About Climate Shift Index (CSI)
- CSI is a model developed by a reputed U.S. nonprofit called Climate Central.
- CSI uses a categorical five-point scale to show how climate change makes daily average temperatures more or less likely around the world.
Determination of Climate Change
- An exercise to determine climate change’s influence on a weather event involves detection and attribution.
- Attribution compares real conditions with counterfactual world where climate change has not occurred.
- Heatwave was detected in UP for June 14-16 period.
- In terms of Attribution, the heatwave was made twice as likely due to global warming.
Problems in CSI
- It does not account for the confluence of multiple natural weather conditions & human decisions that led to a heatwave.
- Poor rainfall data coverage in India can lead to imperfect models.
