IPCC
A United Nations scientific body responsible for assessing climate change and providing policy recommendations. Its primary functions are consensus-building and information sharing; it holds no enforcement authority. The IPCC is cited as a potential reference model for intergovernmental AI governance organizations.
Timeline (last 90 days)
The gap between 1.5°C and 2°C of warming corresponds to significant deterioration in key indicators such as coral reef survival rates, extreme heat wave frequency, and sea level rise, based on scientific assessments from the IPCC.
Under a 1.5-degree warming scenario, approximately 14% of the global population will experience extreme heat at least once every five years.
Under a 2-degree warming scenario, the proportion of the population experiencing extreme heat at least once every five years will jump to 37%.
Multiple IPCC reports indicate that there are significant nonlinear differences between 1.5°C and 2°C in terms of impacts on ecosystems, sea level rise, frequency of extreme weather events, and food security.
Since its establishment in 1988, the IPCC has published six assessment reports, and its Sixth Assessment Report (AR6) is the first to systematically include cities as a standalone chapter in its analysis.
The IPCC Sixth Assessment Report states that approximately 70% of global carbon emissions originate from cities.
The climate risk analysis model established in the IPCC Fifth Assessment Report is: Risk = Hazard × Exposure × Vulnerability.
根据IPCC评估，核电全生命周期碳排放强度约为12克二氧化碳当量/千瓦时，远低于天然气发电（约490克）和煤电（约820克）
