1
00:00:28,880 --> 00:00:34,425
(Sound of iceberg crumbling
and running into the ocean)

2
00:00:49,545 --> 00:00:53,770
What you just witnessed was an iceberg
about the size of Manhattan

3
00:00:53,780 --> 00:00:58,440
breaking off a cliff in Greenland
to drift out and melt into the ocean.

4
00:00:59,600 --> 00:01:02,890
The Arctic region is melting
as it's heated twice as fast

5
00:01:02,890 --> 00:01:04,510
as the rest of the planet,

6
00:01:04,510 --> 00:01:08,210
and science every day brings us news,
alarming news, from the North.

7
00:01:08,210 --> 00:01:11,810
Science tend to always bring us
bad news from the North.

8
00:01:12,050 --> 00:01:14,100
Just yesterday it was announced

9
00:01:14,100 --> 00:01:17,750
that this April is the warmest
we've ever experienced.

10
00:01:17,750 --> 00:01:19,930
In certain parts of Greenland,

11
00:01:19,930 --> 00:01:23,209
it was not one degree warmer,
not two degrees warmer,

12
00:01:23,209 --> 00:01:27,150
it was nine and a half degrees warmer
than normal April's would be.

13
00:01:27,990 --> 00:01:34,630
So I think the Arctic has become a symbol
of global change and pending disaster.

14
00:01:35,850 --> 00:01:39,590
I was myself born in Greenland
a very long time ago.

15
00:01:40,390 --> 00:01:45,410
I came from Greenland to Denmark
and the U.S. to become a scientist,

16
00:01:45,410 --> 00:01:49,550
to study geology with the one purpose
of being able to come back

17
00:01:49,550 --> 00:01:55,180
and do my fieldwork every summer
in the vast Arctic nature.

18
00:01:56,290 --> 00:01:58,750
I think it's kind of misleading

19
00:01:58,750 --> 00:02:03,970
that the Arctic has gotten this emblem
of being a symbol of disaster

20
00:02:03,970 --> 00:02:08,249
because the reason why we,
as scientists, go into the Arctic

21
00:02:08,249 --> 00:02:12,020
is because the Arctic is the most
wonderful region on the planet.

22
00:02:12,750 --> 00:02:15,640
It is the most beautiful place
and every scientist I know,

23
00:02:15,640 --> 00:02:19,160
they go to the Arctic
with that one particular reason:

24
00:02:19,170 --> 00:02:21,030
to be in this beautiful place.

25
00:02:21,030 --> 00:02:24,560
In contrast to what we see, those of us
who live in the Arctic, of course,

26
00:02:24,560 --> 00:02:28,880
industries see another property
of the Arctic: they see opportunity.

27
00:02:28,880 --> 00:02:32,110
The heating of the Arctic
is supposed to give access

28
00:02:32,110 --> 00:02:36,959
to new mineral resources;
oil, gas, gold, fish, whatever,

29
00:02:36,959 --> 00:02:39,959
and the business plan seems to be,

30
00:02:40,589 --> 00:02:44,489
"Let us go and exploit and scavenge
the last drop of everything

31
00:02:44,489 --> 00:02:47,310
that is left in that last place on Earth

32
00:02:47,310 --> 00:02:50,190
that has not yet
been destroyed by humankind."

33
00:02:50,680 --> 00:02:53,960
I think the question
that I would like to pose today is:

34
00:02:54,520 --> 00:02:56,919
Is that really the best idea
we can come up with

35
00:02:56,919 --> 00:02:59,669
and do exactly the same
that has destroyed everywhere else

36
00:02:59,680 --> 00:03:02,500
in the last place
that has not been destroyed yet?

37
00:03:03,690 --> 00:03:08,490
My suggestion is that we cannot risk
to do those vast expanses

38
00:03:08,490 --> 00:03:11,110
of undestroyed nature
that the Arctic still possesses,

39
00:03:11,110 --> 00:03:16,450
and we have to use our research capacity
to try and come up with something

40
00:03:16,450 --> 00:03:21,480
that is more smart, and more sustainablem
and more long-term benefit for mankind.

