April 26 recorded the highest temperature for the day during the past 30 years in Kathmandu. The mercury hit a scorching 35.6C, up by 5C compared to the same day last year. Nepal has been suffering an abnormally prolonged dry spell in the past couple of months. Though the threat of global warming already exists, specialists at the department of meteorology and hydrology blame the dry winter as the main reason for the soaring temperature in the Kathmandu Valley this year. The dry conditions have led to forest fires in several areas.
