- A The IPCC itself is sometimes thought to conduct its own original primary climate research in-house, operating dedicated research laboratories, weather satellites, and ground-based field stations worldwide
- B IPCC (1988): assesses and synthesizes peer-reviewed climate science for policymakers across three Working Groups; does not conduct original research but provides authoritative assessment of existing evidence
- C The IPCC is sometimes thought to publish mainly national-level policy documents intended mainly for individual member government legislatures to formally adopt at their own discretion
- D IPCC scientific recommendations are sometimes thought to carry full, legally binding enforcement force over every signatory member nation under established international treaty law
Correct answer: B. IPCC (1988): assesses and synthesizes peer-reviewed climate science for policymakers across three Working Groups; does not conduct original research but provides authoritative assessment of existing evidence
Explanation: IPCC: 195 member governments + 1000s of volunteer scientists synthesize global climate literature. Reports: AR1-AR6 (Assessment Reports), Special Reports (1.5C, Oceans, Land). AR6 (2021): 'unequivocal that human influence has warmed the atmosphere, ocean and land'; 1.5C may be exceeded by 2040 under current policies; impacts are accelerating. IPCC reports inform UNFCCC negotiations (Paris Agreement). Not politically independent of governments (Summary for Policymakers is line-by-line government approved).
