IITM Warns of Increasing Floods and Landslides Amid Climate Change
Pune, 18th March 2025: “In recent years, there has been a significant increase in heavy rainfall events. It has been observed that intense downpours occur within a short period, leading to floods and landslides.
Greenhouse gas emissions are contributing to global warming, which must be considered while making long-term weather forecasts. Research is being conducted in this regard, and the Indian Meteorological Department (IMD) is also working in this direction. A model called the Unified Earth System is being developed,” said Dr. R. Krishnan, Director of the Indian Institute of Tropical Meteorology (IITM).
Dr. Krishnan was speaking to reporters on Monday at a workshop organized by IITM. He stated, “It is difficult to provide long-term weather forecasts without considering climate change. While forecasting, it is challenging to predict heavy rainfall events occurring within a short duration accurately. However, such events can be anticipated two days in advance, allowing the IMD to issue timely warnings. Despite this, the increasing frequency of extreme rainfall poses challenges such as waterlogging, particularly in urban areas. The intensity of rainfall is also rising due to global warming. Even though total rainfall levels are increasing, emphasis must be placed on water conservation efforts.”
He further highlighted the impact of urbanization on temperature trends. “In some parts of Pune, maximum temperatures have been recorded higher in recent years. This phenomenon is linked to the formation of urban heat islands caused by rapid urbanization. To study this impact, a research initiative on urban meteorology has been launched. Initially, the focus will be on studying Delhi’s weather patterns. Detailed observations are essential for understanding urban heat islands. Infrastructure is being developed in Delhi to assess the effects of urbanization systematically,” Dr. Krishnan added.
