The increasing frequency and intensity of heatwaves in India are closely linked to climate change. Several factors contribute to this phenomenon:

  1. Rising Global Temperatures:
  • Overview: Global temperatures have been steadily rising due to the increased concentration of greenhouse gases in the atmosphere. The burning of fossil fuels, deforestation, and industrial activities have significantly contributed to this rise. According to the Intergovernmental Panel on Climate Change (IPCC), the average global temperature has already increased by about 1.1°C above pre-industrial levels.

2. Urban Heat Island Effect:

  • Overview: Urban areas tend to be significantly warmer than their rural surroundings due to human activities. This phenomenon, known as the urban heat island effect, is caused by factors such as concrete structures, asphalt roads, and reduced green cover. Cities like Delhi and Nagpur are particularly affected, leading to higher temperatures and prolonged heatwaves.

3. Deforestation and Land Use Changes:

  • Overview: Deforestation and changes in land use patterns have exacerbated the impact of heatwaves. Forests play a crucial role in regulating temperatures by providing shade and facilitating the process of evapotranspiration. The loss of forest cover has led to higher surface temperatures and reduced natural cooling.

4. Water Scarcity:

  • Overview: Heatwaves put immense pressure on water resources. Higher temperatures increase evaporation rates, leading to the depletion of water bodies. Regions like Rajasthan and Uttar Pradesh, already facing water scarcity, are witnessing even more severe shortages, affecting agriculture, drinking water supply, and overall quality of life.
