Bhubaneswar: With Odisha’s Capital City now ruling as the hottest city in the country, and when the setting in of hot day conditions in the winter (January – February is regarded as winter by IMD) has sparked a debate over Odisha growing warmer, the big fact to the fore is Odisha has indeed grown warmer in the last 100-years, but only in parts.
