IPCC: A Comprehensive Guide to the Intergovernmental Panel on Climate Change


The Intergovernmental Panel on Climate Change (IPCC) is a scientific body established in 1988 by the World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP). The IPCC is responsible for assessing the science related to climate change, its impacts, and possible mitigation and adaptation measures. This article provides a comprehensive guide to the IPCC, its history, structure, and key findings.

History of IPCC:

The idea for the IPCC was first proposed in the mid-1980s by the WMO and UNEP in response to growing concerns about global climate change. The IPCC was officially established in 1988 with the mandate to assess the state of knowledge on climate change and provide scientific advice to policymakers. Since then, the IPCC has produced a series of assessment reports, special reports, and technical papers that have become a cornerstone of climate science and policy.

Structure of IPCC:

The IPCC is composed of three working groups, a task force, and a secretariat. The working groups are responsible for assessing the physical science of climate change, the impacts of climate change, and the mitigation and adaptation options, respectively. The task force is responsible for greenhouse gas inventories and the development of methodologies for assessing emissions and removals. The secretariat provides administrative and logistical support to the IPCC.

Mission Statement of IPCC

The IPCC’s mission statement is to “provide scientific information that can be used by policymakers and other stakeholders to make informed decisions about how to address the challenge of climate change.” The organization aims to assess the latest scientific findings on climate change and its impacts, and to provide objective, transparent, and rigorous assessments of the risks and opportunities associated with different policy options.

The IPCC is committed to working collaboratively with governments, scientific organizations, and civil society to ensure that its assessments are comprehensive, balanced, and impartial. The organization also seeks to promote public awareness and understanding of climate change and its impacts, and to facilitate international cooperation in addressing this global challenge.

Assessment Reports:

The IPCC produces assessment reports every 6-7 years that provide a comprehensive summary of the state of climate science. These reports are widely regarded as the most authoritative source of information on climate change. The IPCC’s Fifth Assessment Report, released in 2014, provided the clearest and most detailed picture yet of the causes, impacts, and solutions to climate change.

Special Reports:

In addition to assessment reports, the IPCC also produces special reports on specific topics related to climate change. These reports are usually requested by governments or other organizations to provide more in-depth analysis on a particular issue. Recent special reports include the Special Report on Global Warming of 1.5°C, which assessed the impacts of global warming at 1.5°C and the pathways to limit it, and the Special Report on Climate Change and Land, which assessed the interactions between climate change and land use.

Key Findings:

The IPCC has produced a vast body of scientific evidence on climate change. Key findings include:

  • The Earth’s climate is warming, and human activities, particularly the burning of fossil fuels, are the primary cause of this warming.
  • The impacts of climate change are already being felt around the world, and these impacts will become more severe and widespread if greenhouse gas emissions are not reduced.
  • Limiting global warming to 1.5°C would require rapid and far-reaching transitions in energy, land, urban, and infrastructure, and industrial systems.
  • Adaptation measures are necessary to address the impacts of climate change that are already unavoidable.


The IPCC plays a crucial role in providing policymakers with the scientific evidence needed to address the complex and urgent issue of climate change. Its assessments and reports have helped to shape the international response to climate change and provide the foundation for the Paris Agreement. As the world faces ever-increasing climate-related challenges, the IPCC will continue to be a vital source of information and guidance.Keywords: IPCC, climate change, assessment reports, special reports, global warming, greenhouse gas emissions, adaptation measures, Paris Agreement.