41
00:03:21,700 --> 00:03:25,080
I suggest that instead of doing
what we had done everywhere else,

42
00:03:25,080 --> 00:03:26,880
we should do something new,

43
00:03:26,880 --> 00:03:30,940
and we should find out
what are the true values of the Arctic.

44
00:03:32,750 --> 00:03:35,420
I have a specific suggestion,

45
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

46
00:03:42,550 --> 00:03:46,470
to actually fight problems
otherwhere on the planet.

47
00:03:46,470 --> 00:03:51,910
One of the major problems we have
beside the climate change, of course,

48
00:03:51,910 --> 00:03:54,710
is inequality and food security.

49
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,

50
00:04:00,240 --> 00:04:02,350
some regions are rich, some are poor.

51
00:04:02,350 --> 00:04:06,040
The rich regions, which are not
what's shown on this map,

52
00:04:06,040 --> 00:04:09,040
but could as well have been,
this map shows soil quality.

53
00:04:09,040 --> 00:04:12,440
It shows where the crops that,
as coming from the fields,

54
00:04:12,440 --> 00:04:14,110
are richest on the planet.

55
00:04:14,110 --> 00:04:18,080
You see that richness couples completely
with where the soil was good.

56
00:04:18,080 --> 00:04:23,840
The reason for this is not
that the soil has always been like that,

57
00:04:23,840 --> 00:04:28,300
it is because the soil was replenished
with minerals during the last ice age.

58
00:04:28,300 --> 00:04:31,100
Ice came down from the north,
scoured the rocks,

59
00:04:31,100 --> 00:04:34,900
turned it into a fine powder
and dumped it in front of the glaciers

60
00:04:34,900 --> 00:04:38,040
and fertilized the grounds across
North America, Europe, and Asia,

61
00:04:38,040 --> 00:04:41,170
and that's where everything
that feeds humankind today grows.

62
00:04:41,410 --> 00:04:44,150
On the other hand,
if you look into the tropics,

63
00:04:44,150 --> 00:04:48,130
you have red barren soils
with very poor fertility,

64
00:04:48,140 --> 00:04:51,580
and that is the reason
why people in the tropics are poor,

65
00:04:51,580 --> 00:04:53,940
why we have malnutrition
and undernutrition,

66
00:04:53,940 --> 00:04:58,190
because these soils are basically
impossible to grow crops on.

67
00:04:58,190 --> 00:05:00,060
My suggestion is very simple.

68
00:05:00,060 --> 00:05:06,290
In Greenland, where we have the last bit
of the ice cap in the Northern Hemisphere,

69
00:05:06,510 --> 00:05:09,070
and it's melting right now,
it's been melting forever,

70
00:05:09,070 --> 00:05:10,680
but now it's melting faster,

71
00:05:10,680 --> 00:05:15,220
it's flushing out billions of tons
of very finely ground rock flour

72
00:05:15,220 --> 00:05:18,760
that contains all the mineral nutrients
that are missing in the tropics.

73
00:05:18,770 --> 00:05:23,610
The idea is that we take that mud,
this material from Greenland,

74
00:05:23,610 --> 00:05:27,280
transferred to the tropical regions
and spread it on the ground,

75
00:05:27,280 --> 00:05:31,160
where it will re-fertilize the soil
and provide for new wealth

76
00:05:31,160 --> 00:05:33,110
and new development in these countries.

77
00:05:33,110 --> 00:05:35,360
At the same time the Arctic region

78
00:05:35,370 --> 00:05:39,380
is also, of course, needing
development and new trades

79
00:05:39,380 --> 00:05:42,700
but rather than doing the same again
as we have done everywhere else,

80
00:05:42,700 --> 00:05:45,230
we could do something
to develop the Arctic

81
00:05:45,230 --> 00:05:48,870
that at the same time does something good
in the rest of the world.

