Article summary
The IPCC Sixth Assessment Report (AR6) Synthesis, released in March 2023, concluded that global surface temperature has already risen 1.1°C above 1850–1900 levels and that limiting warming to 1.5°C requires net-zero CO2 emissions globally by 2050. The report found that even at 1.5°C, South Asia faces increased heat wave frequency, disrupted monsoon patterns, sea level rise threatening 40 million coastal Indians, and significant crop yield losses. The report identified a widening adaptation finance gap — developing countries need $127–300 billion annually by 2030 but are receiving less than $50 billion.
What this tests
Sample questions — answers revealed after test
Q1. The Loss and Damage Fund, which addresses irreversible climate impacts beyond adaptation capacity, was established and subsequently operationalised at which pair of COPs respectively?
Q2. A policy brief argues: 'India's updated NDC commitments are intensity-based, not absolute, and therefore structurally inadequate to meet the 1.5°C pathway.' Which of the following, if true, would MOST directly support this argument?
Q3. Consider the following statements about IPCC AR6 and the global climate architecture: 1. IPCC AR6 consists of reports from three Working Groups — Physical Science Basis, Impacts and Adaptation, and Mitigation — integrated into a Synthesis Report, and was published between 2021 and 2023. 2. The 1.5°C temperature target in the Paris Agreement was originally proposed by the European Union as a compromise between the more ambitious demands of small island states and the 2°C ceiling sought by major emitters. 3. At current national pledges (NDCs), global average temperature is projected to rise by 2.5–2.9°C by 2100, indicating a significant ambition gap relative to both Paris Agreement goals. 4. IPCC shared the 2007 Nobel Peace Prize with Al Gore and has 195 member governments, but does not conduct original research — it synthesises peer-reviewed scientific literature. How many of the above statements are correct?
