1
00:00:00,835 --> 00:00:03,877
I consider it my life's mission

2
00:00:03,877 --> 00:00:08,150
to convey the urgency
of climate change through my work.

3
00:00:08,150 --> 00:00:11,726
I've traveled north to the Arctic
to the capture the unfolding story

4
00:00:11,726 --> 00:00:13,281
of polar melt,

5
00:00:13,281 --> 00:00:17,740
and south to the equator to document
the subsequent rising seas.

6
00:00:17,740 --> 00:00:21,455
Most recently, I visited
the icy coast of Greenland

7
00:00:21,455 --> 00:00:24,404
and the low-lying islands of the Maldives,

8
00:00:24,404 --> 00:00:29,582
connecting two seemingly disparate
but equally endangered

9
00:00:29,582 --> 00:00:31,672
parts of our planet.

10
00:00:31,672 --> 00:00:34,342
My drawings explore moments

11
00:00:34,342 --> 00:00:34,592
of transition, turbulence,

12
00:00:37,337 --> 00:00:40,309
and tranquility in the landscape,

13
00:00:40,309 --> 00:00:43,815
allowing viewers to emotionally connect

14
00:00:43,815 --> 00:00:47,368
with a place you might never have
the chance to visit.

15
00:00:47,368 --> 00:00:49,388
I choose to convey the beauty

16
00:00:49,388 --> 00:00:52,105
as opposed to the devastation.

17
00:00:52,105 --> 00:00:55,217
If you can experience

18
00:00:55,217 --> 00:00:56,888
the sublimity of these landscapes,

19
00:00:56,888 --> 00:01:01,625
perhaps you'll be inspired
to protect and preserve them.

20
00:01:01,625 --> 00:01:05,015
Behavioral psychology tells us
that we take action

21
00:01:05,015 --> 00:01:09,497
and make decisions based
on our emotions above all else,

22
00:01:09,497 --> 00:01:12,957
and studies have shown that art
impacts our emotions

23
00:01:12,957 --> 00:01:17,368
more effectively than a scary news report.

24
00:01:17,368 --> 00:01:23,638
Experts predict ice-free Arctic summers
as early as 2020,

25
00:01:28,510 --> 00:01:29,114
and sea levels are likely to rise
between two and 10 feet

26
00:01:29,300 --> 00:01:30,507
by century's end.

27
00:01:30,507 --> 00:01:34,710
I have dedicated my career
to illuminating these projections

28
00:01:34,710 --> 00:01:37,311
with an accessible medium,

29
00:01:37,311 --> 00:01:42,907
one that moves us in a way
that statistics may not.

30
00:01:42,907 --> 00:01:45,531
My process begins with traveling
to the places

31
00:01:45,531 --> 00:01:47,853
at the forefront of climate change.

32
00:01:47,853 --> 00:01:50,569
On site, I take thousands of photographs,

33
00:01:50,569 --> 00:01:54,958
and back in the studio, I work
from both my memory of the experience

34
00:01:54,958 --> 00:01:58,650
and the photographs to create
very large-scale compositions,

35
00:01:58,650 --> 00:02:01,412
sometimes over 10 feet wide.

36
00:02:01,412 --> 00:02:04,245
I draw with soft pastel, which is dry,

37
00:02:04,245 --> 00:02:06,520
like charcoal, but colors.

38
00:02:06,520 --> 00:02:10,235
I consider my work drawings,
but others call them painting.

39
00:02:10,235 --> 00:02:14,461
I cringe, though, when I'm referred to
as a "finger painter."

40
00:02:14,461 --> 00:02:15,901
(Laughter)

41
00:02:15,901 --> 00:02:20,220
But I don't use any tools and I
have always used my fingers and palms

42
00:02:20,220 --> 00:02:23,656
to manipulate the pigment on the paper.

43
00:02:23,656 --> 00:02:28,208
Drawing is a form of meditation for me.

44
00:02:28,208 --> 00:02:30,437
It quiets my mind.

45
00:02:30,437 --> 00:02:33,734
I don't perceive what I'm drawing
as ice or water.

46
00:02:33,734 --> 00:02:40,352
Instead, the image is stripped down
to its most basic form of color and shape.

47
00:02:40,352 --> 00:02:45,483
Once the piece is complete, I can finally
experience the composition as a whole

48
00:02:45,483 --> 00:02:48,246
as an iceberg floating
through glassy water,

49
00:02:48,246 --> 00:02:52,472
or a wave cresting with foam.

50
00:02:52,472 --> 00:02:54,586
On average, a piece this size

51
00:02:54,586 --> 00:02:57,976
takes me about,
as you can see, 10 seconds.

52
00:02:57,976 --> 00:03:01,969
(Laughter) (Applause)

53
00:03:03,757 --> 00:03:07,983
Really more like 200 hours,
250 hours for something that size.

54
00:03:07,983 --> 00:03:10,793
But I've been drawing ever since
I could hold a crayon, really.

55
00:03:10,793 --> 00:03:14,322
My mom was an artist, and growing up,
we always had art supplies

56
00:03:14,322 --> 00:03:15,507
all over the house.