82
00:05:49,370 --> 00:05:51,890
My suggestion is again
that we take the mud

83
00:05:51,890 --> 00:05:56,150
coming out of the glaciers in Greenland
and take it to the tropics,

84
00:05:56,150 --> 00:05:59,780
because the mud that you find in Greenland
is unlike any other mud you find.

85
00:05:59,780 --> 00:06:03,950
The mud you have in the Amazon,
the Mississippi, or any other major river,

86
00:06:03,950 --> 00:06:08,720
is what's leftover after all the nutrients
have been sucked out of the ground,

87
00:06:08,720 --> 00:06:11,060
and the leftovers
are flushed down the river.

88
00:06:11,060 --> 00:06:16,210
Whereas in Greenland, it has,
intact all the minerals

89
00:06:16,210 --> 00:06:17,960
that plants need to grow in.

90
00:06:18,940 --> 00:06:23,680
In Greenland this is dumped by the rivers
in the fjords, the valleys, and the lakes,

91
00:06:23,680 --> 00:06:26,960
and it's very easy to take it
without making a large industry

92
00:06:26,960 --> 00:06:29,350
without having
any chemical treatment, anything.

93
00:06:29,600 --> 00:06:34,200
You basically just take up this stuff
and take it to where it's needed.

94
00:06:35,670 --> 00:06:37,690
That, of course, begs a new question:

95
00:06:37,690 --> 00:06:41,740
Is that really a good idea to take
millions of tons of something

96
00:06:41,740 --> 00:06:45,660
from someplace on Earth
and take it to some other part of Earth?

97
00:06:45,660 --> 00:06:48,100
Isn't that another climate threat?

98
00:06:48,100 --> 00:06:51,340
Is that not something that's going
to make our problem even greater?

99
00:06:51,340 --> 00:06:54,740
My suggestion is that it's not,
because the good news is

100
00:06:54,740 --> 00:06:57,980
that the mechanism by which
the nutrients are released

101
00:06:57,980 --> 00:07:01,720
from this material to the plants
is a process we call "weathering":

102
00:07:01,720 --> 00:07:04,490
weathering is when something, minerals,

103
00:07:04,490 --> 00:07:07,360
react the carbon dioxide
from the atmosphere.

104
00:07:07,750 --> 00:07:10,290
We take this, spread it
on the tropical soils.

105
00:07:10,290 --> 00:07:13,700
What happens is that it will start
reacting the CO2 from the atmosphere

106
00:07:13,700 --> 00:07:15,450
and draw it out of the atmosphere.

107
00:07:15,450 --> 00:07:19,240
We can calculate that
by transporting this material

108
00:07:19,240 --> 00:07:21,400
from the Arctic to the tropics,

109
00:07:21,400 --> 00:07:25,430
we actually emit less CO2 in the process

110
00:07:25,430 --> 00:07:30,539
than we consume by the reaction
of this material with the atmosphere.

111
00:07:30,539 --> 00:07:36,829
My suggestion is that Greenlandic
glacier mud can be a solution

112
00:07:36,829 --> 00:07:41,550
to problems like hunger
and poverty in the tropics,

113
00:07:41,560 --> 00:07:43,590
also it will lower the incentive

114
00:07:43,590 --> 00:07:47,770
to cut rainforest to make
new land for agriculture.

115
00:07:49,410 --> 00:07:50,989
Therefore I will suggest

116
00:07:50,989 --> 00:07:55,580
that the Arctic could be
a source of good news finally.

117
00:07:56,450 --> 00:07:59,940
I will say that Greenland
is not called "Greenland" for nothing,

118
00:07:59,940 --> 00:08:03,040
it's actually the place
that could make parts of the Earth

119
00:08:03,040 --> 00:08:06,240
that is now barren green
as we see Greenland is here.

120
00:08:06,240 --> 00:08:08,550
So it's time for good news from the North.

121
00:08:08,550 --> 00:08:11,250
(Applause)
