freezing temperatures, that s a challenge. even though there are tens of thousands of firefighters fighting the blaze s around this part of russia, they re not going to bring them under control until the weather changes. and in moscow, that s what it looks like, but that is an improvement over what it was on saturday and sunday. yes. so we should be grateful, shouldn t, we, for these small mercies. but it s pretty awful. the smokes has permeated office buildings and my apartment. it s terrible when you wake up in the morning. even in the metro system in this city, which is very deep underground, one of the deepest in the world, people are complaining that the smoke is pungent down there, as well. matthew chance in moscow, thanks very much. nature s wrath not just in russia, here in the united states, in minnesota over the weekend, a storm chaser catches a tornado destroying a farmhouse. listen to his emotional reaction. that s today s sound effect. oh, it hit that no!
