I enrolled at Harvard University during the pre-monsoon season, enduring the oppressive heat. Professor Dan Schrag visited Delhi, India, to speak at the climate conference in March 2025.
The temperature soared past 30℃ (86 °F) – a sign of the impending summer, a season where many in the country live without air conditioning, as highlighted by Schrag.
Last summer, the city’s temperature peaked at 52℃ (126 °F) – a level Schrag describes as “insane.”
Interestingly, recent studies indicate that India is warming at a slower pace compared to the global average.
Despite experiencing temperatures in the mid-40s Celsius (110-117 °F) regularly, the average temperature in India has risen by less than 0.9 °C (1.62 °F) since the early 20th century. In contrast, the planet as a whole has warmed by 1.4 °C (2.5 °F) in under 50 years since 1980.
This disparity is depicted in a NASA map, where India appears less affected by rising temperatures than other regions of the world.
This phenomenon has been dubbed a “warming hole,” with potential causes like intensive irrigation and air pollution being explored to explain India’s unique climate trend.
Experts suggest that irrigation, which leads to evaporation and cooling, and air pollution, which reflects sunlight and curbs warming, could be mitigating factors in India’s slower warming.
A lesser-known theory involves CO2 triggering cloud formation through complex geographical processes, potentially offsetting warming effects in India.
While the exact cause of India’s unique climate behavior remains uncertain, the implications of the warming hole call attention to complex environmental interactions that may be disguising the true impact of global warming in the region.
It is essential to address factors such as air pollution and irrigation to understand and potentially mitigate the environmental consequences in India. As the world grapples with escalating temperatures, India’s distinct climate trend presents an intriguing area for further research and action.