57
00:03:15,507 --> 00:03:18,757
My mother's love of photography
propelled her to the most

58
00:03:18,757 --> 00:03:21,405
remote regions of the Earth,

59
00:03:21,405 --> 00:03:25,259
and my family and I were fortunate enough
to join and support her

60
00:03:25,259 --> 00:03:27,047
on these adventures.

61
00:03:27,047 --> 00:03:30,019
We rode camels in northern Africa

62
00:03:30,019 --> 00:03:33,990
and mushing on dog sleds
near the North Pole.

63
00:03:33,990 --> 00:03:38,139
In August of 2012,
I led my first expedition,

64
00:03:38,139 --> 00:03:43,317
taking a group of artists and scholars
up the northwest coast of Greenland.

65
00:03:43,317 --> 00:03:47,358
My mother was originally
supposed to lead this trip.

66
00:03:47,358 --> 00:03:49,982
She and I were in
the early stages of planning,

67
00:03:49,982 --> 00:03:52,280
as we had intended to go together,

68
00:03:52,280 --> 00:03:56,042
when she fell victim to a brain tumor.

69
00:03:56,042 --> 00:03:59,943
The cancer quickly took over
her body and mind,

70
00:03:59,943 --> 00:04:02,799
and she passed away six months later.

71
00:04:02,799 --> 00:04:07,745
During the months of her illness, though,
her dedication to the expedition

72
00:04:07,745 --> 00:04:12,668
never wavered, and I made a promise
to carry out her final journey.

73
00:04:13,550 --> 00:04:16,383
My mother's passion for the Arctic

74
00:04:16,383 --> 00:04:19,819
echoed through my experience in Greenland,

75
00:04:19,819 --> 00:04:22,768
and I felt the power

76
00:04:22,768 --> 00:04:26,205
and the fragility of the landscape.

77
00:04:26,205 --> 00:04:29,572
The sheer size of the icebergs

78
00:04:29,572 --> 00:04:31,359
is humbling.

79
00:04:31,359 --> 00:04:37,164
The ice fields are alive with movement
and sound in a way that I never expected.

80
00:04:37,164 --> 00:04:39,556
I expanded the scale of my compositions

81
00:04:39,556 --> 00:04:42,970
to give you that same sense of awe

82
00:04:42,970 --> 00:04:45,268
that I experienced.

83
00:04:45,268 --> 00:04:48,867
Yet, while the grandeur
of the ice is evident,

84
00:04:48,867 --> 00:04:51,329
so too is its vulnerability.

85
00:04:51,329 --> 00:04:54,185
From our boat, I could see the ice

86
00:04:54,185 --> 00:04:57,830
sweating under the unseasonably warm sun.

87
00:04:57,830 --> 00:05:02,567
We had a chance to visit
many of the Inuit communities in Greenland

88
00:05:02,567 --> 00:05:05,330
that now face huge challenges.

89
00:05:05,330 --> 00:05:08,721
The locals spoke to me
of vast areas of sea ice

90
00:05:08,721 --> 00:05:11,577
that are no longer freezing over
as they once did,

91
00:05:11,577 --> 00:05:14,409
and without ice, their hunting
and harvesting grounds

92
00:05:14,409 --> 00:05:16,476
are severely diminished,

93
00:05:16,476 --> 00:05:20,446
threatening their way
of life and survival.

94
00:05:20,446 --> 00:05:24,742
The melting glaciers in Greenland are
one of the largest contributing factors

95
00:05:24,742 --> 00:05:26,902
to rising sea levels,

96
00:05:26,902 --> 00:05:33,125
which have already begun to drown
some of our world's lowest lying islands.

97
00:05:33,125 --> 00:05:37,327
One year after my trip to Greenland,
I visited the Maldives,

98
00:05:37,327 --> 00:05:40,880
the lowest and flattest country
in the entire world.

99
00:05:40,880 --> 00:05:45,269
While I was there, I collected
images and inspiration

100
00:05:45,269 --> 00:05:47,289
for a new body of work:

101
00:05:47,289 --> 00:05:51,113
drawings of waves lapping
on the coast of a nation

102
00:05:51,113 --> 00:05:53,783
that could be entirely underwater
within this century.

103
00:05:53,783 --> 00:06:01,214
Devastating events happen every day

104
00:06:01,214 --> 00:06:05,115
on scales both global and personal.

105
00:06:05,115 --> 00:06:08,063
When I was in Greenland,
I scattered my mother's ashes

106
00:06:08,063 --> 00:06:10,966
amidst the melting ice.

107
00:06:10,966 --> 00:06:15,796
Now she remains a part
of the landscape she loved so much,

108
00:06:15,796 --> 00:06:21,183
even as it too passes
and takes on new form.

109
00:06:21,183 --> 00:06:27,220
Among the many gifts my mother gave me
was the ability to focus on the positive

110
00:06:27,220 --> 00:06:29,171
rather than the negative.

111
00:06:29,171 --> 00:06:36,044
My drawings celebrate the beauty
of what we all stand to lose.

112
00:06:36,044 --> 00:06:41,663
I hope they conserve as records
of sublime landscapes in flux,

113
00:06:41,663 --> 00:06:46,446
documenting the transition
and inspiring our global community

114
00:06:46,446 --> 00:06:49,325
to take action for the future.

115
00:06:49,325 --> 00:06:50,974
Thank you.

116
00:06:50,974 --> 00:06:56,059
(Applause)
