38:15 And here's what I discovered. Scientists reporting in the peer reviewed journal of geophysical research. They looked at wildfire data glow globally going back to 1901. What they found it is that there has been a quote, notable declining rate of burned area globally for more than a century. So whether we're talking 17 years or a 107 years, we see as temperatures warm, wildfires are becoming less frequent and less severe.
48:29 So, this isn't unusual. We've we've found what they called it. They called it a highway over in, I wanna say Lapland, where for 100 of years, people have been traversing this area, except it was covered with ice for, a couple of 1000 years, because the ice expanded and, and it's now shrunk back to where it was before. Right. And, you know, finally, even in Greenland, you know, they talk about, oh, Greenland ice melting.
