Quick Revision
Approximately 600 experts have started working on the IPCC's Seventh Assessment Report (AR7).
The US President has called climate change a 'hoax' and ordered cuts in climate research funding.
The previous IPCC report (2023) warned that the world was on track to exceed the 1.5°C warming threshold by 2030.
The UN now states that the safer warming limit will be breached earlier than feared.
The AR7 is scheduled for publication in 2028 or 2029.
IPCC reports operate by consensus, meaning any country's opposition can prevent the report's approval.

IPCC Reports, Climate Targets, and Global Urgency
This timeline illustrates the chronological progression of key IPCC reports, the establishment of global warming targets, and the increasing urgency highlighted by recent scientific assessments and political challenges, including the US stance.
The global response to climate change has evolved significantly since the late 20th century, driven by scientific consensus from bodies like the IPCC and international agreements under the UNFCCC. Despite landmark agreements like the Paris Agreement, the urgency of climate action is intensifying as warming thresholds are approached, facing challenges from political pushback and funding cuts.
- 1988IPCC (Intergovernmental Panel on Climate Change) established by WMO and UNEP.
- 1992UNFCCC (UN Framework Convention on Climate Change) adopted at Earth Summit, Rio.
- 1997Kyoto Protocol adopted, setting binding emission targets for developed countries.
- 2007IPCC awarded Nobel Peace Prize jointly with Al Gore.
- 2015Paris Agreement adopted (COP21), aiming to limit warming to well below 2°C, preferably 1.5°C.
- 2023 (March)IPCC's Sixth Assessment Report (AR6) Synthesis Report released, warning world on track to exceed 1.5°C by 2030.
- 2023 (Dec)COP28 in Dubai concludes with agreement to 'transition away from fossil fuels' and operationalizes Loss and Damage Fund.
- 2024 (Current)Work on IPCC's Seventh Assessment Report (AR7) begins; UN suggests 1.5°C limit may be breached even sooner than 2030. US expresses skepticism and orders cuts in climate research funding.
- 2028-2029IPCC AR7 expected to be released, crucial for future climate policy.

Summary
Hundreds of experts have begun work on the Intergovernmental Panel on Climate Change's (IPCC) Seventh Assessment Report (AR7), a crucial scientific assessment for global climate policy. This effort is proceeding even as the United States, under its current administration, has expressed skepticism about climate change and ordered cuts in climate research funding.
The previous IPCC report in 2023 warned that the world is on track to exceed the 1.5°C warming threshold by 2030, and the UN now suggests this limit may be breached even sooner. The AR7, expected in 2028 or 2029, will be vital for informing international climate negotiations, but its consensus-based approval process means any country's opposition can delay or block its publication.
Background
Latest Developments
Work has commenced on the IPCC's Seventh Assessment Report (AR7), a critical scientific document for global climate policy. This is happening amidst political skepticism and funding cuts for climate research by the current US administration.
The previous report (AR6) in 2023 warned that the 1.5°C warming threshold could be exceeded by 2030, with the UN now suggesting an even earlier breach. The AR7, due in 2028-2029, will be vital for informing future climate negotiations, but its consensus-based approval process means any single country's opposition can potentially delay or block its publication.
Practice Questions (MCQs)
1. With reference to the Intergovernmental Panel on Climate Change (IPCC) and its reports, consider the following statements: 1. The IPCC conducts its own primary research on climate change to generate its assessment reports. 2. The Seventh Assessment Report (AR7) is expected to be published by 2029 and will be crucial for informing international climate negotiations. 3. The Paris Agreement aims to limit global warming to well below 2°C, preferably to 1.5°C, above pre-industrial levels. Which of the statements given above is/are correct?
- A.1 and 2 only
- B.2 and 3 only
- C.3 only
- D.1, 2 and 3
Show Answer
Answer: B
Statement 1 is incorrect. The IPCC does not conduct its own research. Instead, it synthesizes and assesses thousands of scientific papers published worldwide to provide comprehensive assessments of climate change. Statement 2 is correct, as per the news article, AR7 is expected by 2028 or 2029 and is vital for climate negotiations. Statement 3 is correct. The Paris Agreement's central aim is to strengthen the global response to the threat of climate change by keeping a global temperature rise this century well below 2 degrees Celsius above pre-industrial levels and to pursue efforts to limit the temperature increase even further to 1.5 degrees Celsius.
2. In the context of international climate governance and the Intergovernmental Panel on Climate Change (IPCC), consider the following statements: 1. The final approval of IPCC Assessment Reports requires a consensus among all member governments, which can potentially delay or block its publication. 2. The principle of Common but Differentiated Responsibilities and Respective Capabilities (CBDR-RC) is a foundational principle explicitly enshrined in the Paris Agreement. 3. The Green Climate Fund (GCF) was established under the UNFCCC to assist developing countries in adaptation and mitigation practices. Which of the statements given above is/are correct?
- A.1 and 2 only
- B.2 and 3 only
- C.1 and 3 only
- D.1, 2 and 3
Show Answer
Answer: C
Statement 1 is correct. As mentioned in the news, the consensus-based approval process for IPCC reports means any country's opposition can delay or block its publication. Statement 2 is incorrect. While CBDR-RC is a foundational principle of the UNFCCC, its application evolved in the Paris Agreement. The Paris Agreement adopted a more nuanced approach, applying CBDR-RC 'in light of different national circumstances' rather than explicitly enshrining it in the same way as the UNFCCC or Kyoto Protocol. All parties are expected to contribute, but with flexibility for developing nations. Statement 3 is correct. The Green Climate Fund (GCF) is a fund established within the framework of the UNFCCC to assist developing countries in adaptation and mitigation practices to counter climate change.
3. Which of the following statements best describes the primary challenge faced by the Intergovernmental Panel on Climate Change (IPCC) in its mission to inform global climate policy, as highlighted by recent developments?
- A.Lack of sufficient scientific data and research to accurately model future climate scenarios.
- B.Inability to attract leading climate scientists due to funding constraints and political interference.
- C.The consensus-based approval process for its reports, which allows political pushback from member states to delay or block publication.
- D.Over-reliance on climate models that consistently overestimate the rate of global warming, leading to skepticism.
Show Answer
Answer: C
Option A is incorrect; the IPCC synthesizes vast amounts of existing research, and the challenge is not a lack of data but rather its interpretation and political acceptance. Option B is generally incorrect; the IPCC attracts top scientists, though funding for *research* (not IPCC itself directly) can be an issue for countries. Option D is incorrect; climate models have generally proven robust, and the issue is political skepticism, not scientific inaccuracy. Option C directly reflects the core challenge highlighted in the news: 'its consensus-based approval process means any country's opposition can delay or block its publication,' exacerbated by 'US pushback on Global Warming Science.'
