Raghu Murtugudde, a professor of climate studies at IIT Bombay, cautioned that excessive communication and activism around climate science can be a distraction to scientists, and they should still do what they are paid to do: the science. “My worry is that a little climate knowledge tends to lead to a massive saviour complex,” he said. Karthik Ganesan, a researcher who works in policy research at the intersection of energy consumption and environmental impacts at the Council of Energy, Environment and Water (CEEW), has a different view.
