What is the News ?

During the Little Ice Age (LIA), the Western Ghats in India bore the hallmark of moist conditions, according to a recent study.

Facts About:

  • It revealed significant variations in rainfall patterns during that time period, challenging the conventional view of the Little Ice Age (LIA) as a uniformly cold and dry climate with reduced monsoon rainfall.
  • It was proposed that the Inter Tropical Convergence Zone's (ITCZ) northward motion, positive temperature anomalies, an increase in the number of sunspots, and high solar activity may be responsible for climate change and an accelerated South West Monsoon.
  • In general, they believed that the southward shift of the ITCZ, which was brought on by increased northward energy flux across the equator during a cold northern hemisphere, was to blame for the weakest phase of the Indian Summer Monsoon (ISM) across the Indian subcontinent during the Little Ice Age.
  • The high-resolution palaeoclimatic records produced in the current study may be useful in developing paleoclimatic models for future climatic predictions as well as for scientifically sound policy planning.
  • In order to better understand the current Indian Summer Monsoon (ISM)-influenced climatic conditions as well as potential future climatic trends and projections, knowledge and understanding of climate change and Indian Summer Monsoon (ISM) variability during the Holocene could be of immense interest.

About the Little Ice Age:

  • The Little Ice Age, which began in the late 19th and early 20th centuries, came after the Mediaeval Warming Period (roughly 900–1300 CE) and came before the current warming period.
  • It was one of the coldest times in the last 10,000 years, with the North Atlantic region experiencing the greatest cooling.
  • Millions of people suffered and died as a result of this cold spell, whose precise timing scholars debate but which appears to have begun around 600 years ago.

              It is thought to have been the cause of crop failures, famines, and pandemics throughout Europe.
