Little Ice Age

Facts for Prelims (FFP)

 Context: A new study of the Little Ice Age (LIA), a global climatic event from 1671-1942, challenges the traditional perception of it being uniformly cold and dry.

• The study, reconstructed the climate history of the Western Ghats in India between 1219 and 1942 using pollen-based vegetation data.

Key Findings:

• The findings suggest that the LIA was not uniformly cold and dry but instead had significant variations in rainfall patterns.
• The study points to the influence of the northeast winter monsoon (NEM) in creating a “moist” or “wet” LIA in the region.
• The research also highlights the impact of factors like the northward movement of the Inter Tropical Convergence Zone (ITCZ), positive temperature anomalies, increased sunspot numbers, and high solar activity on climate changes during the LIA.

This information can aid in developing paleoclimatic models for future climate predictions and policy planning, helping to understand the Indian Summer Monsoon (ISM) and its variability during the Holocene
