KATHMANDU, Jan 18: Amid forecast of the US-based National Aeronautics and Space Administration (NASA) that the smoke from Australia's fires will make a full circuit around the world, there are concerns around the world if this would leave impact on other countries as well. Meteorologists and atmospheric scientists in Nepal, however, say there is no need to panic although there are some chances of receiving slightly visible effects in the sky over this Himalayan nation should the fire keep on razing at a dangerous pace.
