Which of the following statements is/are CORRECT with regards to the report prepared by Climate Central about Climate Shift Index(CSI)?
1. Kerala, Puducherry and Andaman and Nicobar Islands experienced, more than three degrees higher temperatures, among the highest in the world, from June to August, 2023.
2. The report uses the Climate Shift Index (CSI) to compare observed or forecast temperatures to models that account for human-caused climate change.
3. It states that these regions witnessed more than 60 days at CSI level 3 or higher, indicating the impact of climate change.
4. Five Indian states had a summer average CSI above 3.
​

Correct option is D

​The correct answer is (d) 1, 2, 3 and 4

Explanation:

• The Climate Shift Index (CSI) report prepared by Climate Central for the period June to August 2023 highlighted the significant impact of climate change on temperatures in various regions, including parts of India.
• The report utilized the CSI to compare observed temperatures with models accounting for human-caused climate change, providing a clear picture of how climate change is influencing local climates.​

Key Findings from the CSI Report:

• Regions Affected:Kerala, Puducherry, and the Andaman and Nicobar Islands experienced temperatures more than three degrees higher than historical averages, among the highest in the world during this period. ​
• CSI Levels: These regions witnessed more than 60 days at CSI level 3 or higher, indicating that human-caused climate change made these temperatures at least three times more likely.
• Summer Average CSI:Five Indian states had a summer average CSI above 3, reflecting the widespread impact of climate change on local temperatures. ​

Information Booster:

Understanding the Climate Shift Index (CSI):

• Purpose: The CSI quantifies the influence of human-caused climate change on local daily temperatures, providing a clear indication of how climate change is affecting specific regions. ​
• Scale: The CSI ranges from -5 to +5, with positive values indicating that the observed temperature is more likely due to climate change. ​
• Global Impact: During the June-August 2023 period, approximately 7.95 billion people, or 98% of the global population, experienced temperatures that were made at least two times more likely by climate change. ​
