Spring season ‘disappearing’ in many States, shows study
- Analysis of records since 1970 reveals increased warming between Dec. and Feb. across country; at 2.3 degrees Celsius
- Manipur records the biggest jump in temperature in the winter months
Key Highlights
- Indian States have been gradually registering a withdrawal of spring, a period of relatively benign weather between the winter of January and the scorching summer of April
- a 50-year analysis of meteorological records suggests.
Significant trend
- Every region analysed had a ‘net warming’ during winter.
- Meteorologists have earlier ascribed the warming of winter in South India and the lack of rainfall in the North in winter due to
- an aberration in the pattern of Western Disturbances and the jet stream, winds that originate in the Mediterranean and bring moisture to North India during winter.
Climate Change:
- Since 1880, the average global temperature has risen by 1.1°C, of which the majority of warming has happened after 1975 (NASA GISS).
- The current international agenda as reflected in the Paris Accord is to limit the warming to 1.5°C from pre-industrial levels to secure a livable future for all.
- A 2°C rise will set a chain of irreversible reactions in Earth's climate.
- Despite the scientific community and activists pushing for long to take climate action, a lack of political will, institutional changes and industry accountability have kept us way beyond the target.
- At current policy rates, we are projected to reach a 2.8°C rise by 2100.
