Researchers at IIT-Madras come up with climate model for Indian regions

The Hindu  

Researchers at the Indian Institute of Technology-Madras have suggested the use of a multimodal approach to quantify climate model uncertainty. The approach offers reliable climate change estimates and quantifies uncertainty among models crucial for informed climate planning and management. The REA model is used to address critical challenges in climate modelling in monsoon-prone regions such as India, offering valuable insights for climate change projections, he said. “The approach provides more dependable estimates of climate change variables and effectively quantifies uncertainty among diverse models, which is pivotal for making informed decisions in climate-related planning and management,” Mr. Mohan said. Based on the latest IPCC report, the ensemble of 26 global climate models was used to evaluate the possible change in seasonal precipitation in Coimbatore, Rajkot, Udaipur, and Siliguri, cities with distinct climate conditions.

There isn’t much climate change denial in India, for which we must give thanks. This is a heatwave that’s certainly been exacerbated by rising global temperatures—the world is, after all, 1.2 degree Celsius hotter and India is nearly 1 degree Celsius hotter than in pre-industrial times. And particularly in the coastal areas and in the Indo-Gangetic plains, the humidity also …
