Explanation

The Intergovernmental Panel on Climate Change (IPCC), particularly in its Sixth Assessment Report (AR6) Synthesis Report (2023), emphasizes that to limit global warming to 1.5°C or 2°C, "deep, rapid and sustained" greenhouse gas (GHG) emission reductions are essential across all sectors. The IPCC highlights that global GHG emissions must peak before 2025 and be reduced by approximately 43% by 2030 to keep the 1.5°C target within reach. Gradual and limited reductions are considered insufficient to meet the goals of the Paris Agreement and would lead to irreversible climate tipping points. Therefore, statement 1 is incorrect as it underestimates the required pace of change, while statement 2 accurately reflects the scientific consensus and the core message of the IPCC regarding the urgency of climate mitigation efforts.
