WEBVTT 00:00:28.880 --> 00:00:34.425 (Sound of iceberg crumbling and running into the ocean) 00:00:49.545 --> 00:00:53.770 What you just witnessed was an iceberg about the size of Manhattan 00:00:53.780 --> 00:00:58.440 breaking off a cliff in Greenland to drift out and melt into the ocean. 00:00:59.600 --> 00:01:02.890 The Arctic region is melting as it's heated twice as fast 00:01:02.890 --> 00:01:04.510 as the rest of the planet, 00:01:04.510 --> 00:01:08.210 and science every day brings us news, alarming news, from the North. 00:01:08.210 --> 00:01:11.810 Science tend to always bring us bad news from the North. 00:01:12.050 --> 00:01:14.100 Just yesterday it was announced 00:01:14.100 --> 00:01:17.750 that this April is the warmest we've ever experienced. 00:01:17.750 --> 00:01:19.930 In certain parts of Greenland, 00:01:19.930 --> 00:01:23.209 it was not one degree warmer, not two degrees warmer, 00:01:23.209 --> 00:01:27.150 it was nine and a half degrees warmer than normal April's would be. 00:01:27.990 --> 00:01:34.630 So I think the Arctic has become a symbol of global change and pending disaster. 00:01:35.850 --> 00:01:39.590 I was myself born in Greenland a very long time ago. 00:01:40.390 --> 00:01:45.410 I came from Greenland to Denmark and the U.S. to become a scientist, 00:01:45.410 --> 00:01:49.550 to study geology with the one purpose of being able to come back 00:01:49.550 --> 00:01:55.180 and do my fieldwork every summer in the vast Arctic nature. 00:01:56.290 --> 00:01:58.750 I think it's kind of misleading 00:01:58.750 --> 00:02:03.970 that the Arctic has gotten this emblem of being a symbol of disaster 00:02:03.970 --> 00:02:08.249 because the reason why we, as scientists, go into the Arctic 00:02:08.249 --> 00:02:12.020 is because the Arctic is the most wonderful region on the planet. 00:02:12.750 --> 00:02:15.640 It is the most beautiful place and every scientist I know, 00:02:15.640 --> 00:02:19.160 they go to the Arctic with that one particular reason: 00:02:19.170 --> 00:02:21.030 to be in this beautiful place. 00:02:21.030 --> 00:02:24.560 In contrast to what we see, those of us who live in the Arctic, of course, 00:02:24.560 --> 00:02:28.880 industries see another property of the Arctic: they see opportunity. 00:02:28.880 --> 00:02:32.110 The heating of the Arctic is supposed to give access 00:02:32.110 --> 00:02:36.959 to new mineral resources; oil, gas, gold, fish, whatever, 00:02:36.959 --> 00:02:39.959 and the business plan seems to be, 00:02:40.589 --> 00:02:44.489 "Let us go and exploit and scavenge the last drop of everything 00:02:44.489 --> 00:02:47.310 that is left in that last place on Earth 00:02:47.310 --> 00:02:50.190 that has not yet been destroyed by humankind." 00:02:50.680 --> 00:02:53.960 I think the question that I would like to pose today is: 00:02:54.520 --> 00:02:56.919 Is that really the best idea we can come up with 00:02:56.919 --> 00:02:59.669 and do exactly the same that has destroyed everywhere else 00:02:59.680 --> 00:03:02.500 in the last place that has not been destroyed yet? 00:03:03.690 --> 00:03:08.490 My suggestion is that we cannot risk to do those vast expanses 00:03:08.490 --> 00:03:11.110 of undestroyed nature that the Arctic still possesses, 00:03:11.110 --> 00:03:16.450 and we have to use our research capacity to try and come up with something 00:03:16.450 --> 00:03:21.480 that is more smart, and more sustainablem and more long-term benefit for mankind. 00:03:21.700 --> 00:03:25.080 I suggest that instead of doing what we had done everywhere else, 00:03:25.080 --> 00:03:26.880 we should do something new, 00:03:26.880 --> 00:03:30.940 and we should find out what are the true values of the Arctic. 00:03:32.750 --> 00:03:35.420 I have a specific suggestion, 00:03:35.830 --> 00:03:42.200 a method that I think could be a way of using the melting of the Arctic region 00:03:42.550 --> 00:03:46.470 to actually fight problems otherwhere on the planet. 00:03:46.470 --> 00:03:51.910 One of the major problems we have beside the climate change, of course, 00:03:51.910 --> 00:03:54.710 is inequality and food security. 00:03:54.710 --> 00:04:00.240 If we look at the wealth on Earth, we know it's unevenly distributed on the planet, 00:04:00.240 --> 00:04:02.350 some regions are rich, some are poor. 00:04:02.350 --> 00:04:06.040 The rich regions, which are not what's shown on this map, 00:04:06.040 --> 00:04:09.040 but could as well have been, this map shows soil quality. 00:04:09.040 --> 00:04:12.440 It shows where the crops that, as coming from the fields, 00:04:12.440 --> 00:04:14.110 are richest on the planet. 00:04:14.110 --> 00:04:18.080 You see that richness couples completely with where the soil was good. 00:04:18.080 --> 00:04:23.840 The reason for this is not that the soil has always been like that, 00:04:23.840 --> 00:04:28.300 it is because the soil was replenished with minerals during the last ice age. 00:04:28.300 --> 00:04:31.100 Ice came down from the north, scoured the rocks, 00:04:31.100 --> 00:04:34.900 turned it into a fine powder and dumped it in front of the glaciers 00:04:34.900 --> 00:04:38.040 and fertilized the grounds across North America, Europe, and Asia, 00:04:38.040 --> 00:04:41.170 and that's where everything that feeds humankind today grows. 