowledge, potential impacts, and strategies for mitigation and adaptation.
Special Reports
In addition to its assessment reports, the IPCC produces special reports on specific issues, such as the Special Report on Global Warming of 1.5°C (SR15) and the Special Report on Climate Change and Land (SRCCL).
Influential Summaries
Summary for Policymakers (SPM)
Each major IPCC report includes a Summary for Policymakers (SPM), distilling the scientific findings into a more accessible format for political and decision-making stakeholders.
Key Concepts and Theories
Climate Change and Global Warming
- Climate Change: Refers to significant changes in global temperatures and weather patterns over time. While climate change is a natural phenomenon, recent trends have been accelerated by human activities.
- Global Warming: Specifically denotes the ongoing increase in global average surface temperatures.
The Hockey Stick Graph
One of the most famous visuals in climate science, the Hockey Stick Graph, demonstrates the sharp increase in global temperatures in recent decades. It was first highlighted in IPCC’s Third Assessment Report (TAR) and has been both influential and controversial.

Importance and Applicability
The IPCC’s work is crucial in forming the backbone of global climate policy. Its assessments influence international agreements like the Kyoto Protocol and the Paris Agreement, guiding nations toward sustainable practices to combat climate change.
Examples and Applications
Policy Influence
- Paris Agreement (2015): IPCC reports provided the scientific basis for the goals set in the Paris Agreement, particularly the ambition to limit global warming to well below 2°C above pre-industrial levels.
National Strategies
- Nationally Determined Contributions (NDCs): Many countries’ climate action plans are based on IPCC assessments.
Considerations and Controversies
Criticisms and Controversies
- Policy Neutrality: While the IPCC aims to be policy-neutral, it has been critiqued for allegedly promoting certain policy agendas.
- Research Verification: The IPCC does not conduct independent research, leading to debates about its ability to fully verify the data it reviews.
Related Terms
- Climate Change: Long-term alteration of temperature and typical weather patterns in a place.
- Global Warming: The long-term heating of Earth’s climate system observed since the pre-industrial period.
- Greenhouse Gas Emissions: Gases that trap heat in the atmosphere, leading to global warming.
Comparisons
- IPCC vs. UNFCCC: While the IPCC provides scientific assessments, the United Nations Framework Convention on Climate Change (UNFCCC) focuses on negotiating and implementing international climate policies.
Interesting Facts
- Nobel Peace Prize: The IPCC, along with Al Gore, was awarded the Nobel Peace Prize in 2007 for its efforts to build up and disseminate greater knowledge about man-made climate change.
Inspirational Stories
The Role of Youth
The IPCC’s findings have inspired a generation of young climate activists, such as Greta Thunberg, to demand urgent action against climate change.
Famous Quotes
- “We are the first generation to feel the impact of climate change and the last generation that can do something about it.” - Barack Obama
Proverbs and Clichés
- Proverb: “We do not inherit the Earth from our ancestors; we borrow it from our children.”
- Cliché: “Think globally, act locally.”
Expressions
- “Climate Emergency”: Highlighting the urgent need to address climate change.
Jargon and Slang
- [“Carbon Footprint”](https://financedictionarypro.com/definitions/c/carbon-footprint/ ““Carbon Footprint””): The total amount of greenhouse gases emitted by an individual or organization.

Summary
The IPCC plays a crucial role in synthesizing scientific knowledge on climate change and informing global policy. While it does not conduct original research, its comprehensive reviews and assessments have significantly influenced international climate policies and agreements. Despite some controversies, its work continues to be a cornerstone in the global fight against climate change.
