“Global warming is one of the major reasons behind this phenomenon. However, the year also depends on year to year phenomenon,” said S Pai, a Long Range Forecast scientist with the IMD.
M Rajeevan, Secretary, the Ministry of Earth Sciences, also cited global warming as a major reason for a milder winter.
IMD has said that 2016 has been one of the hottest years since 1901.
Pai, however, said that several other local factors have impacted temperatures in northern India.