00:04:41.410 --> 00:04:44.150 On the other hand, if you look into the tropics, 00:04:44.150 --> 00:04:48.130 you have red barren soils with very poor fertility, 00:04:48.140 --> 00:04:51.580 and that is the reason why people in the tropics are poor, 00:04:51.580 --> 00:04:53.940 why we have malnutrition and undernutrition, 00:04:53.940 --> 00:04:58.190 because these soils are basically impossible to grow crops on. 00:04:58.190 --> 00:05:00.060 My suggestion is very simple. 00:05:00.060 --> 00:05:06.290 In Greenland, where we have the last bit of the ice cap in the Northern Hemisphere, 00:05:06.510 --> 00:05:09.070 and it's melting right now, it's been melting forever, 00:05:09.070 --> 00:05:10.680 but now it's melting faster, 00:05:10.680 --> 00:05:15.220 it's flushing out billions of tons of very finely ground rock flour 00:05:15.220 --> 00:05:18.760 that contains all the mineral nutrients that are missing in the tropics. 00:05:18.770 --> 00:05:23.610 The idea is that we take that mud, this material from Greenland, 00:05:23.610 --> 00:05:27.280 transferred to the tropical regions and spread it on the ground, 00:05:27.280 --> 00:05:31.160 where it will re-fertilize the soil and provide for new wealth 00:05:31.160 --> 00:05:33.110 and new development in these countries. 00:05:33.110 --> 00:05:35.360 At the same time the Arctic region 00:05:35.370 --> 00:05:39.380 is also, of course, needing development and new trades 00:05:39.380 --> 00:05:42.700 but rather than doing the same again as we have done everywhere else, 00:05:42.700 --> 00:05:45.230 we could do something to develop the Arctic 00:05:45.230 --> 00:05:48.870 that at the same time does something good in the rest of the world. 00:05:49.370 --> 00:05:51.890 My suggestion is again that we take the mud 00:05:51.890 --> 00:05:56.150 coming out of the glaciers in Greenland and take it to the tropics, 00:05:56.150 --> 00:05:59.780 because the mud that you find in Greenland is unlike any other mud you find. 00:05:59.780 --> 00:06:03.950 The mud you have in the Amazon, the Mississippi, or any other major river, 00:06:03.950 --> 00:06:08.720 is what's leftover after all the nutrients have been sucked out of the ground, 00:06:08.720 --> 00:06:11.060 and the leftovers are flushed down the river. 00:06:11.060 --> 00:06:16.210 Whereas in Greenland, it has, intact all the minerals 00:06:16.210 --> 00:06:17.960 that plants need to grow in. 00:06:18.940 --> 00:06:23.680 In Greenland this is dumped by the rivers in the fjords, the valleys, and the lakes, 00:06:23.680 --> 00:06:26.960 and it's very easy to take it without making a large industry 00:06:26.960 --> 00:06:29.350 without having any chemical treatment, anything. 00:06:29.600 --> 00:06:34.200 You basically just take up this stuff and take it to where it's needed. 00:06:35.670 --> 00:06:37.690 That, of course, begs a new question: 00:06:37.690 --> 00:06:41.740 Is that really a good idea to take millions of tons of something 00:06:41.740 --> 00:06:45.660 from someplace on Earth and take it to some other part of Earth? 00:06:45.660 --> 00:06:48.100 Isn't that another climate threat? 00:06:48.100 --> 00:06:51.340 Is that not something that's going to make our problem even greater? 00:06:51.340 --> 00:06:54.740 My suggestion is that it's not, because the good news is 00:06:54.740 --> 00:06:57.980 that the mechanism by which the nutrients are released 00:06:57.980 --> 00:07:01.720 from this material to the plants is a process we call "weathering": 00:07:01.720 --> 00:07:04.490 weathering is when something, minerals, 00:07:04.490 --> 00:07:07.360 react the carbon dioxide from the atmosphere. 00:07:07.750 --> 00:07:10.290 We take this, spread it on the tropical soils. 00:07:10.290 --> 00:07:13.700 What happens is that it will start reacting the CO2 from the atmosphere 00:07:13.700 --> 00:07:15.450 and draw it out of the atmosphere. 00:07:15.450 --> 00:07:19.240 We can calculate that by transporting this material 00:07:19.240 --> 00:07:21.400 from the Arctic to the tropics, 00:07:21.400 --> 00:07:25.430 we actually emit less CO2 in the process 00:07:25.430 --> 00:07:30.539 than we consume by the reaction of this material with the atmosphere. 00:07:30.539 --> 00:07:36.829 My suggestion is that Greenlandic glacier mud can be a solution 00:07:36.829 --> 00:07:41.550 to problems like hunger and poverty in the tropics, 00:07:41.560 --> 00:07:43.590 also it will lower the incentive 00:07:43.590 --> 00:07:47.770 to cut rainforest to make new land for agriculture. 00:07:49.410 --> 00:07:50.989 Therefore I will suggest 00:07:50.989 --> 00:07:55.580 that the Arctic could be a source of good news finally. 00:07:56.450 --> 00:07:59.940 I will say that Greenland is not called "Greenland" for nothing, 00:07:59.940 --> 00:08:03.040 it's actually the place that could make parts of the Earth 00:08:03.040 --> 00:08:06.240 that is now barren green as we see Greenland is here. 00:08:06.240 --> 00:08:08.550 So it's time for good news from the North. 00:08:08.550 --> 00:08:11.250 (Applause)
