25:16 It's the sun that's the dominant factor and continues to be. This chart here, what you see in blue, blue is the average global temperature going back 600000000 years ago here on Earth. In black, the black line is atmosphere carbon dioxide. 2 things stand out in this chart. First of all, is that there is no correlation whatsoever between atmosphere carbon dioxide and global temperatures.
25:42 I mean, you can't find that anywhere. Secondly, just importantly just as importantly, and as you'll see in the black line on the far right where we are today, our atmosphere is absolutely starved of carbon dioxide. The amount of carbon dioxide that we've added to the atmosphere brings our current levels to about 420 parts per million. Scientists tell us that before the industrial revolution, the atmosphere carbon dioxide level was anywhere between a 180 parts per million to 280 parts parts per million. That's where it had bottomed out.
