Climate change needs to be tackled at the policy level and at the level of implementation. BE’s Kishore Biswas spoke to Professor Jayanta Bandyopadhay, an expert on various climate change issues, who is currently a Distinguished Fellow at the Observer Research Foundation, Kolkata.

Q. People talk about the dangers of global warming. Can you please explain the real issue?

A. Thank you for raising this topic. Let me first clarify that there is a need to straighten the causal links related to global warming. A fundamental change has been noticed in the measured annual average temperature at the surface of the Earth. This growth in annual average temperature has been noticed since the systematic measurement of atmospheric temperature had been initiated.

This systematic upward movement of atmospheric temperature is now called global warming. However, changes in the temperature of the surface of the Earth are not new. Temperature of the Earth’s surface has varied based on factors like changes in the amount of energy reaching the Earth from the Sun and also based on the variation in the distance of our planet from the Sun. As a result, the Earth has seen periods of glaciation and as well as heating.
