Intergovernmental Panel on Climate Change

The Intergovernmental Panel on Climate Change (IPCC) is an intergovernmental body of the United Nations tasked with assessing the science related to climate change. Established in 1988 by the World Meteorological Organization (WMO) and the United Nations Environment Programme, the IPCC provides comprehensive assessments of current scientific understanding of climate change, its impacts, and potential adaptation and mitigation strategies.

Structure and Function

The IPCC is structured around Working Groups and a Task Force. The Working Groups focus on different aspects of climate change:

Working Group I deals with the physical science basis of climate change, assessing information on climate processes.
Working Group II focuses on impacts, adaptation, and vulnerability, evaluating the impact of climate change on natural and human systems.
Working Group III is tasked with evaluating options for mitigating climate change by reducing greenhouse gas emissions.

The Task Force on National Greenhouse Gas Inventories develops methodologies for countries to calculate and report their greenhouse gas emissions.

Reports and Contributions

The IPCC's main activity is the preparation of comprehensive Assessment Reports, which present the state of scientific, technical, and socio-economic knowledge on climate change. These reports are the result of a rigorous process involving hundreds of scientists from around the world and are reviewed by governments and experts. The latest in this series is the Sixth Assessment Report.

In addition to the Assessment Reports, the IPCC produces Special Reports on specific climate-related topics, like the impacts of global warming of 1.5°C above pre-industrial levels, and Methodology Reports that provide guidelines for preparing greenhouse gas inventories.

Impact and Influence

The work of the IPCC is critically important in informing international and national policy on climate change. Its assessments are used by policymakers to make informed decisions on climate-related issues. The IPCC reports played a pivotal role in the development of the Kyoto Protocol and the Paris Agreement.

The IPCC has been recognized for its contributions to climate science and policy. In 2007, it was awarded the Nobel Peace Prize alongside Al Gore for their efforts to build up and disseminate greater knowledge about man-made climate change.

Current Leadership

As of the latest update, James Skea, a British academic, serves as the Chair of the IPCC. He leads the body in its seventh assessment cycle, focusing on integrating new scientific findings into upcoming reports.

Challenges and Criticisms

Despite its critical role, the IPCC has faced criticisms regarding the complexity of its reports and the long duration between assessments. However, its rigorous review process and comprehensive approach ensure the credibility and reliability of its findings.
