Introduction

The Intergovernmental Panel on Climate Change (IPCC) has been a cornerstone in the global effort to understand and combat climate change. Established in 1988, this body of experts assesses the vast body of scientific literature to provide comprehensive reports on the state of climate science. These reports are crucial in guiding international climate policies and strategies.

Climate change represents one of the most significant challenges of our time. Rising global temperatures, melting polar ice, and increasing frequency of extreme weather events are just a few indicators of this pressing issue. Understanding these changes and their potential impacts requires a coordinated, global effort—one that the IPCC leads with scientific rigor and dedication.

History and Formation of IPCC

The IPCC was established by the United Nations Environment Programme (UNEP) and the World Meteorological Organization (WMO) to provide policymakers with regular assessments of the scientific basis of climate change, its impacts and future risks, and options for adaptation and mitigation. This move was prompted by growing concerns over the potential long-term consequences of anthropogenic climate change and the need for authoritative scientific guidance.

Since its inception, the IPCC has produced a series of assessment reports, special reports, and methodological guidelines that have shaped global climate discourse. Each report builds upon the previous ones, reflecting the evolving understanding of climate science.

IPCC Structure and Working Groups

The IPCC’s work is divided among three working groups and a Task Force:

• Working Group I: Examines the physical science basis of climate change, including atmospheric, oceanic, and cryospheric processes.

• Working Group II: Focuses on the impacts of climate change, as well as vulnerability and adaptation measures.

• Working Group III: Deals with mitigation strategies, exploring ways to reduce greenhouse gas emissions and enhance carbon sinks.

• Task Force: Specializes in national greenhouse gas inventories, providing methodologies and guidelines for countries to measure and report their emissions.

Each working group consists of experts from various disciplines, ensuring a comprehensive and multidisciplinary approach to climate change assessment.

Major Reports and Findings

The IPCC’s assessment reports are among the most influential scientific documents on climate change. They synthesize findings from thousands of peer-reviewed studies, providing a clear and concise overview of the current state of knowledge.

First Assessment Report (1990): Laid the groundwork for international climate policy by highlighting the potential impacts of climate change. It played a crucial role in the establishment of the United Nations Framework Convention on Climate Change (UNFCCC).

Second Assessment Report (1995): Contributed to the development of the Kyoto Protocol by providing evidence of human influence on the global climate.

Third Assessment Report (2001): Strengthened the understanding of climate change impacts and introduced the concept of “dangerous anthropogenic interference” with the climate system.

Fourth Assessment Report (2007): Confirmed that global warming is unequivocal and largely driven by human activities. This report, along with Al Gore’s work, led to the IPCC being awarded the Nobel Peace Prize.

Fifth Assessment Report (2014): Provided detailed insights into the impacts of climate change on natural and human systems. It emphasized the need for urgent action to mitigate and adapt to climate change.

Sixth Assessment Report (2021-2022): Offered the latest scientific findings, including new information on climate sensitivity, carbon budgets, and regional impacts.

Special reports, such as the Special Report on Global Warming of 1.5°C (SR15) and the **Special Report on Climate Change and Land (SRCCL
