2 00:00:10,120 --> 00:00:14,210 Storms are expected to intensify in a warmer world, 3 00:00:14,210 --> 00:00:19,460 because water vapor is kind of like the Nitroglycerin of the atmosphere. 4 00:00:19,460 --> 00:00:20,900 Have you ever seen those cowboy movies 5 00:00:20,900 --> 00:00:22,730 where they've got the stagecoach full 6 00:00:22,730 --> 00:00:26,560 of nitro that they're going to use to do some mining or something like that? 7 00:00:26,560 --> 00:00:28,800 And they gotta carry it around without shaking 8 00:00:28,800 --> 00:00:30,880 it too much, because it could just blow up. 9 00:00:30,880 --> 00:00:35,560 Well, water vapor is kind of the same way. Water vapor, when it condenses, 10 00:00:35,560 --> 00:00:39,470 releases latent heat which then drives motion 11 00:00:39,470 --> 00:00:42,520 that drives more water vapor to condense. 12 00:00:42,520 --> 00:00:47,427 And so, all of the explosive weather that we have is due to water vapor. 13 00:00:47,427 --> 00:00:49,507 And as I said before, in a warmer world 14 00:00:49,507 --> 00:00:52,268 there will be more water vapor in the atmosphere. 15 00:00:52,268 --> 00:00:56,947 That tends to make the weather stormier.
